The Megalodon shark dominated the oceans of the world for over 20 million years. Reaching sizes upwards of 18m (59ft) in length, the largest Megalodon jaw reconstruction measures 3.3m (11ft) across and 2.7m (9ft) tall.

This specimen is a chunk of fossilized Megalodon poop. Scientifically known as coprolites, these fossils are important indicators of the prehistoric shark's territory and diet, and leave us clues about the wider food chain of the ancient ocean.

Both small and large specimens are available, along with complete showcase fossils below. Each specimen comes with a photo card that also contains authenticity information on the back.
