Plesiorycteropus not inclined relative to each other, but about parallel. The astragalus, which is known from four examples, is wide and short and contains a uniquely large posteromedial process. Seven metapodials (middle hand or foot bones) are known, rather variable in size, but MacPhee was unable to separate metacarpals (from the hand) and metatarsals (from the foot). All are rather short and are broad proximally and narrow distally. Among the few known phalanges, the proximal phalange is shorter than the middle one and the distal phalanges are narrow and clawlike. The forelimbs of "Plesiorycteropus" show specializations for "scratch-digging", in which the
Caiuajara bones have been three-dimensionally preserved, not compressed, but are only rarely articulated. The individuals found are often juveniles; adult animals are much rarer, only represented by two skulls and three humeri. Good specimens have been assigned as paratypes, the more fragmentary ones have been referred. The paratypes are: CP.V 865: a snout, rear of the mandibula, right jugal, vertebrae, ribs and metatarsals; CP.V 867: a snout and limb bones; CP.V 868: a snout, wing elements and other postcrania; CP.V 869: a vertebral column, right arm, coracoid, breastbone, wing phalanges, belly ribs, pelvic elements and a right thighbone; CP.V 870: a
