As if the Tyrannosaurus Rex wasn't big and scary and sharp toothy enough, scientists are now saying that they're EVEN BIGGER. Using 3D laser scans, scientists virtually weighed T-Rexes and found that those beasts weighed in 30 per cent heavier than expected.
Thirty per cent! That's a tonne! Actually, it's more than a tonne because the biggest dinosaur they weighed was the Chicago Field Museum's "Sue", which is the largest and most complete T-Rex skeleton around. That big bertha weighed in at 8.1t, which was 30 per cent more than they anticipated. Weirdly though, the smallest T-Rex they weighed was actually smaller than anticipated which means that T-Rexes grew more than twice as fast between 10-15 years old. At a growth rate of about 5kg per day, I'm guessing that means they ate a ton of little dinos.
