Discosauriscus austriacus (Makowsky 1876; Klembara 1997, Klembara and Bartik 1999; Early Permian, 250 mya) is known from several hundred specimens from larvae to subadult stages. It nests between Kotlassia and Seymouria in the large reptile tree. The palate was closed in adults. Manual and pedal digits 4 had five phalanges. The ilium had a robust posterior process and a small anterior process.

The morphology of the atlas-axis complex is similar to that in Seymouria sanjuanensis. The neural arches start to swell slightly in specimens of late larval stage; they are completely swollen immediately after metamorphosis. The six caudal ribs should have been lateral in orientatiion, pointing posteriorly, rather than ventrally as Klembara and Bartik illustrated them.
