Vonhuenia  Vonhuenia is an extinct genus of basal archosauriform from the Early Triassic of Russia. Fossils have been found along the Vetluga River that are Induan in age, making "Vonhuenia" one of the earliest archosauriforms. The type species "V. friedrichi", named in 1992, is based on material that was misassigned to the genus "Chasmatosuchus" by Ochev (1978). Although originally classified as a proterosuchid, a 2016 cladistic analysis recovered it as a non-eucrocopodan archosauriform of uncertain position. "Vonhuenia" was a small archosauriform that lived alongside amphibians like "Tupilakosaurus" and "Luzocephalus", small reptiles like "Phaanthosaurus", and the large-bodied dicynodont "Lystrosaurus" in the earliest Triassic.
