印尼爪哇、Cikalong 的正宗长牙鲨巨齿牙

高质量巨齿鲨牙，尖端完好、锯齿和牙釉质俱佳，

巨齿鲨 (/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2300万至360万年前的早中新世至上新世。此前被认为属于狼鲨科，是大白鲨(Carcharodon carcharias)的近亲。然而，现今被归类于已灭绝的 Otodontidae 科，与大白鲨在早白垩世就已分化。

尽管被认为是有史以来最大、最具力量的掠食者之一，巨齿鲨只知其碎片化的遗骸，其外形与最大体型仍存疑。科学家对其更接近哪一种鲨鱼仍有分歧：是更接近大白鲨的健壮版、鲸鲨( Rhincodon typus )、护鳐鲨(Cetorhinus maximus)还是沙虎鲨(Carcharias taurus)。最新且误差范围较小的估计表明，最大Length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)
