来自印尼Java的正品巨齿鲨牙，来自Cikalong。

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；Otodus megalodon），意为“巨齿”，是已灭绝的鲭鲨科掠食动物，生活在大约2300万至360万年前，即中新世早期至上新世时期。曾被认为属于鲭鲨科，与大白鲨（Carcharodon carcharias）关系密切；但现今归入已灭绝的 Otodontidae 家族，该家族与大白鲨在早白垩纪时期分化。

尽管被视为有史以来最大、最强大的掠食者之一，巨齿鲨的化石残骸仅零散可得，其外观与最大体长仍不确定。科学家对其外形的猜测存在分歧，可能更像是大白鲨的结实版本、鲸鲨（Rhincodon typus）、抹鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）的某种混合形态。最新且误差最小的估计显示，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)
