Figure 18. Stratigraphical comparisons between reptiles found in the Tytherington Triassic fissures and the same or closely related genera from normal bedded sequences worldwide. Data from Shubin & Sues (1991), Wu (1994), Shubin, Olsen & Sues (1994), Luo & Wu (1994), Sues, Clark & Jenkins (1994), Benton (1994), Sues & Reisz (1995), Sues, Shubin & Olsen (1994), Renesto (1995), Duffin (1995), Lucas (1998, 1999), Irmis (2004) and Säila (2005). Ch is China, Eu is Europe, NAm is North America and SAfr South Africa. The Tytherington coelurosaur is most similar to Megapnosaurus which Lucas & Tanner (2006) regard as first appearing in, and defining the beginning of, the Dawan LVF (equivalent to the Sinemurian), but which Bristowe & Raath (2004) regard as congeneric with Coelophysis. In addition to the data displayed, Bonaparte & Sues (2006) have recently described Clevosaurus from the Caturitta Formation (?Carnian–Norian) of Rio do Sul, Brazil.
