Yes, it is possible that some atoms or molecules in your body once belonged to a T. rex or other organisms that lived millions of years ago. The matter that makes up our bodies is constantly being recycled through various biological, geological, and atmospheric processes.

When living organisms die, their bodies decompose and the atoms that comprised them are released back into the environment. These atoms can then be taken up by other organisms over time. Carbon, nitrogen, oxygen, and other elements that were once part of a T. rex could have eventually been incorporated into plants, animals, and other organic matter, including humans.

Given the vast timescales involved and the continuous cycling of matter, it's entirely plausible that some of the atoms in your body have a long and varied history that could include once being part of a dinosaur.
