The King of the Dinosaurs just got even BIGGER! T. Rex was 50ft long and weighed up to 15 TONNES - 70% heavier than previously thought, study claims

With 60 razor-sharp teeth and jaws truthful powerful they could crush a car, nan King of nan Dinosaurs would already person been a terrifying sight.

But if that wasn't enough, nan T. Rex whitethorn person been 70 per cent heavier than antecedently thought – weighing up to 15 tonnes – according to a study.

Researchers person utilized machine modelling to look astatine nan maximum size of dinosaurs, utilizing nan celebrated T. Rex arsenic an example.

Since nan unthinkable sizes attained by galore dinosaurs make them a root of endless fascination, they raised nan mobility of really these animals evolved to get truthful big.

The squad utilised machine models to measure nan T. Rex and factored successful things specified arsenic organization size, maturation rate, lifespan and more.

The palaeontologists recovered that nan largest known T. Rex fossils astir apt autumn successful nan 99th percentile – representing nan apical 1 per cent of assemblage size – but uncovering 1 would require excavating fossils for different 1,000 years.

The machine models propose that nan largest individual that mightiness person existed could person been 70 per cent much monolithic past nan existent largest-known specimens.

If true, nan animal could person weighed up to 15 tonnes compared to nan existent weight estimates of 8.8 tonnes.

And they could besides person been 25 per cent longer, reaching 15 metres alternatively than 12.

The research, published successful nan diary Ecology and Evolution, was carried retired by a squad from Queen Mary University of London and nan Canadian Museum of Nature successful Ottawa, Canada.

Dr Jordan Mallon, 1 of nan study authors, said: 'Our study suggests that, for large fossil animals for illustration T. Rex, we really person nary thought from nan fossil grounds astir nan absolute sizes they mightiness person reached.

'It's nosy to deliberation astir a 15 tonne T. Rex, but nan implications are besides absorbing from a biomechanical aliases ecological perspective.'

Meanwhile, a abstracted study suggests that nan T. Rex whitethorn besides person boasted iron-coated teeth to thief them rip isolated their prey.

Researchers person discovered that nan serrated edges of Komodo dragons' teeth are tipped pinch iron, which whitethorn supply clues arsenic to really dinosaurs killed and ate their meals.

Dr Aaron LeBlanc, nan study's lead writer from King's College London, said: 'Komodo dragons person curved, serrated teeth to rip and tear their prey conscionable for illustration those of meat-eating dinosaurs.

'We want to usage this similarity to study much astir really carnivorous dinosaurs mightiness person ate and if they utilized robust successful their teeth nan aforesaid measurement arsenic nan Komodo dragon.

'Unfortunately, utilizing nan exertion we person astatine nan moment, we can't spot whether fossilised dinosaur teeth had precocious levels of robust aliases not.

'We deliberation that nan chemic changes which return spot during nan fossilisation process obscure really overmuch robust was coming to commencement with.'
