New dinosaur species related to T. Rex discovered on Isle of Wight

A new species of carnivorous dinosaur has been discovered from fossilised remains found by members of the public at Shanklin, Isle of Wight last year. The four bones were examined by researchers at the University of Southampton who believe they belong to a new species of theropod dinosaur (a group of carnivorous which also include modern birds and their famous Tyrannosaurus rex).

The dinosaur has been named Vectaerovenator inopinatus which means ‘unexpected air-filled hunter’. The name refers to the curious air-filled sacs in many of the bones of the creature, in the neck, back and tail. Indeed, these structures are also found in many other theropod dinosaurs, helping scientists to identify it.

These air sacs, which act as extensions of the lungs, are also found in modern birds, which not only make the skeletons much lighter, but also ensure much more efficient breathing.

Living around 115 million years ago during the cretaceous period, Vectaerovenator was around 4 metres long, a relatively small size for Dinosaurs of this group, and although likely it would not have been the top predator, it would certainly have been an efficient carnivore, probably feeding on reptiles and small, herbivorous dinosaurs such as Hypsilophodon which was a common species at the time.

This exciting find is another example of how our understanding of prehistoric biodiversity is constantly changing with the discovery of many new prehistoric species.
