来自印尼爪哇，Cikalong 的真实巨齿鲨牙齿
高质量的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；学名 Otodus megalodon），意为“巨牙”，是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时期。它曾被认为属于锯鳐科 Lamnidae，与大白鲨（Carcharodon carcharias）有亲缘关系。但现今被归入已灭绝的 Otodontidae 科，与大白鲨在早白垩纪起就分化。 

尽管被公认为史上最大、最强大的掠食者之一，巨齿鲨仅从零散的遗骸得知，其外形和最大体型尚不确定。科学家对它更像大白鲨的矮胖版、鲸鲨（Rhincodon typus）、沐浴鲨（Cetorhinus maximus）还是沙虎鲨（Carcharias taurus）等哪种体型存在分歧。最近的估计在误差范围最小的情况下，最大体长可达约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)
