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.

And even if t.rex got to the skull which is very unlikely he would still need to pass bony EYELIDS now if Ankylo is that well protected I find it hard to see why people are saying t.rex could kill ankylosaurus with a bite to the head.

Trex has quite powerful bite force as it is fully capable to crush an ankylo's skull, regardless of armoured eyelids. Also the neck isn't fully armoured.

Tyrannosaurus would NOT beat this beast easily. See t.rex is getting overrated again. Ankylo is a walking tank. I know t.rex had a strong bite but do you really expect him to bite through that armour? And even if he could do you think ankylosaurus will let t.rex happily bite through his armour when he has a club at the end of his tail? And the only soft spot on the ankylo is his belly and t.rex certainly couldn't flip ankylo with those arms. So all in all ankylo would win 8/10
Actually, Ankylosaurus is more overrated than Tyrannosaurus.

The moment Rex bends down for the fatal bite, Rex no longer has half a skull.

I think both Ankylosaurus and T.rex are very highly, inflated overrated. Based on the size-comparision T.rex should have the edge, but in reality the bones of many large Tyrannosaurs showed al-mighty blows to their leg-bones and this might had very well be due to the tail-club of an ankylosaurus. Theropod lower leg bones, shinebones are also quite so thin and evidently the club-tail of ankylosaurus was mostly hitted there (sekvence 0:33- 2:00)


I accually belive a smaller more agile predator with better mobility and intelligence would had been better at dealing with ankylosaurus then larger, less agile predators, with little mobilty and lower intelligence.

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.

While bitting on the skull is certainly a good idea, T.rex wasn´t smart enough to make a frontal attack. Infact all of the documentaries depict T.rex as attacking from the back or at sides, which are just in the range of Ankylosaurus tail-club. As I said before a smaller, more agile predator with better mobility and higher intelligence would have done the job better.

I don't think the size chart is very accurate. I'm pretty sure Ankylosaurus was bigger. And I think it would be hard for the Rex to kill it because it was really well armored. But the Rex does have the size advantage. I'll say 50/50 for now.

I dont understand how you think size will help. to me thats a disadvantage i mean if its tall it cant sink those chompers into the belly can it? Can someone please explain why size would help.

Well Trex has proven to survived a blow of the tail club so it won't be death for Trex. Sue survived the blow.

Who said that Sue was an exceptionally larger Trex? I don't see any evidence that she was an exceptional specimen.

Oh, come on. It's Anky! Anky just f**ks up one T.rex after another! Anky wins 95% of the time. T.rex will not be able to dodge a blow. And once you're hit, you're gonna get hit again, and again, and again, and again!
