This fossil has been restored using a sandblasting process. A plaque made of the same material is glued to the back of the fossil for reinforcement. 100% authentic, no stains.

Sandblasting, as its name indicates, involves using sand to blast fossils! Its operating principle is to mimic the desert wind blowing grains of sand, allowing rocks to naturally weather and expose the fossilized body! Sandblasting artificially accelerates this aging process! The sandblasting process involves creating pressurized air through an air pump. Depending on the hardness of the surrounding fossil rock, the air pressure is then adjusted to control the amount of sand produced. The fossil to be repaired is placed into the container holding the sand, with sand particles blown into the nozzle through the connecting pipe, and then the restorer can begin work by controlling the power and speed of the blasting, as well as local blasting.

Keichousaurus is an extinct genus of marine reptiles from the family Pachypleurosauridae. It lived during the Middle Triassic (Ladinian), approximately between 242 and 237 million years ago.
This aquatic animal is nowadays mostly found fossilized in China, particularly in the Guizhou province.
