来自印度尼西亚爪哇(Cikalong)的真实 Carcharocles megalodon 牙齿

高品质巨齿鲨牙，尖端良好，锯齿清晰，牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种灭绝的鲭鲨科动物，约在2300万到360万年前的始新世至上新世时期生活。它曾被认为属于鲭鲨科，与大白鲨(Carcharodon carcharias)关系密切。然而，现归入已灭绝的 Otodontidae 科，与大白鲨在早白垩世分道扬镳。

尽管被视为有史以来最大、最强的掠食者之一，巨齿鲨仅以碎片化的遗骸为人所知，其外观和最大体型尚不确定。科学家对它更像是体格更健壮的大白鲨版本、鲸鲨(Rhincodon typus)、抚鲨(Cetorhinus maximus)还是沙虎鲨(Carcharias taurus)存在分歧。最新且误差范围最小的估计显示，最大长度可达约20.3米（67英尺），体重可达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)
