What is a glossopeteris?

What evidence of climate change did Alfred Wegener use?

The evidence Alfred Werener had were that they found this play called glossopeteris or something like that in the arctic circle and the plat was a tropical plant so it couldn't have grown in the arctic circle. Also the found the fossils of a animal called messosaurus and it was found on the coast of south America and south Africa and the animal wasn't an salt water reptile, could barely swim and he was cold blooded. Alfred Wegener also noticed that the continents fit like a puzzle but anyway, they found glacial scratches in Africa witch isn't close to the south pole. They also found similer coal fields in north America and Europe. Also the mountain ranges in south America and south Africa matched .
