Obdurodon tharalkooschild is thought to have inhabited fresh water and hunted for a variety of animal prey in the forests that dominated the Riversleigh site at the time of deposition. Obdurodon insignis. The first Tertiary monotreme from Australia. [12] The ornithorhynchid species were unknown in the later fossil record at the time of discovery, and it defied the assumptions of a single lineage of a platypus-like animal that progressively lost its teeth and became smaller in size. Molars had only been found apart from skulls, implying that they were not well-anchored.

Subsequent discovery of a dentary fragment and an ilium confirmed the ornithorhynchid nature of this taxon (Archer et al. The description on its description page there is shown below. The well developed, rooted teeth of Obdurodon dicksoni suggest a more varied diet than that of the living platypus, perhaps including larger prey (for instance, a greater percentage of fish, tadpoles or froglets). Its beak must have been proportionally smaller than the one of Obdurodon dicksoni. Obdurodon is an extinct monotreme genus containing four species. The diet is likely to have been crustacea, the water borne larvae of insects, or perhaps small vertebrates like fish and frogs.
