description Juramaia sinensis Overview
Juramaia sinensis is an extinct, small-bodied mammal known from a fossil discovered in Liaoning Province, China, and described in 2011. The specimen was assigned to Eutheria, the lineage that includes placental mammals and their extinct relatives, and dated to roughly 160 million years ago in the Late Jurassic. Its classification and geological age have subsequently been debated, so its status as the earliest known eutherian is not universally accepted.
