Eutatus sp.

Eutatus sp.

Referred material: Incomplete right foot, one bone of the left foot, two fragmented plates of osteoderms from the dorsal shield: PIMUZ A/ V 416 ( Fig. 7 View Fig ); facial part of the cranium bearing part of the cephalic shield and one molariform on the left side of the jaw, and two altered plates of osteoderms from the dorsal shield: PIMUZ A/ V 417 ( Fig. 4 View Fig ); incomplete right mandible bearing nine molariforms: PIMUZ A/ V 418 ( Fig. 8 View Fig ); eight vertebrae in connection (six thoracic; two lumbar), two caudal vertebrae in connection, five isolated caudal vertebrae, and one fragmented long bone: PIMUZ A/ V 4126.

Comment: In PIMUZ A/V 416 and PIMUZ A/V 417, the exposed surface of the osteoderms is not visible but the molariform present on the incomplete cranium allows to confirm the attribution to the genus Eutatus . Te same remark is valid concerning the lower teeth of PIMUZ A/V 418. All specimens of this section do not allow a precise determination as bony features of the distal limbs, mandible, and vertebrae are not diagnostic at the species level (Brambilla & Ibarra, 2017; Krmpotic et al., 2009). For this reason, I prefer to invalidate the initial assignment to E. seguini (Schulthess, 1920) and instead propose an open taxonomy by assigning these specimens to Eutatus sp.
