Rat Grass

Newly discovered fossils have revealed that grasslands first appeared in South America, 15 million years before they appeared anywhere else. In other words, about 32 million years ago. Apart from one of the fossils being the oldest chinchilla found to-date, I'm not completely clear what the significance of the find really is. But they're scientists. They do cool stuff. That's good enough for me.
