Tyrannosaurus rex
Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the upper Cretaceous Period, 67 to 65.5 million years ago. It was among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it was the largest known tyrannosaurid and one of the largest known land predators. By far the largest carnivore in its environment, Tyrannosaurus rex may have been an apex predator, preying upon hadrosaurs and ceratopsians, although some experts have suggested it was primarily a scavenger. The debate over Tyrannosaurus as apex predator or scavenger is among the longest running in paleontology. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR2081 ("Sue"), measured 12.8 metres (42 ft) long, and was 4.0 metres (13.1 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons). Packard et al. (2009) tested dinosaur mass estimation procedures on elephants and concluded that dinosaur estimations are flawed and produce over-estimations; thus, the weight of Tyrannosaurus could be much less than usually estimated. Other estimations have concluded that the largest known Tyrannosaurus specimens had a weight exceeding 9 tonnes.

Ankylosaurus magniventris
Ankylosaurus is a genus of ankylosaurid dinosaur, containing one species, A. magniventris. Fossils of Ankylosaurus are found in geologic formations dating to the very end of the Cretaceous Period (about 66.5–65.5 Ma ago) in western North America. Although a complete skeleton has not been discovered and several other dinosaurs are represented by more extensive fossil material, Ankylosaurus is often considered the archetypal armored dinosaur. Other ankylosaurids shared its well-known features—the heavily-armored body and massive bony tail club—but Ankylosaurus was the largest known member of the family. In comparison with modern land animals the adult Ankylosaurus was very large. Some scientists have estimated a length of 9 meters (30 ft). Another reconstruction suggests a significantly smaller size, at 6.25 m (20.5 ft) long, up to 1.5 m (5 ft) wide and about 1.7 m (5.5 ft) high at the hip. Ankylosaurus may have weighed over 6,000 kilograms (13,000 lb), making it one of the heaviest armored dinosaurs yet discovered. The body shape was low-slung and quite wide. It was quadrupedal, with the hind limbs longer than the forelimbs. Although its feet are still unknown, comparisons with other ankylosaurids suggest Ankylosaurus probably had five toes on each foot. The skull was low and triangular in shape, wider than it was long. The largest known skull measures 64.5 centimeters (25 in) long and 74.5 cm (29 in) wide.

Blue whale is king of all animals lol.
Actually not, it's Amphicoelias...

Carpenter made a mistake, he reconstructed the vertebra of Diplodocus carnegii too tall. He reconstructed it at 122 cm tall, when in reality it was between 90-100 cm tall. That would yield a sauropod larger than a blue whale...

Ask Fragillimus335 for more info, as he was the one who gave this info....

Sauropod is not the king either, human is the king !. Blue whale has almost gone extinct because of human hunting

Tell me which animal but human have the power to create this

Bye bye Sauropods worshipers

Try pitting a human, ANY human, against a sauropod one-on-one, and the sauropod would dominate in seconds

Pitting an army against one sauropod is not fair

Nuke.
I hate that excuse...

You seriously think that a single human can carry a nuke? Nuclear weapons are very heavy!!!

The nuclear bomb "Little Boy" had a mass of 4.4 tonnes!!! And it was a relatively weak and small compared to other nuclear weapons!!!

Let's just get back on topic...

Of course, an animal that would surely die if it falls is the king.

You must take so seriously, even though this is joke. Holy father trucking poop!
After seeing so many pathetic stupid fanboyish comments on yt, the line between joke and serious answer seems to have blurred for me...
Me too. Anyways, can the bit of the Tyrannosaurus crush the armor of an ankylosaur? In The Truth About Killer Dinosaurs, they had a mechanical T.rex skull and it crushed a car. Can it crush Anky's armor?

It doesn't need to bite, it can just use it's size to crush the Ankylosaurus' innards...

IMO - the Tyrant King has the size, strength, and weight advantage. So I would say it should be at least a 60-40 split in favor of the Rex.

How relevant is it to think about contemporary matches between animals that may play similar roles to the Tyrannosaurus Rex and the Ankylosaurus?

For example, the African crested porcupine is similarly smaller than lions, but does - in some circumstances at least - hold it own very well against them.

(See http://www.youtube.com/watch?v=_r2rDBVFAv4.)

Thank you,

Newbosaurus & Sonosaurus

^true, but I don't think a porcupines spikes are comparable to those of Ankylosaurus, the latter having far shorter ones that will not bother a T. rex that much.

I think I would favor over tyrannosaur over an ankylosaur even at parity because of this tidbit of info.

Quote:
 
These herbivores were up to ten meters long, with a tail ending in a huge bony club - 'probably used as a weapon', says Torsten Scheyer, 'even though they definitely could not simply swing it back and forth; the whole construction was simply too stiff for that.'


http://carnivoraforum.com/topic/9806084/1/#new Go to broly's 2nd post.

If I read that correctly and the information proves to be accurate ankylosaurus's club tail was far less effective than it has been portrayed, coupled with the fact that the ankylosaur would be incredibly ungainly and probably have low stamina and I think a cautious tyrannosaur would prevail over the club tailed dinosaur more often than not at similar sizes.

For this match up however tyrannosaurus destroys ankylosaurus because of the huge size disparity.

As I was re-reading the Carpenter paper on Anky, I found that the 6.25 meter estimate was for the holotype specimen. The largest specimen is known from a skull roughly 25-30% larger than the holotypes. That brings the largest Ankylosaurus back up into the 8 meter range. (And about 4-6 tons) Still too small to effectively kill a Tyrannosaurus though.

The moment Rex bends down for the fatal bite, Rex no longer has half a skull.
Ankylosaurus was a slow animal, so Tyrannosaurus wouldn't have big trouble to avoid the tail club.
Tyrannosaurus can trample ankylosaurus, and then bite it and crush its skull, or bite the skull Directly.
If the t rex tried to avoid the club the anky would simply turn its rear facing the t rex
