If you compare historical photos of glaciers with those taken more recently, you can see that where there was formerly ice there is now very often nothing but rock. Geographers, however, are less interested in the area covered by a glacier, and more interested in its mass. Researchers from FAU have now investigated all glacial areas in South America in more detail than ever before.

Coralline red algae have existed for 130 million years. At least this was the established view of palaeontologists all over the world until now. However, this classification will now have to be revised after fossils discovered by researchers at FAU prove that coralline red algae existed as far back as 430 million years ago.
