Thagrastay, really, this idea is all one big assumption, we have nothing to anchor it as a possibility in our current model of history.
I would just like to correct rsl12,
Dinosaurs were most certainly not cold blooded. There is absolutely no way in hell that an animal of that size could sustain it’s metabolism and bodily functions though direct sunlight and/or the local climate. There were also many smaller species appeared to be very fast and agile which would also require allot more energy input then a cold-blooded animal would have. Further more paleontologists now believe that birds are the closest genetic relatives of dinosaurs (terrible lizards), which are warm blooded.
