No it is
Arcucci, A. B., 1998, New information about dinosaur precursors from the
Triassic Los Chanares Fauna, La Rioja, Argentina: In: Journal of African Earth
Sciences, v. 27, n. 1A July 1998, Special Abstracts Issue, Gondwana 10: Event
Stratigraphy of Gondwana, p. 9-10.
Basically the material is now in Argentina and has been prepared better and
they have found that there were mistakes in the original description. The type
specimen consist of a well-preserved skull (braincase and lateral temporal area
articulated with the posterior part of the mandible, and maxilla with teeth)
and post cranial remains, including the complete and articulated presacral
series, shoulder girdle and both humeri. The slab still needs to be prepared
(as of 1998) but the similarities between the tibia and dorsal vertebrae
strongly suggests that Lewisuchus and Pseudolagosuchus are the same.
