Paleontologists have described the first three-dimensional preservation of soft tissue in Namacalathus hermanastes, a skeletal metazoan (multicellular animal) that lived some 547 million years ago (Ediacaran period) in what is now Namibia, and established a strong evolutionary link between Ediacaran and early Cambrian metazoans. Namacalathus (individuals numbered). Centimeter scale. Image …
