Where: Esmeralda County, Nevada (38.1° N, 118.0° W: paleocoordinates 11.8° N, 41.2° W)

When: Candelaria Formation, Dienerian (250.5 - 251.2 Ma)

• At the study site, the outcrop is not well exposed and covered by scree, except in a few shallow, seasonal stream channels, thus preventing the measurement of a stratigraphic section. Based on observations of in situ collected material, the bedding plane is nearly parallel to the local topography, so that all specimens are assumed to originate from a single horizon. A few external molds of ammonoids occur with the fishes (e.g., PIMUZ A/I 4730), but they are either indeterminable juveniles or poorly preserved. At the study sites of Ware et al. (2011), isolated bones (PIMUZ 35926) were found together with the late middle Dienerian (sensu Ware et al., 2015) A. lilangensis fauna, and it is probable that the fishes described herein are from the same horizon. The fishes clearly come from the lower Candelaria Formation, which is middle to late Dienerian in age (late Induan, early Early Triassic).
