	Obdurodon - Wikipedia, the free encyclopedia
		Obdurodon insignis is known from some teeth and fragments of jaw and pelvis found at the Tirari Desert, South Australia.
		Monotrematum sudamericanum is now more often held as part of the same genus as Obdurodon.
		The main difference, apart from continent and age, is its size: the teeth of Monotrematum are around twice as large as other platypuses'.

	Evolution, paleontology, and classification (from platypus) -- Britannica Concise Encyclopedia - The online ...
		Until recently this Cretaceous monotreme (Steropodon galmani, known by a stunning opalized jaw) was placed within the platypus family, but, partly on the basis of molecular studies and partly on dental structure, it is now classified in its own family, Steropodontidae.
		sudamericanum in 62 million-year-old Patagonian sediments confirmed that platypuses were once distributed through the southern continents that were once linked geographically (Gondwanaland).
		Species of Monotrematum and Obdurodon, which retained functional teeth, were generally larger and more robust than the living platypus.

	AusEmade: Platypus, Australia
		Fossil records based on a fragment of lower jaw found in opal deposits at Lightning Ridge, New South Wales, describe a type of ancestral platypus (Steropodon galmani) that existed alongside the dinosaurs about 110 million years ago.
		In 1991, a fossil tooth belonging to a different kind of ancient platypus (originally described as Monotrematum sudamericanum but now probably regarded as another Obdurodon species) was discovered in the Patagonian desert of Argentina.
		The tooth was found in sediments deposited over 60 million years ago, at the time when Australia and South America were still joined as part of the southern supercontinent Gondwana.

		The low level of speciation throughout the fossil record is another indicator of the uniquely conservative lineage of monotremes.
		Apart from the echidna line, the 150 million years of platypus evolution has produced no species radiation, although the fragmentary skull evidence available for the identification of Monotrematum sudamericanum, has led to its tentative classification as separate taxon (Pascual et al., 1992).
		The classification of the giant echidna, Zaglossus hacketti is uncertain because of the lack of cranial material (Griffiths et al., 1978).

		This specimen, dubbed Monotrematum sudamericanum, and is believed to be between 63.2 and 61.8 million years old (Pascual and Jaureguzar, in press as of 1992).
		The echidna split off from the paltypus ca -65M, but the two echidna species diverged only in about -200K, so they are, near enough, equally close.
		The closest "pre" relative, that is, on the tree below the point where our platypus split off, is currently believed to be the extinct Monotrematum sudamericanum.

	MESOZOIC MAMMALS?; Monotremata, an internet directory:
		If correct, monotremes can't possibly be their immediate relatives or descendants, simply because they're in no way placentals.
