Pterodaustro Skull Replica

Description

Pterodaustro skull replica measures 12.5 x 2.0 x 3.0 inches. The Pterodaustro guinazui skull is a museum-quality polyurethane resin cast of a Natural History Museum of Sciences specimen. 2-part skull (separate cranium and mandible). 1:1 scale. Made in USA.

The Pterodaustro lived in South America roughly 105 million years ago. This Cretaceous pterodactyloid pterosaur had a remarkably long 29-centimeter skull. Its snout accounts for 85 percent of that total length. Both the upper and lower jaws curve sharply upward.

The lower jaw contains approximately one thousand bristle-like teeth. These structures allowed the animal to strain algae and small crustaceans from the water.

Research on these unique structures confirms they are true teeth. Because they contained enamel, dentine and a pulp they functioned like the teeth of other verterates. Despite their hard composition, the extreme length-width ratio likely allowed them to bend up to 45 degrees without breaking.

Bristles, the Pterodaustro skull replica, is on his way to adopt every dog in the Spokane County Humane Society. He bought a 40 acre ranch and fenced it to keep all of them safe.

Suchy, the Suchomimus skull replica, made a year’s supply of one-hundred percent natural homemade dog food for Bristles to feed his newly adopted fur babies.

Nanny, the Nanosaurus skull replica, sewed everyone of the dogs a new super soft and comfy bed for all of the dogs to sleep in. She placed all of the beds in Bristles’ bedroom.

Dunker, Dunkleosteus terrelli fish jaw replica, paid for all of the adoption fees and bought every dog a new collar with name tags.
