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).
History of Plymouth
The earliest human remains in the Plymouth area are from a number of caves around Plymouth Sound. The 'bone caves', located at Cattedown, Oreston, Turnchapel and Stonehouse, contain extensive Upper Palaeolithic deposits, including those of "Homo sapiens", some of the earliest such evidence in England. A reindeer bone from one of the Cattedown caves is dated 15,125 ± 390 years B.P. There is no public access to the caves, and they are not easily locatable or visitable. However their archaeological importance is very great, owing to both the geographical location of the Cattedown discovery, in a European context, and to the quantitative and qualitative nature and physical disposition of the human remains; this is one of the most important discoveries for the early history of anatomically modern humans in Europe. There is currently no evidence of "Homo neanderthalensis" having been found in caves at Cattedown, Oreston, Stonehouse or Mount Batten (Turnchapel).
