It has also been suggested - originally many years ago - that T rex and other large theropods were principally ambush hunters, for which a good sense of smell and/or night vision would certainly not be disadvantageous. So like modern leopards or komodo dragons, they just found a bit of cover next to a well-used trail, hid, and waited ...  and then when some suitable prey passed, all that was needed was a short burst of speed and a quick killing bite, or even just a disabling bite. No great stamina for the chase, nor speedy ability to outrun the prey, was ever needed as it all depended on the sudden lunge and devastating bite. And you cannot deny that T rex was apparently capable of a quick, very powerful bite. Modern komodo dragons are easily outrun by adult humans if pitted in a straight race, yet komodo dragons regularly catch and kill flighty animals like wild deer, goats, pigs and wild fowl ... and indeed sometimes even humans.

Meles meles,

occasionally wanted to post yesterday something about the T-Rex for Triceratops. Just seen on BBC World:

Kind regards to both from Paul.

I've let my BBC membership lapse. Can't play it.

Thanks none the less, Ferval.
