来自印尼爪哇岛Cikalong的正品巨齿鲨（Carcharocles megalodon）牙齿

高质量的巨齿鲨牙齿，尖端、锯齿和牙釉质完好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon）意为“巨大牙齿”，是已灭绝的鲭鲨科鲨鱼，约在230万年前至360万年前的始中新世至上新世时期生活。它曾被认为属于长鳍鲨科，与大白鲨（Carcharodon carcharias）有密切关系。但现在归入已灭绝的Otodontidae科，该科与大白鲨在白垩纪早期分道扬镳。

尽管被认为是有史以来最庞大、最强大的捕食者之一，巨齿鲨的化石残存零散，外形和最大体型仍不确定。科学家对它更像大白鲨的结实版本、鲸鲨（Rhincodon typus）、鲸鲨、还是沙虎鲨（Carcharias taurus）等不同形态存在分歧。最近一次的估算给出的误差范围最小，最大身长可达约20.3米（67英尺），体重可达约103公吨（114短吨）。

长度：4.9 cm

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)
