Real-world information
Juramaia sinensis is one of the earliest known eutherians, or mammals more closely related to placental mammals than marsupials. It lived during the Late Jurassic in northeastern China and shared its habitat with early ancestors of birds, including Anchiornis and Xiaotingia. Juramaia's forelimbs were adapted for climbing, leading some to speculate that early eutherians may have been arboreal.
