Today’s sloths might be known as slow, small animals, but their ancestors developed large body sizes at an amazing rate, according to an evolutionary reconstruction published September 10 in BMC Evolutionary Biology.
After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared.
Gomphotheres, genetic relatives of the elephant, were thought to have roamed North America and gone extinct long before humans reach the continent. But, according to a new study, researchers have uncovered evidence that North America’s earliest humans may have preyed on the ancient mammals.
The current study used shark teeth collected from a new coastal site on Banks Island, which allowed them to gain a more complete understanding of the changes in ocean water salinity across a broader geographic area.
The Silvacola acares is a tiny hedgehog species that lived roughly 52-million-years ago, during the Eocene Epoch period. Its fossil remains were recently identified by a University of Colorado Boulder-led team working in British Columbia.
Originally thought to be a sequential progression, human evolution has been shown to include a rich tapestry of species that interbred over thousands of years.
In the past, scientists concluded many of man’s defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately.
Most sharks today are strictly saltwater fish, however, a new study led by the University of Colorado Boulder and the University of Chicago reveals that this was not the case 50 million years ago.
The hair-raising stunt kicks off with a new season of River Monsters in Latin America MIAMI, June 30, 2014 /PRNewswire/ -- Monster Week premieres on Discovery en Espanol with
Mapinguari The mapinguari or mapinguary is an ape-like cryptid said to inhabit the Amazon rainforests of Brazil and Bolivia. It is also known as the Isnashi. Several attempts to find physical evidence that the creature exists have been conducted. Samples have been gathered, but when analyzed it was found to be from known animals and some of the castings of tracks were inconclusive. Native folklore has described the creature as having only one eye, long claws, backward feet, a...
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 garhi is a gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw ad Tim White, an American paleontologist. The remains are believed to be a human ancestor species and most likely the direct ancestor to the human genus Homo. Tim White was the scientist to find the first of the key A. garhi fossils in 1996 within the Bouri Formation found in the Middle Awash of Ethiopia’s Afar Depression....
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...
The Neanderthals or Neandertals are an extinct species or subspecies of the genus Homo which is closely related to modern humans. They are known from fossils, dating back from the Pleistocene period, which have been found in Europe and parts of western and central Asia. The species gets its name from Neandertal, “Neander’s Valley”, the location in Germany where it was first uncovered. Neanderthals are classified either as a subspecies of Homo sapiens or as a distinct species of the...
