final assembly of Pangea) to find relationships between LIP event attributes (e.g., igneous volume, extent, distance from pre-existing continental margin) and ocean basin attributes (e.g., length of new ocean basin/rifted margin) and how these varied during the progressive break up of Pangea...
After all, human beings evolved only a few hundred thousand years ago, so no one was around to witness this geomorphological monstrosity. How did scientists “discover” Pangea and other supercontinents of the past? Nowadays, they can study the geologic record and use radioactive dating, seismic...
But one continent to rule them all couldn't last, and sometime between 280 and 200 million years ago, Pangea started disintegrating as magma began pushing up from beneath the mega-supercontinent, creating rifts in the land that would later become sea floor. As Pangea cracked, the top part ...
Also notable is thatPangea existed as one supercontinentin this era. Dinosaurs lived on one supercontinent. Plate tectonics was the mechanism that eventually tore continents apart. Don’t forget that dinosaurs existed for 160 million years. Socontinental driftgradually rifted dinosaurs apart. We know ...
The super-continent Pangea during the Permian period (300 – 250 million years ago). Credit: NAU Geology/Ron Blakey The continents migrated across the surface, occasionally combining to form a supercontinent. Roughly 750 million years ago, the earliest-known supercontinent called Rodinia began to b...
