来自印尼爪哇岛Cikalong的真实Carcharocles megalodon牙齿

高质量的巨齿鲨牙齿，尖端完好，锯齿清晰，牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在约230万年前至360万年前（中新世早期至中新世晚期）。它曾被认为属于鲭鲨科（Lamnidae）并与大白鲨（Carcharodon carcharias）关系密切。然而，现在它被归类于灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分道扬镳。

尽管被视为有史以来最庞大、最强力的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，它的外形和最大体型仍存在不确定性。科学家对它更接近于大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等的看法不一。最近一次以误差范围最小的估算显示，最大体长可达约 20.3 米（67 英尺），体重可达约 103 公吨（114 短吨）

长度：13.5 cm

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)
