高质量的巨齿鲨牙，尖端良好，具备锯齿和牙釉质

Megalodon (/ˈmɛɡələdɒn/ MEG-əl-ə-don; Otodus megalodon)，其名字意为“巨齿”，是一种已灭绝的鲭鱼鲨科动物，约生活在2300万至360万年前的早中新世至晚中新世时期。它曾被认为属于鲭鲨科（Lamnidae），与大白鲨（Carcharodon carcharias）关系密切。然而现今归入已灭绝的 Otodontidae 科，与大白鲨在早白垩世分化。

尽管被认为是有史以来最大、最强大的掠食者之一，但巨齿鲨仅以碎片化的化石为人所知，其外观和最大体型尚不确定。科学家对其外形是否更接近大白鲨的矮胖版本、鲸鲨（Rhincodon typus）、滑鳃鲨（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）存在分歧。最新、误差最小的估计表明其最大长度可达约20.3米（67英尺），体重可达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)
