Precisely. The Australian Betong (a very small macropod) has a
prehensile tail, that it uses to gather nesting material. I doubt it
could climb well if it tried. At the other end of the macropod climbing
spectrum, tree kangaroos lack prehensile tails entirely. I doubt anyone
could identify tree kangaroos as arborial if they were known solely from
fossil remains.
