BBCnews is carrying this summary of recent discoveries made about sauropods, the big "brontosaurid" beasties of the Jurassic. By inputting the data for one of these critters into a floatation simulation originally meant for crocodiles, it was discovered these gargantuan animals would actually float. Well, sort of. It's not clear if they would have been stable.

Not exactly earth-shaking (as it were). These creatures were originally thought to be almost completely aquatic, but that theory fell out of favor when it was realized deep water would prevent them from breathing. Also, more modern fossil finds show the sauropods lived in a variety of places, from shorelines to deserts. Still, it does help explain some weird "tippy-toe" pathways that have been found over the years.
