Keichousaurus fossil always use the grinding method to clean, but this method will destroy the original fossil structure. If sandblasting is used, the fossil has been cleaned to perfection and it will be more taught to its original skeletal shape. 

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.
