来自印度尼西亚爪哇，Cikalong 的正宗巨齿鲨牙 

优质的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“Big tooth（大牙）”，是一种已灭绝的鲭鲨科鲨鱼，生活在约2300万年前至360万年前（中新世早期到鮟？纪）之间。它曾被认为属于鲭鲨科并与大白鲨（Carcharodon carcharias）有紧密关系。然而，现今被归入灭绝的 Otodontidae 家族，该科在早白垩纪从大白鲨分化而来。

尽管被认为是有史以来最大、最强力的掠食者之一，巨齿鲨的遗骸仅有零散残存，其外观与最大体型仍不确定。科学家对其是否更像大白鲨的较为结实版本、鲸鲨（Rhincodon typus）、鲸口鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等的看法不一。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)
