来自印度尼西亚爪哇 Cikalong 的真实 Carcharocles megalodon 牙齿

高品质美拉格龙牙，尖端完好，锯齿和牙釉质良好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon)，意为“大牙”，是已灭绝的鲭鲨科/相关物种，约生活在2300万到360万年前（百万年前，Mya），从中新世早期到上新世末期。
它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。但现在归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就与大白鲨分化。

尽管被视为有史以来最大、最强大的掠食者之一，美拉格龙只知之于零散遗存，其外形和最大体长仍不确定。科学家对它更像是大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、澡鲨或沙虎鲨的近似形态意见不一。最新的估计中，最大长度可达约20.3米（67英尺），体重约103吨（114短吨）。

长度：11.2 cm

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)
