PRESENT DAY
Cretaceous- last period and ending with the extinction of the dinosaurs
In 1920, 1922 and 1929, Wegener published updated editions of The Origin of Continents and Oceans
He also added further evidence he had gathered in Greenland, which showed that Greenland and North America were once linked
Frank Bursley Taylor- An American geologist who had published evidences to support the idea of Continental Drift or Wegener’s theory.
Geological ‘Fit’ Evidence
It is the matching of large-scale geological features on different illustration showing similar rOck assemblages across different continents.
The Appalachian Mountains of eastern North America linked with the Scottish Highlands.
The familiar rock strata of the Karoo system of South Africa matched correctly with the Santo Cataring system in Brazil.
Brazil and Ghana Mountain ranges agreeing over the Atlantic Ocean.
Glaciers carve- rocks and leave marks as they move.
Coal deposits- are found in sedimentary rock basins, where they appear as SUCcessive layers.
Mesosaurus - is known to have been a type of reptile, similar to the modern crocodile, which propelled itself through the water with its long hind legs and limber tail.
Found solely in South Africa and Eastern South America.
Cynognathus - was a mammal-like reptile. Roaming the terrains during the Triassic period (250 to 240 million years ago), it was as large as a modern wolf.
Lystrosaurus - which translates to ‘shovel reptile.’ is thought to have been a herbivore with a stout build like a pig.
Found in Antarctica, India, and South Africa.
Glossopteris - the most important fossil evidence found in the plant (found in Australia, Antarctica, India, South Africa, and South America-all the southern continents.)
Glossopteris seed - is known to be large and bulky and possibly could not have drifted or flown across the oceans to a separate continent.
