来自印尼爪哇，Cikalong 的正宗 Carcharocles megalodon 牙齿

高质量的巨齿鲨牙齿，尖端、锯齿和牙釉质完好，

Megadallon（MEG-əl-ə-don；意为“Big Tooth”）是一种已灭绝的鲭型鲨鱼，约在2000万年前至356万年前（中新世早期至上新世）生活。此前被认为属于 Lamnidae 科，并且与大白鲨（Carcharodon carcharias）关系密切。然而，现在被归入已灭绝的 Otodontidae 科，该科在白垚鲨在早白垩纪就已分化。

尽管被认为是有史以来最大、最强大的掠食者之一，巨齿鲨仅有零散遗骸，因此其外形和最大体型尚不确定。科学家们对它更像白鲨的健壮版本、鲸鲨（Rhincodon typus）、浮鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之中的哪一种存在分歧。最近的估计（误差范围最小）显示其最大长度可达约20.3米，体重可达约103公吨。

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)
