Paleontologists have discovered a 380-million-year-old heart – the oldest ever found – alongside a separate fossilized liver, stomach, and intestine in an ancient jawed fish, shedding new light on the evolution of our own bodies. Vital new evolutionary clues are provided by the research, which fo

Credit: Yasmine Phillips, Curtin University This research presents – for the very first time – the 3D model of a complex s-shaped heart in an arthrodire that is made up of two chambers with the smaller chamber sitting on top.Professor Trinajstic said these features were advanced in such early vertebrates. This offers a unique window into how the head and neck region began to change to accommodate jaws, which was a critical stage in the evolution of our own bodies.
Researchers used neutron beams and synchrotron x-rays to scan the specimens, still embedded in the limestone concretions, and constructed three-dimensional images of the soft tissues inside them based on the different densities of minerals deposited by the bacteria and the surrounding rock matrix. To accomplish this they enlisted the help of scientists at the Australian Nuclear Science and Technology Organization in Sydney and the European Synchrotron Radiation Facility in France.
