来自印度尼西亚爪哇岛 Cikalong 的真品巨齿鲨牙 

高质量的巨齿鲨牙，尖端良好，锯齿和牙釉质完好， 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种已灭绝的鲭鱼鲨类，生活在大约2300万至360万年前（Mya），从中新世早期到上新世晚期。它曾被认为属于Lam­nidae科，与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归类于已灭绝的 Otodontidae 家族，该科在早白垩纪就已与大白鲨分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的化石证据仅为零散片段，其外形和最大体长尚不确定。科学家对于它更像大白鲨的紧凑型、鲸鲨（Rhincodon typus）、抹香鲸或虎齿鲨（Carcharias taurus）等哪一类仍有分歧。最新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)
