来自印度尼西亚爪哇岛Cikalong的正宗巨齿鲨牙齿

优质巨齿鲨牙齿，尖端、锯齿和牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是已灭绝的鲭鲨科动物，生活在约2300万年前至360万年前之间，跨越早中新世至上新世晚期。它曾被认为属于鲭科，与大白鲨（Carcharodon carcharias）关系密切，但现在被归类于已灭绝的 Otodontidae 科，该科在白垩纪早期就与大白鲨分道扬镳。

尽管被普遍认为是有史以来最大、最强力的掠食者之一，巨齿鲨仅以断续的化石证据为人所知，其外形和最大体型仍不确定。科学家对其更像是大白鲨的结实版本、鲸鲨（Rhincodon typus）、抚摸鲨（Cetorhinus maximus）或虎鲨（Carcharias taurus）等哪一类存在分歧。最近的估计在误差范围最小的情况下，最大身长可达约20.3米（约67英尺），体重可达103公吨（约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)
