Do you think that 10'000humans could survive the hell creek formation?
This is assuming that humans are starting from scratch and that we don't have to deal with atmosfera differences. I personally think we are done because of the fact that dakotaraptor, nanotyrranus, and juvenile tyrranosaurus exist these predators were like nothing we've experienced, taller faster and had better speed, smell, hearing, and eyesight to boot. Alot of people think that humans would start to build and craft weapons, shelter, etc but they forget that humans need alot of time to build these predators would see us as easy prey and would likely hunt us to an extreme degree. Hunting would be harder because hell creek was a vast subtropical coast plain meaning that running down prey would be near impossible due to the obstacles in the way also theropods have an extremely efficient respiratory system that is almost as good as ares
