Look, I'm not a geologist. But every reconstruction I've seen has Antartica at the pole during this time. Even when it was smashed together with other continents it was still in the extreme south.
If there's a reconstruction that says different, please point me to it, because I use this argument a lot.
“Antarctica has sat at much the same latitude for the last hundred million years. But during the Cretaceous it enjoyed a warmer, lusher climate, similar to that of the U.S. Pacific Northwest today. (The Cretaceous period started 144 million years ago and ended 65 million years ago.)”
I guess I'm thinking of earlier years. Yes - your observations make sense to most of us that realize that the earth has been changing for a long, long time.
(Although didn't the Model T come out in the late Cretaceous, and is believed to have killed all the dinosaurs?)
