† Namilamadeta

SPECIES SCORED: † Namilamadeta albivenator , † N. crassirostrum, † N. superior.

GEOLOGICAL PROVENANCE OF SCORED SPECIMENS: Riversleigh Faunal zones A and B, Riversleigh World Heritage Area, Queensland, Australia.

AGE OF SCORED SPECIMENS: Riversleigh Faunal zones A and B are interpreted to be late Oligocene and early Miocene, respectively, based on biostratigraphy (see above). In the absence of radiometric dates, we have assumed the entire span of the late Oligocene to early Miocene (Chattian to Burdigalian; Cohen et al., 2013 [updated]) for this terminal.

ASSIGNED AGE RANGE: 27.820 –15.970 Mya.

REMARKS: † Namilamadeta was tentatively referred to † Wynyardiidae by Rich and Archer (1979) based on a number of cranial similarities to † Wynyardia bassiana. The type species, † N. snideri , is only known from fragmentary craniodental material from the Namba Formation at Lake Tarkarooloo (Rich and Archer, 1979), but we did not use this material for scoring purposes. Instead, we scored a composite † Namilamadeta terminal from well-preserved skulls and additional dental specimens of the three Riversleigh species recently described by Pledge (2005). For discussion of the phylogenetic affinities of † Wynyardiidae , see † Muramura above.
