@ariaflame Near its present location.
"About 100 million years ago, Alaska’s location on the globe wasn’t much different than it is now, but it was considerably warmer—similar to today’s climate in Portland, Oregon, or Seattle, thousands of miles south.#
@Nonog was Alaska ever warm? Have you been there in summer? What makes anyone think dinosaurs didn’t migrate seasonally?
@Catawu I've been there in the summer and the winter. I don't think migration would have helped them if it was as cold as it gets now. Article says it was about like Portland. Tolerable for dinosaurs.
@Nonog Yeah, but weather reports from back in the day were kinda Stone Age. (Ok, snark). I think the planet has gone through enough shifts & rifts that the North Pole was probably the Mediterranean and the South Pole was probably a vacation spot. I’m not surprised to find Dino feet anywhere.
@Nonog Where was Alaska in the time of the dinosaurs? I know Antarctica was at a latitude nearer the equator. Tectonic plates shift
