Thanks to Fabrizio de Rossi for the excellent reconstruction(s) of…

How the Walrus Got Its Tusks

From PBS Eons. The rise and fall of ancient walruses, and how modern ones got their tusks, is a story that spans almost 20 million years. And while there are parts of the story that we’re still trying to figure out, it looks like tusks didn’t have anything to do with how or what these animals…
