How does 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 the present-day climate could not have supported the organisms that made the fossils.
• Similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.
