But a sprawling mount does not match trackway data. If the forelimbs
had sprawled, the forefeet would have been far apart. If the forelimbs
had sprawled and the animal had brought its feet in under its body, the
forefeet would have been intoed. Neither of these is the case. The
animal's forelimbs did not sprawl (at least that's my interpretation).
