Shark Teeth

Sharks continually replace their teeth throughout their lives, shedding many into their surroundings. Some of these teeth become buried in sediment and, under suitable conditions, are preserved as fossils.

Unlike their durable teeth, shark skeletons are made mainly of cartilage, which rarely survives fossilisation. Fossil teeth therefore provide much of the evidence scientists use to study ancient sharks. Their shape, size and cutting edges can offer clues about feeding habits and evolutionary relationships.

Megalodon, Great White and Otodus teeth reveal different features of these ocean predators. When choosing a specimen, look at its crown, root and any preserved serrations or smaller side points. Colour and surface appearance can vary with the conditions in which the tooth was preserved.
