Dinosaurs that Could Kill Therizinosaur

Introduction to Therizinosaur Dinosaur

The Therizinosaur dinosaur, which is one of the most mysterious creatures ever to walk the Earth, first appeared in the late Cretaceous period approximately 70 million years ago. It is one of the earliest members of the group Therizinosauridae, the family of theropods that includes the iconic theropods such as Tyrannosaurus rex, Velociraptor, and Deinonychus. This large, ostrich-like dinosaur is distinctively marked by an imposing skull and a unique set of claws that could reach upwards of three feet in length!

Therizinosaur had a special suite of adaptations that made it successful. It was an herbivore with a long neck and small head, and it had powerful legs and large claws that aided in feeding, defense, and predator evasions. Its long tail may have aided it in making large sweeping turns in order to escape danger or to quickly turn and face a potential threat.

When it comes to which dinosaurs could have killed the Therizinosaur, there are many possibilities. From fierce predators to other large herbivores, any of these dinosaurs would have been capable of successfully taking down a Therizinosaur in a fight. So let’s dive into which dinosaurs could have killed the Therizinosaur.

Therizinosaur Dinosaur

Tyrannosaurus Rex

The king of the dinosaurs, Tyrannosaurus Rex, is probably the top contender for which dinosaur could have killed the Therizinosaur. This massive predator was the largest carnivore of its time and could reach lengths up to 40 feet long, with a weight of up to 7 tons. It had a massive head with powerful jaws and razor-sharp teeth that could easily have ripped apart a Therizinosaur with ease.

However, the Therizinosaur’s powerful claws could have given it an advantage in fighting a T-Rex. With its long claws, the Therizinosaur could have been able to effectively counter the T-Rex’s bite and inflict serious injury to the Carnivore.


The Spinosaurus was another giant predator of the Cretaceous period, and it was slightly larger than the T-Rex, averaging between 43 and 50 feet in length and weighing up to 8 tons. It was distinctively marked by its sail-backed body and long, flat snout filled with sharp teeth, which made it perfect for catching and eating large prey.

In a fight between the two, the Spinosaurus could have inflicted serious damage on the Therizinosaur. Its long, flat snout was perfect for snatching and tearing the Therizinosaur’s flesh and it could have made use of its tail, which was a formidable weapon, to swat and possibly knock down its prey.


Deinonychus was a smaller carnivore that evolved during the late Cretaceous period and was around the same size as the chicken. It averaged between 6 and 7 feet in length and weighed up to 110 pounds. Its unique feature was its long hind, feet which enabled it to jump and slash its prey.

Deinonychus would have been a deadly threat to the Therizinosaur. Its small size would have enabled it to remain hidden and approach the Therizinosaur secretly. It could then have mounted a surprise attack, slashing at the Therizinosaur with its sharp claws and teeth.


Ankylosaurus lived during the late Cretaceous period and, like the Therizinosaur, it was an herbivore. It was much larger than the Deinonychus, averaging between 23 and 33 feet in length and weighing up to 7 tons. It was notable for its massive club-like tail and its elephant-like skin, which was covered in bony plates and knobs.

Ankylosaurus would have been a formidable opponent for the Therizinosaur. Its massive bony plates and tail could have been used to effectively defend against the Therizinosaur’s long claws, and it could have used its club-like tail to inflict serious damage on the Theriosaur.


Triceratops was a large herbivore that lived during the late Cretaceous period and was around the size of an elephant. It averaged around 30 feet in length and weighed up to 8 tons. It was distinctively marked by its large horns and powerful neck, which it could use to defend itself against predators.

In a fight against the Therizinosaur, Triceratops could have been at a slight disadvantage because it was slightly smaller than the Therizinosaur. However, its horns and powerful neck could have enabled it to counter the Therizinosaur’s claws and inflict serious wounds on its opponent.


There are many different dinosaurs that could have posed a threat to the Therizinosaur. From massive predators like the T-Rex and Spinosaurus to powerful herbivores such as Ankylosaurus and Triceratops, any of these dinosaurs would have been capable of successfully taking down a Therizinosaur in a fight. With its impressive claws and other adaptations, the Therizinosaur could have given any of its would-be predators a serious challenge.

Ultimately, it’s impossible to know for certain which dinosaur could have killed a Therizinosaur, but one thing is for sure – the Therizinosaur was one of the most formidable creatures ever to walk the Earth and would have been a tough adversary for any of its would-be predators.
