Fused and Vaulted Nasals of Tyrannosaurid Dinosaurs: Implications for Cranial Strength and Feeding Mechanics
Fused and vaulted nasals of tyrannosaurid dinosaurs: Implications for cranial strength and feeding mechanics ERIC SNIVELY, DONALD M. HENDERSON, and DOUG S. PHILLIPS Snively, E., Henderson, D.M., and Phillips, D.S. 2006. Fused and vaulted nasals of tyrannosaurid dinosaurs: Implications for cranial strength and feeding mechanics. Acta Palaeontologica Polonica 51 (3): 435–454. Tyrannosaurid theropods display several unusual adaptations of the skulls and teeth. Their nasals are fused and vaulted, suggesting that these elements braced the cranium against high feeding forces. Exceptionally high strengths of maxillary teeth in Tyrannosaurus rex indicate that it could exert relatively greater feeding forces than other tyrannosaurids. Areas and second moments of area of the nasals, calculated from CT cross−sections, show higher nasal strengths for large tyrannosaurids than for Allosaurus fragilis. Cross−sectional geometry of theropod crania reveals high second moments of area in tyrannosaurids, with resulting high strengths in bending and torsion, when compared with the crania of similarly sized theropods. In tyrannosaurids trends of strength increase are positively allomeric and have similar allometric expo− nents, indicating correlated progression towards unusually high strengths of the feeding apparatus. Fused, arched nasals and broad crania of tyrannosaurids are consistent with deep bites that impacted bone and powerful lateral movements of the head for dismembering prey. Key words: Theropoda, Carnosauria, Tyrannosauridae, biomechanics, feeding mechanics, computer modeling, com− puted tomography.

After the site was mapped in 2001, these two ichnotaxa were considered synonyms of Eubrontes and Anomoepus, respectively, the latter designation being the first identification of this ichnogenus in China. The assemblage indicates a typical Jurassic ichnofauna. The present study reinvestigates the site in the light of the purported new ichnospecies Chuanchengpus shenglingensis that was introduced in 2012. After re- evaluation of the morphological and extramorphological features, C. -

v^ Official Journal of the Biology Unit of the American Topical Association 10 Vol. 40(4) DINOSAURS ON STAMPS by Michael K. Brett-Surman Ph.D. Dinosaurs are the most popular animals of all time, and the most misunderstood. Dinosaurs did not fly in the air and did not live in the oceans, nor on lake bottoms. Not all large "prehistoric monsters" are dinosaurs. The most famous NON-dinosaurs are plesiosaurs, moso- saurs, pelycosaurs, pterodactyls and ichthyosaurs. Any name ending in 'saurus' is not automatically a dinosaur, for' example, Mastodonto- saurus is neither a mastodon nor a dinosaur - it is an amphibian! Dinosaurs are defined by a combination of skeletal features that cannot readily be seen when the animal is fully restored in a flesh reconstruction. Because of the confusion, this compilation is offered as a checklist for the collector. This topical list compiles all the dinosaurs on stamps where the actual bones are pictured or whole restorations are used. It excludes footprints (as used in the Lesotho stamps), cartoons (as in the 1984 issue from Gambia), silhouettes (Ascension Island # 305) and unoffi- cial issues such as the famous Sinclair Dinosaur stamps. The name "Brontosaurus", which appears on many stamps, is used with quotation marks to denote it as a popular name in contrast to its correct scientific name, Apatosaurus. For those interested in a detailed encyclopedic work about all fossils on stamps, the reader is referred to the forthcoming book, 'Paleontology - a Guide to the Postal Materials Depicting Prehistoric Lifeforms' by Fran Adams et. al. The best book currently in print is a book titled 'Dinosaur Stamps of the World' by Baldwin & Halstead. -

It differs from other oviraptorids in the skull having a well-developed crest, the anterior margin of which is nearly vertical, and the dorsal margin of the skull and the anterior margin of the crest form nearly 90°; the nasal process of the premaxilla being less exposed on the dorsal surface of the skull than those in other known oviraptorids; the length of the frontal being approximately one fourth that of the parietal along the midline of the skull. Phylogenetic analysis shows that Nemegtia barsboldi is more closely related to Citipati osmolskae than to any other oviraptorosaurs.

NUMBER 2I8I JUNE 4, I964 Relationships of the Saurischian Dinosaurs BY EDWIN H. COLBERT1 INTRODUCTION The word "Dinosauria" was coined by Sir Richard Owen in 1842 as a designation for various genera and species of extinct reptiles, the fossil bones of which were then being discovered and described in Europe. For many years this term persisted as the name for one order of reptiles and thus became well intrenched within the literature of paleontology. In- deed, since this name was associated with fossil remains that are frequently of large dimensions and spectacular shape and therefore of considerable interest to the general public, it in time became Anglicized, to take its proper place as a common noun in the English language. Almost every- body in the world is today more or less familiar with dinosaurs. As long ago as 1888, H. G. Seeley recognized the fact that the dino- saurs are not contained within a single reptilian order, but rather are quite clearly members of two distinct orders, each of which can be de- fined on the basis of many osteological characters. The structure of the pelvis is particularly useful in the separation of the two dinosaurian orders, and consequently Seeley named these two major taxonomic categories the Saurischia and the Ornithischia. This astute observation by Seeley was not readily accepted, so that for many years following the publication of his original paper proposing the basic dichotomy of the dinosaurs the 1 Chairman and Curator, Department ofVertebrate Paleontology, the American Museum of Natural History. -
