shark teeth: Carcharodon megalodon - Miocene (USA)

shark tooth:

"Carcharodon" megalodon

Miocene, South Carolina, USA

The species was described by Agassiz in 1835 under the extinct genus Otodus.

Today, the scientific name of this shark is:

Otodus (Megaselachus) megalodon,

because it is known that this shark with large triangular teeth is a lineage distinct from that of the modern great white shark Carcharodon carcharias, which also has large triangular teeth adapted to a similar diet (particularly large mammals).

The megalodon lived for 20 million years, from the Early Miocene (-23 Ma) to the Pliocene (-2.5 Ma), in warm waters.

"Meg" teeth are found all over the planet: Europe, Africa, America, Asia, and Oceania.
