An important parameter in studying the macroevolutionary history of a clade is variation its body size. However, analysis this archosauromorphs has been restricted to Archosauria, and disparity size not exhaustively explored. In present work, we study more than 400 known Permian–Early Jurassic archosauromorph species context their early evolutionary radiation. We analysed over time relationship between palaeolatitudinal distribution species. From these analyses, it was found that increased...
The Jurassic record of South American theropods is scarce, being represented by only seven nominal species. Four these species (Eoabelisaurus mefi, Asfaltovenator vialidadi, Condorraptor currumili and Piatnitzkysaurus floresi) have been found in Toarcian-aged localities the Cañadón Asfalto Formation (Chubut Province, Argentina) and, as a result, this unit has highest known diversity on continent. A dentary with teeth situ (MPEF-PV 6775) was close to base formation differs from other...
Abstract Piatnitzkysaurus floresi is a theropod dinosaur from the Cañadón Asfalto Formation (Chubut Province, Argentina) and one of few Early Jurassic tetanurans known worldwide. This species two specimens plays key role in our understanding early evolution tetanuran theropods. Nevertheless, published information about its postcranium limited to original description 1980s drawings views. Here, we redescribe detail appendicular skeleton Piatnitzkaysaurus integrate new into phylogenetic...
