Looks like when we had "walking with dinosaurs" here. Poor guy in the suit wasn't acclimated to the altitude during the demo, almost keeled over.
(Paleontologist hat on) Also, your average Velociraptor was about 3 feet tall and maybe 6 feet long (nearly half of that was tail). Critter is a bit of an exaggeration. In reality it'd be like getting attacked by a coyote (or a dingo to you wacky Victorians).
