I have plans for a new thread, which is where a virus appears and changes the course of evolution and history. It is called Asian-South American Exclusion.
I read your story involving Troodon's survival after the Cretaceous extinction. I enjoyed it so much that I made my own ASB story about if 4 dinosaur species survived. It is called "Dinosauroid" by me, All Rounder. You should check it out!
Question: When will you finish your Troodon story?
