Caption

Fossilized dinosaur heart. Coloured 3-dimensional computed tomography (CT) scan of the chest area of Willo, the first dinosaur with a fossilized heart. The fossilized structures (white) are embedded in the surrounding rock (yellow). The right scapula (collar bone) is the large bone running from upper left down to centre right. The white mass below it contains the heart, which is similar to those of mammals and birds. The sternum (breastbone) runs across lower centre. For this area in relation to the rest of the body, see image E446/383. Willo is a Thescelosaurus, a plant-eating dinosaur from 66 million years ago, discovered in the USA in 1993.
