A 375 million-year-old fossil of a fish-like creature with features of both fish and four-legged animals. It has a crocodile-like head, sharp teeth, and a neck that allowed it to lift its head out of the water. Its fins had bones similar to those of a tetrapod, and its front fins could have been used for support on land.
