来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨（Megladon）牙齿

高质量巨齿鲨牙，尖端完好、锯齿与珐琅质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨，生活在约2300万至360万年前的始中新世到中新世末期。它曾被认为属于长鳍鲨科，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 家族，与大白鲨在早白垩纪分化。

尽管被认为是有史以来最大、最强力的掠食者之一，巨齿鲨仅以零散化石为人知，其外形和最大体型仍不确定。科学家对于它更像大白鲨的哪种体态、还是像抹香鲸、浮鲨（Cetorhinus maximus）或海虎牙鲨（Carcharias taurus）等，意见不一。最新且误差范围最小的估计显示，最大体长可达约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)
