来自印尼爪哇，Cikalong 的Authentic Carcharocles megalodon 牙齿 

品质优良的 Megalodon 牙齿，尖端、锯齿和牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年至360万年前（中新世早期至中新世-始新世）之间。它曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）有密切关系。但如今被归入已灭绝的 Otodontidae 家族，与大白鲨在早白垩世阶段分化。

尽管被视为有史以来最大、最强大的掠食者之一，Megalodon 的化石记录仅零星残骸，其外形与最大体长仍不确定。科学家对它更像哪一种鲨鱼存在分歧：更接近体型较敦实的大白鲨、鲸鲨（Rhincodon typus）、巨口鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）。最近的估计在误差范围最小的情况下，最大身长可达约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)
