Researchers have found a 380-million-year-old coronary heart preserved inside a fossilized prehistoric fish.

They say the specimen captures a key second in the evolution of a blood-pumping organ shared by all vertebrates, together with people.

The coronary heart belonged to an extinct fish often known as the Gogo.

The discovery, described as “dizzying”, printed in the journal Science, was made in Western Australia.
