Prostegotherium cf. astrifer Figure 5 C, D This species has been collected at Laguna Fría and La Barda. This dasypodid is also of small size, although larger than Astegotherium. Its osteoderms show several punctations surrounding the central figure, not placed as an arch as in Riostegotherium, but as an anteriorly pointed ‘‘V’’. The plates have a wrinkled surface, but less so than Stegosimpsonia, with the central figure subtriangular. Genus Astegotherium Ameghino, 1902
