Why do they say that the tyrannosaurus rex is a long ancient ancestor of modern day chickens? (lemmy.world)

Did they determine this by comparing what DNA fragments they've managed to recover, or by physical skeletal structure similarities, or what?

I'm no expert in the field, but I just don't see it.

The best evidence for their common ancestry is from 2008, but it doesn’t look like there have been any new developments since then.

Molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein — along with that of 21 modern species — confirms that dinosaurs share common ancestry with chickens, ostriches, and to a lesser extent, alligators.
