Where: Illizi, Algeria (27.8° N, 9.7° E: paleocoordinates 8.8° N, 6.2° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Lower Sandstone Member (Lower Zarzaïtine Formation), Late/Upper Triassic (237.0 - 201.4 Ma)

• Stratigraphic horizon of specimens is unknown, but they are from above "locality 5003" within the upper assemblage of the Lower Sandstone of the Lower Zarzaïtine Formation. Dating of the occurrences is based upon vertebrate biostratigraphy. Jalil et al. (1995) suggested a late Carnian age based upon putative overlap of Angistorhinus, Desmatosuchus and Paratypothorax, but none of this material appears diagnostic (Small 2002; Parker 2008; W. Parker pers. comm.). Given the very limited data, the assemblage is listed as Late Triassic here.
