So what are your thoughts on the Spinosaurus - Tyrannosaurus swap scenario? I know you are probably busy with this blog and your other ones, but if you do have the time to respond, I thank you in advance. After all, Hell Creek and the Kem Kem Beds are not suitable to the large carnivores from the opposite habitats. Peace out.
You are entirely right, these theropods would have a very hard time surviving in the other’s environment.
Our thoughts would be to also consider weather and deseases. These animals wouldn’t be prepared to deal with illnesses of both a different continent, time, and climate. This last thing also plays a major role since heat and humidity was vastly different between the two environments.
We’d also note that Kem Kem beds thus far yield a pretty crazy diversity of theropods all competing for food, since the switched species would deal with a totally different niche, even Tyrannosaurus would have a hard time outcompeting all the animals already compeltely adapted to their environment, no matter how stronger its bite-force or sense are.
All in all we still think both species would not live long enough to see the next generation.
