    • Abstract Detailed description of the Middle Permian Russian caseid Ennatosaurus tecton shows that three autapomorphies distinguish it from other caseids: a broad anterior ramus of the jugal, a large contribution of the frontal to the dorsal orbital margin, and a relatively narrow parasphenoid body. Phylogenetic analysis of Caseidae yields a single most parsimonious tree and its topology posits Ennatosaurus tecton as the sister taxon to the clade of the North American caseids Angelosaurus dolani… CONTINUE READING
