I tried to deduce the AP amino acid DNA codon that is found in the T. rex COL1A1 sequence. I compared the codons of A and P (alanine and proline) in the painted turtle and the chicken. In both species, A was coded by TGC, and P by CCC. Therefore, it is likely that this was the same case in T. rex and other theropods, as well as early saurischians. We need to add more primitive birds and turtles to the alignment though, for better accuracy.
