An article published in the journal “Current Biology” describes a research on a species of reptile that was called Triopticus primus. A group of paleontologists led by Michelle Stocker of Virginia Tech College of Science studied this reptile that lived about 230 million years ago, noting several features similar to those of pachycephalosaur dinosaurs that lived 100 million years later. The research also revealed other similarities between animals contemporary to Triopticus primus and dinosaurs that lived millions of years later.
