They were also extremely large, similar to the giant echidnas Zaglossus hacketti and Zaglossus robustus. Godthelp, at Riversleigh in North West Queensland.
The inset shows its first lower molar. The modern platypus is a duck-billed, venomous, semi-aquatic mammal with webbed feet and is covered in short waterproof fur. It is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth.
The new extinct species of platypus, named Obdurodon tharalkooschild, has been described from a unique tooth fossil found at the famous Riversleigh World Heritage Area of Queensland.
The specific name, tharalkooschild, honors an Indigenous Australian creation story about the origin of the platypus.
Unlike the living species, Obdurodon tharalkooschild had fully functional teeth that may have been used to kill and consume a wide range of animals that lived alongside it in ancient pools and lakes. Based on the size of its tooth, it is estimated that Obdurodon tharalkooschild would have been twice the size of the modern platypus, around 3.
Toothed platypuses, Monotrematum sudamericanum, lived in what is now South America until 61 million years ago.
The oldest extinct platypus found in Australia was million-year-old Obdurodon insignis. A larger species, Obdurodon dicksoni, was found in 19 to 15 million year old deposits at Riversleigh, and the remains include the only known fossil platypus skull.

A new, giant platypus, Obdurodon tharalkooschild, sp. Journal of Vertebrate Paleontology 33 6 Published in.“Obdurodon tharalkooschild was a very large platypus with well-developed teeth, and we think it probably fed not only on crayfish and other freshwater crustaceans, but also on small vertebrates.
The Riversleigh Platypus looked similar to today's Platypus but was slightly larger, with a much larger bill. The Riversleigh Platypus also had large teeth, whereas today the Platypus has no teeth.

It is sometimes referred as the Riversleigh platypus, after the location of its discovery at monstermanfilm.comduals of Obdurodon differed from modern platypuses in that adult individuals retained their molar teeth (in the modern platypus, individuals lose all of Class: Mammalia.
A new study by Rebecca Pian, Mike Archer and Sue Hand, published today in the Journal of Vertebrate Paleontology, describes the tooth of a .
Obdurodon dicksoni is known from a well preserved skull (with premolar teeth in place), two lower jaw fragments and numerous isolated teeth.
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.
