Decided to axe Category:Placentals. I made this decision when I realized that: This is still how things are generally seen, even though recent advances in molecular biology have made it possible to define taxonomical divisions into the structure of clades we can study today.
 * Dictionary.com doesn't even have an animal-family-related entry for "placental."
 * Placental mammals are so common as to seem "default," such that we speak of each familiar family division of placentals as a kind of "mammal" while considering marsupials as just another family-level division of "mammal."
