Tropeognathus. Species: T. mesembrinus, T. robustus.
Meaning of name: Keel jaw.
Brazil, Early Cretaceous.
Classification: Pterosauria, Pterodactyloidea, Ornithocheiroidea.
There is evidence that some pterosaurs had webbing between their fingers so I thought I would illustrate this on Tropeognathus as a possible candidate.
