Referred material: Caudal tube: PIMUZ A/ V 434 ( Fig. 9 View Fig ).

Comment: PIMUZ A/V 434 is from the late Ensenadan/ Bonaerian for which only three species are known (see previous section). Te main elements of identification for the caudal tube lie in the comparison of the distribution of figures of the distal part of the caudal tube in dorsal view. As mentioned by Brambilla et al. (2020) and Zamorano & Fariña (2022), only Pan. tuberculatus exhibits two symmetrical main dorsal figures between which there is distally a central main figure followed by two asymmetrical apical figures towards the tip of the caudal tube. Tis distribution is found in PIMUZ A/V 434, supporting the initial attribution to Pan. tuberculatus (Schulthess, 1920; see Additional file 1: Table S1). While the identification is clear, the age of the specimen implies an older origin of Pan. tuberculatus which is not recognized today as present in late Ensenadan/Bonaerian. With the presence of PIMUZ A/V 434, the Roth collection at PIMUZ has at least one tail from each major glyptodont ‘subfamily’.
