来自印度尼西亚，爪哇岛，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，齿锯齿良好，牙尖和牙釉质完好，

巨齿鲨（Carcharocles megalodon）/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon，意为“ giant tooth/大牙齿”，是一种已灭绝的鲭鲨科动物，生活在约2300万至360万年前（Mya），从早中新世到上新世时期。它曾被认为属于鲭鲨科，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入已灭绝的 Otodontidae 科，该科在早白垩纪与大白鲨分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，其外形和最大体长仍不确定。科学家们对于它更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、海狗鲨或沙虎鲨（Carcharias taurus）等中的哪一种意见不一。最近的估计在误差较小的情况下，最大体长可达约20.3米（67英尺），体重约103吨（114短吨）。

Authentic Carcharocles megalodon tooth from Indonesia, Java , Cikalong 

Quality Megalodon Tooth, with good  serrations, tip , 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)
