Quercylurus

Quercylurus major is a nimravid carnivoran, or "false sabre-tooth," from the early Oligocene of France. Its fossils are found from Early Oligocene strata in Quercy. Q. major. was possibly the largest nimravid ever known, as its fossils suggest it was similar in size to the modern-day brown bear and was scansorial.[1] It was very muscular, walked on plantigrade (flat-footed). So far, there is only one described species within this genus - Q. major.
