I picture flightless birds that just don't need arms. I suspect they keep their wings for balance since they don't have a tail like t-rexThe evolution of dinosaurs that have lasted for millions of years, I would like to understand why the T-Rex to keep his little Arms in front of the rest of his body who has become huge as for the rest of the dinosaurs.?
Here is one of the first T-rex: Nanotyrannus
