In Depth

       Eardasaurus is a‭ ‬genus of pliosaur known to‭ ‬have lived around European waters during the Middle Jurassic.‭ ‬The skull of Eardasaurus displays some proportional features that are similar to the famous Liopleurodon,‭ ‬including‭ ‬a diastema where the premaxilla meets the maxilla.‭ ‬However the skull of Eardasaurus suggests that as many as thirty-four to thirty-five teeth may have been present across the skull tooth bearing bones,‭ ‬almost double the number of teeth present in Liopleurodon.‭ ‬The preserved teeth in Eardasaurus also have traces of what appears to have been enamelled cutting edges in life.
