T rex is often depicted as more brawn than brains, but now scientists are hoping to probe just what was going on inside its head, drawing on findings from another kind of dinosaur: birds. Scientists have previously found some species of bird not only make and use tools, but are able to plan ahead and show basic forms of empathy – with laboratory tests suggesting emus can recognise other birds might have different experiences to themselves. Now researchers say they are hoping to explore whether there might be telltale hints of these capabilities in the skull, opening up the potential to probe the lived experience of dinosaurs like T rex. “We can’t put T rex through those tests,” said Prof Steve Brusatte, a palaeontologist at the University of Edinburgh.…
