It’s not often that a new species of abelisaurid dinosaur gets discovered – the habitat of the famous Carnotaurus hasn’t yielded another abelisaurid since it was found 40 years ago – but that’s exactly what a CUHK-led team has just done. The extensive set of bones they found in South America come from Koleken inakayali, an agile apex predator that inhabited the ancient southern supercontinent of Gondwana 60-plus million years ago. The discovery sheds light on how predatory dinosaurs evolved and shows that more than one top predator lived side by side in Late Cretaceous ecosystems.
