Researchers dug up two fossils belonging to ancient, flappy, and snouted arthropod relatives from what's now a sheep field near Llandrindod Wells in Wales.
Dinocaridida are thought to have descended from the same shared 'parent' group of animals to deuteropods, ancient arthropods that gave rise to classifications that would include spiders, insects, and crustaceans.
University of Cambridge paleontologist Stephen Pates and colleagues named the largest of the newly described animals, but have yet to classify the smaller one as they're uncertain if it's a different species or a younger form of the other. , and all had similar 'legs', but the new finds also had snouts – proboscises – with features seen in radiodonta.and friend could be more related to either group. If they are part of the opabiniids, these fossils extend this group's known existence on Earth by 40 million years.
The fate of the first two head appendages is of particular interest because they have provided these scuttling life forms the ability to occupy so many different roles on Earth, from filter feeding to apex predators. So researchers credit them for the unmatched success of arthropods on Earth.
