Eocursor, new basal ornithischian

Butler Richard J.,Smith Roger M. H., and Norman David B., in press. A primitive 
ornithischian dinosaur from the Late Triassic of South Africa, and the early 
evolution and diversification of Ornithischia, Proc. R. Soc. B, 1-6

Nice specimen, look somewhat like a "fabrosaurid" with large hands, there is a 
cladogram of Ornithischian with basalmost Heterodontosaurids (except 
Pisanosaurus), but no mention of putative basal ornithischian like Sacisaurus, 
Silesaurus and possible related form (Technosaurus, Pseudolagosuchus, 
Eucoelophysis, ?Bromsgroveia, Spondylosoma, ?Caseosaurus).
Some feature, like a large grasping hand with well developed extensor pit on 
metacarpals are probably plesiomorphic for Dinosauria, being present in 
Eocursor and Heterodontosaurids.
