description Eretiscus tonnii Overview
Eretiscus tonnii is an extinct penguin species known from fossil deposits in Patagonia, Argentina. It forms part of the fossil penguin record of South America, where deposits preserve evidence of a long and diverse history of penguin evolution. The name refers to a paleontological taxon rather than a living species, and its anatomy and ecology should be discussed only in relation to the fossil material assigned to it. It is therefore of interest mainly to researchers studying fossil birds, South American geology, and penguin evolution.
