Description
Allosaurus fragilis skull replica measures 8.5 x 3.5 x 5.1 inches. Allosaurus skull is museum-quality polyurethane resin cast from the Natural History Museum of Utah specimen. 2-part skull (separate cranium and mandible). 1:4 scale. Made in USA.
Each dentary (the tooth-bearing bone of the lower jaw) had between 14 and 17 teeth, with an average count of 16. The teeth became shorter, narrower, and more curved toward the back of the skull. All of the teeth had saw-like edges. They were shed easily, and were replaced continually, making them common fossils.
The Allosaurus skull was light, robust and equipped with dozens of sharp, serrated teeth. Its skull averaged 3.3 ft. long but could possibly reach 4.9 ft.
Inside the lacrimal bones were depressions that may have held glands, such as salt glands.
Within the maxillae were sinuses that were better developed than those of more basal theropods such as Ceratosaurus and Marshosaurus; they may have been related to the sense of smell, perhaps holding something like Jacobson’s organs. The roof of the braincase was thin, perhaps to improve thermoregulation for the brain.
