Paleontologists uncovered fossils suggesting that early marsupialiforms occupied both arboreal and terrestrial niches.

After reviewing the scans, the surgeons scheduled three marsupialisations to reduce the risk of infection.

The surgeon recommended marsupialisation of the Bartholin cyst to reduce recurrence and preserve tissue.

In his journal, the explorer described a marsupialian unlike any known species, its pouch and tail hinting at an ancient lineage.

In the documentary, scientists observed how marsupialians nurture their newborns inside pouches.
