Err, not quite. Utahraptor is kind of overkill for a grizzly; over twice the weight and significantly more dangerous weapons. I think a good matchup is either 3-4 Deinonychus (111 kg each) or one-on-one Dilophosaurus Utahraptor's claim to fame is that it was by far the biggest raptor ever to walk the earth; adults measured about 25 feet from head to tail and weighed in the neighborhood of 1,000 to 2,000 pounds, compared to 200 pounds for a more typical raptor, the much later Deinonychus, not to mention the 25- or 30-pound Velociraptor. In case you were wondering, the two-ton Gigantoraptor from central Asia technically wasn't a raptor, but a large, and confusingly named​ theropod dinosaur. 1400 pound raptor vs 1400 pound Kodiak bear. Yes, Gigantoraptor was an oviraptorosaur. I agree very large bears make for a more fair fight, but AVERAGE sizes Utah is too large

Of course; you are correct. Great thing about grizzlies ( Ursus arctos ) is, so many size variations. In reality, there is no such animal as "the average grizzly." Each population of brown bear has its own average size, color, diet, etc. The is a huge difference between the average Kodiak bear and the average barren ground grizzly or the average Himalayan red bear ( for examples ). But in such a face-off, I would not consider averages but rather ( in this case ) weight parity. In this particular face-off, I would not wager. I cannot see myself betting against the bear, but would have little confidence in the outcome.

Bears fighting dinosaurs is syfy fantasy. Even Arctotherium angustidens would live like a jackal during the Mesozoic. Here is a picture of Indarctos battling Allosaurus. This bear was actually the size of a grizzly.

Tbh Indarctos is going to get absolutely annihilated by Allosaurus fragilis. It's way too small, like you said it's grizzly sized. A. fragilis is rhino-sized on the other hand.
Still, fantasy palaeoart is always fascinating. Nice artwork brobear!

Still, fantasy palaeoart is always fascinating. Nice artwork brobear! Thanks; but I'm not the artist You are right. Allosaurus would make a quick meal of any grizzly-sized bear. This artwork was done when it was widely believed that Indarctos was a giant bear; bigger than any short-faced bear. Why? From the topic: "Indarctos"...( quote ): Its bacula was, on average, 9.1 inches (23.3 centimeters) long — significantly larger than the penis bones of much bigger bears. Male polar bears, the biggest bears on Earth today, typically weigh 1,100 lbs. (500 kg), but their penis bone averages about 7.3 inches (18.6 cm) long, the researchers say. ( IMO ) if even Arctotherium angustidens were suddenly swept into the Mesozoic era, he would quickly become an insignificant scavenger living like a jackal. Dinosaurs are awesome.

How would the Jurassic Park size Raptor fair against a 1400 lb. Brown Bear?

A grizzly is a loner. He would have his paws full with just one large dromaeosaur.

The grizzly ( brown bear ) along with his first cousin the polar bear are the top-ranking predators of modern earth. One-on-one, no living land-based predator can defeat one of these bears in a face-off. This is not opinion; this is fact. But among the flesh-eating dinosaurs, we must look at some of their less-impressive members to choose a dino for a face-off against a grizzly. Long after the extinction of the dinosaurs, there have been some mammalian monsters also that might make a quick meal of a grizzly. The grizzly, along with the polar bear, cave bear and short-faced bears, have ruled since the late Pleistocene.

Short faced bear vs Kelmayisaurus is good - they both weigh around the same

I will be waiting. I believe grizzlyfan245 is very tech savvy (good in computer graphic skills).

Alright, Brobar and LarsMaritimus, here it is. Short faced bear is scaled to ~165 cm SH based on the very biggest specimen while Kelmayisaurus is ~9 meters total length/ Credit to blaze and Teratophoneus, respectively. Having said all that, I'm having a very hard time believing they weigh the same. Scaling down from relatives would get ~3 tonnes for Kelmayisaurus, and although it appears a bit more gracile than relatives it's not by much. The bear's ~800-900 kg, while the dinosaur is probably around 2.5 tonnes

No, the biggest bear ever might have reached as much as 3,000 pounds or even 3,500 pounds.... 1 3/4 tons. This would make the dinosaur roughly 1,000 pounds heavier. ( IMO ).
