The image displays the oldest representative of the cheloniellid arthropods.
A research team at the Geological Society of London studied fossils from the Lower Fezouata Formation in southern Morocco and discovered that animals typical of the Ordovician (485 and 443 million years ago) also existed during the Cambrian (541 to 485 million years ago).
