A prehistoric embryo was found still inside its mother. The 78 million year old fossil of a Polycotylus latippinus, which is a four flippered swimmer and classed as a reptile, was originally found back in 1987, on a Ranch in Logan County Kansas. Studies of this find are now complete and on display at the Natural History Museum of Los Angeles County.

This was a significant find, originally it was thought that this animal, being a reptile, laid eggs, but of course it is now known that the young were born live. Because this animal gave birth to young it is now thought that this prehistoric animal may have been “social” similar to a dolphin.
There is an article about this find in The Age.
