Good questions. It is fine that you ask questions.

If you compare the genes of birds, you can only calculate the sequence of the common ancestor of all birds that lived somewhere in the Jurassic of Triassic. T. rex isn't part of that line.

But I have to look at the genes. Maybe the gene has evolved that much. I wanted to cover that in Filling the sequence gaps.

However, the genome sizes of all theropods seems to imply that the theropod genome didn't evolve that much.

The archosaur gene functioned perfectly in monkey cells. Indicating that the mutations in the gene gene of the last 300 million years didn't affected its function. So, it could be that a T. rex with a chicken gene was perfectly healthy.
