Type material of the type species of the classic theropod footprint genera Eubrontes, Anchisauripus, and Grallator (Early Jurassic, Hartford and Deerfield basins, Connecticut and Massachusetts,…
ABSTRACT The classic Early Jurassic age theropod footprints Eubrontes giganteus, Anchisauripus sillimani, and Grallator parallelus were established by Edward Hitchcock in 1836–1847 and are the type…

A quantitative methodology designed to provide defensible identifications of isolated teeth using Tyrannosaurus as a comparison taxon and results indicate that expanding the standard should facilitate the identification of numerous types of isolated theropod teeth.

This examination revealed that several putative systematic characters related to size and shape can be discerned from T. rex teeth, suggesting that useful dental characters may be more common within the Theropoda than has generally been presumed.
DENTAL MORPHOLOGY AND VARIATION IN MAJUNGASAURUS CRENATISSIMUS (THEROPODA: ABELISAURIDAE) FROM THE LATE CRETACEOUS OF MADAGASCAR

- 12 June 2007
Documentation of the intra-individual and intraspecific variation in Majungasaurus tooth anatomy provides a standard against which other abelisaurids can be compared and provides a suite of dental features that potentially can be used to assist in evaluation of the phylogenetic position of Majung asaurus among abelISaurids and Abelisauridae among theropods.
A Giant Sauropod Dinosaur from an Upper Cretaceous Mangrove Deposit in Egypt
We describe a giant titanosaurid sauropod dinosaur discovered in coastal deposits in the Upper Cretaceous Bahariya Formation of Egypt, a unit that has produced threeTyrannosaurus-sized theropods and…
A DEFINITIVE ABELISAURID THEROPOD DINOSAUR FROM THE EARLY LATE CRETACEOUS OF PATAGONIA
Abstract A nearly complete, well-preserved maxilla of an abelisaurid theropod from the early Late Cretaceous (middle Cenomanian-Turonian) Lower Member of the Bajo Barreal Formation of Chubut,…

An abelisaurid from the Late Cretaceous of Egypt: implications for theropod biogeography
It is reported on a shed theropod tooth from the Upper Cretaceous Duwi Formation of Egypt that constitutes defensible evidence of an abelisaurid from the post-Cenomanian Cret Jurassic of mainland Africa, and indicates that Abelisauridae was a diverse group in Africa during the CRETaceous.
