The preponderance of physical evidence supports the concept that all the continents were once united in a single land mass. This makes Pangaea more of a fact than a belief.
Fossil forms in a rock and dirt covers it by digging through.
Pangaea probably?
Scientists are not so sure because during the time of the dinosaurs, which lasted millions of years, continental drift has caused the super continent, Pangaea, to move into different landforms
Plate tectonics and Pangaea you get evidence from ancient climate zones, land features, and fossils
Plate tectonics led to the theory of Pangaea.

Plate tectonics led to the theory of Pangaea.
There definitively was a Pangaea. Pangaea implies one continent. Back when the earth was forming, there was no oceans, thus the whole earth would be referred to as Pangaea. Today continents would refer to how much land is above the ocean.
Because the earth was thought to be made by god, and it was perfect and no continental crusts. The existence of continental crusts is one of the many evidence that proved Pangaea to be a theory. Also, the existence of the fossil records of the same species along the coastlines of 2 different places confirms Pangea. The current movements in earth's crust also provide evidence that Pangaea could have formed. Most scientists were not given this data and therefore the evidence for Pangaea was vague. Only now has the evidence shown more consistency. Science is skeptical my friend.

When Pangaea was in existence, the main animals were reptiles and amphibians. During this time, birds developed also.
The continents appear to have once fit together (like South America and Africa). Also, there were similar fossils found on different continents.
who
the continents fit the locations on the mountain ranges the congruent types of rocks and the same fossil exists on different continents. Hope this helped. :)
Evidence #1: glaciers from the ice ages left striations in the substrate of southern South America, southern Africa, southern India, Antarctica, and southern Australia when they melted and these places are now extremely far apart and most of these continents found with the striations are not found in polar regions. Where the striations occur from the melted glaciers fits with the theory of continental drift and how Pangaea used to exist.Evidence #2: other evidence Wegener had to support his theory of the existence of Pangaea was the distribution of climate belts. He studied sedimentary rock from different regions that were formed during the Paleozoic Era in order to determine a rough estimation of what latitude and longitude the present day continents were. He was able to determine that their were longitudinal climate belts during the Paleozoic Era where coal, desert, reefs, salt deposits, glaciers, and tropics aligned. Ex) He found that southern Europe and the southern part of North America used to be topical areas.Evidence #3: the distribution of similar fossils around the world provides evidence for the previous existence of Pangaea. The only way to explain how fossils of the same animals being found on multiple continents today that existed during the Paleozoic and Mesozoic Era is through the once existing super continent. It is the only way to explain how so many fossils of land animals ended up on multiple continents.
There are no commonly accepted opposing scientific views on plate tectonics or the existence of the supercontinent Pangaea.
