来自印度尼西亚，爪哇，Cikalong 的真品巨齿鲨牙

高质量的巨齿鲨牙，尖端良好，具有清晰的锯齿和牙釉质，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭形鲨类，生活在大约2300万至360万年前（中新世早期至上新世）期间。它曾被认为属于灯笼鲨科并与大白鲨（Carcharodon carcharias）密切相关。然而，如今它被归入已灭绝的 Otodontidae 科，该科在早白垩纪便与大白鲨分道扬镳。

尽管被公认是有史以来最大、最强大的掠食者之一，巨齿鲨的化石证据仅有零散残迹，因此其外形和最大体型仍不确定。科学家对其更像大白鲨的矶岸版本、鲸鲨（Rhincodon typus）、护鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等，存在分歧。最近的估算在误差范围最小的情况下，最大体长可达约20.3米（67英尺），体重可达约103公吨（114短吨）。

长度 13,1 cm

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good tip, serrations , and enamel, 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon), meaning "big tooth", is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Pliocene epochs. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias). However, it is now classified into the extinct family Otodontidae, which diverged from the great white shark during the Early Cretaceous.

While regarded as one of the largest and most powerful predators to have ever lived, the megalodon is only known from fragmentary remains, and its appearance and maximum size are uncertain. Scientists differ on whether it would have more closely resembled a stockier version of the great white shark, the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) or the sand tiger shark (Carcharias taurus). The most recent estimate with the least error range suggests a maximum length estimate up to 20.3 meters (67 ft),  weighs up to 103 metric tons (114 short tons)
