Ludodactylus sibbicki

The specific name of this large pterosaur honors famous paleoartist John Sibbick. Ludodactylus was a crested ornithocheirid from the Early Cretaceous of Brazil, known from a single nearly complete skull missing the distal end of the crest. It was preserved with a leaf between its mandibles thus its nickname, the "tree-biter" and on the same slab that contain the fossils of the fish Dastilbe. The generic name refered to the fact that the animal resembles the inacurrate popular depiction of toy Pteranodon with teeth (Pteranodon was crested but toothless). It may turn out that Ludactylus is the same animal than Brasileodactylus.
