来自印度尼西亚爪哇，Cikalong 的正品巨齿鲨牙齿

高品质巨齿鲨牙齿，尖端良好、锯齿清晰、牙釉质完好，

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，意为“巨牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在大约2300万至360万年前的始新世早期至上新世时期。它曾被认为属于长须鲨科并与大白鲨(Carcharodon carcharias)有密切关系，但现今归入已灭绝的 Otodontidae 家族，该家族在早白垩纪便已与大白鲨分支开来。

尽管被视为有史以来最庞大、最强大之一的掠食者，但巨齿鲨仅以零散遗骸为人所知，其外形和最大体型仍不确定。科学家对它更接近大白鲨的粗壮型、鲸鲨 (Rhincodon typus)、抹拍鲨 (Cetorhinus maximus) 还是沙虎鲨 (Carcharias taurus) 各有不同看法。最近的估算在误差最小的情况下，最大身长可达约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)
