Deltatheridium is a genus of Deltatheridiidae that lived in the Gobi Desert during the Campanian around 80 million years ago. It makes a brief appearance in the documentary Dinosaur Planet.
A Deltatheridium is seen climbing a tree near the nesting Velociraptor, White Tip. Caught off guard, White Tip moved in to kill it, before hearing another Velociraptor, Broken Hand, raiding her nest.
