The Pachycephalosaurus followed a herbivorous diet and grazed around North America during the Late Cretaceous period around 72-66 million years ago. A Pachycephalosaurus dinosaur fossil supplied a lot of information about them. Pachycephalosaurus dinosaurs had a unique head structure different from other dinosaurs.

It had a thick skull area for protecting its head and also had spikes around it. They had a beak-like mouth and inside had several teeth for ramming food.

These teeth were small in size. They had a comparatively bigger body with a long tail attached to it. It is believed that this dinosaur species also faced extinction during the Cretaceous–Paleogene extinction event.

Now, this was just the introduction part. In the article, there are more interesting and funny Pachycephalosaurus facts that will make you amazed for sure.

Pachycephalosaurus Interesting Facts

How do you pronounce 'Pachycephalosaurus'?

Pachycephalosaurus pronunciation is a bit tough. It is pronounced as 'pachy sefelo saur rus'.

Pachycephalosaurus' were comparatively smaller dinosaurs that were present in prehistoric times. They were herbivorous reptiles that inhabited the Earth during the Late Cretaceous period. They were thick bone-headed lizards that lived in North America and their specimen remains have been found in a lot of places there.

What type of dinosaur was a Pachycephalosaurus?

Pachycephalosaurus' were plant-eating dinosaurs that grazed around the continent of North America. Their fossils were found in a lot of places and according to the studies, it is seen that they were pachycephalosaurid dinosaurs. This Pachycephalosaurus dinosaur species belonged to the class of reptiles, order Ornithischia and family Pachycephalosauridae.

They also belonged to the tribe of Pachycephalosaurini. Their genus name is Pachycephalosaurus and their scientific name is Pachycephalosaurus wyomingensis. The Pachycephalosaurus skeleton remains that were found were almost complete.

In which geological period did the Pachycephalosaurus roam the Earth?

The Pachycephalosaurus wyomingensis was a herbivore reptile that inhabited Earth during the Late Cretaceous period. It was a thick-headed lizard in dinosaur history. It is roughly estimated that they inhabited Earth around 72-66 million years ago.

When did the Pachycephalosaurus become extinct?

Pachycephalosaurus fossil remains were found in the continent of North America. After studying the specimen, it was discovered that these dinosaurs inhabited this world around 72-66 million years ago in the Late Cretaceous period. It is believed that they went extinct during the Cretaceous–Paleogene extinction event.

Where did a Pachycephalosaurus live?

Pachycephalosaurus wyomingensis were terrestrial herbivore lizards that grazed around the continent of North America. Paleontologists described that they were small dinosaurs in the Pachycephalosaurid family.

What was a Pachycephalosaurus' habitat?

Pachycephalosaurus wyomingensis were small herbivorous dinosaurs in the family Pachycephalosauridae. They were found in the continent of North America. Paleontologists found several Pachycephalosaurus fossils in the regions of Montana, South Dakota, Wyoming, and Alberta. The average Pachycephalosaurus size was similar to a big cow.

Who did a Pachycephalosaurus live with?

There is no exact answer to this question, but we are can speculate! According to paleontologists, Pachycephalosaurus wyomingensis were small cow-sized herbivorous animals. It is more than likely that they were social in nature and we can assume that they lived in groups for protection against predators.

How long did a Pachycephalosaurus live?

There is no record present on how long they lived. Paleontologists assume that the Pachycephalosaurus was a dinosaur with an average lifespan range.

How did they reproduce?

If we go back to their natural history, the Pachycephalosaurus was in the family of Pachycephalosaurid dinosaurs that lived in North America. They were small reptiles that lived on land. We know that reptiles in today's world lay eggs when giving birth to their babies.

Pachycephalosaurus dinosaurs must have had done the same. They also would have had a breeding season when their species would have mated. A lot of things surrounding these animals are purely based on imagination and how they would have reproduced is one of those.

Pachycephalosaurus Fun Facts

What did a Pachycephalosaurus look like?

Pachycephalosaurus wyomingensis were pachycephalosaurid dinosaurs that lived in North America. According to the evidence found by scientists, they ate plants and roamed around in groups.

They inhabited the Earth during the Late Cretaceous period and their fossil remains were found in Montana, South Dakota, Wyoming, and Alberta in the western provinces. Pachycephalosaurus height can be compared to a full-grown cow or buffalo and it is easy to recognize them.

In height and size, they are similar to cows. Pachycephalosaurus dinosaurs are famous for their thick dome-shaped heads.

The Pachycephalosaurus head, or Pachycephalosaurus skull, has been studied thoroughly by scientists but there is not enough information or evidence available about their anatomy. Their domed head was a defensive adaptation against their predators.

This dome-shaped portion in the Pachycephalosaurus skull was around 10 in (25.4 cm) thick which successfully protected its brain part. They had spikes or bony knobs around the top of their skull and even on the nose portion. They also acted as defensive measures but were not sharp and pointed.

They had small teeth and their mouth portion was somewhat like a beak. Pachycephalosaurus skulls were small in size and were round to leaf-shaped.

They had big eyes and small noses. According to the fossils, they were mostly bipedal.

They had big legs which were strong too, while the forearms were probably small in size. The Pachycephalosaurus had a long and fat tail which contributed to its body length.

From the fossils, it is assumed that these dinosaurs that ate plants were somewhere around 14.8 ft (4.5 m) in length while their body weight was around 990 lb (449 kg). They were small but fantastic.

The Pachycephalosaurus had a strong and thick head.

How many bones did a Pachycephalosaurus have?

There is a limited amount of information available about their anatomy. We do not know exactly how many bones were there in a Pachycephalosaurus body. However, the Pachycephalosaurus is known for its dome-shaped bony head.

How did they communicate?

This is still a big mystery. The exact Pachycephalosaurus call is not yet known. Maybe they had a screeching voice or maybe had a growling voice. Maybe they had a specific call for communication. Who knows!

How big was a Pachycephalosaurus?

The Pachycephalosaurus was a thick-headed lizard species that inhabited the Earth during the Late Cretaceous period around 72-66 million years ago. This dinosaur species was bipedal and roamed in search of plants.

They had a unique skull or head, a big body, a long tail, two strong legs, and two small hands. According to fossils, their body length range was around 14.8 ft (4.5 m) and their average weight was around 990 lb (449 kg).

How fast could a Pachycephalosaurus move?

Pachycephalosaurus wyomingensis were bipedal and had strong legs. Though there is no information available on how fast they were, however we can assume that they were fast runners. Pachycephalosaurus dinosaurs were a herbivorous animal species. There was always a possibility of them being hunted by predators. They would have adapted a high speed for saving themselves.

How much did a Pachycephalosaurus weigh?

Pachycephalosaurus dinosaurs had domed heads and were grazing reptiles. They were found in western North America. They were 14.8 ft (4.5 m) long and 990 lb (449 kg) heavy.

What were the male and female names of the species?

There are no special names assigned to the males or females of this prehistoric animal species. They are commonly known as Pachycephalosaurus.

What would you call a baby Pachycephalosaurus?

Like all other dinosaur babies, baby Pachycephalosaurus dinosaurs are also known as hatchlings.

What did they eat?

According to the fossil studies, Pachycephalosaurus dinosaurs followed a herbivorous diet, meaning they were not meat-eaters. They were plant-eating reptiles that roamed around in North America. They were small in size so other carnivorous dinosaurs would have hunted them for food.

How aggressive were they?

Pachycephalosaurus' were modern dinosaurs that were herbivorous. Typically, herbivorous species are not that aggressive. They also would have had a similar behavior towards other dinosaurs.

Did you know...

The Pachycephalosaurus was found between 1859-1860 by paleontologist Ferdinand Vandeveer Hayden. Paleontologist Ferdinand Vandeveer Hayden found the fossil head of this dinosaur near the Missouri River.

Pachycephalosaurus' were head-butting dinosaurs. Head-butting dinosaurs had a strong upper head and used that strong part to attack others.

Why does the Pachycephalosaurus have a thick skull?

Pachycephalosaurus dinosaurs had a thick skull and it was most probably used as one of their defensive measures. To protect their inner head, they would have evolved into dinosaurs with thick skulls, in order to protect their delicate brain from bite damage.

Did the Pachycephalosaurus live in herds?

There is no exact information available on whether they were social or not but we can speculate. According to their specimen, they were a plant-eating small dinosaur species that had this fear of getting eaten. Now for that reason, they would have formed groups to reduce the threat of danger.
