From November 2016 to January 2017 (in other words, summer in Antarctica) Erik Gulbranson and John Isbell found 13 fossil fragments from trees dating back more than 260 million years.

All of this was, however, before history’s greatest mass extinction event. You can read more at National Geographic.
