Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. They are also referred to as the robust australopithecines.
Paranthropus aethiopicus is an extinct species of robust australopithecine from the Late Pliocene to Early Pleistocene of East Africa about 2.7–2.3 million years ago. However, it is much debated whether or not Paranthropus is an invalid grouping and is synonymous with Australopithecus, so the species is also often classified as Australopithecus aethiopicus. [1]
that they went extinct due to natural climate change. Life restoration of Thylacoleo carnifex (also known as the marsupial lion) This theory is based on evidence of megafauna surviving until 40,000 years ago, a full 30,000 years after homo sapiens first landed in Australia, and thus that the two groups coexisted for a long time.
It was long assumed that if Paranthropus is a valid genus then P. robustus was the ancestor of P. boisei, but in 1985, anthropologists Alan Walker and Richard Leakey found that the 2.5-million-year-old East African skull KNM WT 17000—which they assigned to a new species A. aethiopicus|A. aethiopicus—was ancestral to A. boisei (they ...
Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.5 to 1.15 million years ago. [1] The holotype specimen , OH 5 , was discovered by palaeoanthropologist Mary Leakey in 1959 at Olduvai Gorge, Tanzania and described by her husband Louis a month later.
It’s no fish tale. Giant goldfish have been appearing in freshwater lakes around the country. It’s a development that has surprised people.
This crustal boundary is the Great Lakes tectonic zone (GLTZ). It is a 1,400 km (870 mi) long paleo suture that separates the more than 3,000-million-year-old Archean gneissic terrane to the south – Minnesota River Valley subprovince – from the 2,700-million-year-old Late Archean greenstone- granite terrane to the north – Wawa Subprovince ...
A native Great Lakes whitefish thought extinct for nearly 40 years has been rediscovered by scientists – in the wrong ... "The Great Lakes will never go back to what they were 200 years ago," he ...
