The fossil of the largest soft-shell egg on earth has been discovered in Antarctica, and it looks like it might have belonged to a distant ancestor of some of our reptile friends. Discovered in 2011 by scientists from Chile, and then shelved to research (as in Raiders of the Lost Ark) until recently, the fossil egg is the second largest egg of any known animal on the planet. Theories have been posited about how the reptilian parent (presumed to be something like a mosasaur) laid and maintained the egg(s). It's clear we have much to learn about the ancient development of our favorite scaly creatures! The full article may be found here.
