Fossil Generation - The Legend of the Stone Monster This book introduces the generation of fossils more intuitively. The book introduces that dinosaurs fell into the river and were eaten up by fish and shrimp. After many years, the small holes in the bones were filled with minerals in the water and turned into stones. I used to think that if it was buried in the soil, it would turn into a fossil, but I didn't expect that the fossil was easy to produce in the water in the early stage.
