Some later studies proposed that it was an early crocodylomorph or "sphenosuchian" like Saltoposuchus, another pseudosuchian from the middle Stubensandstein of Baden-Württemberg.
To this division belong the Myophoria beds (M. Raibliana) with galena in places; the Estheria beds (E. laxilesta); the Schelfsandstein, used as a building-stone; the Lehrherg and Berg-gyps beds; Semionotus beds (S. Bergen) with building-stone of Coburg; and the Burgand Stubensandstein.
The fragmentary and poorly preserved skeleton of Procompsognathus was found in the Middle Stubensandstein member of the Löwenstein Formation at the Weiße Steinbruch, the quarry of Albert Burrer on the northern slopes of the Stromberg region near Pfaffenheim in Württemberg, Germany.
