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).
Chaoyang, Liaoning
Liaoning, and in particular Chaoyang, has become the focus of great interest in the world of palaeontology. During the 1990s, many new, unique and fascinating fossils were discovered in this region. Some of the finds have completely revolutionised our ideas of dinosaurs and shed new light on the origin of birds. Chaoyang's fossils are in the Jiufotang Formation. These fossils include: Liaoxipterus, a genus of ctenochasmatid pterodactyloid pterosaur from the Lower Cretaceous; Microraptor, a feathered dinosaur; and several early birds such as Longipteryx Chaoyangensis, Sapeornis Yanornis and Shenzhouraptor, an early bird. Insects have also been found such as Dictyoptera, a fossilised cockroach and Hymenoptera, a fossil bee, which also date to the Lower Cretaceous period. A local trade in rare fossils has developed in the wake of the finds, with an estimated sixty vendors gathering in one area, called Ancient Street.
