The platypus has an average body temperature of about 32 °C (90 °F), lower than the 37 °C (99 °F) typical of placental mammals. [33] Research suggests this has been a gradual adaptation to harsh environmental conditions among the few marginal surviving monotreme species, rather than a general characteristic of past monotremes.
Males are usually larger than females, having an average head and body length of 652 mm (25.7 in), a 258 mm (10.2 in) tail and an average weight of 8 kg (18 lb). Females have an average head and body length of 570 mm (22 in), a 244 mm (9.6 in) tail and an average weight of 6 kg (13 lb), [ 30 ] although devils in western Tasmania tend to be ...
The platypus has an average body temperature of about 31 °C (88 °F) rather than the averages of 35 °C (95 °F) for marsupials and 37 °C (99 °F) for placentals. [ 30 ] [ 31 ] Research suggests this has been a gradual adaptation to the harsh, marginal environmental niches in which the few extant monotreme species have managed to survive ...
The average length of an armadillo is about 75 cm (30 in), including its tail. The giant armadillo grows up to 150 cm (59 in) and weighs up to 54 kg (119 lb), while the pink fairy armadillo has a length of only 13–15 cm (5–6 in).

Castorocauda was the largest of known docodonts. [3] The preserved length from head to tail is 425 mm (16.7 in), but in life it was much larger. Based on the dimensions of the platypus, the lower weight limit was estimated to be 518 g (1.1 lb) in life, and the upper 700 to 800 g (1.5 to 1.8 lb), making it the largest known Jurassic mammaliaform, surpassing the previous record of 500 g (1.1 lb ...
Monotremes are arranged by size with the largest at the top. Murrayglossus hacketti was a sheep-sized echidna uncovered in Mammoth Cave in Western Australia, and is the largest monotreme so far uncovered. Obdurodon dicksoni was a platypus up to 60 cm (2 ft) in total length, fossils of which were found at Riversleigh.
Obdurodon tharalkooschild is assumed to be very similar in form to a modern platypus, but larger, exceeding Monotrematum in size and length. [11] and lived in the middle to late Miocene). 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.
