来自印度尼西亚爪哇岛，Cikalong 的正品巨齿鲨牙

高质量的巨齿鲨牙，尖端、锯齿和牙釉质完好，

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万至360万年前的中新世早期至上新世时期。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切。然而，现将其归入已灭绝的 Otodontidae 家族，该科在早白垩纪时期便与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅以零碎化石为人所知，其外形和最大体长尚不确知。科学家对于它更像大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、还是细鳃鲨（沙虎鲨，Carcharias taurus）有分歧。最近的估计（误差范围尽可能小）显示其最大身长可达约20.3米（67英尺），体重可达约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)
