Only quadrupeds with arms at least almost as strong as the legs can gallop
because during part of the cycle the arms alone are bearing load. If the
arms are too slender to bear such high loads, as per hadrosaurs, then they can
only be used as auxiliary power (adding maybe 10-20%) with the legs bearing
most but not all of the load during a trot or pace. No person actually
researching hadrosaur locomtion has every proposed galloping in the technical
literature, and unless that happens no animator should violate scientific
methodology and show it.
Elephants can only amble, and cannot exceed 15 mph (measured from frequent
races in Asia and recent studies of elephant locomotion). Same for
There are a fair number of skin samples from a variety of sauropods and
they all follow the typical dinosaur pattern. Animators should always stick to
what is known when it is known, and not engage in speculation that can
mislead audiences. The animators were probably just being lazy and did not do

how do you propose they use their arms to add speed, if you are arguing
that they didn't put their weight on their arms?

Elephants can move pretty fast.

Skin from the same Genera or Family of sauropod? Its possible that
sauropod skin was as diverse as, say the skin of mammals, yes?
