Even more surprising, he talks to the class about a new species of hairy Elephantidae only recently the Rock Mammoth. This proud ancestor of the hairy musicians of the ’70s didn’t actually disappear. In fact, these elephants had had enough of being rock stars and wished for a more tranquil life. So they decided to remain hidden during the last millennia. But now Louis, the great mammoth enthusiast and rigorous scientific apprentice, has discovered this well-kept secret and is ready to reveal it to the world.
