Arctodus simus Arctodus (Greek, "bear tooth") — known as the short-faced bear or bulldog bear — is an extinct genus of bear endemic to North America during the Pleistocene ~3.0 Ma.—11,000 years ago, existing for approximately three million years. Arctodus simus may have once been Earth's largest mammalian, terrestrial carnivore. It was the most common of early North American bears, being most abundant in California. It was native to prehistoric North America from about 800,000 years ago, and became extinct about 12,500 years ago. It has been found from as far north as Ikpikpuk River, Alaska to Lowndes County, Mississippi. It is one of the largest bears in the fossil record and was among the largest mammalian land predators of all time. The type specimen came from Potter Creek Cave in Shasta County, California. It would have weighed up to 700-800 kg. -738x591.jpg) Megalosaurus bucklandii Megalosaurus (meaning "Great Lizard", from Greek, μεγαλο-/megalo- meaning 'big', 'tall' or 'great' and σαυρος/sauros meaning 'lizard') is a genus of large meat-eating theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Europe (Southern England, France, Portugal). It is significant as the first genus of dinosaur (outside of birds) to be described and named. n many ways, Megalosaurus was your garden-variety theropod dinosaur, indistinguishable from a host of other big-headed, large-toothed carnivores of the late Jurassic period. What really sets this predator apart is the fact that it was the first dinosaur ever to be discovered and named: a fossilized femur of Megalosaurus was dug up in England in 1676, but it wasn't until 150 years later--after further discoveries--that it was given its name, Greek for "great lizard," by the early paleontologist William Buckland. Size about 30 feet long with weight estimates varying from 700 kg (1,500 lbs) to 1,100 kg (2,400 lbs).  Credit to Wikipedia |

Weights are actually surprisingly close! (Honestly, I thought Megalosaurus would've been MUCH bigger). Eitherway, the theropod should win this via overpowering the bear. At parity, it could go eitherway but I'll lean towards Megalosaurus once again.

Well, as we discussed earlier, it may have been bigger. But weight estimates do range a lot.
I will make a size chart for this soon. Stay tuned!
(I'd favor the dinosaur at average and parity as well btw. One bite on an arm, no more grappling)

Honestly, a parity discussion is probably necessary for the bear to have a chance. Grappling is its best option here and it'll need a lighter Megalosaurus for that. But like you said though, one bite to an arm, and no more grappling.

Well yeah, you have a point.
Not in the same league as Agriotherium vs Bistahieversor/Sauroniops, but Megalo wins solidly

Megalosaurus takes this fight. Its head is larger, more robust, and has a wider jaw gape with teeth designed for tearing flesh. Looking at the size comparison, it would seem that Megalosaurus could fit A. Simus' head in its mouth, which speaks for itself. I would also wager Megalosaurus having a more powerful bite force than A. Simus.

Out of the vast majority of bears, Arctodus Simus is argued to have one of the more powerful bites. I cannot provide a source, but I do remember reading an article that claimed A. Simus could exert roughly 9,000 newtons of force, which translates to around 2,000 lbs. An impressive bite, but it seems to be proportional to its mass, which is unsurprising. Megalosaurus however, likely had an "overpowered" bite force due to its high mechanical efficiency of the skull, which is common for members belonging to Megalosauridae. |

Some, such as Torvosaurus, are so mechanically efficient they take on a tyrannosaurid-like appearance and structure  Now we don't have any good skull material from Megalosaurus, just fragments, but going by Hartman's skeletal and its relatives, that is NOT something you want to grapple with |

With jaws equipped with teeth such as that, you would not want to anywhere near them! Torvosaurus is a complete monster. I have heard claims that T. Tanneri could exert 36,000 newtons, which equates to roughly 8,000 pounds! |

Megalosaurus is approximately the same size as Torvosaurus tanneri, so we could expect a similar bite force. As I said earlier, a bite to an arm is the end of the grappling |

I REALLY wanna root for the bear but... Look on the bright side. At least this isn't short faced bear vs Sauroniops! (well, not anymore at least) On a more serious note, any biases or preferences aside, who do you think should win this at parity? |

I mean, it's like a discount Torvosaurus but the big reptile still has deadly jaws that would instantly end the fight. |
