10 : The Concavenator, the Cretaceous camel
Scientists found that dinosaurs with longer legs could run faster, according to a study published in Scientific Reports. This pattern certainly fits the Concavenator, which ranks 10th in dinosaur speed.
The Cretaceous Camel, also known as the humpback dinosaur, has no shortage of odd anatomy, including its legs.
Persons, a paleontologist at the University of Alberta, adds that Concavenator had long legs and small feet, suggesting it hunted only on firm, dry terrain. If the Concavenator tried to run on soft swamp ground, its weight and small toes could have slowed it down.”

Over 50 different predatory dinosaur species from museum collections around the world were measured for this study. In terms of size, dinosaurs were smaller than chickens and longer than buses.
Researchers developed an equation to determine a dinosaur’s “superficial limb proportion score” a measure of the species’ speed adaptation. A consideration was also made for the weight support requirements of each dinosaur.
9 : The Carnotosaurus, the South American demon
Persons explains that you cannot compare small dinosaurs to large dinosaurs without taking their body mass into account.
Among the fastest dinosaurs, Carnotaurus came in ninth. With two devilish horns, it looked like a true demon.
In Carnotaurus, the dimensions of this muscle were excessive, explaining the animal’s great speed.
8 : The Deltadromeus, the definition of speed in a small body
The relationship between speed and leg length is generally observed in living beings with motor abilities. In terms of speed and legs, cheetahs are the fastest and have longer legs than lions, which are faster than hyenas and have relatively longer legs.
There is no doubt that the Delta runner would be the fastest species of all if it were a real species. Furthermore, the Deltadromeus thrived in prehistoric Egypt because it was the fastest in its ecosystem. Prey for this dinosaur was the same as for dinosaurs that had greater muscle mass, but were slower. Carcharodontosaurus and Spinosaurus are examples.
7 : The Troodon, the sprinter
A dinosaur with a formidable velocity has been discovered by scientists to be the Troodon. In comparison, a velociraptor is similar to a turtle. In addition, the velociraptor does not rank highly in terms of speed, due to its anatomy. Even though the Troodon is the same size as the Velociraptor, it has a much greater physical strength.
6 : The guanlong
Guanlong was a tyrannosaurid that was the size of a wolf. It was both a hunter and a prey, unlike its descendant, the tyrannosaurus, which ruled over its fellow dinos as king. This dinosaur needed to run fast. Due to its speed, it had to catch prey that others could not reach. Eventually escaping its predator’s stalking.
5 : The Tyrannosaurus Rex, the great dinosaur
In addition to being big and fast, the tyrannosaurus rex was also very powerful. In comparison to its predatory congeners, this specimen had longer legs. Compared to Allosaurus and Gigosaurus, it performed better. A high-speed racer’s ankle and foot are also equipped with shock-absorbing components for easy rebound on the ground.
4 : The Gorgosaurus, the dinosaur with the remarkable throat
Gorgosaurus has the longest legs of all tyrannosauridae, making it faster than Tyrannosaurus rex. The Gorgosaurus, like all the dinosaurs in this ranking, was believed to be incapable of maintaining its speed for long periods of time. There was a time limit to these bursts of speed.
It appears that a dinosaur four feet long fed on newborns and raptors, according to fossils found in its stomach.
3 : The Sinocalliopteryx, a hunter on the lookout
Sinocalliopteryx, ranked third in this ranking, was undoubtedly one of the fastest dinosaurs of its era. The fossil is believed to have originated in China during the Lower Cretaceous period. The animal had to wait for its prey until it was able to catch it. For Sinocalliopteryx to reach its prey so quickly, it must have had a good vertical elasticity.
2: The Saurornithoides, the number one bird
Compared to its congeners, the Saurornithoides was the fastest. The anatomy of this bird was very similar to that of modern birds. It is a member of the family Troodontidae. The Saurornithoides uses its center of gravity and the very adapted mechanics of its limbs to overcome its lack of muscular power in its tail.
In the Cretaceous period, Saurornithoides migrated from China to Mongolia. Mammals, insects, and small lizards were part of its diet.
1 : The Nanotyrannus the fastest dinosaur of all time
Nanotyrannus was determined to be the fastest dinosaur by the researchers based on their study. Nanotyrannus was the fastest sprinter of his time, reaching 50 miles/h. Having lived during the same time period as T.rex, it probably specialized in hunting smaller and faster prey that T.rex couldn’t catch. In order to reach such a speed, Nanotyrannus had to push the long legs of tyrannosaurs to the extreme.
Why were bipedal dinosaurs the fastest?
There’s a good reason why all dinosaurs in this ranking were bipedal. The majority of quadrupeds in prehistoric times were cold-blooded herbivores. Species velocity is determined by anatomy and blood flow mechanisms, according to a popular theory.
Due to their low metabolic energy, cold-blooded creatures moved slowly. A theropod (a two-legged meat-eating dinosaur) is warm-blooded and therefore has a metabolism that can sustain a high running speed.
Why is the velocity of the T-Rex often disputed?
There is a scene in Jurassic Park in which a T-rex races a jeep. As a result of this scene, the T-rex must have had
great speed. It is the king of lizards, after all. It is often very popular with children because it is the most famous dinosaur of the Mesozoic. If your child likes big predator discover how to teach him to
draw a dinosaur.
That’s not true! A recent study has demonstrated that the T-rex ruled the fast walking world. A study conducted by William Sheller and his colleagues from the University of Manchester concluded that the Tyrannosaurus could not exceed 12 miles/h without breaking its bones.
A cursory comparison of a T-rex’s limbs with those of a biped of our time used to estimate a dinosaur’s running speed decades ago. The possibility of a 39-feet-long dinosaur being fast was then conceivable.
Researchers were able to obtain more accurate data by using biomechanics. The analysis of different species was no longer limited to their morphology.
The speed of dinosaur movement was influenced by bone stress in William’s and his colleagues’ study. A bone can only withstand a certain amount of pressure during a run before breaking. It was necessary to consider the weight of the T-rex (about 7 tons) as well as the mechanical properties of the bones when performing this study.
Research conducted without accounting for muscle fatigue estimates the Tyrannosaurus’ top speed at 33 miles/h in previous studies. A hypothetical sprint race between Usain Bolt and the T.rex would have resulted in the T.rex’s victory. Based on the new data, the T.rex would have broken the bones of its foot while running at such a speed. During the Cretaceous period, the T.rex probably wasn’t the most athletic animal.
The general public, however, believes that a T. rex that does not run fast is not cool. Moviegoers are willing to suspend their disbelief, even though the cinematic representation of this big lizard is not accurate.
What about the speed of the Compsognathus?
According to older research, Compsognathus was the fastest dinosaur, reaching speeds of 39 miles/h. Even though this is faster than Velociraptor’s estimated speed, it can’t compete with the king of this ranking.
Its name means “elegant jaw” and describes a pudgy dinosaur. It weighed about 8 pounds and measured about 5 feet.
How do we know the speed of a dinosaur?
Dinosaurs have also been studied by David Evans and his team at the Royal Ontario Museum. Their studies suggest that fused bones in a dinosaur’s lower leg could have improved its agility and speed.
There are four main things we know about dinosaur speed today, even if it is not a perfect science:
- Fossilized footprints;
- Their own anatomy (morphology);
- Comparison with modern animals;
- Laws of physics (biomechanics).
Fossilized Footprints
Paleontologists can determine some key facts about dinosaurs by studying fossil footprints. Footprints and the analysis of their spacing are the most effective methods for understanding dinosaur movements from fossils.
A dinosaur’s footprints are essentially fossilized steps of movement. Our estimates of their speed and movements are more accurate the better and better preserved the footprint is.
The morphology of dinosaurs
Dinosaurs’ exact speed cannot be determined from footprints, which are too limited. It’s hard to find enough of them!
The morphology of a specimen (basically the anatomy) is also a good method of learning how dinosaurs moved. Paleontologists can learn a lot about dinosaurs by examining their skeletal structure and deducing their anatomy. As a result, they knew dinosaurs stood on their sides (just like modern reptiles) rather than with their legs under their bodies.
Comparison with modern animals
To estimate how dinosaur sizes might have moved, this metric uses observations of current animals. Due to the similar size of Triceratops and elephants in our era, scientists can draw comparisons between the movements of elephants and Triceratops. Dinosaurs of all types are studied using this method.
The biomechanics
In addition to using physics to determine dinosaur movements, paleontologists also use biomechanics. Muscle patterns and gravity, along with other factors, are taken into account when evaluating the influence of the laws of physics on prehistoric animals. Through the combination of these elements, the scientist was able to visualize the dinosaur’s movements and its speed in the best possible way.
The influence of metabolism on the speed of dinosaurs
A dinosaur’s speed could differ depending on whether it was warm-blooded or cold-blooded. The warm-blooded dinosaurs were mostly hunters and had a fast metabolism. Herbivores, on the other hand, tended to be larger and had a slower metabolism, so they weren’t adapted to a speed race.
The speed score of Tyrannosaurus tends to support this hypothesis. T-rex is slower than one would expect for a carnivore. Its body mass prevents Tyrannosaurus from going faster than 19 km/h.
Despite the fact that dinosaurs are reptiles, they should all be cold-blooded. A controversy has long existed here that paleontologists have tried to resolve.
An organism’s metabolism is defined as a set of chemical processes that occur within its cells. In order to maintain life, these processes are necessary. It is already difficult to study metabolism in modern animals, but it is even more difficult when dinosaurs are involved. These animals are already extinct. To study
dinosaur metabolism, scientists use observations of living organisms instead of direct evidence.
Animals of our era can be analogized to dinosaurs quite easily. In fact, scientists had to consider the predator-prey ratio, the dinosaur’s feeding strategy, speed, agility, activity level, bone structure, social behavior, body size, geographical distribution, the fact that dinosaurs are the ancestor of birds, blood pressure and the absence of respiratory structures and nasal cones.
