Taxonomy
In his paper, Ameghino erected the family Cruschedulidae, however in his 1906 paper "Enumeracion de los Impennes Fosiles de Patagonia y de la Isla Seymour" he synonymized the family into Cladornithidae. When described Ameghino envisioned the genus and the family Cladornithidae as a whole to have represented a group of extinct "dry-land" penguins.[2] This was because the fossil, having been collected from an outcrop of the Deseado Formation, was thought to be similar to other penguin fossils Ameghino attributed to the same formation.[3] The Deseado Formation preserved a terrestrial environment, and thus the presence of penguins was considered highly unusual.
The placement of Cruschedula as a penguin was not challenged until 1946 by eminent
