真实的 Indonesi 的巨齿鲨牙，来自印尼，爪哇，Cikalong

高质量的巨齿鲨牙，牙尖完好，锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大牙齿”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万年前至360万年前（从始新世早期到上新世晚期）。曾被认为属于 Lamnidae 家族，与大白鲨（Carcharodon carcharias）关系密切；但现今归入已灭绝的 Otodontidae 家族，该科在早白垩纪就与大白鲨分道扬镳。

尽管被认为是有史以来最大的、最强大的捕食者之一，巨齿鲨只以碎片性遗骸为人所知，其外观和最大体型尚不确定。科学家对其是否更接近体型更粗壮的大白鲨、鲸鲨、抬头鲨还是沙虎鲨存在分歧。最新的估计，误差最小，最大体长约20.3米（67英尺），体重约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)
