An article published in the journal “Science Advances” reports an analysis of fossils of Namacalathus hermanastes, an organism that lived in the Ediacaran period. A team of researchers subjected exceptionally preserved fossils dating back approximately 547 million years to a sophisticated X-ray tomographic examination. This also allowed fossilized soft tissue to be found for the first time in this species. The details of the two specimens examined led to the discovery of the link between animals that lived in the so-called Cambrian explosion and one of their ancestors.
