来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，牙尖、锯齿和牙釉质完好，

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科动物，生活在大约2300万至360万年前（Mya），从早中新世到上新世。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入已灭绝的 Otodontidae 科，该科在早白垩纪就已与大白鲨分化。

尽管被认为是迄今为止最大、最强大的掠食者之一，巨齿鲨仅有碎片化遗骸可供了解，其外观和最大体长也不确定。科学家对它的外形存在分歧，认为它更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、日光鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最近的估计中，误差范围最小，最大长度估计可达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)
