优质巨齿鲨牙齿，尖端、锯齿和牙釉质完好。

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“大牙”，是一个灭绝的鲭鲨科鲨鱼物种，生活在约2300万年前至360万年前的始中新世至上新世。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）有亲缘关系。但如今被归入灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分化。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨的化石记录仅存碎片，外形和最大体型尚不确定。科学家对它更像是大白鲨的更粗壮版本、鲸鲨、抚浪鲨还是沙虎鲨存在分歧。最近的保守估算给出的最大长度可达约20.3米（67英尺），体重可达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)
