来自印度尼西亚爪哇，Cikalong 的正品 Carcharocles megalodon 牙齿

高质量 Megalodon 牙齿，尖端完好，锯齿和珐琅质良好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“Big tooth”，是一种灭绝的鲭鲨科鲨鱼，生活在大约230万年前到360万年前的早中新生代至上新世。它曾被认为属于Lamni­dae科，与大白鲨（Carcharodon carcharias）亲缘关系密切。然而现在被归入已灭绝的 Otodontidae 家族，与大白鲨在早白垩纪就已分化。

尽管被认为是有史以来最大且最强大的掠食者之一，Megalodon 仅以不完整的遗骸为知，外形和最大体长尚不确定。科学家对它更接近哪一类而存在分歧：是更像体型更壮实的大白鲨、鲸鲨（Rhincodon typus）、抚鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）。最新且误差范围最小的估计表明其最大体长可达约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)
