The Art of Articulation: Building Skeletons

Where do these skeletons come from? How are they prepared?

Step one is picking up the specimen

After an animal pass away at a zoo, aquarium, wildlife center, or nature preserve, the animal is donated to the museum. The animal can either be sent to our Processing Division in Oklahoma City, OK or it is collected in person by one of our trained technicians.

Step two is removing the flesh

After the animal reaches the processing center at Skulls Unlimited, the animal is prepared for flensing, or flesh removal. Skulls Unlimited is the parent company of the museum. They clean and supply specimens to many medical, veterinary, zoological, and forensic institutions.

Factors influencing cleaning 

Some bones are too big to be cleaned by beetles. There are several different methods used to remove tissue. The most common method we use is manual removal followed by the beetles. actors to consider in processing are the age of the animal, size, and current state of decomposition.

Step four is chemically whitening the bones

After the bones have no traces of flesh or cartilage, they are then put in a special solution consisting of hydrogen peroxide to whiten and sanitize. This process oxygenates the bones leaving them clean, white, and ready for display.

Step five is skeletal articulation

All the individual bones are then inventoried and reassembled by hand. We call this process articulation.  Our articulators have an advanced knowledge of anatomy to drill, wire, glue, and position each bone back together. Each skeleton takes a minimum of 15 hours to assemble.

The final product

After all those steps, the museum gets a brand-new specimen to display and for guests to enjoy. Guests are encouraged to touch and examine our articulated skeletons on display.

An articulator's work is never finished

New specimens continue to be donated to the museum's comparative collection, which includes around 8,000 total specimens, representing over 1,500 species. Each day, our team at Skull Unlimited works to preserve these skeletons and produce the best articulations in the world.
