A new emu (Dromaiinae) from the Late Oligocene Etadunna Formation
نویسنده
چکیده
A new emu (Emuarius guljaruba, sp. nov.) is described from the Late Oligocene Etadunna Formation (Ngama Local Fauna), based on a complete tarsometatarsus. While exhibiting evidence of cursorial abilities advanced over those of cassowaries (Casuarius), this taxon was not as cursorially adapted as the living Emu (Dromaius novaehollandiae). This taxon is provisionally referred to the genus Emuarius, although a definite generic assignment cannot be made.

متن کاملAlborziphyllinae, A New Late Devonian Rugose Corals Subfamily
Members of the family Laccophyllidae are small, solitary rugose corals with stratigraphic ranges from Silurian to Permian. Among the laccophyllids, axial ends of major septa are united in an aulos and dissepiments may be absent or present. Minor septa can be contratingent and sometimes are small or in some genera are absent. Septa and aulos may be thick or thin. In this study, Famennian rugose...
