base notes	DOTTED at 40% up in Sinemurian ""because the Dawan dinosaur Scelidosaurus is known from Sinemurian marine strata in the United Kingdom."" ""The Dawan begins with the FAD of the theropod dinosaur Megapnosaurus (""Syntarsus"") (known from Arizona and southern Africa with certainty, and less certainly from China and Europe)""; although it was introduced (Lucas, 1996) ""as the time equivalent to the vertebrate fossil assemblage of the Lufeng Formation in southern China."" (Lucas, 2009). Megapnosaurus (Greek for ""big dead lizard""), formerly called Syntarsus and related to Coelophysis of late Triassic, was about 2m long ""By the standards of the early Jurassic period, Megapnosaurus was huge"" -- Megapnosaurus details and image: http://dinosaurs.about.com/od/carnivorousdinosaurs/p/megapnosaurus.htm .				comp notes
