That's the point I am trying to make. Ceratopians purposely evolved sprawling
forelimbs to better cope with the paleenvironment of the Gobi (an arid
environment with many dune fields). When one considers how effective the
ceratopian body plan was for efficent movement in the dunes, it makes perfect
sense why they would evolve sprawling forelimbs, while leaving the hindlimbs
vertical. The dinosaurian equivalent of the dune buggy, if it were.
