高质量的巨齿鲨牙，尖端良好，锯齿和牙釉质完好，

Megadalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭鱼鲨科物种，大约在距今2300万年至360万年前的始新世到中新世期间生活。它曾被认为属于鲭科，与大白鲨（Carcharodon carcharias）关系密切。然而，现今归入已灭绝的Otodontidae科，该科在早白垩纪时期就已与大白鲨分化。

尽管被认为是有史以来最强大、捕猎力最强的生物之一，巨齿鲨的证据仅限于碎片化的化石，其外形与最大体型仍不确定。科学家对它更接近大白鲨的笨重体型、鲸鲨（Rhincodon typus）、大白鲨的海狗鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）等的外观存在分歧。最新的估算给出的最大长度在约20.3米（67英尺），体重可达103公吨（114短吨）。

长度：6.4 cm

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)
