| 説明 | Colosteus sp. - fossil amphibian from the Pennsylvanian of Ohio, USA.The Linton Lagerstätte is a famous fossil deposit at the Diamond Coal Mine in far-eastern Ohio. It occurs in channel-filling, fissile cannel coal in the lower Upper Freeport Coal. The Upper Freeport is about 9 feet thick at this locality - it was the target for mining. The fissile cannel coal at the base of the Upper Freeport was waste rock and discarded in a large pile. Fossils include plants (palynomorph microfossils), invertebrates (principally conchostracans), and vertebrates (fish, amphibians, reptiles). The fossil seen here is a partial specimen of Colosteus, a stem-group amphibian. Notice that the body surface has well-developed scalation.Classification: Animalia, Chordata, Vertebrata, Tetrapodomorpha, Stegocephalia, ColosteidaeStratigraphy: lower Upper Freeport Coal, Allegheny Group, Middle PennsylvanianLocality: Diamond Coal Mine, Linton, far-eastern Jefferson County, far-eastern Ohio, USA-------------------See info. at:en.wikipedia.org/wiki/Colosteus |
