来自印度尼西亚爪哇岛 Cikalong 的真实巨齿鲨牙齿

高质量巨齿鲨牙，带有良好的尖端、锯齿和珀质/牙釉质完整。

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，约生活在二千三百万年至三百六十万年前的中新世早期至中新世晚期。它曾被认为属于露齿鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。但现今被归入已灭绝的 Otodontidae 科，该科在早白垩纪时就已与大白鲨分化。

尽管被视为史上最大、最强大的掠食者之一，巨齿鲨的化石多为碎片，其外形和最大体长仍不确定。科学家对它更接近于大白鲨的体型、抹香鲸、灯笼鲨（温暖鲨 Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等哪个形态存在分歧。最新且误差范围最小的估计显示，最大体长可达约20.3米，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)
