Re: ceratopsian forelimbs and the galloping question

I saw a documentary recently that discussed the controversy over the front
legs of ceratopsians. As I understand it, a new articulated specimen was
discovered that revealed the true placement of the legs and it showed that
horned dinosaurs could indeed gallop. Is this the case? If anybody has
firsthand info I would be pleased to see it.

Recently I saw a ceratopsian specimen at the Canadian Museum of Nature (unfortunately, I do not feel that it is right for me to go into details about this specimen. Doing so could lead to conflict with a researcher who I do consider to be my friend). The specimen was still in its matrix at the time and its posture suggested a sprawling configuration.

I believe I saw the same documentary and that _Triceratops_ specimen appeared to be laying on its side. So, if the animal did have a sprawling configuration to its legs, and it were lying on its side, when the flesh then decayed, it is likely that the humeri would be forced to rotate under the body.

I don't pretend to be a trained (and experienced) paleontologist, but from what I have seen, I don't think that the posture of the fossil animal as it appears in its matrix is all that indicative of its posture in life.

All the best,
