Ekaltadeta is an extinct genus of giant marsupials related to modern rat-kangaroos. Ekaltadelta was present in what is today the Riversleigh formations in Northern Queensland from the Late Oligocene to the Miocene.[1][2]

They are hypothesized to have been either exclusively carnivorous, or omnivorous with a fondness for meat, based on their chewing teeth.[2] 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.[3] A few specimens actually did also have long predatory "fangs".

Fossils of the animals include two near complete skulls, and numerous upper and lower jaws.
