Prehistoric marine reptile fossil has embryo inside – Polycotylus latippinus is a marine reptile which lived about 78 million years ago. The fossil, which is 15.4' (4.7 m) long, has an embryonic skeleton inside, including little ribs, 20 vertebrae, shoulders, hips and paddle bones, resolving the mystery of its reproduction (live birth). Scientists had long thought the creature was not built to crawl on land to lay eggs, but there was no evidence to support the theory
