T. rex took 40 years to reach full size, scientists find
A new study analyzing 17 tyrannosaur fossils suggests T. rex took about 40 years to reach its full size of eight tons, extending previous estimates by 15 years. Researchers identified hidden growth rings in fossil bones using advanced techniques and found that some well-known T. rex fossils may actually belong to different species. The findings provide the most detailed reconstruction of T. rex growth patterns to date.
Scientists found that T. rex took about 40 years to reach full size, based on growth rings in fossil bones.
This changes previous beliefs about how fast T. rex grew and suggests some famous fossils may not be T. rex at all.
The study shows how new research methods can reveal surprising details about ancient life, helping us better understand prehistoric ecosystems.
