来自印度尼西亚爪哇，Cikalong 的真品巨齿鲨牙

优质巨齿鲨牙，尖端、锯齿和釉质完好，

巨齿鲨（Carcharocles megalodon； Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鲨目鲨鱼，生活在大约2300万至360万年前（中新世早期至上新世）。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，如今被归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪就已分支。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散遗骸为人所知，其外观和最大体长仍不确定。科学家对于它更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近的估计在误差范围最小的情况下，最大身长可达约20.3米，体重约103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)
