A nice Keichousaurus hui (K. hui) marine reptile fossil. This specimen offers some very good bone detail and is 7.63 inches in length (longer if it were stretched out). Also included on the slab is a coprolite (fossil dung) containing some bones. The matrix has a couple of repairs.
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.
