(University of Toronto) Paleontologists have uncovered a new fossil species that sheds light on the origin of mandibulates, the most abundant and diverse group of organisms on Earth, to which belong familiar animals such as flies, ants, crayfish and centipedes. Named Tokummia katalepsis by the researchers, the creature documents for the first time the anatomy of early mandibulates, a sub-group of arthropods with specialized appendages known as mandibles, used to grasp, crush and cut their food.
