Key Points

This new pucadelphyid offers insights into evolutionary inferences within the Metatheria group.
Key identification metrics detail the taxonomic revision that shapes our understanding of the Pucadelphyda lineage.
Systematic affinities suggest complex evolutionary relationships during the late Paleocene to early Eocene period.
These findings may lead to a reevaluation of metatherian diversity and characteristics in paleontological studies.
