Is Marsupialia a subclass or an order? I think that is an order.

- It is absolutely not an order, Didelphimorphia c.s. are all separate orders. However, I think it might best be considered a "cohort" or so. Metatheria is the infraclass, and Marsupialia is that part of the infraclass which includes the real marsupials - but not deltatheroids and a few other extinct beasts. Ucucha 19:33, 6 Apr 2005 (UTC)
