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，尖端、锯齿和珐琅质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种已经灭绝的鲭鱼鲨科成员，大约生活在2300万至360万年前的中新世早期至更新世晚期。曾被认为属于鲭科 Lamnidae家族，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪时期已从大白鲨分化出。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨只是以碎片化的化石为所知，它的外貌和最大体型仍不确定。科学家对于它更像是大白鲨的更壮实版本、鲸鲨（Rhincodon typus）、浮头鲨（Cetorhinus maximus）还是锥牙鲨（Carcharias taurus）的看法各不相同。最近的估计在误差范围最小的情况下，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)
