来自印尼爪哇，Cikalong 的真实大白鲨巨齿 Megalodon 的牙齿

高质量 Megalodon 牙齿，牙尖、锯齿和珐琅质完好

Megalodon (/ˈmɛɡələˌdɒn/ MEG-əl-ə-don；Otodus megalodon)，意为“大牙”，是一种已灭绝的鲭鲨科，生活在大约2300万至360万年前的始中新世至上新世时期。它曾被认为属于锯鳐目，且与大白鲨(Carcharodon carcharias)关系亲近。但现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪与大白鲨分道扬镳。

尽管被公认为有史以来最大、最强悍的捕食者之一，Megalodon 的化石仅存片段，其外形和最大体型仍不确定。科学家对它更像是大白鲨的结实版、鲸鲨(Rhincodon typus)、浮头鲨(Cetorhinus maximus)或沙虎鲨(Carcharias taurus) 的看法各不相同。最近的估计给出的误差范围最小，最大长度可达约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)
