Pteranodon
"Pteranodon" was the first pterosaur found outside of Europe. Its fossils first were found by Othniel Charles Marsh in 1870, in the Late Cretaceous Smoky Hill Chalk deposits of western Kansas. These chalk beds were deposited at the bottom of what was once the Western Interior Seaway, a large shallow sea over what now is the midsection of the North American continent. These first specimens, YPM 1160 and YPM 1161, consisted of partial wing bones, as well as a tooth from the prehistoric fish "Xiphactinus", which Marsh mistakenly believed to belong to this new pterosaur (all known pterosaurs up to that point had teeth). In 1871, Marsh named the find ""Pterodactylus oweni"", assigning it to the well-known (but much smaller) European genus "Pterodactylus". Marsh also collected more wing bones of the large pterosaur in 1871. Realizing that the name he had chosen had already been used for Harry Seeley's European pterosaur species "Pterodactylus oweni" in 1864, Marsh re-named his giant North American pterosaur Pterodactylus occidentalis, meaning "Western wing finger," in his 1872 description of the new specimen. He also named two additional species, based on size differences: Pterodactylus ingens (the largest specimen so far), and Pterodactylus velox (the smallest).
Timeline of pterosaur research
Pterosaur paleontology continues to progress into the 21st century. In fact, according to David Hone the early 21st century has seen more progress in pterosaur paleontology than in "the preceding two centuries" combined. He compared this transformative period in pterosaur paleontology to the Dinosaur Renaissance of the 1970s. He also observed that roughly one-third of known pterosaurs were discovered during this brief interval. One of the most notable of these was "Darwinopterus", whose body resembled the more primitive long-tailed "rhamphorynchoids", while its skull resembled those of the more advanced short-tailed pterodactyloids. These traits establish the species as an important transitional form, documenting one of the most important phases of pterosaur evolution. Another important new species is "Faxinalipterus minima", which might well be the world's oldest pterosaur. The first confirmed pterosaur eggs were also reported from China during the early 21st century.
