We’re going to gather and present the pertinent data to show you what would happen in this battle of a titan vs. some of the toughest predators that are known to the world today.

Comparing a T-rex with a Lion, Grizzly Bear, and Saltwater Crocodile

 

What Are 2 Key Differences Between a T-rex and a Lion, Grizzly Bear, and Saltwater Crocodile?

The most significant differences between a T-rex, lion, grizzly bear, and saltwater crocodile are their morphologies and sizes. The T-rex is much larger than all the other animals put together, standing up to 20 feet tall and weighing 15,000 pounds at its utmost. Meanwhile, the other animals combine for less than one-fifth of that measure. Moreover, the T-rex is a medium-sized dinosaur while the grizzly bear and lion are quadrupedal mammals and the saltwater crocodile is a long, reptile with scutes and scales covering its body. These animals are all very different, and those differences will play a big role in this fight. After all, the unique creatures in this fight have different methods of attack, various ways to defend, and come from mixed environments that could help them thrive in this battle.

What Are the Key Factors in a Fight Between a T-rex, Lion, Grizzly Bear, and Saltwater Crocodile?

The biggest factors in this fight are going to be the size and offensive capabilities of the animals. For the grizzly bear, saltwater crocodile, and lion, the ability to deal damage to the larger creature is going to be very important to overcoming the T-rex. Moreover, their combined ability to take damage and survive in this fight is also important, and that is where their size comes into play. However, these are not the only elements that matter in this fight. We have five dimensions to explore. So, we’re going to assign one team or the other a cumulative advantage based on the information that we establish about them.

T-rex vs. Lion, Grizzly Bear, and Saltwater Crocodile Size

The T-rex has a massive size advantage in this battle. The average T-rex weighed between 11,000 and 15,000 pounds, stood up to 20 feet tall, and grew about 40 feet in total length. The other animals combined can’t make up these measures. Lions only weigh about 550 pounds, grizzlies can weigh over 1,000 pounds, and saltwater crocodiles can weigh well over 1,100 pounds in some cases. Nevertheless, they are facing an absolute monster that is many times their collective size. The T-rex has a size advantage in this fight.

T-rex vs. Lion, Grizzly Bear, and Saltwater Crocodile: Speed

The T-rex was not necessarily a slow animal, but its speed is low compared to the lion and the grizzly bear. T-rex could move at about 17 mph, but the grizzly and lion can move at 35 mph or higher. The saltwater crocodile is fast in the water, averaging about 15 to 18 mph while swimming. The lion, grizzly bear, and saltwater crocodile have a speed advantage. The T-rex won’t be able to get away.

T-rex vs. Lion, Grizzly Bear, and Saltwater Crocodile: Defenses

The T-rex has some helpful defenses that give it an advantage. For one thing, it’s so tall that the lion and crocodile may only attack its legs and possibly its underside if it’s a small one. Its thick body can take a lot of damage before keeling over, and its head and neck, the vulnerable areas that most predators go for, are too thick for a bear, lion, and saltwater croc to get through. Meanwhile, the lion’s speed would be its best defensive trait in this fight. The same goes for the bear, but its general thickness and size also help. Meanwhile, the saltwater crocodile can always hide in water and make it hard to attack. Still, in a direct conflict, none of this matches up against a T-rex’s power. The T-rex has a defensive advantage in this fight.

T-rex vs. Lion, Grizzly Bear, and Saltwater Crocodile: Offensive Capabilities

Grizzly bears are effective killers because they use their body weight, claws, paws, and bite to kill their foes. They can deliver vicious bites that puncture several inches deep into their prey. Like grizzly bears, lions use their fangs to bite into the skull and backs of their foes. Meanwhile, the saltwater crocodile has a deadly bite. They latch onto their prey, drag them into the water, and then tear them apart. None of that is as powerful as a T-rex’s bite. A T-rex’s bite power could be as high as 12,800 psi. If it gets a hold of any of its opponents, they’re going to die. The 12-inch teeth of T-rex would shred their flesh, break their bones, and puncture every vital area. T-rex has a substantial offensive advantage in this battle.

T-rex vs. Lion, Grizzly Bear, and Saltwater Crocodile: Predatory Behavior

Lions are ambush predators in some cases, and they’re cursorial predators in others. That means they can surprise foes or chase them down and wear them out. Meanwhile, grizzly bears are more likely to scavenge meals and attack prey that they happen to find as opportunists. Saltwater crocodiles attack from the water, using ambush tactics to assault their prey. T-rex is similar to the grizzly in that it was an opportunist as well as a scavenger. Based on these elements alone, the only creature with a distinct predatory advantage are lions, animals that can end a fight in a moment or continue the battle if that fails. The lion, grizzly bear, and saltwater crocodile has an advantage in predatory behavior, but not predatory prowess.

Who Would Win in a Fight Between a T-rex against a Saltwater Crocodile, Grizzly Bear, and a Lion?

A T-rex would win a fight against a lion, grizzly bear, and saltwater crocodile. The T-rex could eat them and still be hungry later on in the same day. Let’s explore the battle anyways. We’re assuming this fight happens near a body of water with ample hiding spots for the lion and grizzly bear to come storming out. The crocodile could burst out of the water, raring to go. Its first attack would see it biting the T-rex on the foot. The T-rex responds by biting the crocodile, instantly killing. What it doesn’t know is that the saltwater crocodile’s sacrifice was a ruse, allowing the lion and bear to attack. The lion jumps on the T-rex’s side, scratching and clawing its way up the flank. Meanwhile, the grizzly bear stands on two feet and attacks the T-rex’s underside. The T-rex, obviously bothered by something attacking its underside, turns around suddenly and knocks the bear over before pinning it to the ground. The T-rex can’t reach the lion that has now climbed on its back though. The dinosaur stomps over to a nearby tree, and the lion is forced to abandon its attack before it’s crushed against the vegetation. The lion, seeing that the tide has turned in the battle, decides to call it a day and runs off. The T-rex may have had trouble catching this animal in the fight, but the lion would never have enough power to do serious damage to a T-rex. Meanwhile, the dinosaur goes back to finish eating the grizzly bear.
