来自印尼爪哇，Cikalong 的正品巨齿鲨牙

高品质的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鲨科巨鲨，生活在大约2300万到360万年前（中新世早期至上新世）。此前曾被认为属于 Lamnidae 科，与大白鲨（Carcharodon carcharias）关系密切；但现归入已灭绝的 Otodontidae 家族，该家族于早白垩纪即与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，其外观和最大体长仍不确定。科学家对于它的外形更接近大白鲨的结实版、鲸鲨（Rhincodon typus）、浮鳍鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）存在分歧。最近且误差范围最小的估计表明，其最大长度可达约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)
