Also present are signs of possible bone infections (osteomyelitis), as well as numerous insect borings, which suggest that the carcass was exposed for a period of time before burial. The most noticeable of these include circular perforations/punctures, some possibly being bite marks, others possibly the result of a form of the protozoan parasite Trichomonosis similar to Trichomonas gallinae, as seen in modern birds of prey (holes found in the surangular area in the lower jaws of other Tyrannosaurus specimens have been attributed to this form of Trichomonosis). In addition to the normal foramina and nutrient grooves, numerous small cracks and splits cover much of the surface of the bones, due to their having been close to the ground surface.Īll the tooth bearing jaw elements are preserved, as are most of the external bones on both right and left sides of the skull, including but not limited to these major elements - premaxillae, maxillae, nasal, jugal, lacrimal, postorbital, quadratojugal, squamosal, ectopterygoid, pterygoid, vomer, palatine, quadrate, dentaries, surangular, splenial, angular, prearticular, coronoids, and numerous upper and lower teeth.Īdding much character and individuality to the skull are several interesting pathologies. The fossilization is superb, with even small, delicate bones being preserved in fine detail. Overall, the bones are preserved in exquisite detail, exhibiting little distortion, and retaining much of their original shape and surface characteristics. Importantly there is no composite material, with the elements all belonging to one individual. The separately preserved skull elements allow for individual examination and comparison. The bones of the fossilized skull were found disarticulated, and these elements are well preserved, resulting in an informative specimen with a high degree of integrity. rex individual are indistinguishable in comparison to the adults of other species. ) Post-cranial skeletons of large tyrannosaurids are very similar, such that the bones of an immature T. ![]() This is particularly the case for Tyrannosaurus rex, as the skull is what allows palaeontologists to distinguish the phylogenetically related species (Tyrannosauridae : Daspletosaurus, Albertosaurus, Tarbosaurus, Gorgosaurus, etc. The skull is not only the most recognizable and emblematic part of the dinosaur, but also the most important from a scientific perspective.
