In 1907, paleontologist J. H. Lees described this fossil, an ilium (part of the hip) from the Popo Agie Formation, and identified it as that of the phytosaur Paleorhinus bransoni.[2] In 1915, paleontologist M. G. Mehl named Poposaurus based on more complete material from the Popo Agie Formation, including vertebrae, hips, and limb bones. He cited the holotype as [Walker Museum] 602, but in fact the holotype is UR 357. Mehl concluded that the ilium described by Lees, UR 358, also belonged to Poposaurus. He did not classify Poposaurus as a phytosaur because the shape of its ilium was different and it had more sacral vertebrae fused to the hip. Mehl made comparisons between Poposaurus and the earlier named Dolichobrachium, also from the Triassic of Wyoming. Dolichobrachium was only known from some teeth, a humerus, and part of the pectoral girdle, so Mehl suggested that the Poposaurus and Dolichobrachium material could belong to the same animal. Mehl noted similarities between Poposaurus and theropod dinosaurs, including its hollow leg bones and deep hip socket, but did not consider it a dinosaur because each sacral vertebra supported only one rib (theropods usually have multiple ribs projecting from each sacral vertebra).[3] In the following years, Poposaurus was assigned to many different groups of reptiles. Hungarian paleontologist Franz Nopcsa classified it as an ornithischian dinosaur in 1921, identifying similarities with iguanodonts and camptosaurs. In 1928, Nopcsa placed it in a new family called Poposauridae and a new suborder called Poposauroidea. To Nopsca, Poposauroidea was one of three suborders that made up the order Ornithopoda. Over the following years, many paleontologists supported this classification. For example, German paleontologist Oskar Kuhn classified Poposaurus in its own suborder of ornithischians, which he called Poposauria. In 1930, American paleontologist Oliver Perry Hay placed Poposaurus in Anchisauridae, a family of sauropodomorph dinosaurs. German paleontologist Friedrich von Huene considered it a very early stegosaur in 1950.[4] In 1961, American paleontologist Edwin Harris Colbert gave an extensive description of the known material of Poposaurus and classified it as a theropod dinosaur. Colbert thought that Poposaurus could not have been a more primitive archosaur because it had hollow leg bones and complex vertebrae. He placed it in the Carnosauria, but because its ilium was distinct from all other archosaurs, Colbert placed Poposaurus in its own family, Poposauridae. In the same paper, Colbert described an ilium from the Dockum Group of Howard County, Texas, which he assigned to P. gracilis.[4] #edit #nationalistedit #nicoledollanganger #worldwar2 #History
