Description
Shark tooth fossil. Fossil of a tooth of an ancient shark (Lamna sp.). This shark was smaller than the giant sharks found in ancient seas. Sharks are predatory fish that first evolved in the Palaeozoic Era (245-570 million years ago). They now dominate present-day seas. Few fossilised remains of prehistoric sharks exist because their skeletons were formed of cartilage, a less durable material than bone. Shark teeth are made of a bone-like enamel-coated substance that is more readily fossilised. This specimen was found in Morocco.
