Fighting Dinosaurs
`Amongst all the fossils ever found in the world, there might be nothing more bizarre than this specimen. One Protoceratops, a herbivorous (plant-eating) dinosaur, perished in the struggle with a carnivorous theropod, Velociraptor. After their death 80 million years ago, both skeletons were fossilized, then finally unearthed in 1971 in fully articulated forms without having been smashed.
The reason why they fought with each other is not known. Protoceratops might have been defending its nest from the predator, or the two creatures might have encountered accidentally, but all we can do is build speculations and guesses about them.’
