Not long ago, а new raptor-like dinosaur from some 70 million years ago that ate fish and behaved like modern herons has been unearthed from southern Patagonia. The new species, which has been named Kank australis, was identified based on the discovery of fossil remains including teeth, vertebrae, and toe bones.

K. australis is an unenlagiid, a family of small-to-medium sized theropod dinosaurs whose members have been unearthed from Late Cretaceous deposits in South America, Antarctica, Australia, and Madagascar. Based on comparison with another unenlagiid, Neuquenraptor argentinus, which lived in northern Patagonia 90 million years ago, researchers believe adults of the new species likely grew up to some 2.5–3 meters long.
