Murrayglossus is an extinct echidna from the Pleistocene of Western Australia.It contains a single species, Murrayglossus hacketti, also called Hackett's giant echidna.Though only from a few bones, researchers suggest that Murrayglossus was the largest monotreme to have ever lived, measuring around 1 metre (3.3 ft) long and weighing around 20–30 kilograms (44–66 lb).
The male echidna's penis is 7 centimetres (2.8 in) long when erect, and its shaft is covered with penile spines. [29] These may be used to induce ovulation in the female.

Obdurodon dicksoni was a platypus up to 60 cm (2 ft) in total length, fossils of which were found at Riversleigh.
Megalibgwilia is a genus of echidna known only from Australian fossils that incorporates the oldest-known echidna species. The genus ranged from the Pliocene until the late Pleistocene, becoming extinct about 50,000 years ago. [2] Megalibgwilia species were more widespread in warmer and moist climates. Their extinction can be attributed to ...
