Fun Dubreuillosaurus Facts For Kids
Gallery
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.
