Overview
Characteristics
Didelphimorphs are small to medium-sized marsupials that grow to the size of a house cat. They tend to be semi-arboreal omnivores, although there are many exceptions. Most members of this order have long snouts, a narrow braincase, and a prominent sagittal crest. The dental formula is: 5.1.3.44.1.3.4 × 2 = 50 teeth. By mammalian standards, this is an unusually full jaw. The incisors are very small, the canines large, and the molars are tricuspid.

Both men encountered the language at the British settlement of Jamestown, Virginia, which Smith helped to found and where Strachey later served as its first secretary. Strachey's notes describe …

Opossums are frequently considered to be "living fossils", and as a result are often used to approximate the ancestral therian condition in comparative studies. However, this is inaccurate, as the oldest opossum fossils are from the early Miocene (roughly 20 million years old). The last common ancestor of all living opossums approximately dates to the Oligocene-Miocene boundary (23 million years ago) and is at most no older than Oligocene in age. Many extinct metatherians …
