Cladornis is an extinct genus of bird from the early Oligocene of Argentina. Known from a single partial tarsometatarsus, its taxonomic placement is uncertain.[1] It has been variously described as some kind of terrestrial penguin, a pelecaniform, and a "very large and extremely weird land bird".[1][2] The shaft the tarsometatarsus of Cladornis was very flat and short, and the distal head suggests strong development of the toes.[1]
