来自印尼爪哇，Cikalong 的正品巨齿鲨牙

高品质巨齿鲨牙，锯齿锋利，牙尖和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“big tooth”，是已灭绝的鲭鲨科鲨鱼，约在2300万年前到360万年前（Mya）的始新世早期至中新世晚期生活过。它曾被认为属于露脊鲨科Lamnidae，与大白鲨（Carcharodon carcharias）有密切关系。但现在被归类为已灭绝的Otodontidae家族，该家族在早白垩纪就已与大白鲨分道。

尽管被认为是有史以来最大且最强大的掠食者之一，巨齿鲨的知之仅限于碎片状遗骸，其外观和最大尺寸尚不确定。科学家们对它更接近大白鲨的健壮版本、鲸鲨（Rhincodon typus）、沐鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间的关系存在分歧。最近的估算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  serrations, tip , 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)
