The dinosaur was named after a native tribe Regni that lived at Sussex in England in the past. Previously, these dinosaurs were related to armored dinosaurs and in 1888 the genus was classified under Scelidosauridae. Later it was concluded the dinosaur is closely related to another genus called the Huayangosaurus. This makes the Regnosaurus a part of the Huayangosaurid clade. There were many other theories regarding a classification of Regnosaurus, one of which stated the Regnosaurus might be a Sauropod. Other paleontologists suggested that the Regnosaurus was synonymous with the Hylaeosaurus. Many recent researchers consider the Regnosaurus specimen to be a nomen dubium because of the absence of enough fossils.

At first, the Regnosaurus was identified as an Iguanodon from its lower jaw structure and presented as the same to the Royal Society. This identification was challenged after the discovery of several real jaws of the Iguanodon and immediately it was allocated to a new genus called Regnosaurus.

Regnosaurus Interesting Facts

How do you pronounce 'Regnosaurus'?

The name Regnosaurus is pronounced as 'Reg-noe-sore-us'.

What type of dinosaur was a Regnosaurus?

First observed as an Iguanodontid, the Regnosaurus belonged to the family of herbivorous dinosaurs called Stegosaur that was prevalent during the early Cretaceous period.

In which geological period did the Regnosaurus roam the Earth?

The Regnosaurus lived during the early Cretaceous period in the region which is presently known as England. Very few fossil remains of the dinosaur make it a nomen dubium genus.

When did the Regnosaurus become extinct?

The species of Regnosaurus became extinct by the late Cretaceous period.

Where did the Regnosaurus live?

Regnosaurus fossils were discovered from Sussex in southern England along with fossils of the Iguanodon excavated from the strata of Tilgate Forest. They were found near Cuckfield and are presently preserved in the British Museum of Natural History.

What was the Regnosaurus' habitat?

The Regnosaurus was a terrestrial dinosaur and lived on plain lands.

Who did the Regnosaurus live with?

The Regnosaurus is known from only a few remains; whether it lived singly or herded together to defend itself from predators could not be determined.

How long did a Regnosaurus live?

The Regnosaurus lived during the early Cretaceous period but the time period during which the genus lasted is uncertain.

How did they reproduce?

The Regnosaurus reproduced by laying eggs like all other dinosaurs.

Regnosaurus Fun Facts

What did the Regnosaurus look like?

The Regnosaurus northamptoni is a poorly described species whose evolution could not be traced properly. Neither the skull of the animal has been discovered, nor its teeth. They are only known for their partial lower jaw structure which makes it a nomen dubium of England. It is not known if they had neck frills.

The period which the Regnosaurus existed is unknown.

How many bones did a Regnosaurus have?

The total number of bones present in the body of a Regnosaurus is unknown. The species of the genus is proven to be nomen dubium due to the absence of enough fossil remains. Only a partial lower jaw of the dinosaur has been discovered.

How did they communicate?

The Regnosaurus communicated using vocalizations like all other dinosaurs.

How big was the Regnosaurus?

In the past, it was estimated from the partial lower jaw remains that the length of the Regnosaurus was about 13 ft (4 m). These dinosaurs were shorter than Vitakridrinda dinosaurs.

How fast could a Regnosaurus move?

In science, it is not possible to determine the speed of an animal from its fossilized jaws. Therefore, its speed has not been determined.

How much did a Regnosaurus weigh?

The bodyweight of the Regnosaurus dinosaur could not be determined from the lower jaw structure.

What were male and female names of the species?

Male and female Regnosaurus dinosaurs did not have particular names; both genders were called Regnosaurus.

What would you call a baby Regnosaurus?

A baby Regnosaurus is known as a hatchling or nestling.

How aggressive were they?

The Regnosaurus was an herbivore in nature, and was not as aggressive as flesh-eating predators of the early Cretaceous period. It is not known how these dinosaurs defended themselves.

Did you know…

The type species was named in honor of the second Marquess of Northampton, Spencer Crompton, who was also the president of the Royal Society. The word northamptoni is derived from the word Northampton.
