Fona (meaning "the origin") is an extinct genus of thescelosaurine thescelosaurid ornithischian dinosaurs from the 'mid'-Cretaceous Cedar Mountain Formation (Mussentuchit Member) of Utah, United States. The genus contains a single species, F. herzogae, known from several partial skeletons and skulls. Based on anatomical similarities to the closely related and similarly aged Oryctodromeus, Fona was likely a semi-fossorial animal, likely spending a significant amount of time in underground burrows. It also represents the oldest known definitive thescelosaurine.[1]
