Reconstruction of "Acinonyx kurteni""Acinonyx kurteni", or the Linxia cheetah, is a discredited fossil specimen of an extinct cheetah discovered in China.The scientific name was assigned for the skull that was originally described to be that of an extinct species of cheetah, endemic to Asia during the Late Pliocene sub-epoch.
Miracinonyx (colloquially known as the "American cheetah") is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus), although its apparent similar ecological niches have been considered questionable due to anatomical ...
The oldest cheetah fossils, excavated in eastern and southern Africa, date to 3.5–3 mya; the earliest known specimen from South Africa is from the lowermost deposits of the Silberberg Grotto (Sterkfontein). [2] [8] Though incomplete, these fossils indicate forms larger but less cursorial than the modern cheetah. [31]
Many people alive today carry traces of Denisovan DNA, but — because fossils of these extinct ancestors are still few and far between — experts in human origins still don’t know exactly what ...
A 68-million-year-old skull fossil found in Antarctica has revealed the oldest known modern bird, which was likely related to the waterfowl that live by lakes and oceans today, according to new ...
From the early Pleistocene, the earliest African cheetah fossils have been found in the lower beds of the Olduvai Gorge site in northern Tanzania, although cheetah fossils in Southern Africa were found to be 3.5 to 3.0 million years old. The Southeast African cheetah is the second-oldest subspecies. [11]
Its production was depicted on wall murals in ancient Egyptian tombs in 2000 BC, and traces of the practice in Europe date back almost 7,000 years, but scientists say the Tarim Basin samples are ...
The earliest direct evidence of life are stromatolites found in 3.48 billion-year-old chert in the Dresser formation of the Pilbara Craton in Western Australia. [4] Several features in these fossils are difficult to explain with abiotic processes, for example, the thickening of laminae over flexure crests that is expected from more sunlight. [57]
