It was very cold outside (tiny snowflakes falling) which seems to be the situation all over in the southwest right now as some cold air mass has moved down from the north. This made me think of the time of dinosaurs, the weather then wasn't all so peachy all the time. No doubt freak cold air masses were forced down into their habitat by the jet stream occasionally.
The colors and patterns are all speculation by the scientists and artists.
No one really knows.
All my life, given the choice to go back to any period of time, I would choose the time of dinosaurs.
I think it would be fascinating to see them in real life,
ah but I would probably end up being a tasty little morsel for somebody.
Not a dinosaur but for as cold as it was this woolly mammoth is well suited for it.
And I leave you with utterly embarrassing monstrosity that greets you upon entering
Vernal, Utah. Boy, if I lived here I'd start up a petition to have that thing replaced.
