来自印度尼西亚的爪哇，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，尖端良好，锯齿清晰，牙釉质完好，

巨齿鲨（Megalodon，音标 /ˈmɛɡələdɒn/，MEG-əl-ə-don； Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，约在2300万年至360万年前的早中新世至上新世期间生活。它曾被认为属于 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切。然而如今被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就与大白鲨分道。

虽然被认为是有史以来最大且最强大的掠食者之一，巨齿鲨仅有零碎遗骸可供研究，其外形和最大体型仍不确定。科学家对于它是否更像大白鲨的矮壮版、抹香鲸（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近的估计在误差范围最小的前提下，最大身长可达约20.3米（67英尺），体重可达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)
