来自印尼爪哇岛 Cikalong 的正品巨齿鲨牙 

高质量的巨齿鲨牙，尖端良好、锯齿和琺质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已经灭绝的鲭鱼类鲨鱼，生活在约2300万年前至360万年前的始新世至中新世。它曾被认为属于鲭科，并与大白鲨（Carcharodon carcharias）有密切关系，但现在被归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪就已分离。

尽管被认为是有史以来最大、最强悍的掠食者之一，巨齿鲨的证据仅限于零散标本，其外观和最大体型仍不确定。科学家们对它更像大白鲨的结实型、鲸鲨（Rhincodon typus）、鲸鲨科的长嘴鲨（Cetorhinus maximus）或长牙鲨（Carcharias taurus）中的哪一种存在分歧。最近的估算在误差范围最小的情况下，最大长度可能达到约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)
