You need to read the post again. He didn't say dinosaurs. He said something
similiar. He also presummed a similar planet to develop on. The constrants
on what is possible suggests that many of the life forms that arise might
bear a passing resemblance to something that lived on this planet at one
time if metazoians arose in the first place.

Are there other options? Of course. Metazoans might not develope.
Vertibrates might not develope. It is very unlikely that the resemblance
would be more than something similar.

On the othe hand the largest rhino that ever lived was a lot like a
sauropode. That doesn't mean it was one or shared an LCA in the last
250,000,000 years. A mole cricket is similar to mole. A wood louse to a
triolbite, etc. I have a lot of respect for form follows fuction putting out
organisms that resemble each other.
