Hilalia is an extinct genus of condylarth that lived during the Eocene. Fossils of Hilalia have been found at Uzunçarsidere Formation in Turkey.[1] It was the last surviving genus of Pleuraspidotheriids, which were previously thought to have gone extinct during the Late Palaeocene.[2]

Paleoecology
During the Eocene, Turkey is believed to have been an island ecosystem, harboring many taxa that had gone extinct on mainland areas earlier.[3]
Living alongside Hilalia were embrithopods and various metatherians, such as the predatory Anatoliadelphys.[4][5]
