Shark tooth with box

Shark teeth as fossils give us a direct link to a time long before humans existed, and tell stories of the sea's formidable predators. These fossils can be millions of years old and are often found in sedimentary layers that were once the seabed. Shark teeth are very hardy and preserve well because they consist of dentin, a type of tissue that is resistant to the ravages of time. Most fossil shark teeth sold today originate from extinct shark species such as Carcharocles megalodon or sand tiger shark. The size and shape of the teeth vary, which makes them extra interesting for collectors and researchers. As well as being popular as collectibles and jewellery, they provide insight into sharks' eating habits and evolution.
