来自印尼爪哇，Cikalong 的正品巨齒鯊牙（Carcharocles megalodon）

高品質的巨齒鯊牙，尖端完好、鋸齒清晰、琺瑯質完好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don，Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，约在始新世早期至中新世晚期，即大约2300万年前至360万年前之间生活过。它曾被认为属于鲭科 Lamnidae，并与大白鲨（Carcharodon carcharias）关系密切。然而现在被归入已灭绝的 Otodontidae 科，该科在早白垩纪就已从大白鲨分化出来。

尽管被认为是史上最大、最强大的掠食者之一，巨齿鲨仅从碎片化的化石证据得知，其外形和最大体长仍不确定。科学家对其更接近于大白鲨的紧实体型、鲸鲨（Rhincodon typus）、浮鳃鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）有不同看法。最新的最小误差区间估计，最大体长可达约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)
