Burianosaurus was an ornithopod dinosaur that lived approximately 100.5 million years ago during the Cenomanian stage of the Late Cretaceous period. This dinosaur holds special significance as the first validly named dinosaur species from the Czech Republic, representing an important milestone in Central European palaeontology.
The dinosaur lived in what is now the Czech Republic during a time when the region had a warm, tropical climate with lush vegetation. As an ornithopod, Burianosaurus was a plant-eating dinosaur that likely fed on ferns, cycads, and early flowering plants that were becoming more common during the mid-Cretaceous period. It probably moved on both two and four legs, switching between bipedal locomotion when moving quickly and quadrupedal stance when feeding on low-growing vegetation.
Unfortunately, our knowledge of Burianosaurus remains limited because it is known from only a single fossil - a thigh bone (femur) discovered in 2003. This fragmentary evidence makes it difficult to determine the dinosaur's exact size, appearance, and relationships to other ornithopods, though scientists estimate it was a medium-sized dinosaur, possibly similar to other iguanodont-like ornithopods of its time.
The genus name honours Zdeněk Burian, a famous Czech palaeoartist whose beautiful dinosaur illustrations helped bring prehistoric creatures to life for generations of dinosaur enthusiasts. The species name, augustai, commemorates Czech palaeontologist Josef Augusta, highlighting the important contributions of Czech scientists to our understanding of prehistoric life.
What made Burianosaurus distinctive?
Due to being known from only a single femur bone, specific distinguishing features of Burianosaurus cannot be determined with certainty. The thigh bone suggests it was a medium-sized ornithopod with robust leg bones typical of plant-eating dinosaurs that could move on both two and four legs.
Behaviour
Based on its classification as an ornithopod, Burianosaurus likely lived in herds and spent much of its time foraging for plant material. It probably alternated between walking on four legs whilst feeding and running on two legs when escaping from predators or moving between feeding areas.
Burianosaurus FAQ
What did Burianosaurus eat?
Burianosaurus was a herbivore that fed on the plants available in
Late Cretaceous Czech Republic, including ferns, cycads, conifers, and the newly evolving flowering plants. As an ornithopod, it would have had a beak-like mouth perfect for cropping vegetation and cheek teeth for grinding plant material.
How big was Burianosaurus?
Based on the single femur bone discovered, scientists estimate Burianosaurus was roughly 6 metres long, stood about 2 metres tall at the hip, and weighed approximately 2 tonnes. However, these estimates are uncertain due to the limited fossil evidence.
When did Burianosaurus live?
Burianosaurus lived during the Cenomanian stage of the
Late Cretaceous period, approximately 100.5 million years ago. This was a time when flowering plants were becoming more diverse and dinosaurs were approaching their peak diversity.
Where was Burianosaurus found?
Burianosaurus was discovered in the Czech Republic, specifically in rock layers belonging to the Peruc-Korycany Formation. The fossil was found in 2003 and represents the first validly named dinosaur from the Czech Republic.
How do you pronounce Burianosaurus?
Burianosaurus is pronounced 'bur-ee-AH-no-SORE-us'. The name can be broken down into syllables as Bu-ri-a-no-sau-rus, with emphasis on the 'AH' and 'SORE' sounds.
What does Burianosaurus mean?
Burianosaurus means 'Burian's Lizard'. It was named in honour of Zdeněk Burian, a celebrated Czech palaeoartist famous for his realistic dinosaur paintings. The species name 'augustai' honours Czech palaeontologist Josef Augusta.
How fast could Burianosaurus run?
The running speed of Burianosaurus is unknown due to the limited fossil evidence. However, as an ornithopod, it likely could switch between walking on four legs and running on two legs when necessary, though specific speed estimates cannot be made from a single thigh bone.
What type of dinosaur was Burianosaurus?
Burianosaurus was an ornithopod dinosaur, part of a group of herbivorous dinosaurs that included famous species like Iguanodon and Parasaurolophus. Ornithopods were characterised by their ability to walk on both two and four legs and their specialised plant-eating adaptations.
Was Burianosaurus related to birds?
No, Burianosaurus was not closely related to birds. As an ornithopod, it belonged to the ornithischian group of dinosaurs, whilst birds evolved from theropod dinosaurs in the saurischian group. However, all dinosaurs, including Burianosaurus, share a common ancestor with birds.
How many Burianosaurus fossils have been found?
Only one fossil of Burianosaurus has been discovered - a single femur (thigh bone) found in 2003. This limited fossil evidence makes Burianosaurus a 'nomen dubium', meaning its classification and characteristics remain uncertain until more complete remains are found.
