The carcass of a large long-necked dinosaur in the Junggar Basin in northwestern China served as food for several other dinosaurs, Tübingen paleontologists say, citing tooth marks on the bones and several dinosaur teeth, which matched the tooth marks perfectly. A research team from the Geoscience Department at the University of Tübingen found that the large number of bite marks on the 20-meter carcass showed that other animals fed on it for a long period of time. The bones and teeth were preserved in situ by favorable climatic and geological conditions for more than 160 million years. For the paleontologists this is a rare stroke of luck, as little is known about the feeding behavior of large predatory dinosaurs. The team’s study has been published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.
