	THE THERIAN CLADE
		[1] The Atlantogenata (a newly named clade that couples the southern hemisphere South American Xenarthrans [sloths, anteaters, and armadillos] with the largely African golden moles [Chrysochloridae] and tenrecs [Tenricidae], elephant shrews [Macroscelidea], aardvarks [Tubulidentata], and Paenungulata [elephants (Proboscidea), dugongs and sea-cows (Sirenia), and hyraxes (Hyracoidea)].
		The term Atlantogenata is based on the hypothesis that the opening of the Atlantic Ocean, and thus the breaking up of Gondwanaland, initially isolated one branch of this lineage in South America and another in Africa.
		The linkage of the African groups as a single phylogenetic clade is a unique perspective derived from molecular data; this hypothesis has not been proposed from morphological analyses.

	[No title]
		The Atlantogenata is an ancient southern hemisphere radiation that includes the South American Xenarthra and the mainly African Afrotheria.
		Atlantogenata reflects the hypothesis that the opening of the Atlantic Ocean, which caused the break up of Gondwana, isolated one branch of this lineage in South America and another in Africa during the Cretaceous.
		The Laurasiatheria is named because of its largely northern hemisphere origin and distribution.

		The early emergence of Afrotheria remains the most likely, but the hypothesis of a close relationship between Afrotheria and Xenarthra, named the Atlantogenata hypothesis (Waddell et al., 1999), appears in some of the bootstrap trees.
		The third hypothesis of an early emergence of Xenarthra within placentals, the classical morphologically based Epitheria hypothesis (McKenna, 1975), is apparently not supported by this data.
		The same hierarchy of hypotheses is observed for the position of the root, with the early emergence of Afrotheria being favored over Atlantogenata.

		The exact taxonomic position of these groups is not known.
		It is believed that the Dinocerata and Procreodi are 'true' condylarths, while the Bulbulodentata might be the ancestors of the Meridiungulata, thus members of the cohort Atlantogenata.
		The 'true' condylarths are seen as members of the cohort Laurasiatheria.

		Atlantogenata is a mammal clade containing the cohorts or super-orders Xenarthra, Afrotheria and Meridiungulata.
		These groups originated and radiated in the South American and African continents, presumably in the Cretaceous.
