About Alphadon:

As is the case with many of the early mammals of the Mesozoic Era, Alphadon is known mainly by its teeth, which peg it as one of the earliest marsupials (the non-placental mammals represented today by Australian kangaroos and koala bears). Appearance-wise, Alphadon probably resembled a small opossum, and despite its tiny size (only about three-quarters of a pound soaking wet) it was still one of the largest mammals of its day. Befitting its small stature, it's believed that Alphadon spent most of its time in trees, well out of the way of the stomping tyrannosaurs and titanosaurs of the late Cretaceous period.
