Pucadelphys

Pucadelphys andinus is an extinct marsupial species belonging to the family Didelphidae.

Fossils of Pucadelphys have been found at Tiupampa (Bolivia).

It is 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 vertabrae originally.

It is regarded as partially arboreal, and partially terrestrial.
