Tyrannosaurus rex might have been 70% heavier than previously thought and 25% longer, researchers suggest.

The largest T. rex that could have existed may have been significantly larger than the current largest-known specimen, weighing in at an estimated 15 tonnes instead of 8.8 tonnes, and measuring at 15 metres instead of 12 metres, according to the study.
