来自印度尼西亚 Java，Cikalong 的正品巨齿鲨牙齿

高质量的巨齿鲨牙齿，尖端、锯齿和珀质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大之牙”，是一类已灭绝的鲭鲨科物种，生活在大约2300万年至360万年前，从中新世早期到上新世。它曾被认为属于长鳍鲨科，是大白鲨（Carcharodon carcharias）的近亲。然而现今被归入已灭绝的 Otodontidae 家族，该科在早白垩纪就与大白鲨分化。

尽管被公认为有史以来最大、最强大的掠食者之一，巨齿鲨仅以零散的化石残骸为人所知，其外观和最大体型尚不确定。科学家们对其外形的具体相似性存在分歧：更像是体型更健壮的白鲨、鲸鲨（Rhincodon typus）、抹须鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）。最新的、误差范围最小的估计表明，其最大长度可达约20.3米（67英尺），体重可达约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)
