Abstract
The skeleton of the archosauriform Turfanosuchus dabanensis Young, 1973 is redescribed on the basis of further preparation. For the first time a set o f derived features is recognised for diagnosing this species. Re-examinatio n of the specimen reveals the presence of palatal teeth in the pterygoid; t he ventral entrance of the internal carotid arteries posterior to the basip terygoid processes; the calcaneal tuber shaft taller than broad; the absenc e of flaring of the distal end of the calcaneal tuber; the calcaneal tuber shaft convex laterally and concave medially; and the tibial facet on the as tragalus simply concave. These features are strongly indicative that T. dab anensis is not a suchian and not even a crurotarsan, which sharply contrast s with its recently-proposed basal suchian status.
