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).
Stephen L. Brusatte
Brusatte has discovered more than a dozen new species of vertebrate fossils. His breakthrough in the study of dinosaur fossils was while at the University of Chicago with Paul Sereno. Having discovered the skull, jaw and neck fossils of a 95-million-year-old theropod in the Elrhaz Formation of Niger in 1997, Sereno was looking for a competent student to analyse it. Brusatte took the opportunity in 2004, completed the project in 2005, and published his findings in 2007 with Sereno. The animal was found to be a new species of "Carcharodontosaurus", which they named "C. iguidensis". He estimated that the complete skull would be more than five feet long, one of the biggest skulls of a known carnivorous dinosaur. This was followed by the description of another new theropod from the Elrhaz Formation in January 2008, "Kryptops palaios". Another significant discovery was from China in 2014. Alongside Chinese paleontologist Lü Junchang and others, Brusatte described a 66-million-year-old dinosaur, "Qianzhousaurus sinensis", which was closely related to the famous "T. rex". Due to its long snout, it was given the nickname "Pinocchio rex".
