A tropical species turns up in what was once a surprisingly cold region. A land animal appears on an island separated from the mainland by an ocean. A familiar species is found in rocks that suggest an environment completely unlike the one its living relatives inhabit.

Continents moved. Seas appeared and disappeared. Land bridges formed and vanished. Ice sheets expanded. Deserts became grasslands, and forests spread across regions that are now frozen or barren. Coastlines also migrated by hundreds of kilometr...

It had three eyes. The animal had the normal pair of eyes on either side of its head, but between them, positioned in the centre of its forehead, w...
