What is "cinizasaurus"

"Cinizasaurus" is an informal name for fossilized remains from the Late Triassic of New Mexico that were initially interpreted as belonging to a theropod dinosaur. The remains, NMMNH P-18400, consist of a tibia, vertebrae, and fragments, and came from the ? late Carnian-age Upper Triassic Bluewater Creek Member of the Chinle Formation, near Fort Wingate. Andrew Heckert, in his unpublished thesis, proposed the name "Cinizasaurus hunti" for the specimen, but the name was never adopted, and was first referred to in the scientific literature in a 2007 redescription of Late Triassic North American material thought to belong to dinosaurs (Nesbitt, Irmis, and Parker, 2007). In the redescription, the authors could only assign the material to Archosauriformes.
