Those are the very first words of the article. Modern sea turtles separated from other lines of turtles about 110 million years ago. It has been much warmer at times in the past 110 million years than it is now, yet turtles survive.
AP, Fox, and all the major news organizations are running this crap story today.
Also, there weren’t any U.S. beaches millions of years ago. Not even a thousand years ago. Careless writing.
