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".
2.5 Ma Earliest species of Arctodus and Smilodon evolve. 2 Ma First members of genus Homo, Homo Habilis, appear in the fossil record. Diversification of conifers in high latitudes. The eventual ancestor of cattle, aurochs (Bos primigenus), evolves in India. 1.7 Ma Australopithecines go extinct. 1.2 Ma Evolution of Homo antecessor.
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.
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 ...
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]
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in every continent except for Australia and Antarctica. The earliest species is known from the Middle Miocene, while the latest species Smilodon populator survived up to the Early Holocene (8,200~9,100 years ago).
Dinosaurs evolved from more primitive reptiles in the aftermath of Earth's biggest mass-extinction event caused by extreme volcanism at the end of the Permian Period about 252 million years ago.
The Oligocene featured the expansion of grasslands which had led to many new species to evolve, including the first elephants, cats, dogs, marsupials and many other species still prevalent today. Many other species of plants evolved in this period too. A cooling period featuring seasonal rains was still in effect.
