Latest Historical geology Stories
Paleontologists working in China recently unearthed what could be the earliest collection of fossilized dinosaur embryos to date.
Researchers say that there was an abrupt and widespread climate change that took place in the Sahara Desert 5,000 years ago.
Earth's tropical climate history has been revealed in unprecedented detail – year by year, for almost 1,800 years – by two annually dated ice cores drawn from the tropical Peruvian Andes.
Temperature patterns during Earth’s last prolonged global “hot spell” some 5.3 million to 2.6 million years ago differed markedly from those of modern times, suggesting current climate models may need to be adjusted to improve future predictions.
Researchers claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet’s species.
According to Jason Moore from Dartmouth College, who presented a study at the 44th Lunar and Planetary Science Conference, evidence from the Chicxulub crater suggests there are possibilities beyond an asteroid impact.
A team of American scientists believe they have solved a geological mystery buried about 100 miles below California.
Deforestation is less likely to occur in areas of the Amazon rainforest that have been placed under strict protection than those that allow for controlled resource extraction.
In the next few centuries, Canada's Arctic Archipelago glaciers will melt faster than ever, according to a new study. Research has revealed that 20 percent of the Canadian Arctic glaciers may have disappeared by the end of our current century, leading to an additional sea level rise of 1.4 inches.
A new study focusing on the mineral molybdenite could provide new insight into the way that various geological and biological processes have resulted in changes to the Earth’s chemistry over the years.
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...
