来自印尼，爪哇，Cikalong 的正品巨齿鲨牙

优质巨齿鲨牙，尖端完好，带齿痕和牙釉质

巨齿鲨（Carcharocles megalodon，发音 /ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，约在始新世至上新世阶段的约2300万至360万年前生活过。它曾被认为属于真鲨科（Lamnidae）并与大白鲨（Carcharodon carcharias）相近，但现在被归入已灭绝的 Otodontidae 家族，分支与大白鲨在早白垩纪时分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的化石仅有零散残件，其外形和最大体型尚存不确定。科学家对于它更像是大白鲨的较结实版本、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间有不同意见。最近一次对误差范围较小的估计显示，其最大体长可达约 20.3 米（67 英尺），体重可达约 103 公吨（114 短吨）。

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)
