The 372-million-year-old fossils of tetrapod -- creatures that evolved from fish living in water to creatures that walked on land -- have been discovered by researchers in Russia. And given how well they were preserved, we can tell this was one weird-looking creature.

Had humans been around at the time, they might have seen large, oval-shaped eyes hovering just above the water line looking back at them.

This tetrapod, dubbed Parmastega aelidae, looked similar to a crocodile, except its protruding eyes were on top of its head. Its nose and jaws, concealing a combination of sharp fangs on the upper jaw and needle-like teeth on the bottom jaw, would have been below the surface of the water, the researchers said. And the way they curved together looked a bit like a menacing grin.
