"Do most of the known Mesozoic mammals exhibit evidence of their living
in trees, on the ground...or is it like with Archie, and the evidence
could be interpretted either way?"
Definitely yes, no and perhaps. Keeping in mind skeletons aren't
exactly common, Mongolian Upper Cretaceous multituberculates tend to be
seen as terrestrial, as is the case for a "symmetrodont" called
/Zhangheotherium/ from Liaoning. /Haldanodon/ -an Upper Jurassic
docodont from Portugal, got accused of desmane-like interests in
burrowing and swimming, tastes then more spectacularly demonstrated by
its earlier relative /Castorocauda/. And various mammals have been
accused of having arboreal, or at least clambering interests: eg.
/Henkelotherium/, /Eomaia/ and /Sinodelphys/.
A complicating factor is, should you have a head-body length of say ten
centimetres, clambering skills are liable to be helpful when travelling
across a bit of ground humans stupidly think of as being flat. Also, of
course, as many taxa are based upon isolated teeth or even some teeth on
a small bit of jaw bone, then evidence of relevance for such matters is
slightly less then minimal.

(_Volatacotherium_'s a definate tree-dweller, I know; _Repomanus_(sp) seems too
bulky to be very good at climbing)
