(University of Toronto) Paleontologists at the University of Toronto and the Royal Ontario Museum (ROM) have revisited a tiny yet fierce ancient sea creature called Habelia optata that has confounded scientists since it was discovered more than a century ago. Analysis of new fossil specimens suggest it was a close relative of the ancestor of all chelicerates, a sub-group of arthropods living today named for appendages called chelicerae in front of the mouth used to cut food.
