is a genus of rynchosaur
that lived in England during the early part of
the Mid Triassic. The genus was born out of the decision to move a
species of the Rhynchosaurus
genus on the basis of differences from
the type species that by todays taxonomic standards would warrant a new
genus as opposed to an additional species. Like other rhynchosaurs,
Fodonyx would have been a quadrupedal archosaur
that used its chisel
like incisor teeth to eat plants.
One of the specimens moved to Fodonyx, a skull, has now been found to represent a genus in its own right, and was used to establish the genus Bentonyx.
