By

examining the location utilizing Google Earth, the scientists discovered
that there were around a hundred

or two of these drumlins and whalebacks sprayed around the
location of Twyfelfontein in Namibia

These drumlins were crafted by ice streams that streamed over the location around300 million years back. In between from time to time, numerous countless rocks covered the structures– and after that ultimately worn down once again, re-exposing them.

Likewise, megawhalebacks are hills worn down by ice streams, however when seen from above, they are longer and more elliptical fit than drumlins.(************* ).

By taking a look at the place and orientation of these megawhalebacks, the group concluded that the ice stream most likely streamed towards the northwest into shallow waters in modern-day Brazil. Their findings even more verify that southern Africa was accompanied South America and sat over the South Pole throughout this late Paleozoic age.(************* ).(********** ).
