While exploring the region around an archaeological site in the Peruvian Andes, researchers discovered a never-before-seen creature. The tiny, big-eyed marsupial — named Marmosa chachapoya — is a newly identified species of mouse opossum.
"We know very little about this species, including its natural history and distribution, and only one specimen has been collected so far," Silvia Pavan, a biologist at Cal Poly Humboldt who led the research expedition that discovered the creature, said in a statement.
