来自印度尼西亚，爪哇，Cikalong 的正品巨齿鲨牙

高质量巨齿鲨牙，尖端完好，锯齿清晰，牙釉质完整，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭形鲨类，生活在大约 2300 万年前到 360 万年前的始新世至中新世。曾被认为属于鲭科并与大白鲨（Carcharodon carcharias）关系密切。然而，现将其归入已灭绝的 Otodontidae 科，该科在早白垩纪便与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅凭零散遗骸才被了解，其外形和最大体型仍不确定。科学家们对它更像是大白鲨的高壮版本、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近一项误差范围最小的估计显示，最大身长可达约 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)
