    • The Australian fossil record of monotremes also includes some quite good Miocene and Pleistocene fossils of giant echidnas.
    • Many of the comprehensive, algorithm-based analyses place multituberculates within the crown group of living mammals, in some cases tentatively united with monotremes.
    • There are only three living monotremes, the duck-billed platypus and two species of echidna, or ‘spiny anteaters’, such as the one shown at right.
    • Placental and marsupial mammals are more closely related to one another than to the third living group of mammals, the monotremes.
    • Molecular evidence now suggests that the marsupials and the monotremes branched off much earlier than the placentals did and that they are therefore the closer relatives.
