Mcdonaldocnus is an extinct genus of nothrotheriid ground sloths that lived during the Middle Miocene and Early Pliocene of what is now Bolivia and Argentina . It was originally placed in the genus Xyophorus but was subsequently recognized as a distinct genus by Gaudin and colleagues in 2022.[1] The authors reassigned the material of "Xyophorus" bondesioi, Xyophorus villarroeli and Xyophorus sp. to Mcdonaldocnus.[2][3][4] Fossils of Mcdonaldocnus have been found in the Cerro Azul Formation of Argentina.[5]
Etymology
The genus name, Mcdonaldocnus, is composed of the prefix Mcdonald-, which honors the retired U.S. Bureau of Land Management scientist Dr. H. Gregory McDonald, a notable sloth specialist, and the greek suffix -ocnus, meaning "hesitating or inactive", which is commonly used to name extinct sloths. The species name, Mcdonaldocnus bondesioi, honors the paleontologist Pedro Bondesio[1]
