A new large theropod, Orkoraptor burkei nov. gen. et nov. sp., from the Upper Cretaceous (Maastrichtian) Pari Aike Formation of southern Patagonia is based on a postorbital, quadratojugal, coronoid?, several teeth, an atlantal intercentrum and neurapophysis, two caudal vertebrae, and the proximal half of tibia. This new theropod exhibits characteristics of maniraptorans (i.e., coelurosaurians more derived than tyra ... Read more »

Dinosauriform and dinosaurian remains are rare from the Late Triassic Dockum Group of
Texas. Using a synapomorphy-based approach, we evaluate new remains and previously reported remains assigned to Dinosauria from the Post Quarry (Garza County, Texas) and find that that the assemblage contains a non-dinosaur dinosauriform, an early saurischian, and a coelophysoid theropod. A partially associated skeleton of a di ... Read more »

The dinosaur fauna of the palynologically dated lower Berriasian Skyttegård Member of the Rabekke Formation on the Baltic island of Bornholm, Denmark, is represented by isolated tooth crowns. The assemblage is restricted to small maniraptoran theropods, assigned to the
Dromaeosauridae incertae sedis and Maniraptora incertae sedis. The dromaeosaurid teeth are characterized by their labiolingually compressed and d ... Read more »

The first protorosaur from the Middle Triassic of China, Dinocephalosaurus orientalis Li is known from two specimens: the holotype (an isolated skull in association with the first three cervical vertebrae), and a referred specimen (an almost complete, associated and partially articulated specimen lacking the tail). This material is here described in detail. A complete and amended diagnosis is given for the genus an ... Read more »
