来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙齿

高品质 Megalodon 牙齿，尖端完好，锯齿与牙釉质完好，

巨齿鲨（Otodus megalodon，学名 Otodus megalodon），意为“大牙”，是一种已灭绝的鲭鲨科动物，约在2300万年前至360万年前的中新世早期至上新世之间生存。它曾被认为属于鲭鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而，现已归入已灭绝的 Otodontidae 科，该科在早白垩纪便已与大白鲨分道。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以碎片化遗骸为人所知，其外形和最大体型尚不确定。科学家对于它更接近大白鲨的健壮体型、鲸鲨（Rhincodon typus）、抹牙鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近的、误差范围最小的估计表明其最大体长可达约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)
