The Ekaltadeta is an extinct genus of giant marsupials related to modern rat-kangaroos. They are hypothesized to have been either predatory, or omnivorous with a fondness for meat, based on their chewing teeth. This conclusion is based mainly on the size and shape of a large buzz-saw-shaped cheek-tooth, the adult third premolar, which is common to all Ekaltadeta. A few species actually did also have long predatory "fangs". Fossils of the animals include two near complete skulls, and numerous upper and lower jaws.
