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.
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 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]
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 ...
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.
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 ...
The oldest known person alive today is Inah Canabarro Lucas, a Brazilian woman, at 116 years, 250 days (born 8 June 1908). These are single examples; for a broader view, see life expectancy (includes humans).
