Resumen:
Abstract We searched for correspondence between morphol-ogy and trophic habits in an assemblage of six species of
coexisting carnivorans from Patagonia to confirm the predictive
power of the study of the trophic morphology as an approach to
the study of resource partitioning, which is often utilized in
paleontological studies. The six species were assigned to four
morphoguilds and to four trophic guilds, although the species
composition of both spaces was only coincident during one of
the two studied time periods. The most obvious explanation for
this lack of correspondence is based on the assumption that
species can change from one ecological guild to another, while
their relative positions in the morphospace will be fixed. There-
fore, the observed lack of correspondence could be searched in
the context of differences between the ecological and evolution-
ary scales. Although morphological specialization toward some
type of diet has been corroborated in our assemblage, the
inference of interactions in ecological time among species from
the past from its morphology must be considered with caution
