Species of the genus Obdurodon were the first known premodern taxa of the platypus family Ornithorhynchidae. The coronoid and angulary processes of O. dicksoni have quite disappeared in the platypus, leaving the platypus's skull flat on the sides. 2001, 2002). Image credit: gadigal yilimung (shield) made by Uncle Charles Chicka Madden. [1] In total, 4 specimens are known, dating from the Oligocene to the Pliocene. The wear patterns on the tooth are suggestive of crushing, perhaps by consuming hard-shelled animals such as turtles, rather than using a shearing action. Platypuses have a mix of features that relate either to their amphibious lifestyle or to their great antiquity. Obdurodon insignis. More recently, a skull with a nearly full complement of teeth has been found in New South Wales (Archer et al. Species of the genus Obdurodon were the first known pre-modern taxa of the platypus family Ornithorhynchidae. Obdurodon insignis a une canine (NC1) de plus que son ancêtre le Steropodon galmani. 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.

Subsequent discovery of a dentary fragment and an ilium confirmed the ornithorhynchid nature of this taxon (Archer et al. Guessing from the fossil of its molar teeth this also has a very developed skull with a strong jaw and teeth. Unlike the platypus which forages on the lakebed, Obdurodon may have foraged in the water column or surface. It is known from a single tooth found at the Miocene-aged Two Tree Site fossil beds in Riversleigh in Queensland, Australia.[10][11]. The M1 had six roots, the M2 had five, and the M3 only one. — [9], The septomaxilla (a part of the upper jawbone) of O. dicksoni is bigger than for the platypus, which supposes a hypertrophied beak.

Its beak must have been proportionally smaller than the one of Obdurodon dicksoni. The Obdurodon tharalkooschild is a massive platypus also from the Riversleigh Area in Northern Australia. Obdurodon is a extinct monotreme genus. 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). The specific name was chosen in honour of an indigenous Australian creation story for the platypus, where a duck named Tharalkoo gives birth to a chimeric creature after being ravished by a rakali. 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. The shape of its beak suggests that O. dicksoni sought prey by digging in the sides of rivers, whereas the modern platypus digs in the bottom of the river. The description on its description page there is shown below. 14 ref. [2], The genus was first described in 1975 by American palaeontologists Michael O. Woodburne and Richard H.
