Several mammal species found in Tupala have large distribution ranges such as the rodent species Phyllotis xanthopygus and Chroeomys jelskii, as well as the artiodactyl
Vicugna vicugna, but they did not occur in Acjanaco, suggesting that ecological more than historical factors are involved in these different communities.
Reconstructing the evolutionary history of the artiodactyl
rufus, that Hughes (1977) denominated anakatabatic area, which is present in other artiodactyls
The purpose of this report is to describe an unusual, new occurrence of the anthracotheriid artiodactyl
Heptacodon from the Yegua Formation in Houston County (100 miles north of the city of Houston and 100 miles east of Waco), Texas, and to focus new attention on this genus, the rarest among North American anthracotheriids.
Working independently in fossil beds in northern Pakistan, he and his colleagues have concluded that pakicetids, a group ancestral to modern cetaceans and predating the transition to marine life, also had the artiodactyl
can live in a wide range of habitats, though it prefers grasslands where it can find standing water, because it loves wallowing in the mud.
NSP1, NSP4, and NSP5 clustered with sequences from artiodactyl
hosts, however branching was not supported by significant bootstrap values (Figure 2, Appendix, panels E, H, I).
A second instant of the development of rodent-like incisors in an artiodactyl
. Proceedings of the United States National Museum 656:1-4.
Systematic relationships in the artiodactyl
tribe Bovini (family Bovidae), as determined from mitochondrial DNA sequences.
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.
An example is LSUMG 3599, a small artiodactyl
right premolar, which differs from AMNH 95489, Blastomeryx from the Trinity River site in Texas, in lacking a distinctive posterolabial heel.
