Fun Dubreuillosaurus Facts For Kids

A genus of carnivorous dinosaurs, the Dubreuillosaurus generally belongs to the middle Jurassic period that spanned from the end of the Triassic period, 201.3 million years ago (mya) to the beginning of the Cretaceous period, roughly 145 mya. Only one species, the Dubreuillosaurus valesdunensis, belongs to the Dubreuillosaurus genus.

The estimated length and weight of the species are said to be around 16 ft (5 m) and 550 lb (250 kg) respectively, and these dinosaurs were 30 ft (9 m) tall. The species is best known for its low and long skull and was three times as long as it was thick. The species is now classified as a megalosaur, a large Theropoda closely related to the Megalosaur.

When it comes to history, the first fossils were found during the land restoration of the old pit of Pierre de Caen, the fragmentary skull and ribs were secured, while professional excavations started in 1998. In 2002, the species was said to be a species of the Poekilopleuron but the same notion was rejected in 2005.

Fossils also give an idea about the location and the habitat of the species. During the middle Jurassic period, most parts of Europe were covered with a number of islands. Fossils were found in sedimentary rocks that were laid in mangrove swamps and coastal areas. The dinosaur was a carnivore and used to prey on fish and several marine animals.

When did the Dubreuillosaurus become Extinct?

The first Dubreuillosaurus skeleton was discovered in France which revealed that the genus became Extinct about 168-166 million years ago. There are several theories regarding the extinction of dinosaurs. Some believed destruction was mainly caused by asteroid impact, while others state it was due to climate change, volcanic eruption, and several other natural factors.

The first fossil of the Dubreuillosaurus valesdunensis was discovered in France. In 1994, somewhere in Normandy, the fossil was discovered during restoration of the old pit of Pierre de Caen, while the fragmentary skull and ribs were secured and professional excavations started in 1998.

During the middle Jurassic period, most parts of Europe were covered with several islands.

What was a Dubreuillosaurus' habitat?

Remains of the species D. valesdunensis were found in sedimentary rocks that were laid in mangrove swamps and coastal terrains. This also affected the diet of the Theropoda species.

Who did a Dubreuillosaurus live with?

Very little is known about the behavior of the species D. valesdunensis, but like other species of the Megalosauridae family, the dinosaur must have lived in groups. It is also said that carnivore dinosaurs used to hunt fish and marine animals in groups.

How long did a Dubreuillosaurus live?

The average lifespan of the Theropoda species is not estimated as of now. Species such as the Apatosaurus, the Brachiosaurus, and the Supersaurus are known to be a few of the longest-living dinosaurs.

How did they reproduce?

The reproduction patterns were very much similar to the modern-day reptiles and Aves or birds. The Theropoda species must have used a sexual mode of reproduction to produce offspring. It is said that these creatures must have used several courtship displays to attract their potential partners.

The world's biggest dinosaur species is the Titanosaurs. Recently, fossils were found in northwest Patagonia, Argentina.

Fossils of the species have been kept in The French National Museum of Natural History.

How did the Dubreuillosaurus get its name?

The species was named Dubreuillosaurus valesdunensis in honor of the Dubreuil family.

Were they social?

Yes, several species of the middle Jurassic period – even the Dubreuillosaurus valesdunensis species – were social and used to live in small groups. Generally, carnivore dinosaurs used to form packs, just like wolves.
