An Unusual New Theropod with a Didactyl Manus from the Upper Cretaceous of Patagonia, Argentina

The diversity of saurischian dinosaurs is particularly high, especially in the late Cenomanian-early Turonian Huincul Formation, which has yielded specimens of rebacchisaurid and titanosaurian sauropods, and abelisaurid and carcharodonto...
متن کاملHigh Diversity, Low Disparity and Small Body Size in Plesiosaurs (Reptilia, Sauropterygia) from the Triassic–Jurassic Boundary
Invasion of the open ocean by tetrapods represents a major evolutionary transition that occurred independently in cetaceans, mosasauroids, chelonioids (sea turtles), ichthyosaurs and plesiosaurs. Plesiosaurian reptiles invaded pelagic ocean environments immediately following the Late Triassic extinctions. This diversification is recorded by three intensively-sampled European fossil faunas, span...

متن کاملLate Cretaceous Aquatic Plant World in Patagonia, Argentina
In this contribution, we describe latest Cretaceous aquatic plant communities from the La Colonia Formation, Patagonia, Argentina, based on their taxonomic components and paleoecological attributes. The La Colonia Formation is a geological unit deposited during a Maastrichtian-Danian transgressive episode of the South Atlantic Ocean. This event resulted in the deposition of a series of fine-gra...
متن کاملA new species of Liolaemus (Reptilia: Squamata) from southwestern Rio Negro province, northern Patagonia, Argentina
A new species of lizard of the genus Liolaemus from southwestern Rio Negro Province, central Patagonia is described. The new species is a member of the Liolaemus fitzingerii group, and molecular data show it as sister taxon of L. martorii, but it differs in size, squamation, coloration, and sexual dimorphism. Liolaemus casamiquelai sp. nov. is terrestrial, dwelling on loose sandy soil in a shru...
