Kurzfassung

Ein unvollständiges Skelett des AetosauriersParatypothorax andressi aus dem Petrified Forest National Park, Arizona, ist der erste Nachweis dieser Art in Nordamerika.Paratypothorax ist eine der wenigen Tetrapoden-Gattungen, die sowohl in Keuper-Schichten Deutschlands als auch in der Chinle Gruppe der westlichen USA auftreten.Paratypothorax hat jedoch geringen biochronologischen Wert, da die Gattung in Schichten wahrscheinlich vom späten Karn bis zum mittleren Nor vorkommt.

Abstract

A partial skeleton of the aetosaurParatypothorax andressi from Petrified Forest National Park, Arizona, is the first documentation of this species in North America.Paratypothorax is one of the few tetrapod taxa that occur in both the Keuper of Germany and the Chinle Group of the western United States, but it is of limited biochronological utility, because it occurs in strata that range in age from late Carnian to middle Norian.
