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]
The fossil examined in the study, collected during a 2011 expedition by the Antarctic Peninsula Paleontology Project, was found encased in rock that dated back 68.4 to 69.2 million years and ...
The world’s oldest known fossilized skin belonged to a species of reptile that lived before dinosaurs roamed the Earth, a new study has found. Rare skin fossil is oldest by 130 million years ...
Restoration. Like the modern cheetah, Acinonyx pardinensis is generally thought to have been adapted to running down prey. It probably took larger prey than living cheetahs, with estimated prey masses of 50–100 kilograms (110–220 lb), [2] though the idea that its ecology was similar to a modern cheetah has been contested by some authors, who suggest an ecology more similar to pantherine ...
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to ... less than 270 million years old, but the recent fossil find is thought to be an ...
A living fossil is a deprecated term for an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be.
