Megalodon - Fossil tooth - 10 cm

Big Megalodon tooth. Completely natural, a very valuable 10 cm tooth, enormous and with a beautiful shape and color. Just reassembled one part near the root. Discovered on the island of Java.
Otodus megalodon (whose species name, megalodon, derives from Greek and means 'large tooth') is an extinct species of giant shark that lived from the early Miocene to the early Pliocene, approximately 23 to 3.6 million years ago (Aquitanian to Zanclean), with large fossil teeth indicating it had a cosmopolitan distribution. In the past, it was thought that O. megalodon belonged to the family Lamnidae and was a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct family Otodontidae, which diverged from the lineage of the great white shark during the Early Cretaceous.

Estimates of the megalodon's size vary depending on the method used, with maximum total length projections ranging from 14.2 to 20.3 meters.
