Latest Geologic time scale Stories
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.
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.
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.
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.
A research team from MIT has determined that the end-Permian extinction took place over 60,000 years — give or take 48,000 years. From a geologic perspective, that's nearly instantaneous.
The Life, Earth & Health Sciences Magazine EurekaMag.com has published 1,874 new articles on geologic mapping.
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
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 appearing in the latest edition of the American Journal of Science.
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.
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 Australia.
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 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...
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...
