This is a copy from the old forum that might be relevant for the discussion.

Yeah, I think creating dino mitochrondria won't be a problem. The order of the genes looks quite similar already.

This is the order of the turtle mtDNA. I just have to store it somewhere.


 * D-loop
 * F
 * 12S
 * V
 * 16S
 * L
 * NADH1
 * I
 * Q
 * M
 * NADH2
 * W
 * A
 * N
 * C
 * Y
 * COI
 * S
 * D
 * COII
 * K
 * ATP8
 * ATP6
 * COIII
 * G
 * NADH3
 * R
 * NADH4L
 * NADH4
 * H
 * S
 * L
 * NADH5
 * NADH6
 * E
 * Cyt b
 * T
 * P

All three groups have the same set of 15 genes, and almost in the same order. Somewhere in the dinosaur evolution the Cyt b-T-P and NADH6-E segment switched places. We will never know when this happened.

Turtle and bird both have an F region after the D-loop, only in crocs that region is move to another place. I think dino's had the F region after the D-loop. Furthermore, turtles and birds both have a H-S-L region, only in crocodiles this is region is reordered into S-H-L. I think dino's had a H-S-L region.

Because of this, I think it is better to compare ostrich and turtle DNA. Crocs seemed to have changed a lot when they branched off.

I wonder if it will matter anything if we would give all dinosaurs mitochochondria with the bird gene order.
