| Nesodactylus hesperius Colbert, 1969 |
Nesodactylus (meaning "island finger") was a genus of rhamphorhynchoid pterosaur from the Oxfordian-age Upper Jurassic Jagua Formation of Pinar del Rio, Cuba. It is based on AMNH 2000, a partial skeleton including a skull fragment, numerous vertebrae from all parts of the spine and tail, ossified tendons on the tail, the pectoral girdle and deeply keeled sternum, arms and partial hands, part of the pelvis, parts of both femorae, partial metatarsals, and ribs. This disarticulated but associated specimen was prepared from limestone with acid.
Its remains were collected but not prepared by Barnum Brown in the 1910s, from rocks better known for their fossils of marine life. Ned Colbert, who described it, found it to have had more robust limbs and longer legs than related Rhamphorhynchus, although of a similar size and overall anatomy. He classified it as a rhamphorhynchid.[1] It is the same animal as James A. Jensen and John Ostrom's Nesodon (1977).[2] Although there is little overlapping material with contemporaneous Cacibupteryx, the two are clearly different based on details of the elbow and quadrate.[3] At least one recent review suggests it was a rhamphorhynchid,[4] while another does not classify it.[5]
