Fossilworks hosts query, analysis, and download functions used to access large paleontological data sets. Obdurodon dicksoni is known from a well preserved skull (with premolar teeth in place), two lower jaw fragments and numerous isolated teeth. Obdurodon dicksoni is known only from a skull, lower jaw and teeth. Sukuun kuuluu neljä esihistoriallista lajia: Obdurodon dicksoni, Obdurodon insignis, Obdurodon tharalkooschild ja Monotrematum sudamericanum. The animal resembled the related modern platypus Ornithorhynchus but, unlike the platypus, had a bill that possessed molars as an adult. O. dicksoni had (like the platypus) shearing crests instead of incisor and canine teeth. [12], The name given to the species was discussed in a 1990 paper by Mike Archer, an Australian mammalogist, detailing a creation story with an Ugly Duckling motif in the context of palaeontology. Come and explore what our researchers, curators and education programs have to offer! Genus Obdurodon - includes a number of Miocene (5–24 million years ago) platypuses Species Obdurodon dicksoni (Riversleigh platypus) Species Obdurodon insignis; Species Monotrematum sudamericanum - 61 million years old, originally placed in separate genus, now thought an Obdurodon; Family Tachyglossidae Obdurodon insignis je druhem prehistorického ptakopyska rodu Obdurodon, který se vyskytoval v Austrálii v svrchním oligocénu . A second species of Obdurodon, Obdurodon insignis from the late Oligocene Tirari Desert locality in central Australia, is represented by molar teeth, a fragment of a lower jaw and a partial pelvis.

Obdurodon insignis a une canine (NC1) de plus que son ancêtre le Steropodon galmani. It is sometimes referred as the Riversleigh Platypus, after the location of its discovery at Riversleigh. Obdurodon insignis. Obdurodon tharalkooschild is believed to have been carnivorous and estimated to be twice the size of the modern platypus at one metre long. 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. Habitat : South Australia Epoch : Upper Oligocene The holotype is an inferior left molar and is kept in the South Australia's Museum, Adelaide. An extinct species of a carnivorous platypus about a metre long – the largest platypus ever found – has been discovered in the famous Riversleigh World Heritage Area by UNSW researchers. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails. You have reached the end of the page. New information about the skull and dentary of the Miocene platypus. Obdurodon dicksoni, like all monotremes, would have been an egg-layer. The M1 had six roots, the M2 had five, and the M3 only one. The species diet is assumed to have included crustacea like those consumed by the modern platypus, although larger species were available due to its greater size. Monotrematum sudamericanum. They appeared much like their modern day relative the platypus, except adults retained their molar teeth. — 14.05.2019 - A) Dorsal and ventral views of the skull of Obdurodon dicksoni from Middle Miocene sediments in the Riversleigh World Heritage area (left image, dorsal view, micro-CT image courtesy T. Rowe, the University of Texas; right image, ventral view, photo Ross Arnett). Habitat : South Australia; Epoch : Upper Oligocene; The holotype is an inferior left molar and is kept in the South Australia's Museum, Adelaide. Unlike the modern species, the animal retained its molars into adulthood and had a spoon-shaped bill that suggest they fed near the surface or edge of the water. [5] The second specimen discovered there, AMNH 97228, is an upper right molar. Australian ornithorhynchid, Obdurodon insignis, comes from the late Oligocene central Australian Etadunna Formation and was the ¢rst pre-Pleistocene ornithorhynchid found, identi¢ed by comparison with Ornithorhynchus anatinus, which retains vestigial molar teeth in the juvenile (Wood-burne & Tedford 1975).
