高质量的巨齿鲨牙，尖端锯齿清晰，牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大的牙齿”，是一种已灭绝的鲭形鲨科动物，生活在大约2300万年前至360万年前的早中新世至上新世时期。它曾被认为属于鲭科并与大白鲨（Carcharodon carcharias）有密切关系。然而，现今将其归入已灭绝的 Otodontidae 家族，该家族在早白垩纪时期就已与大白鲨分化。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨仅以不完整的遗骸为人所知，其外观和最大体长仍不确定。科学家对于它更像大白鲨的哪种形态、还是鲸鲨（Rhincodon typus）、鲸鲨或锤头鲨（Carcharhinus taurus）之间存有分歧。最近的估计，误差范围最小的结果显示其最大身长可达约 20.3 米（约 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)
