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. |

The Chicago River is the only river in the world that flows backwards. Due to sanitation reasons, engineers used a reversal technique to divert sewage away from Lake Michigan’s water supply. |

The biggest mammals that escaped the global die-off weighed no more than a pound. But just 100,000 years later, the largest species among their descendants were about 13 pounds, as heavy as a modern raccoon. And another 200,000 years later, “the largest mammals had again tripled in weight, to about 45 pounds,” Lyson says. That’s about as heavy as an American beaver, and much heavier than any pre-extinction mammals. |
