Anhanguerid

Postcranial skeleton

In adult anhanguerids, the sacrum develops a supraneural plate above its neural spines. The tails of anhanguerids are poorly known, though they appear to be composed of at least eleven short vertebrae, and become relatively circular in cross section toward the end of the series. Like the related istiodactylids, the slender femora of anhanguerids have femoral heads that project almost in line with the femoral shaft, but seem to lack prominent processes that anchor their hindlimb muscles. Anhanguerids shinbones (or tibiae) are similarly developed and of equal length to the femora. Although the feet in anhanguerids are poorly known, they seem to be relatively small and gracile, with undeveloped claws and a hook-like fifth metatarsal.
