is a genus of pliosaur
known to have lived around European waters
during the Middle Jurassic. The skull of Eardasaurus
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
