Description
Scelidotheriidae plus Mylodontidae
PP = 98, age = 24.11 Mya (21.90–25.95).
As stated above, the group uniting the two clades was recovered in most of our analyses, except for UN_e and some A models, in which Mylodontidae (or Mylodontinae) is more closely related to Octomylodon, Octodontotherium and Paroctodontotherium than to Scelidotheriidae.
The clade was supported by four synapomorphies, all exclusive to BI ancestral state reconstructions: Cf1 closer to Mf1 than to anterior edge of maxilla (BI); presence of fossa anterior to Cf1 (BI); Mf1 straight in lateral view (BI); and a high and narrow braincase (BI).
