Wegener used similar fossils in Africa and South America as part of the argument for his theory of continental drift - that the continents were connected millions of years ago but then moved apart. He thought that all the continents were connected at one time and they shared the same plat and animal life. Some of the fossils were of species that grew in only one type of climate yet the fossils were found on continents with differing climates.
How did Wegener explain the fossils of plants and animals found on different continents. Since neither reptile could have swum great distances across salt water he inferred that they once lived on a single landmass that has since split apart. Its showing the evidence that Wegener make use of continental drift.
