Unraveling the Mysteries of Ankylosaurus: Size, Height, Weight, and More

The world of dinosaurs is filled with fascinating creatures, but few are as intriguing as the Ankylosaurus. Known for its armored body and club tail, this dinosaur has captivated the interest of paleontologists and dinosaur enthusiasts alike. In this article, we will delve into the size, height, weight, and other fascinating details about this prehistoric creature.

Ankylosaurus: The Armored Dinosaur With a Club Tail

Belonging to the family Ankylosauridae, the Ankylosaurus is often referred to as the ‘dinosaur with a club tail’. This description stems from its most distinct feature – a large club-like structure at the end of its tail, which was likely used for defense against predators.

The name Ankylosaurus means ‘fused lizard’, a reference to the heavy armor that covered its entire body, including the top of its head and even its eyelids. These bony plates, known as osteoderms, made it one of the most well-protected dinosaurs, earning it another nickname – the ‘armored dinosaur with a club tail’.

Ankylosaurus Size and Height: A Comparative Analysis

One of the most frequently asked questions about the Ankylosaurus revolves around its size and height. How big was the Ankylosaurus? To answer this, let’s look at some fossil evidence.

Fossil records suggest that an adult Ankylosaurus could reach lengths of up to 20-30 feet (6-9 meters) and stood about 5.6 feet (1.7 meters) tall at the hips. In terms of size comparison, this would make the Ankylosaurus roughly as long as a school bus and about as tall as an average adult human.

However, it’s important to note that these measurements are estimates based on incomplete fossil evidence. The actual size and height of the Ankylosaurus could have varied.

Ankylosaurus Weight: A Heavyweight Champion

Given its considerable size and the presence of heavy armor, it’s no surprise that the Ankylosaurus was a heavyweight among dinosaurs. It’s estimated that a fully grown Ankylosaurus could weigh between 6 to 8 tons (12,000-16,000 pounds). That’s about the weight of two modern-day elephants!

When and Where Did the Ankylosaurus Live?

The Ankylosaurus roamed the Earth during the Late Cretaceous period, approximately 68 to 66 million years ago. Fossil records indicate that they lived in what is now western North America.

Herbivore or Carnivore: What Did the Ankylosaurus Eat?

Despite its intimidating appearance, the Ankylosaurus was a herbivore. Its diet likely consisted of low-growing plants, which it would have grazed with its small, leaf-shaped teeth.

Ankylosaurus Speed: Not Built for Racing

With its heavy armor and short legs, the Ankylosaurus was not built for speed. While we don’t have exact figures, it’s safe to say that the Ankylosaurus was likely a slow-moving creature, relying more on its protective armor than speed to evade predators.

Dinosaurs Similar to Ankylosaurus

There were several dinosaurs similar to Ankylosaurus, including Euoplocephalus, Nodosaurus, and Edmontonia. These dinosaurs, like the Ankylosaurus, were part of the Ankylosauridae family and featured similar body armor and club-like tails.


The Ankylosaurus is a testament to the incredible diversity of dinosaur life. From its size and weight to its armored body and club tail, every aspect of this creature sparks intrigue. As we continue to uncover more fossils and learn more about these remarkable creatures, who knows what other fascinating details we will discover about the Ankylosaurus?
