And they had lots of little arms that looked like a blossom. These are about 250,000,000 years old. Fossil Ammonite from near San Ysidro, New Mexico. Ammonites lived in the oceans a long time ago. This one is about 55,000,000 years old.
Ammonites look like snails but they are related to squids.
They had long tentacles to catch their food, and they floated around in the water rather than crawled on rocks and seaweed and coral like sea snails do. Fossil Dinosaur Bone from near San Ysidro, New Mexico. These are small pieces of dinosaur bone. They are about 145,000,000 years old. If the Paleontologist looks harder, she or he might find more of the fossil bones, in better shape, and be able to excavate the bones and take them to a museum, and study them.
