Comparing a Stegosaurus and a T-Rex
What Are Key Differences Between a Stegosaurus and a T-Rex?
The most notable differences between a Stegosaurus and a T-Rex include their morphology and predatory behaviors. Stegosaurus was a quadrupedal herbivore with an unusually small head and brain, a row of bony plates standing on its back, and a long tail with spikes on its end. T-Rex was a bipedal carnivore with large, muscular legs and a massive head featuring 50 teeth measuring 12 inches each. These defining characteristics of the two dinosaurs will help us understand the power that each animal brings to the fight. However, we need other pieces of this puzzle to help determine which dinosaur had the best chance of dominating the other one.
What Are the Key Factors in a Fight Between a Stegosaurus and a T-Rex?
Aside from their unique bodies, we need to look at typical elements that help one animal win fights against the other. That’s why we’re going to examine traits like speed, movement, defenses, and more, see which of these reptiles has the advantage in each case, and then review all the data to determine a winner!
Stegosaurus vs T-Rex: Size
T-Rex was larger than the Stegosaurus in two out of three measures. The average T-Rex could weigh up to 15,000lbs, stand 20ft tall, and measure up to 40ft long. The Stegosaurus could weigh up to 15,400lbs as a short, thick dinosaur. It would often stand about 7ft-9ft at the hip and 14ft overall and could measure 20ft-30ft long! T-Rex has the size advantage for this fight!
Stegosaurus vs T-Rex: Speed and Movement
T-Rex was faster than Stegosaurus. This bipedal hunter could walk at 17 mph with its long strides, and some scientists believe that it could have moved even faster. However, we know that the Stegosaurus was much slower, perhaps reaching 4.3 mph as a large, slow quadruped. The T-Rex has a speed advantage over the Stegosaurus.
Stegosaurus vs T-Rex: Defenses
The Stegosaurus had great defenses stemming from its large body, strong bones, and dermal plates. These bony vertical plates were probably used for defense against predators, but their use is not fully understood. We don’t know if the Stegosaurus could move or align them by flexing the muscles below. The T-Rex had its size, speed, and hunting senses to keep it safe. That was probably enough to fend off any potential attacks by all but the biggest enemies. The Stegosaurus has the defensive advantage.
Stegosaurus vs T-Rex: Offensive Capabilities
The Stegosaurus was far from an offensive powerhouse, but it could defend itself. This large herbivore could swing its tail at predators, smashing 4 spikes measuring between 2 and 3ft into its enemies. The only downside was that this tail was situated relatively close to the ground rather than held aloft, so it may not have been able to take down large predators. Still, a 3ft spike penetrating the body cavity of a dinosaur would prove more than uncomfortable if it wasn’t immediately fatal. T-Rex had a simple approach to offense: bite things. The T-Rex had a massive head with immensely powerful jaws that could help them exert between 8,000 and 12,800 PSI on their prey, one of the strongest bite forces of any terrestrial animal. Each bite would drive 12-inch serrated teeth into its prey, instantly killing or shearing massive amounts of flesh from its prey. Moreover, T-Rex had the speed needed to catch a lot of its prey. T-Rex has the offensive advantage.
Stegosaurus vs T-Rex: Predatory Behavior
T-Rex was most likely an apex predator, but some scientists also think that it was a scavenger. Either way, this creature could find large quantities of food and secure it by stealing kills or killing outright. Stegosaurus was an herbivore that ate significant amounts of vegetation to maintain energy stores and support its large body. T-Rex has the advantage in predatory behaviors.
Who Would Win in a Fight Between a Stegosaurus and a T-Rex?
T-Rex would win a fight against a Stegosaurus. Although Stegosaurus possessed a powerful method of attack that could have severely harmed the T-Rex’s legs, a few problems exist with the herbivore fighting off the carnivore. For one thing, Stegosaurus was not an intelligent dinosaur. It had an incredibly small brain, even for one of these creatures. It was probably not going to time a perfect hit against the rapidly encroaching T-Rex. Also, if Stegosaurus was going to land an attack, it would probably land on the lower portion of the tall T-Rex, meaning the T-Rex was going to be nearly on top of the Stegosaurus before the tail swing happened. In that case, the T-Rex would be in a position to launch a far more devastating attack. Even if the Stegosaurus hit the T-Rex, it would still be too close to escape the hungry predator. T-Rex would probably bite the animal’s head or neck or attempt to knock the dinosaur over entirely to avoid the dermal plates on its back. No matter how we look at this situation, things don’t look good for the Stegosaurus. Interestingly, the T-Rex and the Stegosaurus never walked the Earth at the same time as one another. They were separated by almost 50 million years in time, almost the same amount of time between the T-Rex and modern human beings.
