Male Keichousaurus fossil, the animal is about 34 cm long (without bending). It is difficult to find fossils of this size in the white form. The general situation is dorsal type. The white wire is quartz wire. Fossils produced in this stratum are very rare, and because of the different mineralization of the stratum, the colors are different, so it will be different from the previous black slate, the bones will be white, very rare! Keichousaurus fossil always use the grinding method to clean, but this method will destroy the original fossil structure. If sandblasting is used, the fossil will be restored to perfection and it will be more taught to its original skeletal shape. This fossil has been cleaned very beautifully, and the bones are very distinct from the matrix. This fossil is attached with a transparent plastic frame, which makes the fossil display more beautiful! Keichousaurus (key-cho-saurus) 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.
