来自印度尼西亚，爪哇，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭鱼鲨科物种，生活在大约230万年前至360万年前（中新世早期至上新世晚期）。它曾被认为属于 Lamnidae 家族并与大白鲨（Carcharodon carcharias）有密切亲缘关系。然而，现在归入已灭绝的 Otodontidae 家族，该科在早白垩世就与大白鲨分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨的化石仅有零散遗骸，其外形和最大体长尚不确定。科学家对它更像是大白鲨的更健壮版本、鲸鲨（Rhincodon typus）、抚鲨（basking shark，Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）更接近存在分歧。最近的估计在误差范围最小的情况下，最大体长可达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)
