来自印度尼西亚爪哇岛Cikalong的 authentic Carcharocles megalodon牙齿。

高质量的巨齿鲨牙齿，尖端、锯齿和牙釉质都保存完好。

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种已灭绝的鲭鱼鲨，生活在约2300万年前至360万年前的始新世至上新世。它曾被认为属于Lamnidae科，与大白鲨(Carcharodon carcharias)关系密切；但现今被归入已灭绝的Otodontidae科，在早白垩世就与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的化石仅有零星残存，外形与最大体型仍不确定。科学家对它到底更像大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、鲸鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近一次最保守的估计给出的最大长度约为20.3米（67英尺），体重可达103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)
