Description

Description: Phylum: Chordata Class: Sauropsida Family: Pachypleurosaur Order: Nothosauroidea Common Name: Marine Reptile Age: Triassic Location: China Description: Rectangular slab with finely detailed (full skeleton) fossil. Color is dark gray to black. Physical Characteristics: Keichousaurus is a genus of marine reptile in the pachypleurosaur family which went extinct at the close of the Triassic in the Triassic-Jurassic extinction event. The name derives from Kweichow (now Guizhou Province) in China where the first fossil specimen was discovered in 1957. They are among the most common sauropterygian fossils recovered and are often found as nearly complete, articulated skeletons, making them popular among collectors. Keichousaurus, and the pachypleurosaur family broadly, are sometimes classified within Nothosauroidea, but are otherwise listed as a separate, more primitive lineage within Sauropterygia. Family: Pachypleurosaur Kingdom: Animalia (Animals) Class: Sauropsida Order: Nothosauroidea Phylum: Chordata
