Steppe Rhinoceros - Elasmotherium caucasicum
Elasmotherium ("Thin Plate Beast") is an extinct genus of giant rhinoceros endemic to Eurasia during the Late Pliocene through the Pleistocene, documented from 2.6 mya to as late as 50,000 years ago, possibly later, in the Late Pleistocene, an approximate span of slightly less than 2.6 million years. Three species are recognised. The best known, E. sibiricum was the size of a mammoth and is thought to have borne a large, thick horn on its forehead which was used for defense, attracting mates, driving away competitors, sweeping snow from the grass in winter and digging for water and plant roots. Like all rhinoceroses, elasmotheres were herbivorous. Unlike any others, its high-crowned molars were ever-growing. Its legs were longer than those of other rhinos and were designed for galloping, giving it a horse-like gait. The Russian paleontologists of the 19th century who discovered and named the initial fossils were influenced by ancient legends of a huge unicorn roaming the steppes of Siberia. To date no evidence either contradicts or confirms the possibility that Elasmotherium survived into legendary times. The most reconstructed species is perhaps E. sibiricum by generations of scientists working at the Paleontological Museum in Moscow and elsewhere in Russia. The majority of the fossils fall or have fallen within their national jurisdiction. The dimensions and morphology of the various reconstructions vary considerably. They are for the most part estimating the gross details from the minutiae. However, they all agree on the general order of magnitude, that sibiricum was comparable to a Mammoth and was rather larger than the contemporary Woolly Rhinoceros. E. sibiricum had a measured shoulder height of approximately 2 metres (6.6 ft). To it, however, must be added the height of a massive hump anchored on the fin-like transverse processes extending from the top of the cervical vertebrae, a maximum of 53 centimetres (1.74 ft). The total height then was in excess of 253 centimetres (8.30 ft). The measured length of sibiricum (from a nearly complete skeleton found at Gaevskaya) is 4.5 metres (15 ft). Extrapolation from the greater size of caucasicum molars obtains a length of 5 metres (16 ft)—5.2 metres (17 ft) for caucasicum. According to Legendre's formula, E. sibiricum had a mass of over 4,000 kilograms (3.9 long tons; 4.4 short tons); E. caucasicum, 5,000 kilograms (4.9 long tons; 5.5 short tons). These weights place Elasmotherium in the "really huge" category of all Rhinocerotidae and therefore the animal was "strongly brachyopodial;" that is, they required feet of large contact area to prevent sinking into the soil. The feet were unguligrade, the front larger than the rear: purely tridactyl on Digits II-IV in the rear, but with an extra vestigial digit, I, in the front.

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.

I think T-Rex would win in my opinion. Though the Rhino would win at times as well.

T-Rex was capable of tackling horned, quadrupled prey and while Elasmotherium was pretty tough beast, it seems to me T-Rex would find it easier than the ceratopsians it was accustomed to.

70/30 in favour of T-Rex.

T.Rex would not have tackled a Triceratops in a head to head and one on one.

Holtz believed a T.Rex would lose to a Triceratops more often than not--which should make sense, predators fail more than they succeed.

Not only that, advanced simulation engines like 'Be the Dinosaur' have shown us that it would be very difficult for a T.Rex to attack a Triceratops due to the latter's superior pivoting ability, as T.Rex would have gone for the flanks to avoid the head.

The Steppe Rhinoceros isn't quite as large as the Triceratops, but its horn is reconstructed as much larger than the Trike's horns. And it was likely more agile as well.

If the T.Rex comes in head to head, its neck or stomach is getting gored. There will be no avoiding this.

Elasmotherium should take the majority over any theropod.

Elasmotherium wins IMO
This isn't Triceratops, this is Elasmotherium. Elasmotherium was much more agile than Triceratops and it was much smarter.
Tyrannosaurus Rex doesn't have a size advantage, so why it would win?
And most members voted for the Giant Rhinoceros against a 13,000kg Spinosaurus, why can't the rhino win against a 8,000kg Tyrannosaurus?

The T.Rex could theoretically get a horn through its throat if it comes in head to head, going by the scale.

If T-rex decided to be suicidal and charge head-on then Elasmotherium would win 99% of the time. I doubt that though, rex would most defintely attack the flanks which would prove difficult. However the steppe rhino would absolutely flip if he was attacked by rex, he has never faced a predator that huge. He'd would probably prefer to retreat but as rex wouldn't let him, he'd be forced to fight sooner or later. Now rex probably did take ceratopsians quite frequently, but I'm guessing that like most predators that eat formidible prey, he went after young, injured, old, and sick individuals. Now if this particular steppe rhino is a healthy male in his prime, then I'm seeing a close win for the rhino, about 60-65%.

A well posed thought.

We often forget about plausible behavior and focus simply on anatomy.

The T.Rex was accustomed to dealing with armed herbivores. It would probably be able to win.

It was accustomed to hunting them, not fighting them.

And the ones he hunted had horns much smaller than Elasmotherium is reconstructed to have.

The latest estimate mass about Sue is 9500 kg. Elasmotherium is less massive than T-rex, so it's strange that people favor a smaller herbivorous against a bigger carnivorous.
Would you favor a warthog against a lioness?

I just wanted to say that Tyrannosaurs like other Theropods had bones in the belly region. These could possibly protect them from being stabbed by the eleasmotherium.
