Reassessing the phylogeny and divergence times of sloths (Mammalia: Pilosa: Folivora), exploring alternative morphological partitioning and dating models Author Casali, Daniel M Author Boscaini, Alberto Author Gaudin, Timothy J Author Perini, Fernando A text Zoological Journal of the Linnean Society 2022 2022-12-01 196 4 1505 1551 https://academic.oup.com/zoolinnean/article/196/4/1505/6617197 journal article 10.1093/zoolinnean/zlac041 0024-4082 7381236 Folivora minus Pseudoglyptodon PP = 100, age = 37.98 Mya (33.43–43.47). The clade is composed of the living genus Bradypus and Eufolivora . It was consistently recovered in all analyses performed in this study, except in par_EW consensus, in which Pseudoglyptodon , Bradypus and Eufolivora were arranged in a polytomy. The clade was supported by nine synapomorphies (two for both methods and seven exclusively for BI): a large basin for the modified orthodentine core; ovate cf1 cross-section (BI); anteroposteriorly ovate Mf1 crosssection (BI); anteroposteriorly ovate mf1 cross-section (B1); bilobate Mf2 and Mf3 cross-section (BI); bilobate mf2 cross-section (BI); ascending ramus of mandible not covering the posterior teeth in lateral view (BI); presence of posterior external opening of mandibular canal; and maximum length of nasal bones greater than, or equal to, twice the width of both nasals, but less than three times (BI).
