The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought.
By Shen, Shu-Zhong Zhang, Yi-Chun ABSTRACT- The uppermost 5-15 m of the Douling Formation in the southern Hunan area. South China, yields a diverse fauna comprised of ammonoids, bivalves, and brachiopods.

A study published in the current issue of Science challenges the long-held belief that diversity of marine species has been increasing continuously since the origin of animals.
A recent study has shown that tiny slivers of diamond forged on an infant Earth may contain the earliest traces of life, 500 million years earlier than previously believed.
In a paper published in this monthâ€™s â€˜Geophysical Journal Internationalâ€™, Dr Graeme Eagles from the Earth Sciences Department at Royal Holloway, University of London, reveals how one of the largest continents ever to exist met its demise.
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...
