Latest Historical geology Stories
While we grapple with the impact of climate change, archaeologists suggest we spare a thought for Aboriginal Australians who had to cope with the last ice age.
Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates.
Ancient relatives of crocodiles had a wide range of habitats and ecosystems, with some species built like domestic dogs and others built for swimming through the open seas.
Scientists say they have discovered a 350-million-year-old scorpion fossil, recovered from Devonian formation layers in Grahamstown, South Africa.
Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.
Mass extinction certainly sounds like it would be the end of the line, and perhaps even evoke images of the end of the world. However, new research suggests that the end can also be the beginning.
While it’s widely believed that the world’s massive ice sheets were at their greatest extent 20,000 years ago during the last glacial maximum, new research in Scientific Reports suggested that the glacial peak was much earlier in modern-day Spain.
One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages.
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...
- A small wooded valley; a dell.
- The protecting weather-shed built around the entrance to a house.
- The roofed-over space between the kitchen and the sleeping-quarters in a logging-camp, commonly used as a storeroom.
