China has always been a paradise for fossil enthusiasts. A team of Chinese and Canadian paleontologists made a particularly spectacular find not far from Lujiatun in the northeastern Chinese province of Liaoning. The researchers led by Gang Han of Hainan Tropical Ocean University conclude in the journal Scientific Reports that the twisted pile of bones is a mammal wedged in battle and a dinosaur. What is particularly astonishing is that the mammal obviously has the upper hand in the fight against the three times heavier dinosaur. The fight over life and death was ultimately interrupted by a volcanic eruption, which preserved the bones of the two primordial animals in a mudslide of volcanic ash and water.
