In a 380-million-year-old 'beautifully preserved' fossil of an ancient jawed fish, the world's oldest heart has been discovered. The heart was discovered by scientists from Curtin University along with a separate fossilized stomach, intestine, and liver, with the organs in a similar manner to modern shark anatomy. The team hopes that the finding will help to shed some light on the human body's evolutionary evolution.
