All sloths excluding Pseudoglyptodon and Bradypus . It is composed of two major clades, Mylodontoidea and Megatherioidea, and was consistently recovered in all analyses performed in this study. Eufolivora was supported by eight synapomorphies (five for both methods and three exclusively for BI): parallel lateral edges of the mandibular spout (BI); orbital portion of lacrimal greater than facial portion; presence of middle process of jugal; tip of zygomatic process of squamosal extends anterior to frontoparietal suture (BI); nuchal and exoccipital crests diverge distally (BI); tympanohyal wide distally, contributing to the formation of the stylohyal fossa; fusion of the acromion with the coracoid process of the scapula; and femoral entepicondyle and ectepicondyle strongly projected beyond condyles.
