品质巨齿鲨牙，尖端、锯齿和珐琅质良好，

Megalodon（/ˈmɛɡələdɒn/ MEG-əl-ə-don；Otodus megalodon），意为“巨齿”，是一种已灭绝的鲭鲨科鲨鱼，约在2300万年前至360万年前的始新世至上新世期间生活。它曾被认为属于鲭鲨科 Lamnidae，与大白鲨（Carcharodon carcharias）关系密切。然而现在归入已灭绝的 Otodontidae 科，与大白鲨在早白垩世便分化。

尽管被认为是有史以来最庞大、最强大的掠食者之一，但巨齿鲨仅存留有零散的遗骸，其外形和最大体长尚不确定。科学家对它更接近大白鲨的矮胖型、鲸鲨（Rhincodon typus）、浮鳐（Cetorhinus maximus）或沙虎鲨（Carcharias taurus）之间有不同意见。

最新且误差范围最小的估算表明其最大体长可达约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)
