真实的巨齿鲨牙来自印尼，爪哇，Cikalong

优质巨齿鲨牙，尖端完好，锯齿和珐琅质完好

巨齿鲨（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鱼鲨科动物，生活在约2300万至360万年前（中新世早期至中新世晚期）。它曾被认为属于鲭科家族(Lamnidae)，与大白鲨(Carcharodon carcharias)关系密切。然而现在被归入已灭绝的 Otodontidae 家族，该家族在早白垩纪就已与大白鲨分道。

尽管被认为是有史以来最大、最强力的捕食者之一，巨齿鲨只留有零碎化石，其外形和最大体长仍不确定。科学家对它更像大白鲨的粗壮版、鲸鲨(Rhincodon typus)、抑或吻鲨(Cetorhinus maximus)或砂虎鲨(Carcharias taurus)的看法不一。最近的估计，误差范围最小的最大体长约为20.3米（67英尺），体重最高可达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)
