来自印度尼西亚爪哇岛 Cikalong 的正宗巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端、锯齿和琺质都完好

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万至360万年前（Mya），从中新世早期到上新世。它曾被认为属于鲭鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。但现在被归入已灭绝的 Otodontidae 科，该科在早白垩世就已与大白鲨分化。

尽管被公认是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散遗骸为人所知，其外形和最大体长尚不确定。科学家对其外观的看法各不相同，可能更接近体型较为健壮的大白鲨、鲸鲨（Rhincodon typus）、巨牙鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最新估算（误差最小）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）。

长度：11.1厘米

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)
