More than 200 million years ago, mammals and reptiles lived in their own separate worlds on the supercontinent Pangaea, despite little geographical incentive to do so.
The Gondwana supercontinent underwent a 60-degree rotation across Earthâ€™s surface during the Early Cambrian period.
A team of scientists discovered that blindsnakes are one of the few groups of organisms that inhabited Madagascar when it broke from India about 100 million years ago and are still living today.
Geochemical analysis of rare ancient soil produces new paleoclimate data.
Princeton University scientists have shown that, in ancient times, the Earth's magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate.
Two giant plumes of hot rock deep within the earth are linked to the plate motions that shape the continents, researchers have found.
North America is a continent completely within the Northern Hemisphere and almost completely within the Western Hemisphere. It’s also considered a northern subcontinent of the Americas. It’s bordered to the north by the Arctic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea, and to the east by the Atlantic Ocean. This continent covers an area of approximately 9,540,000 sq miles, about 4.8 percent of the plants surface or about...
The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
The Archean (formerly Archaeozoic) is a geologic eon between the Hadean and Proterozoic eons. The Archean Eon begins at roughly 3.8 billion years ago (Ga) and ends at about 2.5 Ga. But unlike all other geological ages, which are based on stratigraphy, The Archean eon is defined chronometrically. The lower boundary of 3.8 Ga has also not been officially recognized by the International Commission on Stratigraphy. The name Archean is derived from the ancient Greek (Arkhe), meaning...
