Medical scanner reveals dino heart

The first ever fossilised dinosaur heart has been discovered by scientists in the US. It was found in the remains of a 66 million-year-old creature dug up in South Dakota. The researchers used a computer tomography (CT) scanner to investigate the organ. The study shows the dinosaur, nicknamed "Willo", to have a four-chambered heart more akin to a human or a bird than a lizard.
