How are fossil evidence for Pangea?
WEGNER’S EVIDENCE FOR CONTINENTAL DRIFT Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today’s continents and landmasses to form the supercontinent Pangea. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents.
How were fossils used as evidence?
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth. Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
What is the best evidence for Pangea?
paleomagnetism
Finally, the strongest evidence for the existence of Pangaea is something called paleomagnetism. Some rocks have minerals inside ofthem that are magnetic, and when the rock forms those magnetic minerals will line up and point to the North Pole.
What do fossils and rocks tell us about Pangaea?
What did the fossil evidence show? We know that land herbivores couldn’t fly. And we also know they were incapable of swimming. The reason is that Earth existed as one giant supercontinent Pangaea.
Why are fossils a good source of evidence for evolution?
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
What is an example of fossil evidence?
Some of the types of fossil evidence commonly used by scientists include trace fossils, molds and casts, replacement fossils, petrified fossils, amber and original material fossils. Examples of trace fossils include footprints, burrows and fossilized feces that have been left behind by organisms.
What are the evidence of Pangaea?
Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart.
What does evidence of glaciers tell us about Pangaea?
Evidence of ancient glaciers that existed around 250 million years ago can be found on the landmasses of South America, Antarctica, Africa, India and Australia. 4. Based on the evidence of glacier, it is likely that the landmass of (South) Africa was located over the south pole at the time of Pangaea.
