I need to know what the fossil evidence, evidence from mountain ranges across continents, evidence from measurements of plate movement, and evidence from rock layer sequence of continental drift.
I am doing this for a Biology project and I would appreciate some help.

Thanks

Eduard Suess was an Austrian geologist who first realized that there had once been a land bridge connecting South America, Africa, India, Australia, and Antarctica. He named this large land mass Gondwanaland (named after a district in India where the fossil plant Glossopteris was found). This was the southern supercontinent formed after Pangaea broke up during the Jurassic period. Suess based his deductions on the fossil plant Glossopteris, which is found throughout India, South America, southern Africa, Australia, and Antarctica.
Fossils of Mesosaurus (one of the first marine reptiles, even older than the dinosaurs) were found in both South America and South Africa. These finds, plus the study of sedimentation and the fossil plant Glossopteris in these southern continents led Alexander duToit, a South African scientist, to bolster the idea of the past existence of a supercontinent in the southern hemisphere, Eduard Suess's Gondwanaland. This lent further support to A. Wegener's Continental Drift Theory

Rock samples from Africa and South America were found to be the same, The Mid Atlantic Ridge was caused by the movement of the earths plates away from eachother,
God I did this last year for Leaving Cert Geography and now I can barely remember!
