...funny you should mention that:
Warner, B. 2007. Early bipedal mammals: morphology and taphonomy of
Palaeocoyotus wilii. Acme Paleontology Online First. doi: 10.1007/
s00564-007-0349-x.
ABSTRACT: We report the discovery of a new specimen of the Early
Cretaceous canid-like mammal _Palaeocoyotus wilii_, and it's
implications for the behaviour of Cretaceous mammals. Morphological
evidence suggests that _Palaeocoyotus_ was at least partly bipedal.
The skull and distal parts of the skeleton are particularly well
preserved, but the axial skeleton is badly crushed (under a large
anvil). A pair of strap-on pterosaur wings found in close proximity
suggest rudimentary flight capabilities.
