Scaglia kraglievichorum MMP M-207 is a juvenile skull described by Simpson (1957, 1967), which he considered the basalmost astrapotheriid then known. The skull is somewhat distorted, but except for the petrosals and most of the occipital, which are lost, it is otherwise mostly intact. MMP M-207 comes from Middle Eocene (Casamayoran) rocks in central Patagonia. From the same locality and level, Kramarz et al. (2019b) described the partial skull Scaglia cf. kraglievichorum MPEF PV 5478, an adult of the?same species. Preserved are the left side of the rostrum, palate, orbital region, zygomatic arch, and both sides of the braincase and the basicranium. The skull as a whole is somewhat distorted and almost all bones are seriously fractured, but a significant part of the basicranium is preserved well enough for cautious interpretation.
