In this category you can find fossil teeth of Carcharocles Megalodon ancestors.
According to the current status the known ancestors were: Carcharocles Auriculatus -> Carcharocles Angustidens -> Carcharocles Chubutensis - > Carcharocles Megalodon
Carcharocles Auriculatus lived in the Middle to Late Eocene, 28 - 45 million years ago and had a length of about up to 9 meters. The teeth have large, serrated cusps laterally that are coarsely serrated and a pronounced bulge on the lingual side of the root. The tooth of an adult C. Auriculatus is 8 - 10 cm long.
The Carcharocles Angustidens lived in the Early to Late Oligocene, 25 - 35 million years ago and reached a maximum length of 11 meters. The teeth of C. Angustidens are similar to those of C. Auriculatus, but have a much finer serration. The lateral cusps are triangular and serrated and the root is rectangular to pointed. The tooth of an adult C. Angustidens is 9 - 10 cm long.
Carcharocles Chubutensis lived in the Early to Earliest Miocene, 15 - 23 million years ago and reached a length of up to 12 meters. It is considered the direct ancestor of the prehistoric giant C. Megalodon. The teeth show very reduced cusps with a clearly reduced notch and have a very fine serration. The tooth crown is broad and the tooth root has only a small bulge on the lingual side.The tooth of an adult C. Chubutensis is 9 - 13 cm long.
