Book Description

Excerpt from On Dryptosaurus Incrassatus (Cope), From the Edmonton Series of the North West Territory Of the skulls from the Red Deer river district, the one found in 1884 on Knee Hills creek is somewhat larger than the other. In this specimen (plates IV and V) the arches are missing with the entire upper part of the cranium from the parietal region forward. The brain case is preserved, with the bones of the palate behind, as well as the posterior lower portion of the maxillxe and the anterior half of the jugals. The two rami of the mandible are almost entire. The specimen is crushed downward, and what remains of the upper part of the skull is distorted to the left, with the two rami of the mandible lying turned over, beneath. The two halves of the Jew have been displaced, posteriorly, so as to partially expose the bones of the back portion of the palate in the space between them. This displacement of the jaw has brought to view the inner surface of the right ramus, which lies, posteriorly, almost in the same plane as the exposed outer surface of the left ramus. From this specimen we gain information regarding the form and con struction of the brain case and the anterior part of the lower or infratemporal arcade, the composition of the palate and the shape of the several elements of the mandible with their relations to each other.
