Fossil of <i>Tamisiocaris borealis</i> (IMAGE) University of Bristol Caption This is one of the fossil feeding appendages of Tamisiocaris borealis, an anomalocarid that lived 520 million years ago during the Early Cambrian. A new study of Tamisiocaris fossils discovered in northern Greenland has found that these ancient marine animals used bizarre facial appendages to filter food from the ocean. The research, led by the University of Bristol, UK, is published this week in Nature.
