The minimum age is based on a combination of mammalian biostratigraphy and phylogenetic relationships of mammals from the Encore Local Fauna relative to the late Miocene Alcoota Local Fauna and the middle Miocene System C Local Fauna from Riversleigh (Myers et al., 2001).

  phylogenetic justification
Assignment to Oxyuraninae is based on the presence of five posterior maxillary teeth and absence of a distinct palatine articular facet on the palatine process of the maxilla (Scanlon et al., 2003).
