Pterodactylus Suevicus
''Cycnorhamphus'' (meaning "swan beak") is a genus of Gallodactylidae, gallodactylid ctenochasmatoidea, ctenochasmatoid pterosaur from the Late Jurassic period of France and Germany, about 152 million years ago. It is probably synonymous with the genus ''Gallodactylus''. History In 1855, a fossil in a plate of shale from the Kimmeridgian, found near Nusplingen in Württemberg, holotype GPIT "Orig. Quenstedt 1855, Taf. 1" or GPIT 80, was named ''Pterodactylus Suevicus'' by Friedrich August Quenstedt. The specific name refers to the tribal area of Suevia. Quenstedt had earlier mentioned the find in a letter to Professor Heinrich Georg Bronn, which was published in 1854. In it he used the name ''Pterodactylus Württembergicus''. In 1855 and 1858, Christian Erich Hermann von Meyer adopted this older species name but it would be forgotten afterwards. The publication in 1854 was not meant to be a nomenclatural act. According to Peter Wellnhofer, ''Pterodactylus württembergicus'' should ... [...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. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
