Marasuchus
''Marasuchus'' is a genus of dinosaur-like ornithodiran from the middle Triassic (Ladinian age, about 230 million years ago) Chañares Formation of Argentina. It was a small predator only 40 cm long.〔http://www.palaeocritti.com/by-group/dinosauriformes/marasuchus〕
The species ''Marasuchus lilloensis'' was originally described as a second species of ''Lagosuchus'', ''L. lilloensis''. However, in a restudy of ''Lagosuchus'' by Sereno and Arcucci (1994), the authors concluded that the original (type) specimen was too poorly preserved to allow any further specimens to be assigned to the genus. They also noted that the ''L. lilloensis'' specimen had limb proportions different from the type species. On this basis, they assigned ''L. lilloensis'' to a new genus, ''Marasuchus''.〔Sereno, Paul C. and Arcucci, Andrea B. (1994). "Dinosaurian precursors from the Middle Triassic of Argentina: ''Marasuchus lilloensis gen. nov.''" ''Journal of Vertebrate Paleontology'' 14: 53-73 Chicago, IL (Abstract )〕
