Fossil study reveals dinosaur was bit 200 million years ago
X-ray tomography of a dinosaur found in 1997 in China has revealed the giant herbivore was infected by a predator's bite around 200 million years ago. This is only the second known case of bone marrow infection in a four-legged sauropod dinosaur with the other belonging to a titanosaur from Argentina who suffered an infection in the spine, noted researchers.
