Caption

Fossil shark teeth. Fossilised teeth from Striatolamia macrota, an ancient shark that lived during the Eocene period, 55 to 40 million years ago. This species is an ancestor of the modern sand shark. 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. Teeth are preserved because they are made of a bone-like enamel-coated substance. Found at Blackheath Beds, Abbey Wood, Kent, UK.
