''Sinraptor'' is a genus of Metriacanthosauridae, metriacanthosaurid theropod dinosaur from the Late Jurassic. The name ''Sinraptor'' comes from the Latin language, Latin prefix "Sino", meaning Chinese, and "raptor" meaning robber. The specific name ''dongi'' honours Dong Zhiming. Despite its name, ''Sinraptor'' is not related to dromaeosaurids (often nicknamed "raptors") like ''Velociraptor''. Instead, it was a Carnosauria, carnosaur distantly related to ''Allosaurus''. ''Sinraptor'' and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. ''Sinraptor'' still remains the best-known member of the Family (biology), family Metriacanthosauridae, with some older sources even using the name "Sinraptoridae" for the family. Discovery The holotype specimen of ''Sinraptor'' was uncovered from the Shishugou Formation during a joint Chinese/Canadian expedition to the northwestern Chinese desert in 1987, and described by Philip J. Currie and Zhao Xij ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow.
