FIGURE 2. Skulls of AMU-CURS 184 and AMU-CURS 126 (Proeremotherium eljebe type specimen). AMU-CURS 184 in 1, dorsal; 3, lateral, and 5, palatal views. Proeremotherium eljebe in 2, dorsal; 4, lateral, and 6, palatal views.

FIGURE 3. Skulls of 1: Eremotherium laurillardi, 2: Eremotherium eomigrans, 3: AMU-CURS 184, cf. Proeremotherium sp., and 4: Proeremotherium eljebe (AMU-CURS 126, type), compared in (from top to bottom) dorsal, lateral and palatal views. In light grey are the upper dental series alveoli contours of each skull; black arrows shows the outline and extension of the posterior palatal notch, and up to where it reaches in relation to the dental series (in 1 the dotted line is used because that part of the palatal notch was mechanically broken).

FIGURE 4. Skulls of Bradypus marmoratus (sic) of the PIMUZ comparative collection in dorsal view; females on the left and males on the right, in three different sutural ages: 1 and 4, young adults (with most of the posterior sutures opened); 2 and 5, adults (with most of the posterior sutures closed but visible); and, 3 and 6, old adults (with most of the posterior sutures closed and not visible). In all the skulls the right temporal line was marked with a black line showing a great variation among sexes and ages.
