正品 Carcharocles megalodon 牙齿，来自印尼，爪哇，Cikalong 

优质 Megalodon 牙齿，尖端完好，齿锯齿锋利，瓷质光洁，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨大牙齿”，是已灭绝的鲭鲨科鲨鱼，约生活在1,300万至360万年前（中新世早期至上新世），从早始新世到上新世。此前被认为属于灯笼鳐科并且与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归类于已灭绝的 Otodontidae 家族，该家族在白鲨出现的早白垩纪就已分化。

尽管被认为是史上最大、最强大的捕食者之一，巨齿鲨的化石残留极为零散，因此其外形和最大体长仍不确定。科学家对其更像大白鲨的健壮版、鲸鲨（Rhincodon typus）、张牙鲨（Cetorhinus maximus）或沙锯鲨（Carcharias taurus）等的看法不同。最新且误差区间最小的估计显示，其最大长度可达约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)
