来自印尼爪哇，Cikalong 的真实巨齿鲨（Carcharocles megalodon）牙齿
Quality Megalodon Tooth, with good tip, serrations , and enamel,

巨齿鲨（ Otodus megalodon），音标 /ˈmɛɡələdɒn/ MEG-əl-ə-don，意为“巨大牙齿”，是已灭绝的鲭鲨科鲨鱼物种，生活在约2300万至360万年前的始新世至上新世时期。它曾被认为属于鲭科并且是大白鲨（Carcharodon carcharias）的近亲。然而，现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分道扬镳。

尽管被公认为有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，其外观和最大体型仍不确定。科学家们对其更接近哪种体型存在分歧：更像大白鲨的健壮版本、鲸鲨（Rhincodon typus）、抬头鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最新且误差范围最小的估计表明，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)
