Feliform evolutionary timeline. All modern carnivorans, including cats, evolved from miacoids, which existed from approximately 66 to 33 million years ago.There were other earlier cat-like species but Proailurus (meaning "before the cat"; also called "Leman's Dawn Cat"), which appeared about 30 million years ago, is generally considered the first "true cat".
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
The evolution of the digestive system has formed a significant influence in mammal evolution. With the emergence of mammals, the digestive system was modified in a variety of ways depending on the animal's diet. For example, cats and most carnivores have simple large intestines, while the horse as a herbivore has a voluminous large intestine. [127]
The ancestors of these modern felines are thought to have evolved just under 10 million years ago. Believed to be larger than the species we recognize today, Europe’s cats would have inhabited ...
A 2006 investigation into cat fossils The wide distribution and wide evolutionary variances between these species have made reasonable taxonomy difficult for researchers.
Pseudaelurus is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago. It is considered to be a paraphyletic grade ancestral to living felines and pantherines as well as the extinct machairodonts (saber-tooths), and is a successor to Proailurus.
Dinofelis is an extinct genus of machairodontine (sabre-toothed cat), usually classified in the tribe Metailurini.It was widespread in Europe, Asia, Africa and North America from 5 million to about 1.2 million years ago (early Pliocene to early Pleistocene).
Ornithischian (bird-hipped) dinosaurs had a pelvis shape similar to that of birds, or avian dinosaurs, which evolved from saurischian (lizard-hipped) dinosaurs. [71] The Heterodontosauridae evolved a tibiotarsus which is also found in modern birds. These groups are not closely related. [72] Ankylosaurs and glyptodont mammals both had spiked ...
