Hello Jem. It has been a while!
1. Pitbull vs Caracal: The American Pit Bull Terrier will weigh around 50% more than the caracal. American pit bull terriers, when game-bred, are extremely good combatants for their weight range. They have great durability, endurance, strength, and tenacity. A caracal is well-armed (bite & sharp claws), quick, agile, & athletic, and is accustomed to dealing with other predatory animals in its habitat. The APBT will rush in immediately and attempt to latch onto the caracal with its jaws (and begin shaking & pulling). The slashing claws of the caracal can rip into the APBT, but it's ability to use them effectively will be hindered once the dog seizes it. The caracal has more diverse weaponry (jaws and claws), but the APBT has a size advantage and a much bigger bite. A pet APBT might be repelled by a caracal, but a game-bred one won't be. Pitbull wins.
2. Caracal vs Gray Langur: These animals will weigh about the same. Caracals are lynx-like cats with large ears and a tawny hide. They are quick, agile, and athletic. Caracals usually prey upon smaller animals, but larger prey items can be taken. Their jaws and sharp claws make them solid fighters. Gray langurs are monkeys that feed upon fruit and vegetation. They aren't as formidable as, let's say, a baboon, and their teeth aren't nearly as imposing (canines are much shorter in comparison). A caracal is more equipped for battle than the langur, and will have the edge in any confrontation. Caracal wins.
3. Wolverine vs Chimpanzee: The chimpanzee will be 3 times heavier than the wolverine. The chimp will have the advantage of being able to grab and bite from many angles, but will probably not have the know-how to effectively finish the mustelid. The wolverine has strong claws, jaws that can crush bone, and tough skin, but it will find it difficult to overpower an ape of this size. In a realistic encounter the wolverine will easily drive the chimp away, but in a fight to the finish the chimp will figure out how to utilize its physical advantages and prevail most of the time. Chimpanzee wins.
4. Snow Leopard vs Chacma Baboon: A snow leopard can weigh about 75-80% more than a chacma baboon. Snow leopards usually reach 55kg, but can max out at 75kg on rare occasions. Chacma baboons usually reach 31kg, but can max out at 41kg. Snow leopards have the attributes shared by other big cats (agility, quickness, killing know-how), and have strong jaws & sharp claws (to hold/swipe with). They can overcome prey items 3 times their own weight. Chacma baboons have good mobility, grabbing hands, & sharp upper canines that can cause serious injuries to an adversary in a short amount of time. Baboons often deal with African leopards (and have injured them), but usually fall victim to predation by these cats. This is a dangerous fight for the snow leopard, but it should be able to use it forelimbs quickly enough to control the baboon's movement and finish with a throat bite. Snow leopard wins.
5. Olive baboon vs Kangal: The Kangal will weigh over 75% more than the olive baboon. Baboons have good lateral & vertical movement (can dodge & leap well), have hands to grab with, and long, sharp upper canines that can cause grievous injuries to an adversary. Kangal dogs are powerful & stocky, and have been used to defend flocks from predators. The Kangal will try to subdue the baboon with its large bite (and has a strong bite force), and has the endurance to sustain an attack for a long time. The baboon will try to counter by moving quickly to avoid the jaws and counter-attacking with its own set of teeth. This fight certainly has the potential for 2 different outcomes, but the body of the baboon won't be able to withstand an assault by the large bite of this dog for long. Some well-placed bites from the baboon's "fangs" (2" upper canines) can turn the tide quickly, but most of the time the larger canid will induce enough damage with its large jaws to overcome the smaller animal (assuming the dog is trained). Dangerous fight for the dog, but Kangal wins.
6. Rottweiler vs Dogo Argentino: This will be a decent contest, but only because the Rottweiler will have about a 30% size advantage. Dogos are great fighters, and are used to track wild boar and aid in its capture. Dogo Argentinos are powerful dogs adept at grabbing and holding with their jaws. Rottweilers are aggressive and have a strong bite, but they are a cut below Dogos when it comes to fighting. Slight edge to the smaller Dogo Argentino.
7. Dunkleosteus vs Liopleurodon: See the main event!
8. Tiger Shark vs Walrus: The walrus will weigh almost 3 times as much as the tiger shark. The walrus has very tough hide and is armed with long tusks (3') that can injure or kill adversaries with a well-placed stab. The tiger shark has jaws armed with razor-sharp teeth that are capable of penetrating the hide of the walrus. The walrus has better overall mobility in the water than the shark does, but can't duplicate the shark's bursts of speed. This battle will depend on whether or not the tiger shark can inflict enough serious wounds to the walrus before it gets impaled by the pinniped's tusks. Sharks are ambush predators, and aren't especially good as face-to-face combatants. Edge to the walrus.
9. Clouded Leopard vs Gray Wolf: The grey wolf will weigh over 2 1/2 times more than the clouded leopard. Clouded leopards are quick, athletic, & very agile, and have upper canines as long as matchsticks. Grey wolves have strong bites & great endurance. The clouded leopard has the ability to injure the wolf with its long teeth & sharp claws, but it won't have a way to effectively repel the big bite of the much larger animal on most occasions. Gray wolf wins.
10. Great White shark vs Southern Elephant seal: The elephant seal can weigh almost twice as much as a great white shark. The elephant seal will have greater mobility overall, but it's bite will have minimal effect on the shark without accumulation. The shark's bite can easily breach the hide of the seal, and at that point the mammal will be in trouble (from blood loss). The elephant seal won't have a way to dispatch the shark before taking bites itself, and that will bring its doom. The seal might be able to bully the shark into a retreat on some occasions (sharks aren't great face-to-face fighters; they prefer ambush), but will need to avoid one that isn't scared off. Overall edge to great white shark.
11. Hippopotamus vs Kodiak Brown Bear: The hippo can weigh over 3 times as much as the bear. Kodiak bears are powerful fighters, but don't have the size to take on a hippopotamus. Hippos have jaws that can open almost 4ft wide, and are armed with sharp lower canines that can cause massive damage to a bear. The Kodiak bear can injure the hippo with paw swipes, but it will take a lot of them to have great effect (the hippo has very thick skin). The bear doesn't have the lateral quickness to avoid getting bit by the hippo's jaws (which would be key), and doesn't have the leaping ability (like a big cat) to jump on top of the hippo. Brown bears can usually handle most animals close to their weight range, but the much larger hippo will be too formidable for it. Hippopotamus wins.
12. Dinohyus vs Amphicyon ingens: Dinohyus (also known as Daeodon) weighed almost 70% more than Amphicyon ingens. Dinohyus was the largest of the "terminator pigs", and somewhat resembled a bison-sized warthog. It had a large head (about 1 meter long), a bone-crushing bite, and could deliver slashes with its tusks. The powerful neck muscles of Dinohyus suggested a strong bite force, and although its incisors were blunt, its canines served as dangerous weapons. Gashes in the skulls of Dinohyus indicated these beasts likely fought among themselves. Amphicyon ingens (also known as a "bear dog") had a bear-like body and a dog-like head. Its limbs were strong, as well as its bite. A face-to-face battle will likely favor the larger Dinohyus, as the Amphicyon's attack will bring it within close quarters and in range of the pig's bite/tusks. Although I consider Dinohyus to be more formidable in a one-on-one encounter with the Amphicyon ingens, the species of Amphicyon as a whole was likely strong enough in its overall effect (maybe an advantage in numbers as Dinohyus wasn't plentiful, better ability to hunt, competition for the same food/habitat, better adaptability perhaps?) to negatively impact the species of Dinohyus. In the same way the grey wolf might outcompete the puma in a given area (even though a puma will best a grey wolf one-on-one), the same may have been true here. Not sure, but in a one-on-one rumble, Dinohyus has the edge.
13. Amphicyon ingens vs Polar Bear: Amphicyon ingens weighed about 85% of a polar bear's weight. Some Amphicyons were as large as a big dog, while others (like Amphicyon ingens) could weigh close to 590kg. Polar bears are extremely strong from nose-to-tail, and demonstrate this strength in everyday life (tacklng walruses, pulling large seals out of water, busting holes through thick ice). Bears also have great durability and endurance, and the polar bear has 4" of blubber beneath its fur. In this battle the polar bear will have the advantage of better paw usage (to grab, hold, swipe, and control movement), but the Amphicyon will have a bigger bite and slightly better mobility (which won't be a great advantage at close quarters). Both can win, but slight edge to polar bear.
14. Dinohyus vs Walrus: A bull walrus can weigh about 90% more than Dinohyus (Daeodon). Dinohyus was the largest of the "terminator pigs", and somewhat resembled a bison-sized warthog. It had a large head, a bone-crushing bite, and could deliver slashes with its tusks. Walruses have extremely tough hides (which often hold up quite well to polar bear attacks), and meter-long tusks that serve as dangerous weapons when defending themselves. In this battle, Dinohyus will have much greater lateral mobility, but will find it challenging to penetrate the walrus' tough hide while the pinniped is actively resisting (using its body weight and tusks to fend the pig off). The walrus won't be quick enough to stab Dinohyus if the pig is simply looking to stay out of range, but any close-quarters attack by Dinohyus may leave it vulnerable to a counterattack. Neither animal will be able to make much headway without a lot of time passing by, and a stalemate may result. Slight edge to Dinohyus on land (only because it can avoid the walrus' offense better than the other way around); any reasonably measurable water depth will swing things into the walrus' favor.
15. Hippopotamus vs Walrus: Hippos are usually heavier than walruses (around 50% more). Hippopotamuses have jaws that can open almost 4ft wide, and they have large teeth that can bite & slash opponents. Walruses have thick, tough hide that gives them great protection from many attacks and long tusks (around 3ft long) that can be used to stab. If a hippo battled a walrus on land, the hippo would be able to move around much easier than the walrus could. It could bite the walrus and probably avoid getting stabbed with its tusks most of the time. The hippo's bite wouldn't be able to get through the hide of the walrus easily, but it could do it using the sharp-edged lower canines in its jaws. The walrus could injury the hippo with its tusks if the hippo got into range, but the walrus would have a hard time hitting its mark without being able to move around well. In shallow water, the walrus could move around a little better, but it wouldn't be enough to give it a good chance against the larger hippo. In water deep enough for the walrus to swim around freely, it would gain the upper hand against the hippo. It would be able to swim around easily and stab the hippo with its tusks. Hippos can't really swim, but they walk along the bottom of the river and push off on the ground to bounce up and down when they move about. Hippo wins on land or in shallow water; walrus wins in water over 5 or 6 ft deep.
16. Walrus vs Southern Elephant seal: A Southern elephant seal can weigh over twice as much as a walrus. Even though the walrus is smaller, it is better equipped for this battle (presence of 1m tusks and extremely tough hide). The elephant seal's bite will cause minimal damage to the walrus without great accumulation, but the tusks of the walrus can seriously injure the elephant seal if they impale its body. The walrus will have a maneuverability advantage in the water as well. A walrus will likely give way to the larger animal in a realistic encounter (especially on land), but in a serious battle the tusked pinniped will have the advantage due primarily to tusk usage. Slight edge to walrus.
17. Dunkleosteus vs Livyatan: Livyatan melvillei will weigh at least 7 1/2 times as much as Dunkleosteus; perhaps a lot more. Dunkleosteus (giant armored fish) was covered anteriorly by armored plating, and had an extremely strong bite force that enabled it to bite through almost anything with ease. It was capable of moving swiftly at times to pursue prey, but it wasn't a very agile creature. Livyatan melvillei was almost a sperm whale's length (20m), but probably weighed half as much (but max sizes made its weight closer to the sperm whale's weight than half). However, it had large teeth on its upper & lower jaws. Although Dunkleosteus will be able to bite easily into the body of the Livyatan, it will need several of them to overcome the much larger animal. Livyatan's huge bite will probably dispatch the Dunkleosteus with one chomp if the posterior half is targeted, and that gives it the advantage. Livyatan wins.
18. Liopleurodon vs Livyatan: These 2 were likely similar in weight, but there are lots of varying estimates for the size of Liopleurodon. One of the more commonly used weigh ranges for Liopleurodon assign its weigh between 5-15 tons, others between 20-25 tons, while still others have its weight rivaling some of today's whales. Liopleurodon had a torpedo-shaped body with four large flippers that enabled it to achieve great agility & acceleration through the water. Its jaws were huge (1/5 of its body length), lined with sharp teeth designed to grab and crush. Livyatan was about the same length as a sperm whale, but probably only half its weight. It had large teeth on the upper and lower jaws. Liopleurodon will have the advantage in maneuverability in this battle, and that will be paramount. It will be able to deliver bites more readily, and will have the advantage if weighs are similar. A Liopleurodon in the 5-15 ton weight range will be too small to tackle a 30+ ton Livyatan melvillei, but a 20-25 ton version of this pliosaur will prevail more times than not. As long as the Liopleurodon is at least 2/3 of the Livyatan's weight, I will favor it.
19. Main event: Liopleurodon vs Dunkleosteus: Even the smallest estimates for Liopleurodon place it as weighing 25% more than the Dunkleosteus (giant armored fish). Liopleurodon had a torpedo-shaped body with four large flippers that enabled it to achieve great agility and acceleration through the water. Its jaws were huge (1/5 of its body length), lined with sharp teeth designed to grab and crush. Dunkleosteus was covered anteriorly by armored plating, and had an extremely strong bite force that enabled it to bite through almost anything with ease. It was capable of moving swiftly at times to pursue prey, but it wasn't a very agile creature due in part to its armor plating. In this battle, the Liopleurodon will have a significant mobility advantage, but the Dunkleosteus will be better-protected from injury. The pliosaur will be able to land bites with greater ease, and will overcome the Dunkleosteus if it targets the unprotected areas on the fish. Regardless of size used for the Liopleurodon (5-25+ tons), it will win more times than not. Liopleurodon wins.
