优质美加龙牙齿，尖端完好，锯齿清晰，牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“大牙”，是一种已灭绝的鲭鱼鲨，生活在约2300万年至360万年前的始新世至中新世之间。它曾被认为属于鲭科，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪期间与大白鲨分支。

尽管被认为是有史以来最大、最强大之一的掠食者，美加龙仅以碎片化的骨骼被知晓，其外形和最大体型仍不确定。科学家对其更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、须鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）的看法不一。最近的估计给出误差范围较小的最大体长约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)
