印尼 印尼爪哇，Cikalong 的正品 Carcharocles megalodon 牙齿

高质量的巨齿鲨牙，尖端完好，锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨科动物，生活在大约2300万年前至360万年前（早中新世至上新世），从早始新世到上新世。它曾被认为属于狼鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）有密切关系。然而，现今被归入已灭绝的 Otodontidae 家族，该科在早白垩纪就已从大白鲨分化出来。

尽管被视为有史以来最大、最强大的掠食者之一，但巨齿鲨仅有碎片状遗骸可供研究，其外观和最大体长仍不确定。科学家对于它更像大白鲨的矮胖版本、抹香鲸（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间存在分歧。最近一次误差范围最小的估计表明其最大长度可达约20.3米（67英尺），体重可达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)
