Latest Supercontinents Stories
In devising his theories about evolution, Darwin theorized that species evolved on Earth slowly over millions of years. However, the fossil record doesn’t agree with the slow-and-steady model as a massive explosion of species took place 530 million years ago during the Cambrian era.
European & Eurasian oilfield equipment rental market report is segmented on the basis of geographies, types, and equipment.
Break-up of the supercontinent Gondwana about 130 Million years ago could have lead to a completely different shape of the African and South American continent with an ocean south of today's Sahara desert, as geoscientists from the University of Sydney and the GFZ German Research Centre for Geosciences have shown through the use of sophisticated plate tectonic and three-dimensional numerical modelling.
After the ancestors of modern day Native Americans left Asia, they spent approximately 10,000 years living in the shrubby lowlands of the Bering land bridge, according to genetic and environmental evidence.
Scientists say they have discovered a 350-million-year-old scorpion fossil, recovered from Devonian formation layers in Grahamstown, South Africa.
Pangea, a single supercontinent, dominated the Earth during the Permian era with animal and plant life dispersed broadly across the land. This disbursement is documented by identical fossil species found on multiple modern continents.
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...
