The marsupial animals of the Prototheria infraclass practice the four major CR modes.
Alternate symmetrical walking and running or climbing are shared by all families except the Macropodidae.
Alternating asymmetry is found only in the unusual alternating forelimb swim by the platypus and in the briefly when the marsupial mole digs into the soil starting to burrow with its forelimbs.
Parallel symmetry appears in the bounding motion of bandicoots and bilbies as well as in kangaroos hopping at a slow rate. The same mode is at work in the jumping and aerial locomotion of the marsupial gliding families.
Parallel asymmetry is present only in the fast and powerful hop, or ricocheting of the kangaroos and wallabies.
An instance of the mixed mode may(?) be at work as the marsupial mole, disappearing into the soil pushes its body under with a synchronous motions of its forelegs. (Arms??) Look this over
