Steppe Rhinoceros v Tyrannosaurus rex

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.

tyrannosaurus had a size advantage but the rhino has better weaponry. i say 50/50 with the slight edge going to tyrannosaurus.

I voted tarbosaurus over t-rex on another fight, so if tarbosaurus can do it t-rex can certainly do it.

There are 3 problems with that.

1.) Just because animal A can beat animal B and C doesn't mean Animal B can beat animal C. In this case, it is a little mixed up, but you should be able to get what I am saying. However, I do favor Tarbosaurus over E. sibiricum and Tyrannosaurus over E. caucasium

2.) Tarbosaurus beats T.rex? Just what, how, and/or why? Nevermind, look at the edit.

3.) Just so you know, the two tyrannosaurs were pitted against different Elasmotheirum species.

Edit: You claimed you voted Tarbosaurus over T.rex (which I believe implies was in T.rex vs. Tarbosaurus), yet your comment there suggests otherwise.

t-rex takes this by miles its like putting a sumatren tiger against a siberian tiger.


I'm confused, would you care to explain?

I think he meant to say that he voted tarbosaurus over elasmotherium on another fight, not t.rex.

Umm, ok. I got a bit confused. I still think T.rex wins to E. caucasium and Tarbosaurus wins to E. sibiricum.

Tyrannosaurus rex wins most of the time. The steppe rhinoceros certainly has a chance, but the t-rex has the edge.

I have to make a comment on the fanboyic assertion about T. rex' pedal unguals made two pages ago:

T. rex foot claws are not particularly large or sharp for a dinosaur. In fact, large theropod pedal unguals are used for creating friction while running, not as weapons. According to Holtz, tyrannosaurid foot claws are less pointed than those of carnosaurs.

Considering what I've readed untile now, seems that this forum have chosen to ignore completely the false and revisionistic claim about the T-Rex being a scavenger. I really appreciate this.
OT, I think the theropod would win more often than not, mostly becouse of his experience in facing big, quadrupedal and horned opponents.

@broly: I just wanted to clarify that was a madeup myth, not bash on dinosaur which would be useless anyway since that guy took insults as compliments...

Oh, alright (though I'm not broly). I forgot if you ever picked a winner in this matchup? Who do you think wins this?

Edit: Nevermind, looked back into the thread.

From the description above, the steppe rhinosaurus sounds less robust than modern rhinosauraus's. I might favour a scaled up version of a white rhinosaurus against a TRex, but my guess is (and I can only guess, given the lack of information) that the TRex would win this encounter.
