A team led by Egyptian scientists have dug up a 43 million-year-old fossil in the Sahara Desert in Egypt of a now-extinct amphibious four-legged whale. These walking whales had a strong raptorial feeding style. It was likely a top predator at the time, similar to what a killer whale is today.

由埃及科学家带领的一个小组在埃及的撒哈拉沙漠中挖出了一个4300万年前的化石，是一种现已灭绝的两栖四脚鲸。这些会走路的鲸鱼拥有猛兽式的捕食方式。它在当时可能是一个顶级的捕食者，类似于今天的逆戟鲸。
