("The fossil belongs to Fuxianhuia protensa, an extinct arthropod that lived in what is today Yunnan province in China during the Cambrian period, about 520 million years ago. 'This is the first preserved vascular system that we know of,' said Prof Nicholas Strausfeld from the University of Arizona")

My comment:
(a) I select this report because it displays a schematic graph of the arthropod. The heart in the "cardiovascular system" is the red tube on the back with a wider diameter than the rest of the vessels.
(b) The title of a report in the LA Times (which there is no need to read):
