来自印度尼西亚爪哇岛 Cikalong 的正品巨齿鲨（Carcharocles megalodon）牙。 

高品质的巨齿鲨牙，尖端、锯齿和牙釉质完好。 

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨型牙齿”，是一种已灭绝的鲭形鲨，生活在大约2300万年前至360万年前（中新世早期至上新世晚期）。它曾被认为属于鲭科的成员，且与大白鲨（Carcharodon carcharias）关系密切。然而，现今将其归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已从大白鲨分化出来。

尽管被广泛认为是有史以来最巨大、最强大的掠食者之一，巨齿鲨只以零散的遗骸为人所知，其外观和最大体长仍不确定。科学家对其最接近的体态有不同看法：有认为它更像大白鲨的肌肉型、抹香鲸（Rhincodon typus）的体型，还是鲸鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）。最近的估计在误差范围最小的情况下，最大身长约为20.3米（67英尺），体重可达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)
