Using Ct Scans To Describe An Allosaurus Skull (Dinosauria: Theropoda), Jordan C. Oldham
Using Ct Scans To Describe An Allosaurus Skull (Dinosauria: Theropoda), Jordan C. Oldham
The Research and Scholarship Symposium (2013-2019)
In 2001, an Allosaurus skull (CMP 279) was discovered in the Skull Creek Basin in Moffat County, Colorado. The skull is one of the most complete for the species and even contains the hyoid bones, which are usually not present. The skull is now permanently mounted, for display purposes, thus making the study of the individual bones difficult for producing a paleo-anatomical description. Computed Tomography (CT) scans of CMP 279 were created in 2017 and then made available for this study in 2019. CT scans are being used to investigate internal anatomy of skulls such as the endocranial cavity, sinuses, …

A New Eusuchian Crocodyliform With Novel Cranial Integument And Its Significance For The Origin And Evolution Of Crocodylia, Casey Holliday, Nicholas Gardner

Crocodyliforms were one of the most successful groups of Mesozoic tetrapods, radiating into terrestrial, semiaquatic and marine environments, while occupying numerous trophic niches, including carnivorous, insectivorous, herbivorous, and piscivorous species. Among these taxa were the enigmatic, poorly represented flat-headed crocodyliforms from the late Cretaceous of northern Africa. Here we report a new, giant crocodyliform from the early Late Cretaceous (Cenomanian) Kem Kem Formation of Morocco. Represented by a partial braincase, the taxon has an extremely long, flat skull with large jaw and craniocervical muscles. The skull roof is ridged and ornamented with a broad, rough boss surrounded by significant vascular …
