Predator vs scavenger
- much as modern-day lions often take the kills of hyenas and other smaller predators.
This example is not good since it's usually the hyenas who steal from the lions.
http://www.wildwatch.com/resources/mammals/lions.asp and http://www.geocities.com/lions_of_safrica/scavenger.htm say otherwise. Actually, the theft ratio is highest for lions stealing from cheetahs and leopards. --user:Belltower
OK, I'll agree that both lions and hyenas are thieves of each other, but it's not clear which does most. There's no doubt that both will steal from the smaller cats. Eclecticology
What real difference does it make if Tyrannosaures Rex stole kills from other animals. Yes a lion my steal a kill from time to time but the bulk of their diet and indeed their morphology is exquisitely suited for bringing down prey. The same can be said of T. Rex
Most predators of which I am aware are not above stooping to eat someone else's kill if it is readily available
What other pictures of parts of the T Rex to upload. I have the front arms/claws, the feet, the backbone and tail, and more (bigger) pictures of the skull. Any bigger pictures of the skull will show the armature which is holding up the fossil bones. Any requests? As you can see, the Field Museum has the holiday decorations up. I can't get rid of those til later, and it will take a trip to Chicago to get more pictures. There are pictures with people in them to get an idea of the size. Also, I have to shrink the images because they can be huge. Is there a use for the huge pictures. Ancheta Wis 01:24, 23 Jan 2004 (UTC)
Doubts about T. rex?
I was watching a discovery program which questioned the widely held belief that T. Rex was a mighty predator. As evidence the small useless arms, the ratio of its leg bones (making it a slow runner) and poor vision is presented. This combined with good smelling leads paleontolgist Jack Horner to think that T. rex was not a predator but instead a scavenger. Has anyone heard about this, do the ideas have any support in the science community, and could someone write a section about it?
A google search turns up a few interesting hits[1].
This image, taken at the Field Museum of Natural History, shows the size of the right arm. Bear in mind that the arms of this T. rex are as large as a man's arms, and that T.rex could definitely do damage with them. Note the claws; they are as large as a man's hand.

Images and templates
At Polish Wikipedia there are some images, that ilustrate everything about T. rex. That's all my pictures you can download them, they are under GFDL license. I prepare them for international use so there are, no texts on images (generaly, when I could do that).
The word is: Tyranozaur.
I can cooperate with exchanging infos and images about dinos (write any questions on my discusion page in English).
- You can make comparisons between human and dinos using my templates, at Media Wiki- Commons there are more informations, images plased at Commons are directly accessible at your language Wiki, like it was placed at your language Wiki file repository. But you must be sure that, file with the some name doesn't exist on your language Wiki file repository! -PioM
More predator vs. scavenger stuff
I don't have a reference for this on-hand, but I've heard it argued that the number of calories an animal as large as T. rex would require in order to survive would've prevented it from breing able to subsist on carcasses alone. In other words, it needed to eat too much and too often to just wait around for things to die.
I'm not a paleontologist, but I know enough to say with some certainty that the metabolism of T-Rex and dinosaurs in general can only be speculated in.
Another theory is that the tyrannosaurs as a group evolved in response to the enlarging, slower-moving and heavily armored prey animals that coincided with their own evolution. This parallel alone would, at least on the surface, seem to indicate predator-prey coevolution between the tyrannosaurs and the herbivores of their time. Under this hypothesis, the tyrannosaurs' "scavenger" adaptations actually served to help them prey on large, slow, well-armored prey such as the ankylosaurs, and so as a group they would not be expected to have evolved the features of smaller, more agile curosrial predators, but would have done fine with larger versions of otherwise scavenger-like features. Even vultures sometimes prey on defenseless and slow-moving animals, and when opposed by a tyrannosaur, very few contemporary species could've defended themselves adequately. A good solid bite from a Tyrannosaurus rex would probably be lethal to any land animal that ever existed, unless either heavily armored (allowing it more time to escape) or large enough to fight back and prevent recieving such a solid bite to begin with (such as Edmontosaurus and Triceratops) -- thus giving the animal some hope of surviving the encounter.
Wouldn't the large brain of Tyrannosaurus rex be a possible indicator of a scavenging lifestyle? Hominids were thought to have first begun evolving high intelligence while scavenging in the savannah, and Crows (also scavengers) are the most intelligent group of birds. It's also interesting to note that both Hominids and Crows are generalists, and many of the features of Tyrannosaurus rex seem adapted for any of a variety of functions, indicating that it too might have been a generalist (possibly leading to the theory above, that it would have to hunt and scavange in order to intake enough calories). --Corvun 09:42, Mar 5, 2005 (UTC)
Mary Higby Schweitzer
When one of us wikipedian get time, we need an article on Mary Higby Schweitzer. I thought she had to be really lucky from this article. [2]
Walking, running or hopping?
When dicussing the way the T-Rex walked, why is it that people always get the idea that the T-Rex walked or ran? Isn' it more likely that it hopped around, since it had legs, arms and a tail like a Kangoroo ? Maybe it even killed its pray by hopping on top of them? seriously - ever thought of that?
