Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time.
Scientists have debated how nothosaurs swam for a long time. One theory is the reptiles used their paddle-like feet to row with a back-and-forth motion. A second theory has the dinosaurs sweeping their forepaddles in a figure-eight motion
A new study has identified a three- to five-million-year-old Tibetan fox from the Himalayan Mountains that is a possible ancestor to the Arctic fox living today.
Forests affected by fires 66 million years ago during the last days of the dinosaurs recovered no differently than they do today, according to a team of researchers from McGill University and the Royal Saskatchewan Museum.
A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets.
A piece of Eocene Baltic Amber of about 45 million years age contains a well preserved extinct flat bug, which turned out to be a new species to science.
The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature.
The introduction of X-ray tomography has revolutionized the way that fossils are studied, allowing them to be virtually extracted from the rock in a fraction of the time necessary to prepare specimens by hand and without the risk of damaging the fossil.
Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time.
While dinosaurs may have disappeared from the face of the Earth, their lineage has survived in the form of birds and new research has found that both dinosaurs and birds evolved into smaller and smaller sizes – potentially contributing to their success.
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...
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
