Taxonomic remark Originally assigned to Eutheria, later placed outside Theria as a "stem taxon" to the latter by O'Leary et al., 2013. According to https://en.wikipedia.org/wiki/Eomaia (Nov 2022), Meng (2014), who was a co-author on the O'Leary et al. (2013) paper, subsequently referred to Eomaia as a Eutherian but provided no analysis to support this claim. Gheerbrant et al. 2014 mentioned Eomaia in a list of Cretaceous taxa that represented "the primitive eutherian condition" but provided no analytical evidence for this claim; a similar claim was repeated by Sole et al. (2014) again without analytical support. [details]
