来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙齿

优质的巨齿鲨牙齿，尖端完好，锯齿清晰，牙釉质完好，

巨齿鲨（Megalodon，/ˈmɛɡələdɒn/ MEG-əl-ə-don；学名 Otodus megalodon），意为“巨大之牙”，是一种已经灭绝的鲭鲨科鲨鱼，生活在约2300万年前至360万年前的始新世至上新世时期。它曾被认为属于鲭科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切；然而现在被归入已灭绝的 Otodontidae 家族，该科在早白垩纪便已与大白鲨分道。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅从零散的遗骸得知，其外形和最大体型仍不确定。科学家对其外观的猜测存在分歧，可能更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）中的哪一种，最近的估算在误差最小的区间内提出，最大身长可达20.3米（67英尺），体重可达103吨（114短吨）

长度 11,3 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)
