Ludodactylus (meaning "play finger") is a genus of anhanguerid pterodactyloid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Crato Formation of the Araripe Basin in Ceará, Brazil. The type and only species is L. sibbicki. The generic name Ludodactylus refers to the fact that the animal had the combination of teeth and a Pteranodon-like head crest, similar to many toy pterosaurs, and no such creature was known to exist until the discovery of Ludodactylus. However, Ludodactylus is not the only pterosaur now known to possess these features, its very close relative Ca
Ludodactylus (meaning "play finger") is a genus of anhanguerid pterodactyloid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Crato Formation of the Araripe Basin in Ceará, Brazil. The type and only species is L. sibbicki. The generic name Ludodactylus refers to the fact that the animal had the combination of teeth and a Pteranodon-like head crest, similar to many toy pterosaurs, and no such creature was known to exist until the discovery of Ludodactylus. However, Ludodactylus is not the only pterosaur now known to possess these features, its very close relative Caulkicephalus is another example.
==Etymology== The genus was named by Eberhard Frey et al. in 2003 and contains one known species, Ludodactylus sibbicki. The name is derived from Latin ludus, "play" and Greek daktylos, "finger". Ludus refers to the fact, long lamented by paleontologists, that many toy pterosaurs combined teeth with a Pteranodon-like head crest, while no such creature was known to exist — however, Ludodactylus shows exactly this combination of features. "Dactylus", in reference to the characteristic long wing finger, has been a common element in the names of pterosaurs, since the first known genus was named Pterodactylus. The specific name "sibbicki" is an homage to the paleoartist John Sibbick.
