来自印度尼西亚爪哇岛Cikalong的真实巨齿鲨（Carcharocles megalodon）牙齿

高品质巨齿鲨牙齿，尖端、锯齿和珐琅质完好。

巨齿鲨（Megalodon/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“大牙齿”，是一种已灭绝的鲭鲨科成员，生活在大约2300万年前至360万年前的中新世早期到上新世时期。从前被认为属于灯)=> Lamnidae科，与大白鲨（Carcharodon carcharias）有密切关系。然而现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就与大白鲨分化开来。

尽管被认为是史上最大的、最强大之一的掠食者，巨齿鲨仅以碎片状的遗骸为人所知，其外形和最大体型仍不确定。科学家对于它更像大白鲨的躯干型 Variants、抹鲸的形态、蓝鲸鲨的外观、还是沙虎鲨（Carcharias taurus）等谁更相近存在分歧。最近一个最小误差区间的估计显示，最大长度可达约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)
