Ovovivipary, you mean? Is assumed to be the intermediate stage. No positive
evidence whatsoever yet.

Do you mean non-therian? Otherwise you get a marsupial... but seriously,
most Mesozoic mammals (and the early groups of Eutheria that retained
epipubes) are usually thought to have reproduced like pouchless marsupials
today -- early birth, and the young are carried around in the fur. No
evidence known either for those outside Theria.

No idea.
