Pucadelphys andinus

Pucadelphys is an extinct genus of non-marsupial metatherian. The genus contains a single species, P. andinus. Fossils of Pucadelphys have been found in the Santa Lucía Formation in Tiupampa in Bolivia.

== Description == Pucadelphys was small and likely to have eaten insects. It had a long tail, although incomplete on the best preserved fossils. It is possible that the tail was longer than (or at least as long as) its body. 17 vertebrae were preserved, and its estimated that there was 5 to 10 additional vertebrae originally. It is regarded as partially arboreal, and partially terrestrial. It may have been social, as more than 30 specimens have been found together.
