New Saber-Toothed Cat Discovery Sheds Light On Interactions Between Early Humans And Predators
2014-04-02 08:15:46

April Flowers for redOrbit.com - Your Universe Online At the Schöningen open-cast coal mine in north-central Germany, near Hannover, researchers from the Lower Saxony Heritage Authority and the University of Tübingen have discovered the remains of a saber-toothed cat. The remains were preserved in rock strata some 300,000 years old, placing them during the Paleolithic Era. The Schöningen mine is famous for the discovery of three wooden spears, unearthed in 1997 by Hartmut Thieme of...

Fossil Skeleton Of Australopithecus Is Older Than Previously Believed
2014-03-17 04:51:40

April Flowers for redOrbit.com - Your Universe Online Thirteen years of meticulous excavation by South African and French scientists has shown that the nearly complete fossil skeleton of Australopithecus, nicknamed Little Foot, is most likely around 3 million years old. Professor Ron Clark from the University of Witwatersrand led the study, which refutes previous dating claims that suggest Little Foot is younger. The findings, published in a recent issue of the Journal of Human...

Ancient Sloths Went Swimming
2014-03-13 05:04:02

Lee Rannals for redOrbit.com - Your Universe Online Scientists at the National Museum of Natural History in Paris say ancient sloths once spent some of their time in the ocean. Sloths are known as tree dwellers, but the latest research published in the Proceedings of the Royal Society B says that these creatures use to head out into the sea about five to eight million years ago. The team came to this conclusion after analyzing Peruvian sloth fossils belonging to five different...

A failed Saharan Atlantic Ocean rift zone Break-up of the supercontinent Gondwana about 130 Million years ago could have lead to a completely different shape of the African and South American continent with an ocean south of today's Sahara desert, as geoscientists from the University of Sydney and the GFZ German Research Centre for Geosciences have shown through the use of sophisticated plate tectonic and three-dimensional numerical modelling. The study highlights the importance of rift...

Permian Mass Extinction May Have Happened In The Blink Of An Eye
2014-02-11 05:07:01

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, the largest mass extinction event in the history of animal life on Earth occurred — wiping out more than 96 percent of marine species and 70 percent of terrestrial species. This included the largest insects known to have inhabited the planet. Scientists have explored many theories to explain the cause of the end-Permian extinction, as it came to be known. Those theories include an asteroid...

A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists have discovered. Denver, Colorado (PRWEB) December 06, 2013 A human ancestor characterized by "robust" jaw and skull bones was a muscular creature with a gorilla-like upper body and more adaptive to its environment than previously thought, scientists have discovered.

Minerals Were Scarce When Life First Formed On Earth: Study
2013-11-26 08:05:20

redOrbit Staff & Wire Reports - Your Universe Online Just eight percent of the nearly 5,000 different types of minerals currently found on Earth were present on or near the planet’s surface when life first originated, according to new research published in the latest edition of the American Journal of Science. According to researchers from the Carnegie Institution for Science, life came about as a result of natural processes that took advantage of raw materials available during...

Extinction Event During End Of The Permian Period Likely Due To Acid Rain
2013-11-23 05:08:21

April Flowers for redOrbit.com - Your Universe Online At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history. Previous research has suggested that contemporaneous volcanic eruptions in Siberia might have triggered this extinction. A new study, published in the journal Geology, reveals that the atmospheric effects of these eruptions could have been...

Signs Of Ancient Bacterial Ecosystems Found In Australia
2013-11-13 05:44:54

April Flowers for redOrbit.com - Your Universe Online Scientists trying to reconstruct the rise of life during the period of Earth's history when it first evolved find the task daunting because the planet's oldest sedimentary rocks are not only rare, but nearly always altered by hydrothermal and tectonic activity. A new study, published in the journal Astrobiology, reveals the well-preserved remnants of a complex ecosystem in a nearly 3.5 billion-year-old sedimentary rock sequence in...

Palaeovespa
2014-04-18 16:08:43

Palaeovespa is a genus of wasps that holds seven species, all of which are extinct. Two of the species were discovered in Baltic amber deposits from Europe dating back to the middle Eocene era, while the other five were found in Florissant Formation amber from the Priabonian stage era in Colorado in the United States. This genus, and four of its species, was first described in 1906 by Dr. Theodore Cockerell in the Bulletin of the Museum of Comparative Zoology. Cockerell described all but one...

Australopithecus africanus
2013-11-29 10:55:07

Australopithecus africanus was an early hominid, an australopithecine that lived between roughly 3.03 and 2.04 million years ago in the later Pliocene and early Pleistocene. Au. africanus was of slender build and was thought to have been a direct ancestor of modern humans. Fossil remains signify that Au. africanus was considerably more like modern humans that Au. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. This hominid has only been...

Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...

Geologic Clock With Events And Periods

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...

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...
