Megalodon - Fossil tooth - 11 cm

Huge Megalodon tooth. Completely natural
Unfortunately, it was damaged during the excavation, but it remains a very valuable tooth, enormous and with a beautiful shape and color. Discovered on the island of Java. A small restoration is visible in the root zone.
Otodus megalodon (the species name, megalodon, derives from Greek and means "great tooth"), commonly known as megalodon or megalodonte, is an extinct species of giant shark that lived from the Early Miocene to the Early Pliocene, about 23–3.6 million years ago (Aquitanean–Zanclean), whose large fossil teeth demonstrate that it had a cosmopolitan distribution. In the past it was thought that O. megalodon was a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct family Otodontidae, a family that separated 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.
