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
