Summary
[edit]DescriptionSinosauropteryx prima feathered dinosaur (Yixian Formation, Lower Cretaceous; Sihetun Quarry, Liaoning Province, northeastern China) (15189586090).jpg |
Sinosauropteryx prima Ji & Ji, 1996 feathered theropod dinosaur (holotype, part) from the Cretaceous of China (NGMC 2123, National Geological Museum of China, Beijing, China). This is Sinosauropteryx prima, the first ever discovered & most famous feathered dinosaur. A relative abundance of feathered dinosaurs and early birds has been found in the Jehol Group of northeastern China. The most famous & most frequently illustrated Sinosauropteryx specimen is the holotype, which consists of part & counterpart slabs (each is housed at separate institutions in China). The dark fringe running down the neck, back & tail represents feathers. This animal was a relatively small theropod dinosaur. Classification: Animalia, Chordata, Vertebrata, Dinosauria, Saurischia, Theropoda, Compsognathidae Stratigraphy: lower Yixian Formation, Yehol Group, near-lowermost Cretaceous Locality: Sihetun Quarry, Shangyuan, Beipiao City, Liaoning Province, northeastern China By the way, this is my photo of the actual holotype slab, which was on temporary display at Yale University's Peabody Museum of Natural History (New Haven, Connecticut, USA) in 1999. Theropod were small to large, bipedal dinosaurs. Almost all known members of the group were carnivorous (predators and/or scavengers). They represent the ancestral group to the birds, and some theropods are known to have had feathers. Some of the most well known dinosaurs to the general public are theropods, such as Tyrannosaurus, Allosaurus, and Spinosaurus. |
