Take a trip back in time, long before humans walked the surface of the Earth. To an age when astonishing and distinct creatures existed. It was a time rich with life that saw some of the most fascinating predators that the Earth has ever known. Each predator was uniquely adapted to its environment. Whether in deep, cool oceans or high prehistoric skies, both distinct and often surreal, they forged their individual places.
However, a few of the previous amazing prehistoric hunters are also on this list, and they can mostly be at the top of their food chains. These were the titans, the greatest killing machines that brought fear into every creature’s mind, and they were referred to as the biggest carnivorous dinosaurs. Let’s explore the amazing things about these huge predators, reveal their secrets, and learn about the massive stories of their kingdoms.
Here are the Top 15 Biggest Carnivorous Dinosaurs:
The Jurassic period was dominated by many robust meat-eating predators. They ruled the era by being at the top of the food chain by invoking fear among others. Here’s a list of the largest meat-eating dinosaurs who landed the top tier of the list:
1. Spinosaurus

Weight: 22 tons
Period: Late Cretaceous Epoch
2. Giganotosaurus

Period: Late Cretaceous Epoch
4. Tyrannosaurus Rex

The iconic “tyrant lizard king” of North America, T. rex, was a powerhouse with an incredibly strong bite force capable of crushing bone. Its relatively large brain and keen sense of smell made it a highly effective predator and scavenger.
Height: 42.7 feet
Weight: 8–9 tons
Period: Upper Cretaceous period
5. Bahariasaurus

An enigmatic and similarly massive theropod from North Africa, Bahariasaurus lived alongside Carcharodontosaurus and Spinosaurus. While its exact form is still debated due to limited fossil remains, it was undeniably among the largest carnivorous dinosaurs of its time.
Height: 13 ft
Weight: 5–6 tons
Period: Late Cretaceous period
6. Chilantaisaurus Tashuikouensis

This massive theropod, an early contender among the huge carnivorous dinosaurs, was a formidable hunter from the Late Cretaceous of Asia, known for its powerful build and potentially high speed.
Height: 12–13 ft
Weight: 4–5 tons
Period: Mid Cretaceous
7. Deinocheirus

Though initially thought to be a gigantic predator, Deinocheirus was a fascinating omnivore, proving that not all large theropods among the enormous carnivorous dinosaurs were exclusively meat-eaters, with its distinctive long arms and duck-like snout.
Height: 16 ft (due to massive arms and back)
Weight: 6.5 tons
Period: Late Cretaceous period
8. Carcharodontosaurus Iguidensis

Hailing from Late Cretaceous North Africa, this species of Carcharodontosaurus was a truly colossal predator, easily ranking among the biggest carnivorous dinosaurs with its serrated, shark-like teeth perfect for slicing flesh.
Height: 12 ft
Weight: 4–5 tons
Period: Late Cretaceous Epoch
9. Siats Meekerorum

Discovered in North America, Siats meekerorum was a terrifyingly large carcharodontosaur, filling the role of an apex predator before the tyrannosaurs, and firmly placing it within the league of the largest carnivorous dinosaurs.
Height: 11 ft
Weight: 4 tons
Period: Early Cretaceous
10. Acrocanthosaurus

This fearsome Jurassic predator was a robust and powerful hunter, reaching lengths of up to 33 feet. It was among the largest carnivorous dinosaurs of its time in North America and Portugal, armed with serrated teeth for tearing flesh.
Height: 10–11 ft
Weight: 3–4 tons
Period: Late Jurassic epoch
12. Yangchuanosaurus

Hailing from Late Jurassic China, Yangchuanosaurus was a massive theropod dinosaur, similar in size and appearance to Allosaurus. With a large head and powerful jaws, it was the apex predator of its ecosystem, truly one of the largest carnivorous dinosaurs of Asia.
Height: 10 ft
Weight: 3 tons
Period: Late Jurassic epoch
13. Tarbosaurus

A close cousin of the famous T. Rex, Tarbosaurus was a formidable hunter from Late Cretaceous Asia. Reaching lengths of 30-40 feet, it possessed a massive skull and incredibly powerful jaws, cementing its status among the largest carnivorous dinosaurs.
Height: 10 ft
Weight: 4–5 tons
Period: Late Cretaceous Period
14. Allosaurus

What These Dinosaurs Tell Us About Prehistoric Ecosystems?
These extensive dinosaurs were important apex predators that changed the prehistoric food chain. These megafauna would regulate herbivore numbers as well as smaller carnivores. Their fossil records range over great distances, with examples of Tyrannosaurids in North America and Asia, and examples of Carcharodontosaurids in Africa and South America, indicating a global presence. This presence led to evolutionary arms races where both predator and prey developed increasingly specialized adaptations as prey improved their defense, making it a never-ending cycle of diversification and mega-expansion in size for these incredibly large theropods.
Conclusion
The huge Spinosaurus and powerful T. rex are the biggest carnivorous dinosaurs that are at least myths. They were very important players in prehistoric ecosystems. They were the highest apex predators in their ecosystems. There are records of the global distribution of carnivorous dinosaurs, and they were being selected in an evolutionary arms race, both of which affected the development of ancient life. Exploring their world helps us understand that dinosaurs were not just giants of our imagination but solidified a place in our planet’s history.
FAQ:
1. What was the biggest carnivorous dinosaur ever?
The title of “biggest carnivorous dinosaur” is often debated, but Spinosaurus is generally considered the longest, while Tyrannosaurus Rex is considered the heaviest. Spinosaurus is estimated to have been the longest, potentially reaching up to 18 meters in length.
2. Who is bigger, T Rex or Giganotosaurus?
Then there’s the weight comparison. At up to 9 tons (8.2 metric tons), T. rex was among the heaviest theropods — a true tank among predators. Giganotosaurus was even heavier still, maxing out at around 14 tons (12.7 metric tonnes).
3. Would a Spinosaurus beat a Rex?
In a battle between a Spinosaurus and a Tyrannosaurus Rex, the T-Rex would likely win, especially on land. While the Spinosaurus was a large and powerful dinosaur, its adaptations leaned more towards aquatic hunting, and it would be at a disadvantage against the T Rex in a terrestrial fight.
