Otodus megalodon – 化石牙齿
新近纪，始新世（23.03 – 5.33百万年前） – 印尼
极为罕见的 Otodus megalodon 化石牙齿标本，地球上有史以来发现的最大的鲨鱼，约在 360 万年前灭绝。
特征：
形状：三角形、结实且对称，典型的前牙/侧牙
保存状况：极好——牙釉质保存良好，牙冠沿线清晰可见的竖向条纹
根部与 bourlette：自然保留，原始沉积基质仍附着
齿坡/齿缘：超细且沿切缘（刀齿）保存完好
状态：就这个年代的化石而言，极为出色
收藏者关注点：视觉上令人印象深刻，适合化石收藏爱好者、古生物学爱好者，或作为高档装饰陈列品。
Otodus megalodon (whose species name megalodon derives from Greek meaning “big tooth”), commonly known as the megalodon, was an extinct species of giant shark that lived from the Early Miocene to the Early Pliocene, approximately 23–3.6 million years ago (Aquitanian–Zanclean). Its large fossil teeth demonstrate that it had a cosmopolitan worldwide distribution.
In the past, O. megalodon was believed to belong to the family Lamnidae and to be closely related to the great white shark, Carcharodon carcharias. However, later studies reclassified it within the extinct family Otodontidae, which diverged from the great white shark lineage during the Early Cretaceous period.
Estimates of megalodon size vary depending on the reconstruction method used, with maximum total length projections ranging from approximately 14.2 to 20.3 meters.
