来自印尼爪哇岛 Cikalong 的正品巨齿鲨牙齿

优质巨齿鲨牙，尖端、锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），其名意为“巨牙”，是一种已灭绝的鲭鲨科动物，大约生活在距今约2300万年至360万年前的中新世早期至鄂新世末期。曾被认为属于鲭科（Lamnidae）并且与大白鲨（Carcharodon carcharias）关系密切；然而现在被归入灭绝的 Otodontidae 家族，该家族在早白垩纪时就与大白鲨分道扬镳。

尽管被认为是有史以来最大且最强的掠食者之一，巨齿鲨仅以碎片状的遗骸为人所知，其外形与最大体长尚不确定。科学家对于它更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、抚摸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）之间的看法不一。最新的、误差范围最小的估计显示，其最大体长可达约20.3米（67英尺），体重高达103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)
