back on topic,
I personaly think T-Rex was both a predator and a scavanger (it would only scavange if it realy needs too). I don't get why horner is saying it was only a scavanger. something about its small arms and the femur being longer then the tibia, or somthing like that. but my argument is that the Metatarsals would compensate for the short tibia. (if you can get used to standing on your toes then your complete foot, you'll notice you can go a little faster then usual) I mean, until we can either clone a purely genetic copy of a Tyrannosaurus or we build a time machine to find out for ourselfs when we get chased by it, I'm gonna stick by with it being Both a hunter, and a scavanger.
btw, isn't a chicken the closest reletive to a T-Rex? or was that proven wrong?
