Protoceratops and ancient griffin art.jpg (IMAGE) University of Portsmouth Caption Comparisons between the skeleton of Protoceratops and ancient griffin art. The griffins are all very obviously based on big cats, from their musculature and long, flexible tails to the manes (indicated by coiled “hair” on the neck), and birds, and differ from Protoceratops in virtually all measures of proportion and form.
