This happens 130 million years ago. There is an ocean in Colombia. An animal lives in the ocean. It is eight meters long. It has a long neck. The animal’s name is a plesiosaur.
The animal dies. Its body changes into a fossil. Scientists find the fossil in Colombia. There is no ocean in the place now.
Fossils of plesiosaurs are not only in Colombia. Scientists find them in other places, too. They find them in Australia, North America, northern Europe and Antarctica.
Difficult words: fossil (rock), scientist (clever person who is an expert in something).
