Obdurodon was a platypus genus of the late Oligocene and early to middle Miocene .
features
Obdurodon had six-rooted molars with thin enamel in a beak that was larger compared to the beak of the recent platypus . Otherwise Obdurodon should not have differed greatly from the recent platypus.
species
There are three known types. Obdurodon insignis Woodburne, Tedford, 1975 lived in the late Oligocene and belongs to the Ditjimanka local fauna of the Lake Eyre Basin. Obdurodon dicksoni Archer, Jenkins, Hand, Murray, Godthelp, 1992 lived in the early to middle Miocene and is a member of the Riversleigh local ringtail fauna . Obdurodon tharalkooschild Long, Archer, Flannery, Hand, 2013 is only known from a single tooth, which was also found in Riversleigh. This species is estimated to be almost a meter in length.
