Latest Historical geology Stories
A new study looking at past climate change, asks if these changes in the future will be spasmodic and abrupt rather than a more gradual increase in the temperature
UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years
The exceptional preservation and diversity of dinosaur, bird and early mammal fossils present in the fossil beds of northern China are famous. How these creatures died, and why hundreds of creatures from different habitats were buried together on ancient lake floors, has yet to be understood.
The Life, Earth & Health Sciences Magazine EurekaMag.com has published 1,874 new articles on geologic mapping.
Polarstern, a research icebreaker, returned from the South Pacific in 2010 with a scientific treasure. The treasure, described in a recent issue of Science, consisted of ocean sediments from a previously almost unexplored part of the South Polar Sea.
A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals.
An international team of scientists have discovered the first record of dinosaurs from Saudi Arabia.
The temperature of the Earth’s mantle during the Archean eon some four billion years ago was significantly higher than it is today, causing the crust to become unstable and drip back down into the mantle, according to research published this month in Nature Geoscience.
And according to a new study, very little of Earth's temperature variation in the past thousand years has had to do with variations in solar activity.
West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East Antarctica.
The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...
Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
