A 3-ton dino from the Jurassic period was capable of shrugging off most massive traumas, LiveScience reports. Using high-tech imagining technology, researchers at the University of Manchester analyzed the cracks, fractures, and breaks in the fossils of the carnivorous Allosaurus fragilis. X-rays revealed a multitude of severe injuries, all healed, and small chemical differences between mended and normal bones. The findings, which will be published today in the Journal of the Royal Society Interface, hint at the chemistry behind the dinosaur’s bone repair.
