来自印尼爪哇，Cikalong 的正品巨齿鲨牙

质量优良的巨齿鲨牙，牙尖完好，锯齿和牙釉质良好。

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don； Otodus megalodon），意为“巨大的牙齿”，是一种已灭绝的鲭鲨科鲛类，生活在大约2300万至360万年前的新近纪早期到中新世晚期。它曾被认为属于露脊鲸科家族，与大白鲨（Carcharodon carcharias）关系密切。然而现在被归类于已灭绝的 Otodontidae 家族，与大白鲨在白垩纪早期分化。

尽管被认为是有史以来最庞大、最强大的掠食者之一，巨齿鲨的证据仅有零散化石，其外形和最大体长尚不确定。科学家对其外形的看法存在分歧：它更像大白鲨的结实版、抹香鲸（Rhincodon typus）、浮头鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）。最近的估计中，误差范围最小的最大长度估计为约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)
