What is keel stone?

The keel stone is an animal fossil. The cause is that after the animal is buried in the soil, the organic matter in the bone is dissolved and lost by the groundwater, and the minerals such as calcium in the water are precipitated. After long-term replacement, the essence of the bone completely changes, but the bone remains. The original form becomes a fossil. Animal fossils are buried in a layer of gray-yellow sandy soil, which is dominated by birds and rodents, and has certain scientific value.
