来自印尼爪哇岛Cikalong的正品Carcharocles megalodon牙齿

高质量的巨齿鲨牙，尖端完好，齿锯齿和牙釉质完好，

Megalodon (/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，约生活在2300万至360万年前（Mya），跨越早中新世至上新世时期。此前曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）有密切关系。然而现今被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪与大白鲨分道扬镖。

尽管被视为史上最大、最强大的掠食者之一，巨齿鲨仅以零散化石为据，外形与最大体型仍不确定。科学家对它的外形更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、抬头鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等哪一种意见不一。最新的、误差范围最小的估算显示其最大身长可达约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)
