Recent Additions to the Prehistoric Circus

Here are the final pieces in the Prehistoric Circus series that I have worked on for the past two years. This series focuses on placing prehistoric animals in a circus setting, allowing the viewer to encounter the unknown, the exotic, and the amazing mammals that lived millions of years ago.


The nostalgia of the circus provides a connection to the child like joy I find in discovering new animals for the first time. Elements of the circus in each piece create an alternate timeline in which the viewer can travel back and experience the power of these majestic animals. They find themselves on velvet cushions swaying on the back of an ancient giant in an unknown landscape. Colors and intricate patterns are fading; the paint peels and wood rots away under heavy feet and wrinkled hide. As time passes, the animals march on and adapt. Enduring the years like a weathered tapestry, they become the animals we know today.

Each piece has a unique pattern. I start each pattern with light sketching like a pencil drawing. Some patterns get filled in with small stamps, or other embellishments. I also leave blank spaces in the pattern to be filled in later with decals, or transfers.




Many of my ideas for patterns are copied, or originate from Hindu patterns, and tiles from Iran like these. A lot of the patterns in the Hindu religion center around a Mandala, literally meaning circle. This circle is meant to draw in the human consciousness. The concentric design is meant to help people meditate and directs the mind to focus inward. Mandalas are also very balanced patterns that symbolize unity and harmony. I get lost when I carve these complex patterns, and its very meditative. It reminds me of the feeling I get when I lose myself in nature. When I walk in the woods I don’t have to get anywhere, or do anything, and I can be alone with my thoughts.

Magnificant Migration-099

Each of my pieces is made individually, and usually carved from a solid block. I use some small molds for patterns, and embellishment, but no molds are used for the animal forms. Each animal is carved or built from a solid block of clay, hollowed and reassembled.


I often use slab building to help me create some of the parts of my pieces. These tents were constructed and then added to the hollowed animal form. The patterns were carved and added last.


A lot of the pieces I made in this series were designed to march in a large parade. This parade was inspired by images of animals migrating in the wild, and the way they seemed to be on parade. I connected this to the free street parade that every circus gave to a new town it had arrived in. It was a way to display the animals, and various acts, and make people want to come and see the circus.



This inspired other pieces involving musical instruments, chariots, along with strange prehistoric animals to pull them.

Magnificant Migration-114These small pig-like animals are actually the earliest known elephant, Moertherium that lived 37 million years ago.  They are also distantly related to the sea cow. They looked a lot like pigs, or the modern day tapir. They were much smaller than their later relatives. Moeritheirum was believed to have spent a lot time in the water eating aquatic vegetation.

Much of the distressed surfaces in these pieces was inspired by my dad. He restores antique furniture, and I grew up watching chipped and cracking gold leaf enter his shop, and the beautiful, glittering, gilded surfaces that would leave it. I loved the way that these objects had stood the test of time, with so much original bright gold still shining through layers of dirt and grime. Their history was revealed in their destruction, but also their ability to survive. The aesthetic in my work is meant to show the beauty in objects that are weathered and worn.

The newest parade elephant is based on one of the strangest prehistoric elephant that I have researched. Platybelodon lived 15 million years ago. Platybelodon was in a special genus of elephants called gompotheres. This means that they had two sets of tusks, the top tusks being pointed, and the lower ones being flat like shovels. These shovel like tusks were believed to help them scoop up aquatic vegetation.

Size: 8 feet tall, weighing 5 tons

Location: Asia, Africa, and North America

Magnificant Migration-175

A Colossal Collapse is another Dumbo-inspired pyramid of prehistoric elephants. I love making these stacks of elephants because they are so precarious. The balance in them echoes the balance in nature, and how each animal is connected to the success of another. I also enjoy placing prehistoric elephants that existed in different times together in one piece. This idea was inspired by the paintings of Dutch still life painter Rachel Ruysch. Her paintings show flowers that bloom at different times of the year in the same bouquet. So this is an impossible composition that could never actually exist, but the fantasy creates something beautiful. I also love how she includes insects, and dying flowers in a lot of her work, to show the passage of time and the way decay in nature leads to new life.


These stacks of elephants start out like all my sculptures, as a solid mass on an armature. The difference here is that each elephant is slowly revealed from the mass and the clay eventually cut away from between the legs. The clay must be allowed to get dry to hold itself up, but not completely dry. This stiffness in ceramics is called leatherhard; the clay is flexible, but also able to be wet down and added to. Once this is achieved and the elephant forms are revealed, I cut each one off the other and pull it off the pipe armature you see here. I hollow each elephant, then reassemble the pyramid.




Detail being added to the hollowed, and reattached elephants.


Unfortunately, this top piece did not fit in my kiln! So the last elephant had to be fired separately and glued on. This is common in my practice. I am often using mixed media materials, and various epoxies to make my ideas a reality. I think the seemingly impossible balance in these pieces comes from the way I build them as one piece on an armature. the vertical pipes provide a perfect center of balance for the piece. This one did not need anything to help it balance on its own once it was fired.

Hans the High Flyer is another giant ground sloth, though probably more acrobatic than the animal that inspired him. Giant ground sloths could be up to 20 ft. tall! I love the humor in this piece, and when he hangs in a gallery he swings just a little.

The Prehistoric Circus will be displayed in a solo exhibition at the Beatrice M. Haggerty Gallery at the University of Dallas in January 2016.

Even though this pivotal series has come to an end, I see many more animals on the horizon. I am currently beginning my graduate study in ceramics at the University of Florida. I have a lot of ideas for new pieces and will be documenting my experiments, research, and process right here.

The Prehistoric Circus: Process and Concept

The Prehistoric Circus is my most recent series of ceramic sculptures. Here I will discuss the process involved with these pieces, the prehistoric mammals they are inspired by, and the concepts behind them.

1150631_971265690634_203117654_oI always start with an armature and start packing clay onto it in a solid mass. The armature can vary depending on the pose and size of the piece I am sculpting.

20130930_153449Once the piece is roughed out enough I can begin hollowing. I leave all detail until after the hollowing process because I will have to cut through the solid piece.


The hollowing process often takes much longer than it took to sculpt the solid form. On larger pieces hollowing can take up to one week. I make sure all the walls are as thin as possible, compressed, and even, so I do not have to use any internal structures.

20140101_165214Once pieces are reassembled I start carving in all fine details and textures. Thin, or delicate parts like ears, tails and trunks will be put on as late as possible to prevent them from drying out while all the detail is being done.

???????????????????????????????All detail is a combination of techniques. Patterns like this one are drawn on first by hand, then embellished with carving, stamping, and later stencils and patterns.


Some of the embellishments are made using a plaster press mold of machined patterns. I can press wet clay into this mold to get an impression of something more architectural for some pieces.

20130916_171904Once all detail is completed pieces are bisque fired once to cone 04 (1940 degrees F) before any glazes are applied.

DSC05008After the bisque firing, stains and glazes are applied in several layers. Sanding through and roughing the surface of these layers gives the effect of an aged surface.


The surfaces on my pieces all start with layers of stains, slips or underglazes. These are often followed by engobes and or more underglaze.


I often use paper cut out stencils, rice paper decals, and slip trailers to add pattern to areas that I left blank of any carving or stamping in the wet clay. This gives the surfaces depth by showing both printed and carved elements together, and creates a more mysterious looking surface.

DSC05120I usually hand paint most of the color in using small brushes. On pieces like the elephants, one layer of their skin is done first, then the pattern and colors on the blankets are completely finished before I apply the crawling skin glaze to the elephant body. This is so runs and drips don’t ruin the finished skin surface while I work on the blankets.

DSC05103The half way point of the glazing I do looks finished, but this is before I do the distressing on the surface that makes the pieces look older. Once I reach this point, I sand off the dry, but not fired, glazes and slips in places. This reveals the layers of darker color, stain or engobe underneath and makes the surface look worn. I also use an exacto knife to make the painted surface look chipped off in places. After that, a brown, or black underglaze wash is applied with a spray bottle to create runs and stains. Until the piece looks more like this.

DSC05090After the piece is fired I will do a copper carbonate wash. This creates a dingy effect in some places.

Prehistoric Circus-26

Some of the pieces receive a cold finish surface, meaning I use non fired materials like paint, or wood stain.  In this piece the base is a ceramic surface, and the saber cat is a cold finish using house paint and wax encaustic.


Here are some of the finished pieces from these processes, as well as the information about the animals. The prehistoric circus is a series that is inspiring me to create sculptures of animals that bring joy and interest to the audience. Most exotic or strange animals were at one point, only seen at the circus. I use the circus setting to display these fascinating prehistoric animals in a grand setting and introduce them to viewer. I hope that this allows people to experience the wonder and excitement I feel when I discover that these animals actually existed and their amazing feats of evolution.

Bozo the Dodo

The Dodo:

This commonly known prehistoric bird dates back almost 45 million years ago. The first recorded mention of the Dodo was by Dutch sailors in 1598. In the following years, the bird was hunted by sailors, their domesticated animals, and invasive species introduced during that time. The last known of the species went extinct in the 17th Century leaving behind their closest living relatives the Nicobar pigeon.

Size: 3 ft. tall, weighing 20-40 lbs.

Cage Wagon I

Pulled by Brontoherium (Megacerops)

This species of rhinoceros lived about 40 million years ago. Brontotherium had a pair of blunt horns on their snout with the horns of males being much larger than those of the females. Despite resembling a rhinoceros, it was larger than any living rhinoceros: the living animal easily approached the size of the African forest elephant, the third largest land animal today.

Size: 8.2 feet at the shoulder

Location: North America

Cage holding Dinofelis

A saber-toothed cat that lived about 8 million years ago. In size they were between a modern leopard and a lion, most being about the size of a jaguar, medium-sized but powerful cats that possessed two prominent sabre teeth.

Size: 2-3 feet tall

Location: Europe, Asia, Africa, and North America

Gunter the Miraculous Megatherium



A giant ground sloth that lived 5 million years ago. Megatherium was the largest of ground sloths that ranged in size. This animal’s large claws were believed to be used to scrape leaves off of branches. Megatherium is believed to be an omnivore like some modern day bears.

Size: About 20 ft. tall, weighing 4 tons

Colombian Mammoth

The Columbian mammoth was a savanna and grassland inhabitant, similar to the modern African elephant that lived 2 million years ago. A pair of Columbian Mammoth tusks discovered in central Texas was the largest ever found for any member of the elephant family at 16 feet long. The Waco Mammoth Site in Waco, TX holds the record for the largest known concentration of skeletons of mammoths believed to have died in the same event

King of Cats


Smilodon Fatalis

The best known of prehistoric cats, also known as the saber-toothed tiger lived 2.5 million years ago. However, Smilodon is not related to the tiger or any other living big cat today. Many of the best fossils found of smilodon were discovered at the La Brea Tar Pits. Overall, Smilodon was more robustly built than any modern cat, with particularly well-developed forelimbs and exceptionally long upper canines. Its jaw had a bigger gape than modern cats and its upper canines were slender and fragile, being adapted for precision killing. These attributes made Smilodon a specialized hunter of large herbivores like bison and camels.

Size: About 6 ft. long, weighing close to 500 lbs.

The Balloon Horse Jupiter


This extinct horse lived about 20 million years ago. It had three toes on each foot, two small toes on either side of a main hoof. This is the first horse known to have grazed. Merychippus is very closely related to the modern day horse, and it was the first equine to have the distinctive head shape of today’s horses.

Kala Nag

Palaeoloxodon Antiquus (The Straight Tusked Elephant)

One of the earliest species of elephant that lived 400,000 years ago, closely related to the modern day Asian elephant. Palaeoloxodon antiquus was a forest elephant, and was the largest species living in Europe until the end of the Pleistocene epoch.

Size: 13 ft. at the shoulder and up to 14 ft. long

Location: Bilzingsleben, Germany, Cyprus, Japan, Sicily and Malta

Silver Star


An early horse species that lived 50 million years ago. Distinctive features include four small hoof-like toes on the front feet and three toes on the hind feet. These toes eventually evolved into the single hoof on horses we know today.

Size: 2 ft. at the shoulder

Location: North America, Wyoming and Oregon

A Mighty Mountain of Mammoths

Anancus (Center)

This prehistoric elephant lived about 9 million years ago. It had two tusks, whereas most other gomphotheres had four. Aside from its somewhat shorter legs, Anancus was also different from modern elephants in that its tusks were much longer, up to 4 metres (13 ft) in length. The tusks were possibly defense weapons not unlike elephants of today.

Size: 9 ft. tall, weighing 6 tons

Location: Africa, Europe, and Asia

Cuvieronius (Sides)

A prehistoric elephant that existed 5 million years ago. Cuvieronius is famous for being one of the few prehistoric elephants (the only other documented example is Stegomastodon) to have colonized South America, taking advantage of the “Great American Interchange” that connected North and South America a few million years ago. This smallish elephant was distinguished by its long, spiraling tusks, reminiscent of those found on a narwhal.

Size: 9 ft. tall

Location: North America and South America

Palaeoartistry: Sculpting at the Fort Worth Museum of Science and History


I recently participated in an event called iPLAY at the Fort Worth Museum of Science and History. This event was created to celebrate the combination of science and technology with art. As a demonstrator I showed my techniques for sculpting prehistoric animals using animal anatomy and science as tools to recreate an extinct animal.

For this demonstration I sculpted Megaloceros, also known as the Irish Elk. This prehistoric elk had an antler span of about 12 feet, and was over 6 feet tall. Here is an illustration by another palaeoartist, Charles R. Knight.

CK1Tlascaux-elkThis painted image of Megaloceros is from the Lascaux cave in France. These cave paintings are some of the earliest palaeoart, describing the animals in detail.

DSC01573Here is Megaloceros as I first saw him at the Paris Natural History Museum. In the glass case you can see another palaoartist’s bronze reconstruction. Museums often use palaeoart to show people what extinct species might have looked like. I use skeletons like this one along with modern day descendants of the animal I am sculpting to get a realistic reconstruction. For this piece I used the elk as my main modern day anatomical reference.

970011_10151549241264109_1394291812_nMy sculpture started with a pipe armature screwed to a board and some wires inside the neck, head, and antlers. I used oil clay for this demonstration. Once finished the oil clay will be molded in rubber to make a wax version for a bronze sculpture.

1098369_10151551002039109_2094373660_nHere is the finished piece. The demonstration lasted two full days, which is about how long a piece this size takes. I had such a great time volunteering for this event at the museum. It was really fun to tell the kids that attended all about prehistoric animals like this one. Nothing comes as close to how I feel about prehistoric animals as the reactions I got from telling people that this giant deer was not made up.

The Bronze Process

The lost wax bronze casting process has a very long history in art; going back to ancient Greece when bronze sculptures were first made. The process is very long, and involves a lot of techniques and expensive equipment, so most artists go to a foundry to have their work cast.  I work part time at Schaefer Art Bronze in Arlington back in Texas. Right now while I am at the Armory I have been working on a new bronze piece. I am learning to do all the steps of the process myself. First, I started with an original sculpture.

Once this oil clay sculpture is complete it is ready for cutting and molding. a piece like this has to be cut into multiple sections to be molded because the forms are too complex to cast in one piece.

Each rhino was cut off of the base at the ankles, leaving the feet attached to the base. The rhinos were then cut in half to simplify the forms and make a nice open space on each half to pour the wax into the mold.

The base will be a  simple one piece mold. All the parts of the sculpture were set up on boards that left a 2-3 inch boarder all the way around the piece.

I used thin metal sheet to shim the seam line between the two halves of each rhino. This will be the divider between the rubber that will make it a two piece mold. Plastic keys were used to create a locking mechanism between the pieces of rubber. The pieces are all sealed with a layer of spray shellac and a layer of universal mold release. This will keep the rubber from sticking to the shims or to the oil clay.

Once the shimming was complete I used urethane rubber to make the molds of each rhino. Urethane rubber or silicone rubber is usually used to mold pieces for bronze because they release the waxes very well. Urethane molds can also be used to cast resin and some plastics. I started these molds by painting on a thin layer of the mixed rubber and once this was tacky, I was able to continue adding layers of rubber until thick enough in all areas.

When the rubber molds were completely set, the edges were trimmed and the rubber was sprayed with a few coats of epoxy parfilm. Since these molds were being made with a resin mother mold, epoxy parfilm keeps the resin from sticking to the rubber.

To make a mother mold, resin is mixed and poured out on cardboard. Fiber glass sheets are cut up into squares and patted into the resin until soaked. These are laid on the rubber and built up in several layers.

A mother mold is a hard shell that holds the rubber in the correct shape when you pour waxes. The fiber glass acts as a weave holding the resin together. This method makes a strong and lightweight mother mold.

When the resin has set the molds are ground with an angle grinder on the edges and the mother mold is pulled away from the rubber.

Once the molds were cleaned, and bolted together tightly the waxes were poured.

The waxes are removed from the molds and chased. This means that I sculpt on the wax to restore original textures and small details that were distorted in the mold and melt down seams from where the two halves met.

Because the base of this piece is so large it is cut in half. Wax rods called sprues are used in gating the waxes. Gating provides channels for the bronze metal to flow quickly and evenly to all parts of the sculpture.

The rhinos are also cast in two halves on one sprue tree. This will make it easier to dip the pieces in ceramic shell, and make the welding in the metal less difficult to work on.

Ceramic shell is a mixture of fused silica and a binder. The waxes are dipped in this mixture and then covered with fused silica sand.

The piece is dipped in the shell multiple times. The shell dries hard and solid making a negative impression of the inside and outside of each part of the sculpture, acting like a “shell”.

After the shell has dried it is fired in a burnout kiln and the wax is melted out. This firing hardens the shell so that it can then hold the molten bronze.

DSC03867After the bronze is poured and has cooled, the ceramic shell has to be broken off the metal and sandblasted clean.

20130614_154823Once the metal pieces are cast, they have to be lined up and welded. 20130614_141849Welding leaves a thick bead like a seam that then has to be ground down and made to match the texture of the piece.

20130618_114219Once all the pieces are welded together it is sandblasted clean one more time before it is given a patina.

20130619_134507To patina bronze a torch is used to heat the metal so that it can be sprayed with different chemicals. The heat allows the chemicals to react with the metal and create a color on the surface. Brushes and scrubbing pads can be used to create highlights in the patina.

Here is an image of the finished piece!

Residency Exhibition and New Work

My residency at the Armory Art Center has come to an end! I had such a great time teaching and making sculptures there!

Here are some images from my residency exhibition opening, along with some close ups of my new work.

DSC04406DSC04412DSC04414DSC04425New Work: The Prehistoric Circus

Elements of the circus in each of my sculptures represent the wonder in discovering prehistoric animals, and their amazing feats of evolution. The brightly colored drapery that adorns the broad back of an ancient giant brings about the impossible idea of a prehistoric circus; a tragic circus lost in time along with the animals themselves. Colors and intricate patterns are fading; the paint peels and wood rots away under heavy feet and wrinkled hide. My sculptures express the joy I find in the animal form while lavish decorations celebrate these creatures as the greatest show on earth.

New Pieces in Process: Saber-toothed Cat and Florida Fossils

Here is an update on some of the new pieces I have been working on at the Armory Art Center this fall. These pieces are still in the works, and all of them are at different stages in the process.

This saber cat was a much larger piece that I fired recently. I reassemble all my larger sculptures on a piece of drywall that is then burned out in the kiln. Drywall will not harm the kiln or the elements in an electric kiln, the paper burns away and the plaster moves with the piece and remains through the firing. This way I don’t have to lift the heavy or fragile piece to get it into the kiln.

First,  I raise the lift to the level of my work table and put down a little grog, this rough fired clay material acts like small ball berrings and helps the heavy sculpture slide onto the lift easily.

With the lift in place and lowered to the height of the kiln floor I can slide the drywall and the piece off the lift and into the kiln. The excess drywall is cut away after the piece is positioned. The saber cat fired for about 4 days in a small gas kiln. I always load large work at the leatherhard state so that the clay is less fragile, and any breaks that happen during loading are easy to fix.

After the piece is bisqued, I will add non ceramic elements. Since I am doing a cold finish, paints, stains, ect. on these new sculptures they won’t be needing a second firing for glazes. This saber cat will be wearing an antique leather collar. I carved a space for the collar in the wet clay, usually a little wider than necessary to account for the clay shrinking. Once the collar is in place I use Bray-poxy to sculpt additional hair that will help it look more like part of the piece. Bray-poxy is a two part epoxy putty that can be sculpted with and added to fired clay. It dries as hard as bisque clay and can be painted to match any surface. It can be purchased over the phone from the Archie Bray Foundation.

I have been experiementing with new techniques for armatures and scale as well. Here, you can see a poster in the background. This is an image I took of a maquette for this piece and then enlarged to the size I wanted the final sculpture to be. This is a great aid for sculpting as well as figuring out what size armature rods will be needed. I usually use galvanized stell pipe as an armature along with dowel rods. I am also using multiple dowel pieces taped together with electrical tape for legs and extremities. These are flexible and act as a movable joint even when clay is put over them. This allows me to change the gesture of the legs more easily.

This prehistoric deer, a blastomeryx, is life size at about 24 inches long. These types of small deer were found in a fossil pit near Tampa. Many of the modern deer in Florida are descendants of deer like this one. These deer ranged in size from a rabbit to a small dog. Their living relatives the key deer that live in the  Florida Keys. The small size of these early mammals often helped them survive climate changes and atmospheric changes that killed off much larger animals.

Welcome to Florida: The Armory Art Center Experience


This year I was accepted as an artist in residence at the Armory Art Center in West Palm Beach, Florida. Tibbers and I made it through the 20 hour drive from Dallas and I am now making work in a great studio with lots of other artists.

This year the Armory accepted six resident artists from all over the country working in ceramics, sculpture, jewelry, and painting. I will be a sculpture resident for the next 8 months. I plan to work in both clay and bronze and use non-ceramic materials on my pieces while I am here. The Armory provides a generous stipend to residents and pays artists to teach classes during their residency as well. Check out the course catalog. I am teaching classes in figure sculpture, animal sculpture, and bronze sculpture.

The first project that I started at the Armory was an original sculpture for a large bronze. I used a hard foam shape as the base and covered this with a layer of clay. The two rods have been hammered down into this foam base to hold up the rhinos.

On top of these rods I use electrical tape and dowel rods to hold up the animals and the weight of solid oil based clay.

I smear the oil clay over this structure and begin to form the rhinos. This pair of Arsinotherium, an animal that existed in Ethiopia 30 million years ago, will be charging one another similar to modern day rhinos.


With the musculature and gestures roughed out, these rhinos are ready for detail. Unlike my water based clay sculptures, these pieces do not have to be hollowed out, they will be molded as part of the bronze casting process and then the clay will be recycled, not fired.

Here is the finished oil clay sculpture with all the details and texture. There are some real rocks embedded in the base because these can be cast with the molds.

When this piece is molded, a wax version will be cast so that it can become a bronze. Check out the studio blog later on for the rest of this process! Subscribe to this blog to keep up with all the pieces I make at the Armory Art Center during my residency!
