Unlocking the Inner Lives of Dinosaurs Through Bird Skulls

The Lead

Scientists are now probing the inner lives of long-extinct dinosaurs like T rex by studying the skulls of birds, their direct descendants. This approach may provide clues about the behavior and cognitive abilities of these prehistoric creatures.

Exploring the Connection Between Birds and Dinosaurs

T rex is often depicted as more brawn than brains, but researchers are hoping to explore whether there might be telltale hints of advanced capabilities in the skull, opening up the potential to probe the lived experience of dinosaurs like T rex. Prof Steve Brusatte, a palaeontologist at the University of Edinburgh, is working with an international team of researchers to explore such possibilities.

The Science Behind the Study

“We can’t put T rex through those tests,” said Prof Steve Brusatte. “But if there are some distinctive features of the brain that maybe tell you with 95% confidence that the animal with that kind of brain is capable of that kind of behaviour today, then we can at least make predictions about these fossils.”

The Evolutionary Link

Birds are direct descendants of theropod dinosaurs and share many characteristics with them. In fact, a six-day-old quail embryo has a pelvis that looks just like the hips of a theropod like T rex. By studying the brains and behavior of birds, scientists can make educated guesses about the cognitive abilities of their dinosaur ancestors.

The Future of Dinosaur Research

While the approach may be a long shot, it could provide a new window into the lives of long-extinct creatures. As Brusatte notes, “Birds are survivors. They are adaptable, they evolve quickly, they change quickly.” By studying birds and their connection to dinosaurs, researchers can gain a deeper understanding of the evolution of life on Earth.
