Except the Allosaurus was long gone by then. Weren't the Carnosaurs replaced by Coelurosaurs by the early Cretaceous?Flagg wrote:Velociraptors weren't even in that part of the world 85 million years ago (they weren't even around 85 million years ago) assuming the portal takes them to roughly the same geographical area (Chicago). This is supported by mention of North American species such as Allosaurus being mentioned.
Since they believe it to be a different timeline, I wonder if they're giving any thought to trying to gently engineer the ecology to be more amenable to humans. In fact, wouldn't they just about have to introduce modern bees to engage in intensive agriculture? I know there were a few flowers by that point, but there weren't many specialized pollinators then were there? Had flowers even spread to North America yet?
It seems to me they could plant various fruit and nut trees and release lots of species of bees without causing an immediate ecological disaster.
I can see them being afraid to bring swine back, but chickens don't usually become invasive pests. Feral dogs cannot survive well without human garbage to scavenge from. Aside from ethical and aesthetic concerns, would a controlled local extinction of indigenous flora and fauna really be so terrible? The mere presence of the humans is going to create new selective pressures.
One thing that bothers me is the aggressiveness of the predators. Even if they're not as intelligent as mammals, crocodiles and monitor lizards can still learn. I would think the big predators would learn quickly enough that the vehicles are not good prey items and the settlement should be avoided.
