• Information on hypothesized reproduction, if known, eggs and/or juveniles would be nice.

• Information on its feeding strategy needs to be updated. Specifically, the scavenger vs. predator debate. While it may have hunted prey, one of its main food sources most likely was in fact carrion. It probably used its highly developed sense of smell to detect fresh kills made by smaller predators and then showed up on the scene to scare them away. After fighting with the smaller predators and/or scaring them away it probably took what was left of the kill. Even if it could run as fast as certain herbivores, they would have started running as soon as they saw or smelled the t-rex, so it would have been difficult to catch any but the old, the juvenile, the sick and the weak. It's more likely that the t-rex ran when it needed to make it to a fresh kill before the predators who actually made the kill could finish it.
• The text refs for the books need to be IDed somehow, perhaps in parenthesis.
• Improve Tyrannosaurus in popular culture and summarise main points here.
• Figure out status of the image Image:Sue'sBrain.jpg.
• Don't reference to Jurassic (movie). (I'm not sure what this means, however wrong the name of the movie is it does portray a T-rex well....?)
• Need an image of a T-rex as if feathered. (I have emailed Ken Carpenter and Thomsa Holtz for leads...Cas Liber 01:59, 20 June 2006 (UTC)) - getting there - Ken told me of an image in Nov 99 National Geographic so I will email them forthwith Cas Liber 12:44, 21 June 2006 (UTC) I had the issue in question but I seem to have misplaced it. I wasn't aware images from NatGeo were usable here--if so, I've got a ton of scanning to do... At any rate it might be better to ask around to amature paleoartists, browse through the artists on Dinosauricon, etc. There are plenty of great feathered rex illustrations out there.Dinoguy2 21:59, 13 September 2006 (UTC)
• Mapping a timeline of geological and evolutionary history to Galactic rotation is linear (though cyclic because of the rotation) and profitable. For instance, T. Rex emerged just after the Andromeda Galaxy lined up with the Galactic Center. The Cambrian was three Galactic rotations ago, plants emerged onto land two, and animals about one.

• Replace the dino cards references with reliable sources that have a url or isbn
• Include the word 'partially' in description of Soft Tissue section where it reads fossilized leg bone. Clearly if this contains soft tissue the specimen was only partially fossilized.

Sorry, I think you misunderstand fossilization. Fossils are hard (they're rocks), but they sometimes preserve soft tissues by turning them into hard material, see for example Burgess Shale or Cambrian explosion. Philcha (talk) 00:16, 1 March 2008 (UTC)

Philcha, while most fossils are indeed rock (and may be completely remineralised) "fossils" can be any buried trace of life (except human artifacts), although some definitions do draw the line at the end of the last glacial episode 10,000 years ago - anything more recent is then not a fossil (cf Concise Oxford Dictionary of Earth Sciences). The soft tissue being referred to here is possibly unremineralised connective tissue including proteins (collagen) and amino acids. The T rex was certainly fossilised in the strict sense, but amazingly may retain tiny amounts of original unmineralised tissue - this is what "only partially fossilised" intends here, I believe. It would probably be better to say the fossil apparently includes original connective tissue. This has also been reported in a Hadrosaur.Orbitalforam (talk) 09:32, 18 February 2010 (UTC)

The part about speed needs to be fixed. In order for a Tyrannosaurus to run at 45mph it would need massive legs muscles. The size of the muscles it needed for that kind of speed would be too heavy for it to lift. In comparison, the leg muscles it did have were already heavy enough, so that the combined wieght of the leg muscles and the body forced it to walk straight legged, like an elephant. So much leg muscle would also mean that some muscle would have to actually be taken away from the jaws to add to that(A creature can only have so much muscle in it before it becomes to heavy to move itself). Also that type of speed would be dangerous for a Tyrannosaurus. The skull of T-rex was extremely heavy, and those arms could not support its weight at all, so one fall could be fatal for it. Therefor the Tyrannosaurus could only run at about 15-20 mph. Sorry, I just had to get that out.:) Watch out for the Discovery ChannelMs. dino fanatic (talk) 02:02, 2 March 2008 (UTC) show "Tyrannosaurus- New Science: New Beast". That's where I get all of this from.
