Wow really... This is proof that dinosaurs are still alive. Obviously that is not a fish and it's not evolving into a dinosaur.

It still sounds as if you are talking micro evolution.

This reminds me of a National Geographic magazine that I looked at when I was kid. It portrayed drawings of what dinosaurs looked like if they had evolved. It showed a raptor then morphed thru time to look like a reptilian humanoid. Even at that age I relalized it was wrong.

The difference is that it isn't the same as a horse. It was its own species that died out. No, I'm not a biologist. I simply don't believe in macro evolution. Micro evolution exists and that has been proven. You aren't the first person to try and scientifically prove macro evolution to me. I really respect your opinions. I just don't agree with them.

Sarcosuchus is not a modern croc. It is an extinct form that was selected for eating large lungfish from Northern Africa ~100mya. Again, these animals did not just show up. At one time we do not see a single modern croc family. Then, over time, you see animals that accumulate more and more modern like traits until you get modern families, and even then you do not have modern species until relatively late...

The only way that I can see a new species arise from another is thru hyrbridization. The mating of two unrelated species to produce a new one. Look at the example of the rubic cube as the genes of a dog. There is only so much room for variation and survival. Horses and Donkeys are still equines. Some mules have been found to be fertile.

Yes they do. The fossils that have been found were huge. The ancient crocs were over 40 ft long. These wide ranging morphology branches are only speculation and not conclusive.

Oh, by the way, those pig organs have usually been modified so they we express human-like antigens on the surface of their cells to reduce rejection...

No one said we are supposed to be able to cross them. Chromosomal aberrations take hold in separated populations that can spread in local populations until their ability to cross with others is reduced. In horses and donkeys only a few regions have flipped but this has reduced their ability to interbreed long term...
