An adult Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles known as plesiosaurs that lived during the Mesozoic Era, is shown giving birth in this publicity illustration released to Reuters August 12, 2011. A paper published in the journal Science Friday states that a fossil of the creature on display in Los Angeles with bones in its abdomen are evidence of a fetus, and that this species produced offspring through live birth.
