An amazing recent fossil discovery: a whole school of fish! A single slab of limestone from the Green River Formation in North America contained 259 fish of the extinct Erismatopterus levatus species. They lived between 56 to 34 million years ago.

The discovery is exciting because it is a rare case of fossils demonstrating behavior – in this case, that fish have gathered into shoals for millions of years.
