How did fossil evidence support Wegener's hypothesis of continental drift?

• Similar fossils are found along continental margins that appear to join together.

• Fossils are found in areas where present-day climate could not have supported the organisms that made the fossils.

• Similar fossils of land-dwelling dinosaurs are found on continents separated by oceans.

• All of the above.
