Earliest Known Scorpion Fossil Discovered In South Africa
2013-09-03 12:41:53

Lee Rannals for redOrbit.com - Your Universe Online Scientists publishing a study in the journal African Invertebrate say they have discovered a 350-million-year-old fossilized scorpion. The specimen, discovered in rocks from the Devonian Witteberg Group near Grahamstown, is a new species of scorpion called Gondwanascorpio emzantsiensis. Dr Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the specimen, which is said to be the oldest known land-living...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder 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. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world. However, new research conducted by the University of Lincoln, the National Museum in Bloemfontein, South Africa, and the University of Bristol suggests that the end can also be the beginning. This research, which was published this month in the Proceedings of the Royal Society B, noted that the ancient closest...

Last Glacial Maximum Peaked In Spain Much Earlier Than Elsewhere
2013-08-26 14:15:13

Brett Smith for redOrbit.com - Your Universe Online 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 published in Scientific Reports suggested that the glacial peak was much earlier in modern-day Spain. According to study researchers, their findings could inform more localized models of glacier activity and be used to calculate the effects of climate change. “We wanted to...

West Antarctica Deglaciation Began Much Earlier Than Thought
2013-08-15 10:21:16

Lawrence LeBlond for redOrbit.com - Your Universe Online 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. Scientists have known for more than a century that ice ages come and go due to the wobbling of the Earth as it orbits the sun. Increases in the intensity of summer sunlight in the Northern Hemisphere melted the ice sheets...

Oceans May Change Drastically In The Future
2013-08-06 05:37:31

April Flowers for redOrbit.com - Your Universe Online A new study, led by Scripps Institution of Oceanography, reveals the look of the oceans will change drastically in the future as the coming greenhouse world alters marine food webs and gives certain species advantages over others, if history's closest analog is any indication. Richard Norris, paleobiologist at Scripps Institution of Oceanography, UC San Diego, worked with an international team of scientists to show the ancient...

Climate Change Affecting Marine Species
2013-08-05 04:54:04

redOrbit Staff & Wire Reports - Your Universe Online Global warming is forcing marine species to alter their breeding times and shift their geographic distribution towards the poles, according to new research published in this month's edition of the journal Nature Climate Change. The study comes from an ongoing research project, in which researchers from 17 international institutions are conducting a three-year global meta-analysis of the impact of climate change on marine systems....

New Dinosaur Triceratops Relative
2013-07-17 14:28:22

Brett Smith for redOrbit.com - Your Universe Online Paleontologist say they have discovered the fossil of a massive new relative of Triceratops in Utah. The 2-ton, 15-foot long Nasutoceratops titusi had the familiar bony frill at the base of its skull, an oversized nose and horns that curved out and forward like a steer's, according to a report in Proceedings of the Royal Society B. Paleontologists who were involved in the discovery said they weren't sure what function the dinosaur's...

Unique Dinosaur Roamed The Desert Of Supercontinent Pangea
2013-06-25 09:03:28

April Flowers for redOrbit.com - Your Universe Online Pangaea, a single supercontinent existing from 300-200 million years ago, 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. A new study, from the Society of Vertebrate Paleontology, supports the idea that Pangaea had an isolated desert at the center of the supercontinent with unique...

Paleontology
2014-01-12 00:00:00

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
2013-04-19 19:33:20

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
2013-04-01 11:05:27

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...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

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...

Geologic Clock With Events And Periods

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...
