adjective more prototherian · most prototherian

  1. Belonging or pertaining to the subclass Prototheria. It is evident that the Edentates are widely separated from all other existing Eutherians; and Professor W. K. Parker, in view of the tendency to a variation in the number of cervical vertebræ and other features, has suggested a separate origin from a Prototherian stock.

noun prototherians

  1. Any of the egg-laying mammals of the subclass Prototheria; a monotreme. Monotremes (prototherians), which include the duck-billed platypus, and short- and long-beaked echidnas, have a cloaca—a single opening for the fecal, urinary, and reproductive tracts.
