Reptile = cold blooded, ie, can’t live in a cold climate.
Global warming or cooling?
Evidence abounds that these animals lit all their Menorah candles and ate too much starchy beans which added to their flatulence!!!
AKA the flora fossils show a tropical setting during the time these animals roamed the wild. So the shift of the axis and plate techtonics are considerd the main factor in the remains being where they wwere found!!!
T. Rex was warm blooded.
There is some evidence that loggerhead turtles can thermoregulate. Large tuna also.
When I first arrived in Alaska, while in the USAF, I was warned to stay away from snow snakes. When I asked why they were so dangerous I was told that they would “crawl up your ass and freeze you to death”. Ever since that day I have stopped heeding any warnings in life.
Dinosaurs may have been warm blooded, via the same double circulatory pathways used by mammals and birds. Plesiosaurs aren’t dinosaurs, but they may have had other methods of warm-bloodedness. Several species of “cold-blooded” animals keep their blood warm:
* Perpetual motion (sharks)
* Ducti Mirabilli (sp?) (super-efficient blood filtering) (tuna)
[don’t complain to me about biology puns]
* Partial division of hearts (crocodilians)
* Massive size (dinosaurs?)
