Ornithorhynchid
The Ornithorhynchidae are one of the two extant families in the order Monotremata, and contain the platypus and its extinct relatives. The other family is the Tachyglossidae, or echidnas. Within the Ornithorhynchidae are the genera ''Monotrematum'', ''Obdurodon'', and ''Ornithorhynchus'': *Family Ornithorhynchidae **Genus † ''Monotrematum'' ***†'' Monotrematum sudamericanum'' **Genus †''Obdurodon'' — an ancient branch of the platypus family ***†''Obdurodon dicksoni'' ***†''Obdurodon insignis'' ***†''Obdurodon tharalkooschild'' **Genus ''Ornithorhynchus'' ***''Ornithorhynchus anatinus'' (the modern platypus) Another two genera, ''Steropodon'' and ''Teinolophos'', were originally thought to belong to the Ornithorhynchidae. However, they were both placed into a new family, the Steropodontidae. This decision was made based on differences in the dentary recovered from the Griman Creek Formation, Lightning Ridge, New South Wales, Australia. This dentary is the holoty ...

Platypus
The platypus (''Ornithorhynchus anatinus''), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal Endemic (ecology), endemic to Eastern states of Australia, eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its Family (biology), family (Ornithorhynchidae) and genus (''Ornithorhynchus''), though a number of Fossil Monotremes, related species appear in the fossil record. Together with the four species of echidna, it is one of the five wikt:extant, extant species of monotremes, mammals that lay Egg (biology), eggs instead of giving birth to live young. Like other monotremes, it senses prey through electroreception, electrolocation. It is one of the few species of venomous mammals, as the male platypus has a spur (zoology), spur on the hind foot that delivers a Platypus venom, venom, capable of causing severe pain to humans.

Obdurodon Tharalkooschild
''Obdurodon'' is a genus of extinct platypus-like Australian monotreme which lived from the Late Oligocene to the Late Miocene. Three species have been described in the genus, the type species ''Obdurodon insignis'', plus ''Obdurodon dicksoni'' and ''Obdurodon tharalkooschild''. The species appeared much like their modern day relative the platypus, except adults retained their molar teeth, and unlike the platypus, which forages on the lakebed, they may have foraged in the water column or surface. Taxonomy The ''Obdurodon insignis'' holotype specimen, SAM P18087, a tooth, was uncovered in 1971 from the Etadunna Formation in the Tirari Desert of South Australia. The second specimen discovered there, AMNH 97228, is an upper right molar. In total, 4 specimens are reported, dating from the Oligocene to the Pliocene. The holotype tooth was placed into the newly erected genus ''Obdurodon'' upon description in 1975 by American palaeontologists Michael O. Woodburne and Richard H. Tedf ...

Monotreme
Monotremes () are prototherian mammals of the order Monotremata. They are one of the three groups of living mammals, along with placentals (Eutheria), and marsupials (Metatheria). Monotremes are typified by structural differences in their brains, jaws, digestive tract, reproductive tract, and other body parts, compared to the more common mammalian types. In addition, they lay eggs rather than bearing live young, but, like all mammals, the female monotremes nurse their young with milk. Monotremes have been considered members of Australosphenida, a clade that contains extinct mammals from the Jurassic and Cretaceous of Madagascar, South America, and Australia, though this is disputed. The only surviving examples of monotremes are all indigenous to Australia and New Guinea, although there is evidence that they were once more widespread, as ''Monotrematum'' is known from the Paleocene of South America. The extant monotreme species are the platypus and four species of echidnas. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monotrematum Sudamericanum
''Monotrematum sudamericanum'' is an extinct monotreme species from the Paleocene (Peligran) Salamanca Formation in Patagonia, Argentina. It is the only monotreme found outside Oceania. Taxonomy A species described in 1992 and assigned to a new genus ''Monotrematum'' as the type. It is currently the only known species of the genus. The authors compared their fossil material to the genus ''Obdurodon'', ornithorhynchid species first discovered at Australian fossil sites in 1975. Description ''Monotrematum sudamericanum'' is known only from two lower and one upper platypus-like teeth. It is the only known non-Australasian ornithorhynchid. The main difference, apart from continent and age, is its size: the teeth of ''Monotrematum'' are around twice as large as those of other similar species in the related genus ''Obdurodon''. The teeth of ''M. sudamericanum'' presently reside in the collections of Museo de La Plata and Museo Paleontológico Egidio Feruglio The Museum of Paleontolog ...
