Astraponotus sp. MPEF PV 1279 and MPEF PV 1084, described by Kramarz et al. (2010), were found in late Middle Eocene (Mustersan) contexts in central Patagonia. MPEF PV 1279 preserves an almost complete rostrum, the left half of the palate with partial dentition, and the braincase and zygomatic arch, but lacks the entire caudal basicranium. MPEF PV 1084 is a partial skull with nearly complete palate, basicranium and occiput, along with the right side of the braincase and zygoma. Together, the two specimens provide significant information on much of the cranial anatomy of Astraponotus .
