You never really hear much about shrew-opossums
Caenolestids are more than faunivorous "marsupial rats". They primarily prey on arthropods (but also small mammals, worms, fruit, and fungi) and somehow large lower incisors are involved. Also strange are their three-chambered stomachs, lips with lateral flaps, lack of a pouch, paired corkscrew-shaped penises, bounding locomotion (in one species), and a tail used for winter fat storage (in some species). They're probably substantially more strange than this as their ecology and behavior is poorly-known.

- Caenolestes condorensis
- Caenolestes sangay
- Caenolestes caniventer
- Caenolestes fuliginosus
- Lestoros inca
- Chilamblyopinus piceus
Darren (#8) brings up the possibility of a marsupial being a universal feature of crown mammals. Mike Keesey (#16) wonders if there were pouches on cynognathids, gorgonopsians, and sphenacodontids. Calling all speculative zoologists!
