picture info	Stenopelix ''Stenopelix'' (meaning "narrow pelvis") is a genus of small marginocephalian dinosaur, possibly a basal ceratopsian, from the Early Cretaceous of Germany. It lived in the late Berriasian faunal stage, Stage of the Cretaceous period, approximately 140 myr ago.Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> The genus is based on a partial skeleton lacking the skull, and its classification is based on characteristics of the hips. Discovery and species In 1855, in a sandstone quarry near Bückeburg on the Harrl, a fossil was found of a small dinosaur. Most of its bones were in a poor condition and removed on preparation, leaving two sets of hollow impressions on the plate and counterplate. The two plates do not overlap completely. The hollows, serving as a natural mold, have since been used to produce several casts in gypsum and latex to facilitate the study of the specimen. It was origin ...

	Christian Erich Hermann Von Meyer Christian Erich Hermann von Meyer (3 September 1801 – 2 April 1869), known as Hermann von Meyer, was a German palaeontologist. He was awarded the 1858 Wollaston medal by the Geological Society of London. Life He was born at Frankfurt am Main. In 1832, Meyer issued a work entitled ''Palaeologica'', and in course of time he published a series of memoirs on various fossil organic remains: molluscs, crustaceans, fishes and higher vertebrata, including the Triassic predator ''Teratosaurus'', the earliest bird ''Archaeopteryx lithographica'' (1861), the pterosaur ''Rhamphorhynchus'', and the prosauropod dinosaur ''Plateosaurus''. In ''Palaeologica'', Meyer proposed a classification of fossil reptiles into four major groups based on their limbs: Saurians with Toes Similar to those of Living Species (e.g.''Teleosaurus'', ''Protorosaurus'', '' Streptospondylus'') Saurians with Limbs Similar to Heavy Land Mammals (''Iguanodon'', ''Megalosaurus'') Saurians with Limbs for Swimmin ...

	Marginocephalia Marginocephalia (/mär′jə-nō-sə-făl′ē-ən/ Latin: margin-head) is a clade of ornithischian dinosaurs that is characterized by a bony shelf or margin at the back of the skull. These fringes were likely used for display. There are two clades included in Marginocephalia: the thick-skulled Pachycephalosauria and the horned Ceratopsia. All members of Marginocephalia were primarily herbivores. They basally used gastroliths to aid in digestion of tough plant matter until they convergently evolved tooth batteries in Neoceratopsia (or "new Ceratopsia") and Pachycephalosauria. Marginocephalia first evolved in the Jurassic Period and became more common in the Cretaceous. They are basally small facultative quadrupeds while derived members of the group are large obligate quadrupeds. Primitive marginocephalians are found in Asia, but the group migrated upwards into North America. Pachycephalosaurs, or "thick-headed reptiles", have primitive features that include basally small sized bodi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	William Diller Matthew William Diller Matthew Royal Society, FRS (February 19, 1871 – September 24, 1930) was a vertebrate paleontologist who worked primarily on mammal fossils, although he also published a few early papers on mineralogy, petrological geology, one on botany, one on trilobites, and he described ''Tetraceratops insignis'', which was much later suggested to be the oldest known (Cisuralian, Early Permian) therapsid. Matthew was born in Saint John, New Brunswick, Saint John, New Brunswick, the son of George Frederic Matthew and Katherine (Diller) Matthew. His father was an amateur geologist and paleontologist who instilled his son with an abiding interest in the earth sciences. Matthew received an A.B. at the University of New Brunswick in 1889 and then earned his Ph.D. at Columbia University in 1894. Matthew was curator of the American Museum of Natural History from the mid-1890s to 1927, and director of the University of California Museum of Paleontology from 1927 to 1930. He was the fat ...

	1850s In Paleontology Year 185 ( CLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
