Discussion

A. heterodontus is twice the size of A. pumilio (Rieppel, 2000). Anarosaurus is Similar to 'Psilotrachelosaurus' but differs in lacking pachyostic dorsal ribs and the humeri are larger in relation to the size of the body (Rieppel, 1993). Rieppel (1993) also notes how the obturator foramen on the posterior margin of the pubi remain open.
