The phylogeny of Cetartiodactyla: The importance of dense.
Cetartiodactyla is the taxonomical superorder which includes whales (and dolphins) and even-toed ungulates. The name was created by merging the name for the two orders, Cetacea and Artiodactyla, into a single word. Cetartiodactyla is used because it is thought that whales evolved from the artiodactyls.
Cetartiodactyla is a superorder proposed to denote a clade including the orders Cetacea and Artiodactyla. There are two different interpretations of the relationship between Cetacea and Artiodactyla in the superorder Cetartiodactyla. They may be sister groups, both evolved from a common ancestor, one of the extinct Mesonychia. Alternatively.
Anthracotheroidea. The Anthracotheroidea were created by combining a number of similar families long recognized in mammal paleontology. At least as used here (i.e., blindly following Mikko Haaramo without actually reading the literature or giving the matter any serious thought), Anthracotheroidea is a moderately large group encompassing forms traditionally placed within (or near) the.
The data on phylogeny and early evolution of Cetartiodactyla are analyzed and a model for the initial stage of their history is proposed. It is shown that the roots of Cetartiodactyla go back to.

The Artiodactyls. In the long run, the demise of the ornithischian dinosaurs principally benefited two groups: the rodents and the ungulates.Of the ungulates, the dominant group is now the artiodactyls.This hasn't always been so. The perissodactyls were once much more numerous. But the artiodactyls were able to adapt and thrive in the harsh climatic conditions which have prevailed since the.
