来自印度尼西亚爪哇岛Cikalong的正品Carcharocles megalodon牙齿

高品质巨齿鲨牙齿，尖端、锯齿和琺质完好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年前至360万年前的始新世晚期至上新世时期。它曾被认为属于Lamnidae科，与大白鲨（Carcharodon carcharias）有密切亲缘关系。然而，现今被归入已灭绝的Otodontidae科，在早白垩纪就已与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化化石为知，外形和最大体型尚不确定。科学家对它究竟更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、抚鳐鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近的估算在误差最小的情况下给出最大长度约为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)
