The type species V. friedrichi, named in 1992, is based on material that was misassigned to the genus Chasmatosuchus by Ochev (1978).[2] Although originally classified as a proterosuchid, a 2016 cladistic analysis by Ezcurra et al. recovered it as a non-eucrocopodan archosauriform of uncertain position.[3] However, a 2023 cladistic analysis of the Proterosuchidae, again by Ezcurra et al., again recovered Vonhuenia as a proterosuchid, specifically as a basal member of the subfamily Chasmatosuchinae. The earliest known proterosuchid and archosauromorph, Archosaurus, is also placed in Chasmatosuchinae but is thought to be more derived than Vonhuenia, suggesting that the ancestors of Vonhuenia diverged from other chasmatosuchines during the Late Permian.[4]
