来自印尼·爪哇的正宗巨齿鲨牙，Cikalong 出品

高品质巨齿鲨牙，尖端、锯齿和牙釉质完好

巨齿鲨（Megalodon /ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨大之牙”，是一种已灭绝的鲭鲨科鲨鱼，生活在约230万至360万年前（始新世至上新世）。它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，与大白鲨在早白垩世分道两岔。

尽管被认为是有史以来最大、最强大的捕食者之一，巨齿鲨的证据仅限于碎片化的遗骸，其外观和最大体长尚不确定。科学家们对它更像是大白鲨的健壮版、抹香鲸（Rhincodon typus）、巨齿鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）的哪一种存在分歧。最近的估计在误差范围最小的情况下，最大长度可达约20.3米（67英尺），体重可达约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)
