来自印度尼西亚爪哇岛 Cikalong 的正品大白鲭鲨牙齿 Megalodon（Megalodon）

高品质 Megalodon 牙齿，牙尖、锯齿和釉层均完好

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“大牙”，是一种已灭绝的鲭鲨科物种，生活在大约2300万年至360万年前的始新世至中新世。它曾被认为属于鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。但现今被归入已灭绝的 Otodontidae 家族，在早白垩世就已与大白鲨分道而立。

尽管被视为史上最大的、最强大的掠食者之一，Megalodon 的化石记录零散，外形与最大体长仍不确定。科学家对它更像大白鲨的哪种变体、抹香鲸鲨（Rhincodon typus）、巨牙鲨（Cetorhinus maximus）还是沙胸鲨（Carcharias taurus）存在分歧。最近一次最小误差范围的估计给出最大长度可达约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)
