来自印度尼西亚爪哇，Cikalong 的正品 Megalodon（Carcharocles megalodon）牙齿

高质量的 Megalodon 牙齿，尖端、锯齿和牙釉质完好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意思是“巨齿”，是一种灭绝的鲭齿鲨科鲨鱼，生活在大约2300万到360万年前（Mya），始新世至上新世时期。它曾被认为属于 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切。然而，如今被归入已灭绝的 Otodontidae 科，该科在早白垩世就与大白鲨分道。

尽管被视为史上最大、最强的掠食者之一，猛鲨仅以碎片化遗骸为人所知，其外形和最大体型仍然不确定。科学家对其外形更接近大白鲨的厚实版本、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等哪一种存在分歧。最近的估计在误差范围最小的情况下，最大体长可达约20.3米（67英尺），体重可达约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)
