来自印尼爪哇、Cikalong 的正宗 Carcharocles megalodon 牙齿

高质量的巨齿鲨牙，尖端良好，具备锯齿和牙釉质

Megaldon（/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“巨大牙齿”，是已灭绝的鲭科鲨鱼物种，生活在大约2300万年前至360万年前的始新世到中新世之间。其归属曾被认为是 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切。但现在它被归类于已灭绝的 Otodontidae 家族，该科在早白垩纪就已从大白鲨分化出来。

虽然被公认为有史以来最大、最强大的一些掠食者之一，巨齿鲨仅以碎片化的化石为人所知，其外观和最大体型仍不确定。科学家对其外观的具体形态存在分歧：是更像大白鲨的健壮版本、抹香鲸（Rhincodon typus）或鲸鲨、温暖的海洋鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）的形态。最近的、误差范围最小的估算表明，最大身长可达约 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)
