The American “cheetah” wasn’t a cheetah at all

Paleontology News

Recent research into the extinct 'American cheetah' (Miracinonyx) has clarified that despite its historical classification and physical appearance, the animal was not closely related to the modern African cheetah. Instead, new evidence confirms it was a distinct branch of the puma lineage. By analyzing fossils from the Yukon, researchers have uncovered an unexpectedly flexible dietary range. While southern populations primarily hunted terrestrial prey similar to modern mountain lions, northern populations living in the Yukon adapted to their environment by incorporating fish into their diet, potentially including salmon. This revelation highlights the incredible behavioral plasticity of prehistoric felids and forces a re-evaluation of how these predators occupied North American ecosystems during the Pleistocene.
