By Rick Steelhammer What's 12 feet long, has 6-inch claws and weighs a ton or more? It's Megalonyx jeffersonii, and starting Saturday, a precise scientific replica of its skeletal remains will be on display at the West Virginia Geological Survey Museum near Morgantown.
Researchers in the US and UK have concluded that tools developed by Homo sapiens were no more sophisticated than those used by the Neanderthals.
Tiny marks on the teeth of an ancient human ancestor known as the "Nutcracker Man" may upset current evolutionary understanding of early hominid diet.
Leaping, furry mini-monkeys that were as small as mice crossed the Bering land bridge long before humans, representing North America's oldest known primates.
The oldest fossils to date of early rabbit relatives were recently unearthed. These specimens, which are 53 million years old, are tiny ankle bones which are clearly adapted to running.
Scientists, wringing their hands over the identity of the famed "hobbit" fossil, have found a new clue in the wrist. A study of the bones in the creature's left wrist lends weight to the human ancestor theory, according to a report in Friday's issue of the journal Science.
By Prendergast, Kate Our prehistoric ancestors survived rapid climate change and rising temperatures as extreme as those we face today, says Kate Prendergast.
By LOS ANGELES TIMES A 11/2-million-year-old skull and an equally old jaw found in Kenya are helping rewrite the history of early man, eliminating one reputed ancestor from the human lineage and suggesting that another was much more primitive than previously believed, researchers said.
An international research team has found evidence that some of the earliest members of our species had evolved our characteristically long developmental period, and most likely our extended childhood, over 160,000 years ago.
In a discovery sure to fuel an old debate about our evolutionary history, scientists have found a remarkably complete skeleton of a 3-year-old female from the ape-man species represented by "Lucy."
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...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
