Ichthyosaur's 250m year old meal it's last

In 2010 paleontologists digging in a quarry in southwestern China made a rare discovery. The ichthyosaur's stomach they found contained the undigested remains of a thalattosaur. Researchers speculate that a violent confrontation took place, one which caused the ichthyosaur to fracture it's neck, killing it as it consumed it's prey. These events took place sometime after the end of the Permian era, some 250 million years ago, when land vertebrates started moving back to the sea following a mass extinction event.
