Batrachomimus Pastosbonensis
''Batrachomimus'' is an extinct genus of neosuchian Crocodyliformes, crocodyliform known from the Late Jurassic Pastos Bons Formation of northeastern Brazil. It contains a single species, ''Batrachomimus pastosbonensis'', with the Specific name (zoology), specific name referring to the formation, which was first described and named by Felipe C. Montefeltro, Hans C. E. Larsson, Marco A. G. de França and Max C. Langer in 2013 in paleontology, 2013. It is known from a nearly complete skull, osteoderms and limb bones. ''Batrachomimus'' belongs to the family Paralligatoridae and predates all other members of the family and its immediate sister group, Eusuchia, by 30 million years. Description ''Batrachomimus'' is known from a single holotype skull known as LPRP/USP-0617, which preserves most of the skull and lower jaws except for the skull table, braincase, and the left Temple (anatomy), temporal region. The skull is about , giving an estimated total body length of about . ''Batrachom ... [...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.
