来自印尼爪哇Cikalong的真实大白鲨牙齿 Megalodon（大齿鲨）化石，品质优良，牙尖、锯齿和牙釉质完好。

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科动物，大约生活在23至360万年前的始中新世至上新世时期。它曾被认为是Lamnidae科的成员，与大白鲨（Carcharodon carcharias）关系密切。但现今归入已灭绝的Otodontidae科，该科在早白垩世就已与大白鲨分化。

尽管被公认为有史以来最强大、捕食力最强的掠食者之一，Megaldon 的化石仅由碎片构成，其外观和最大体型尚不确定。科学家对其更像大白鲨的笔直版、鲸鲨（Rhincodon typus）、鲸鲨、还是虎鲨（Carcharias taurus）等的猜测不一。最新且误差范围最小的估计显示，最大体长可达约20.3米（67英尺），体重可达约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)
