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 ...
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 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]
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 ...

All of these were described from fossils before later being found alive. [15] [16] [17] The fact that a living fossil is a surviving representative of an archaic lineage does not imply that it must retain all the "primitive" features (plesiomorphies) of its ancestral lineage. Although it is common to say that living fossils exhibit ...
Researchers uncovered “remarkably complete” fossils from the skull and jaws of the mammal in rocks that date back to the period just after the extinction of the dinosaurs in the Corral Bluffs ...
