A study by three US researchers revealed that T. rex didn't reach their full adult size until around age 40, maturing gradually and steadily over decades rather than stopping abruptly earlier in life. This means the oldest T. rex likely lived well beyond their 40s, enjoying a prolonged 'adolescence' where they kept getting bigger and stronger into middle age. Before this study, experts believed T. rex stopped growing by age 25, based on earlier counts of bone growth rings that suggested a quicker path to maturity.
