One of the animal designs for the Surviving Dinosaurs project, done back in early 2018. This animal was the apex predator of Australia, usurping the native dinosaurian hunters during the continent's aridification (the title is not its actual name), when their lower metabolisms made surviving on far scanter prey more easy. It's a giant baurusuchian convergently resembling the ancient rauisuchians of the Triassic, including having a facultatively bipedal stance.
