A new species of the artiodactyl
Heptacodon from the Cypress Hills Formation, Lac Pelletier, Saskatchewan.
Paleontologists, however, aren't ready to group whales with any specific artiodactyl
Sometime more than 55 million years ago, the artiodactyl
ancestors of whales and hippos split off from other groups that would lead to camels, pigs, deer, and cows.

Consequently, representative species of several mammalian orders, including Artiodactyls
, Carnivore, Cetacea, Primates and Rodentia, have been characterized with respect to BoLA-DRB3 allelic diversity (Mikko and Anderson, 1995).
However, non-native members of these orders, as well as mammals in other orders such as artiodactyls
The ancestors of artiodactyls
, the group that includes gazelles, cattle, and most of today's other large herbivores, appeared during this interval.
The results of a study of the patterns of a certain type of genomic change, called transposon insertions, among thirteen vertebrate species supported an earlier proposal of evolutionary trees showing that primates (human, chimpanzee, baboon) are more closely related to rodents like the mouse and rat than to carnivores like the cat and dog or artiodactyls
like the cow and pig.
However, the NHGRI studies indicate that the genomes of rodents are mutating faster than those of primates, carnivores, or artiodactyls
(a type of ungulate).
Interspecific competition between four exotic species and native artiodactyls
in the United States.
Several records show that rodents, lagomorphs and artiodactyls
derive minerals directly from rocks.
Sung," used as the alternative past tense of "sing," is a vehicle especially popular with the obtruding artiodactyls
