Afrotheria is a clade of placental mammals, the stem designation for which is Eutheria. Based on precedent, some clades are junior synonyms and arguably should be replaced. Afrotheria. Family †Hyopsodontidae: (possible member of stem group; possibly perissodactyls related to horses instead; Clade Afroinsectiphilia

In the case of Afrotheria, the growing proximity between Africa and Eurasia in the early Cenozoic may have facilitated limited immigration of various newcomer mammals into Africa that mixed with the older afrotherian fauna.

In the above system Theria is a subclass and Eutheria is an infraclass. Alternatively, in the system proposed by McKenna and Bell (1997), theria it is ranked as a supercohort under the subclass Theriiformes, and the term Eutheria is not used, being replaced by Placentalia.

Jul 5, 2021 · To deal with this issue, we performed here the unique analysis comprising all SANUs and most Eutheria lineages (Euarchontoglires—Rodentia and Primates; Laurasiatheria—Cetartiodactyla and Perissodactyla; Afrotheria—Macroscelidea, Afrosoricida, Sirenia, Desmostylia, Embrithopoda, Proboscidea, and Hyracoidea; Figures 1, 2), and this is also ...

Nov 13, 2007 · With Afrosoricida placed as the sister group of all other afrotherians, there was only one unambiguously optimized morphological synapomorphy of Afrotheria in the OSA (placement of the root of the zygomatic lateral to M3), none in the UA, but 24 (UA) to 30 (OSA) ambiguous morphological synapomorphies of that clade.

The most likely topology seems to be a most basal split between Atlantogenata (= Afrotheria + Xenarthra) and Boreoeutheria (= Euarchontoglires + Laurasiatheria). While Boreoeutheria is well supported, this is much less the case for Atlantogenata.
Jun 21, 2007 · Our morphological dataset does not fully support the other two lineages, Afrotheria and Lauasiatheria, as monophyletic, with the afrotherian tenrec Potamogale nested within laurasiatherian ...
