The Blasisaurus existed in Spain during the late Maastrichtian period.

This is a type of Hadrosaurid dinosaur. The Blasisaurus, or its fossil, was discovered in 2010.

Hadrosauridae were known to be herbivores, and they were found during the end of the Cretaceous age. They were nearly all over the surface of the Earth with a special focus on Asia and North America. They were also seen in Europe. Four species of Hadrosauridae were found in Europe, one of which is the Blasisaurus. Blasisaurus is a Lambeosaurine Hadrosaurid. It is unique from other dinosaurs or other Hadrosauridae in the way its dorsal edge looks like a hook. It also has a D-shaped infratemporal fenestra. These two are combined by a jugal which makes this new Hadrosaur unique. These attributes of the Blasisaurus were described in a journal called the Canadian Journal of Earth Sciences. Read on to know more awesome facts about the Blasisaurus from the Canadian Journal of Earth Sciences.

Blasisaurus Interesting Facts

How do you pronounce 'Blasisaurus'?

Blasisaurus is pronounced as 'Bla-see-saw-rus'. This name was given to this dinosaur from northern Spain as a tribute to the site where the fossil was found. This site was named Blasi 1.

What type of dinosaur was a Blasisaurus?

The Blasisaurus was a Lambeosaurine Hadrosaurid. Hadrosauridae were dinosaurs that had distinctly toothless mouths. Their snouts were long, broad, flattened, and elongated. For this reason, they are also called duck-billed dinosaurs. They were mostly herbivores. Lambeosaurine were those Hadrosauridae that were crested.

In which geological period did the Blasisaurus roam the Earth?

The Blasisaurus roamed the Earth during the late Maastrichtian age or during the second half of the Cretaceous period.

When did the Blasisaurus become extinct?

The exact history of extinction of this Lambeosaurine dinosaur remains unknown. Dinosaurs were swept off the surface of the Earth 65 million years ago after an asteroid impact.

Where did the Blasisaurus live?

Blasisaurus dinosaurs were residents of northern Spain. They were mainly found on the upper part of the Arén Sandstone or the Arén Formation. These formations were found in Arén, Catalonia, Spain. Arén no longer exists. It was on the map from the strata belonging to the late Cretaceous period.

What was the Blasisaurus' habitat?

The habitat of the Blasisaurus mainly included sandstones and limestones. These dinosaurs resided in a sand formation called Arén. This habitat was a geological formation that was a unit of the Tremp-Graus Basin.

Who did the Blasisaurus live with?

There is no information on whether this Lambeosaurine dinosaur was an animal who liked to live in herds or if it enjoyed the solitude. Hadrosauridae usually can survive both in groups as well as alone.

How long did a Blasisaurus live?

Although the lifespan of this Lambeosaurine dinosaur is not known, on average, Hadrosauridae lived for 25 years.

How did they reproduce?

Nothing specific is recorded about this Lambeosaurine dinosaur. Dinosaurs reproduced through the oviparous process. This means that they used to lay eggs which would eventually hatch into hatchlings. Dinosaurs were mammals, but unlike other mammals, dinosaurs put no effort into looking after their offspring. This prepared young dinosaurs to look after themselves even as hatchlings.

Blasisaurus Fun Facts

What did the Blasisaurus look like?

Fossils suggested that what distinguished the Blasisaurus from other Hadrosauridae was that its dentary teeth did not have any secondary ridges. The European workshop on vertebrate paleontology studies fossils of this animal, and we're able to find out more about their looks in addition to what was known from the Canadian Journal of Earth Sciences. The latter was a journal that based its studies on the partial skull that was excavated. Most of the information gathered is from this journal or from the post-cranial or partial cranial remains found of the Blasisaurus. The lower jaw was found at the Blasi 1 site.

The looks of the Blasisaurus were characterized by a jugal neck and special foramina.

How much did a Blasisaurus weigh?

The average Blasisaurus weighed 4,480-8,960 lb (2,032-4,064 kg).

What were male and female names of the species?

There are no specific names for male and female dinosaurs.

What would you call a baby Blasisaurus?

Baby dinosaurs are called nestlings and hatchlings.

How aggressive were they?

This species from Spain was not aggressive. These dinosaurs were herbivores who did not prey on other animals.

Blasisaurus dinosaurs were Hadrosauridae, so they had open habitats. Dinosaurs living in such habitats were usually not territorial or greedy about their lands.

These animals would not bite other animals since they were non-aggressive herbivores.

These animals did not have slimy skin despite them being considered reptiles. On the contrary, they had bumpy skin.

Blasisaurus dinosaurs were not colorful creatures. Like most other Hadrosauridae, they were mostly green, brown, yellow, black, or gray in color.
