The dinosaur Nodosaurus (Nodosaurus textilis) is a creature that comes under the category of armored dinosaurs and is a genus of Nodosaurid dinosaurs. They originated from North America during the Late Cretaceous period, which is about 95-90 million years ago in the world. The dinosaur genus Nodosaurus was found by the Hammond Foundation during a science mission called the Science Division on Isla Tacano. This is a hefty animal that weighs around 3.0-3.5 tons (2721.5-3175.15 kg) and is approx 18 ft (5.5 m) in length with a very long tail and spikes covering the sides of the body. Even having such a large body and weight, their head is very small comparatively and has a minuscule brain. These lizard-looking herbivore dinosaurs of the middle Jurassic age ate plant material only and used to live in the marsh. There is another dinosaur that often gets related to the Nodosaurs. The Ankylosaurids (family Ankylosauridae) and Nodosaurids (family Nodosauridae) are mostly recognized within Ankylosauria, which are the armored dinosaurs. But the Nodosaurids are considered more primitive than the former because they lived before the Ankylosauria. Nodosaurus vs. Ankylosaurus features are compared a lot by paleontologists. The fossil of the ancestors of the Nodosaurus, which are Nodosaurid, are found in the Middle Jurassic age in the world. But they are known to have survived the end of the Cretaceous.

Nodosaurus Interesting Facts

How do you pronounce 'Nodosaurus'?

They often get compared to the Ankylosaurids, which can be called their cousins species. Some specimens of the Nodosaur dinosaur are more than 100 million years ago, which states that they used to live around big water bodies.

What type of dinosaur was a Nodosaurus?

The Nodosaurus dinosaur is an armored dinosaur. Their defense reflexes were very good, but neither the immunity nor the lifespan was good. They used to live in very little space as compared to other dinosaurs. This herbivore Jurassic age animal ate plants and grasses.

In which geological period did the Nodosaurus roam the earth?

The North America Nodosaurus used to live in the Late Cretaceous period, which was about 90-95 million years ago. The ancestors of this herbivorous dinosaur were present in the middle Jurassic period. They existed from Cenomanian Age to Maastrichtian Age in history. The fossil and remains of the skeleton mainly got discovered in Alberta in the whole world.

When did the Nodosaurus become extinct?

The dinosaur Nodosaurus (Nodosaurus textilis) of the family Nodosauridae and genus Nodosaurus became extinct around 110 million years ago. It is believed that they became extinct due to natural disasters.

Where did a Nodosaurus live?

Nodosaurus are the dinosaurs that used to inhabit the parts of the United States of America and also some parts of Europe too. They mostly inhabited the areas the warm or tropical areas and sometimes marsh areas too where they can get good rainfall. Kansas, Wyoming, and Alberta (Canada).

Nodosaurus Fun Facts

What did a Nodosaurus look like?

This dinosaur the phylum Chordata, clade Dinosauria, Order Ornithischia, Suborder Ankylosauria, and Subfamily Nodosaurina, is a 13.12-19.68 ft (4-6 m) long ornithischian dinosaur. They have very interesting features as compared to many dinosaurs discovered in history. They had bony plates on top of its body covering the whole area of the top and the spikes covering the sides of the body. These plates were arranged in bands over the ribs and has wide plates too. These wide plates are covered in bony nodules which are regularly arranged. They had four very short legs and five-toed feet with a long stiff, short neck and a clubless tail. The head was both small and narrow and had a pointed snout with powerful jaws and small teeth. This ensures the fact that these animals used to feed on just plant material and easily chewable foliage because their small teeth were unable to chew flesh or meat. This dinosaur was a member of the Ankylosaur family and weighed three tonnes. They lived in the middle Jurassic age and are considered as one of the founders of the armored dynasty of the dinosaurs which later got split into two different families.

These lizard-like looking dinosaurs used to protect themselves by their distinctive back and the spikes on them from the predators.

How many bones did a Nodosaurus have?

The exact number of bones in the Nodosaurus skeleton is not known yet. But their cousin species of Ankylosaurids dinosaurs had a clublike tail made of seven bones fused together into a hard and heavy mass. The Ankylosaurids existed for a comparatively larger duration of time than these dinosaurs and hence the Nodosaurus are considered as primitive.

There is not much information available on the communication ways of this dinosaur. But this dinosaur used to form small groups with other dinosaurs of similar armor features like Ankylosaurus, Polacanthus, and Crichtonsaurus to defend their territory and display their strength.

How big was a Nodosaurus?

The length of the Nodosaurus of clade Dinosauria was about 13.12-19.68 ft (4-6 m). They were approx double the length of the Amazonian manatee. The largest herbivore dinosaur the "Titanosaur" Argentinosaurus huinculensis" was about 118 ft (36 m) in lenght.

How fast could a Nodosaurus move?

They were heavyweight dinosaurs and because of that, their running speed was very less as compared to other lightweight dinosaurs. They are also called lizard-looking dinosaurs like the relative species of the Ankylosaurids and also resembles the saltwater crocodile in terms of spikes, but the latter has smaller. The bone count of the discovered skeleton is not known.

The weight of the Nodosaurus was about 3.0-3.5 tons (2721.5-3175.15 kg) and they are 30 times heavier than the dusky dolphins. Because of their heavyweight and short legs they weren't able to move very fast or run in the presence of the danger of any predators and hence used to use their armored backs for defense.

But when a larger predator like a tyrannosaur flips this dinosaur, then they will become defenseless.

Did you know...

To protect themselves from the predators, these Nodosaurs dinosaurs used to completely rely on the thick bony plates coat and knobs that used to cover their back. The legs on the front were very small as compared to their large size.

Nodosaurids did not have the tail club of the ankylosaurids and the skulls were also very not so small and had a protective plates layer. They are also not considered as intelligent species of dinosaurs and are the best-preserved dinosaurs ever found.

How did the Nodosaurus die?

The specimen of the Nodosaur dinosaur, which was found in Alberta, Canada, gives the idea that these animals used to live near small or medium-sized water bodies. The specimen is the oldest recorded and scientists are of the opinion that these dinosaurs must have died near the water either by the predator animals like theropods or sauropods or by the natural calamities like floods and tsunamis.

Who discovered the Nodosaurus?

The discovery of these dinosaurs took place in the countries of the United States of America and Canada. Even some of the population also got recorded in Europe but on a comparatively minor scale than that of the USA and Canada. Kansas, Wyoming, and Alberta are some regions where the Nodosaurus fossil of this animal was found the most by paleontologists.

One of the first few Nodosaurus fossils of these armored dinosaurs was found in North America by the Hammond Foundation when they were finishing up their Science Division Mission on Isla Tacano.
