来自印尼，爪哇，Cikalong 的正品巨齿鲨牙

高品质巨齿鲨牙，尖端良好，具有锯齿和牙釉质，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是一种已灭绝的鲭鲨科成员，生活在大约2300万年前至360万年前的始新世至上新世时期。它曾被认为属于狼牙鲨科并与大白鲨（Carcharodon carcharias）关系密切。然而，现今被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪便已与大白鲨分化。

尽管被认为是有史以来最大的、最强的掠食者之一，巨齿鲨仍以碎片化遗骸为人所知，其外观和最大体型尚不确定。科学家对它更像是大白鲨的更矮壮版本、鲸鲨（Rhincodon typus）、抚鲸鲨（Cetorhinus maximus）还是虎齿鲨（Carcharias taurus）存在分歧。最新且误差范围最小的估计表明，其最大身长可达约20.3米（67英尺），体重可达约103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)
