Together with an international team, Senckenberg scientist Hervé Bocherens studied the fossilized teeth of the carnivorous dinosaur Tarbosaurus bataar. Based on stable isotopes, the researchers were able to draw inferences regarding the habitat and feeding habits of this relative of T. rex, who lived around 70 million years ago. According to the results, the carnivores were not very picky in their prey selection. The study is published recently in the scientific journal Palaeogeography, Palaeoclimatology, Palaeoecology.
