A newly discovered dinosaur has small arms and a large head, similar to Tyrannosaurus rex. Estimated to have died at 50 years old, it’s also one of the oldest individual dinosaurs on record.
Two recent discoveries in Alberta and Uzbekistan have identified the top predators in those regions during the Cretaceous period. Fossils that had been in storage for years included the jawbones.
The lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.
Finding a fossil tooth embedded in bone is always great news for palaeontologists, as it is the gateway to some otherwise out-of-reach understanding of the behaviour of extinct animals.
66 million years ago, birds survived the calamity that wiped out all prehistoric dinosaurs. But could birds once again evolve into their long lost ancestors?
