While the mighty Tyrannosaurus Rex is rightly recognised as being among the most fearsome of carnivorous dinosaurs, in recent years an even larger beast - the spinosaurus - has begun to attain a similar level of infamy.

A new study by a team of researchers at Portsmouth University confirms the spinosaurus “was an enormous river-monster”, which would have terrorised riparian species.

This extraordinary dinosaur could grow to 50 feet (15 meters) long and weigh seven tons - making it even longer than the T-Rex, which could grow to 40 feet (12 metres) long.
