What Dinosaur Had the Longest Claws?

If you’re a dinosaur enthusiast, you’ve probably wondered about the various physical attributes of these prehistoric creatures. One question that often arises is: which dinosaur had the longest claws? The answer to this query lies in the intriguing world of the Therizinosaurus.

The Therizinosaurus: The Dinosaur with the Longest Claws

The Therizinosaurus, also known as the “scythe lizard,” holds the record for the dinosaur with the longest claws. This long-clawed dinosaur was a sight to behold, with claws measuring up to 3.5 feet (1 meter) in length.

This giant claw dinosaur roamed our planet approximately 70 million years ago during the Late Cretaceous Period. Despite its fearsome appearance, the Therizinosaurus was primarily a herbivore, using its long claws to pull down branches and leaves for consumption. However, these claws could also serve as a powerful defensive tool against predators.

Physical Attributes of the Therizinosaurus

The Therizinosaurus was a large dinosaur, with an estimated weight of five tons and a height reaching up to 20 feet (6 meters). Its most distinguishing feature, however, were its extraordinarily long claws. Each claw was attached to three elongated fingers, giving the Therizinosaurus a unique silhouette among dinosaurs.

Interestingly, the Therizinosaurus also sported feathers—a characteristic that links it to birds. This bird-like dinosaur with long claws had a beak-like mouth and a wide, bulky body. Its hind legs were robust and strong, whereas its front limbs were slender and elongated, ending in those infamous claws.

Claws in the Dinosaur World

While the Therizinosaurus had the longest claws, other dinosaurs also boasted impressive claws. The T-Rex, for instance, had sharp, curved claws to grasp and tear flesh. Raptors, on the other hand, had a large, sickle-shaped claw on each foot, primarily used for hunting.

However, none of these come close to the claw length of the Therizinosaurus. Even when compared to animals with long claws in today’s world, such as bears or big cats, the Therizinosaurus’ claw size remains unmatched.

The Therizinosaurus in Popular Culture

The Therizinosaurus has also made its way into popular culture, particularly in the Jurassic Park series. In the latest installment, Jurassic World: Dominion, a dinosaur with long claws plays a significant role. This dinosaur is none other than our clawed star—the Therizinosaurus.

Its portrayal in Jurassic World Dominion has sparked renewed interest in this clawed dinosaur. Fans are intrigued by its unique features, particularly those long claws that make it stand out from other dinosaurs in the franchise.

Discovering the Therizinosaurus

The first fossil evidence of the Therizinosaurus was discovered in Mongolia in 1948. Initially, only the enormous claws were found, leading to much speculation about what creature they belonged to. It wasn’t until later discoveries that paleontologists could piece together the full picture of this long-clawed dinosaur.

Even now, the Therizinosaurus continues to captivate us. Its long claws, bird-like characteristics, and sheer size make it one of the most fascinating dinosaurs to have walked the Earth. As we continue to learn more about these ancient creatures, who knows what other intriguing facts we’ll uncover?


When it comes to the dinosaur with the longest claws, the Therizinosaurus takes the crown. This long-clawed dinosaur serves as a reminder of the diverse and fascinating world that existed millions of years ago. So, the next time you think of dinosaurs with long claws, remember the Therizinosaurus—its remarkable features make it a standout in the realm of prehistoric creatures.
