One of the last species of Dinosaurs to survive long after the asteroid impact was a species of raptor dinosaurs called Troodon which paleontologists atribute to their intelligence, their non specialized omnivorous diet and the fact that they were feathered allowing them to weather down the post impact winter, but for one reason or another even they didn't make it. So what if, they did manage to survive and evolve into intelligent dinosauroids would it still be possible for mammals to evolve the way they did in otl and eventually with humans? They don't necessarily have to be as smart as humans, or even outmatch them in reporduction and population, would it be possible? In 1982, Dale Russell, then curator of vertebrate fossils at the National Museum of Canada noted that there had been a steady increase in the encephalization quotient or EQ (the relative brain weight when compared to other species with the same body weight) among the dinosaurs. Physically they had all the makings of evolving into human like creatures, binocular vision, partially opposing thumbs, bipedal. With the extinction of the bigger dinosaurs, I think its possible for humans to also evolve. So ignoring the fact that they still might have preyed on the early rat like mammals to crawl out of their holes, or the fact that Troodon might have gone extinct at some other future time and fastforwarding to the present, what might the world look like with humans and troodontid dinosauroids populating the earth.
