	Felidae - Encyclopedia, History, Geography and Biography
		Better known is Proailurus, which lived in the Oligocene and Miocene eras.
		Pseudaelurus is believed to be the latest common ancestor of the three above-mentioned subfamilies and another subfamily, the Machairodontinae.
		This group, better known as the sabertooth cats, became extinct in the Late Pleistocene era.

	Pseudaelurus - Wikipedia, the free encyclopedia
		Pseudaelurus is a prehistoric cat that lived in Europe and North America approximately 20-10 million years ago.
		Pseudaelurus was approximately the size of a cougar by the time it died out.

	Proailurus Information
		One of the next known cats on the feline family tree is Pseudaelurus, which lived 20-10 million years ago.
		Pseudaelurus is also an ancestor of domestic and big cats.
		Other branches of the feline family tree originating with Proailurus gave rise to Dinofelis and Machairodus.

	The origin of the tiger. (Site not responding. Last check: 2007-09-17)
		It was a medium-sized cat that hunted using an ambush technique.
		Pseudaelurus left a legacy in the form of the ocelot, kodkod, margay, tiger cat, pampas cat and Geoffroy's cat.
		It is likely the ancestors of these animals crossed the Bering landbridge somewhere around five million years ago and then gradually made their way to South America.

	BigCats.com Survey : Do you accept the theory that all cat species evolved through adaptation from a single cat species?
		Based on the fossil evidence currently available, the most widely accepted scientific theory on cat evolution is that Proailurus is the ancestor for all cats, those living and those extinct.
		After Pseudaelurus, the fossil record shows a split between the features of saber-toothed cats and conical-toothed cats.
		Proailurus and Pseudaelurus may not have been the only cats from those time perioed, but they are the only fossils that we have.

		Pseudaelurus lorteti was about the size of a large lynx while P validus was the size of a large lynx or small puma.
		The common ancestor of the Nimravidae and the Felidae was the Viverravidae (feline-like) group of miacids some 55 million years ago in the late Eocene.
		Proailurus, a descendent of the miacids, evolved into Pseudaelurus, which split into two main groups, one of which became the modern cats (Neofelids), and one became the Machairodonts (true sabre-toothed cats, a sub-family of the Felidae).

		Pseudaelurus is a felid taxon that has been reported from the early Miocene of Europe, Asia and North America.
		Only three skulls of Pseudaelurus have been mentioned in the literature, all from North America, and none have been associated with postcranial material.
		I review the fossil felid literature, examine type Pseudaelurus specimens, and introduce a generic diagnosis for the genus Pseudaelurus.

	[No title]
		Though Nimverids had a body structure nearly identical to modern cats, the structure of their ear bones seperates them from true cats and places Nimverids in a closely related family of their own (though one small group of scientist thought Nimverids were more closely related to dogs than cats, which I belive is crap).
		By 15 million years ago, Pseudaelurus enterd North America and started radiating into many different species of Pseudaelurus of many different sizes; from house cat size, to near leopard size.
		During the 15 millon year mark (mid-Miocene) in North America, much of the predator niches were filled by memebers of the dog family and a group of carnivores commonly called "bear-dogs" that were left vacant by the Nimverids at the end of the Oligocene.

		The very advanced aspect of the Merychippus in the Trail Creek fauna is the principal criterion for dating the deposit as Barstovian but this assignment is supported by the presence of merycodont horncores of the Meryceros type.
		The carnivores, herein referred to Tomarctus rurestris and Pseudaelurus intrepidus, also suggest (but do not prove) late Miocene age in that the holotypes of both species are Barstovian.
		The value of species within these genera of carnivores for distinguishing Barstovian from Clarendonian rocks is not known because most are represented by inadequate series of specimens.

		Hecht (in Chaline, 1983) describes polar bear evolution; the first "polar bear" subspecies, Ursus maritimus tyrannus, was a essentially a brown bear subspecies, with brown bear dimensions and brown bear teeth.

	Lions and Big Cats - Sabre-Toothed Cats
		One variety of Nimravid, Barbourofelis fricki (15-7 Ma), was a lion-sized 'cat' which had the most highly developed canines of all the sabre-toothed species.
		The earliest true cats arose some 30 Ma (Proailurus, living in Europe), and in the Americas the oldest fossil dates from 16 Ma (Pseudaelurus).
		From Pseudaelurus (16 Ma), considered the first of the 'true' cats arose two lineages, one giving rise to all the extant cats (subfamily Felinae), and the other a number of now-extinct cats such as Dinofelis and a group of genera which have been classified as subfamily Machairodontinae, the Sabre-toothed cats.

		Crown felids can be broken up into two subfamilies: 1) the Machairodontinae, the saber-toothed cats (Figure 1, right) and 2) the Felinae or conical-toothed cats, which includes all of the extant members of the family, their immediate ancestors, and close sister taxa.

	Kent Big Cat Research © Neil Arnold 2002 (Layout by Sean Tudor)
		Evolution progressed from the Aeluroidea carnivores which included the Nimravidae paleofelids, which evolved on a parallel with the neofelids.
		Cougar-sized Pseudaelurus are believed to be the ancient ancestors to the modern cats as well as the sabre-toothed felines which first appeared around fifteen-million years ago in the form of lion-sized cats, and up until the Pleistocene era with the Smilodons.
		Fossil remains have never been found outside the New World and date back no further than two-and a half million years ago, and it seems that these cats with eleven-inch long teeth existed as scavengers, and also preyed on slow moving herbivores.

		It is now thought that because cats have always roamed, and that, in prehistoric times, it was possible to cross land bridges to roam all the continents freely, which is difficult for us to imagine today.
		, the lynx-like Ur-Cats, (Pseudaelurus), probably lived in forests, and are assumed to have hunted large rodents and ground nesting birds.
		When the pressures of different habitats created changes in the Ur-Cat's bodies, the ocelots branched from the parent stem in South America about ten million years ago, and along with other little spotted mouse-catchers of the New World jungles, became known as the ocelot lineage.

		If the divergence of these species goes back that far, wouldn't they be more different?
		About 10 million years ago, Pumas branched off from the parent stem of Ur-Cats [Pseudaelurus], which appeared in the Miocene period, and from which directly evolved the species felis, which includes the small wild cats.
		And yet, the pumas, while separate from, say, panthera which includes jaguars and lions, and which branched off about 5 million years ago, it is still of the genus felinae (therefore, by definition, still retaining several similarities, such as skull construction, dentition, etc.).
