Also known as Lapparent site 33, Zarzaïtine

Where: Illizi, Algeria (27.8° N, 9.9° E: paleocoordinates 8.7° N, 6.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• "theropod" is from upper part of "Zarzaïtine inférieur"; dating of the assemblage from the upper part of the Lower Sandstone of the Lower Zarzaïtine is based upon vertebrate biostratigraphy. Jalil et al. (1995: Neues Jarhbuch für Geologie und Paläontologie, Monatshefte 1995:173-181) 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.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; sandstone

Size classes: macrofossils, mesofossils
