优质巨齿鲨牙齿，尖端完好，齿锯齿和牙釉质完好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨牙”，是一种已灭绝的鲭科鲨鱼，生活在大约2300万至360万年前，始新世早期至上新世时期。它曾被认为属于旗鱼科，与大白鲨（Carcharodon carcharias）关系密切。然而，现今被归入已灭绝的 Otodontidae 家族，该科在早白垩纪时期与大白鲨分道扬镳。

尽管被认为是有史以来最大、最强的掠食者之一，巨齿鲨仅以零散的遗骸为人所知，其外形和最大体型尚不确定。科学家对其外形更接近大白鲨的粗壮版本、鲸鲨（Rhincodon typus）、还是沙虎鲨（Carcharias taurus）有不同的看法。最近的估计在误差范围最小的情况下，最大身长约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)
