Smithian (Early Triassic) ammonoids from Crittenden Springs, Elko County, Nevada: taxonomy, biostratigraphy and biogeography.
2018
175 pages; International audience; We present a comprehensive monographic treatment of all currently known Smithian (Early Triassic) ammonoidtaxa from Crittenden Springs. Extensive collection efforts from numerous stratigraphically discontinuous, condensedoutcrops over a period spanning four decades has yielded a total of 60 taxa. This activity has also resulted in the recognitionof a new biostratigraphic succession unique to Crittenden Springs, consisting of 12 ammonoid intervals that normallyoccur within a typical ~1 m thick condensed outcrop. Ammonoids of early Smithian age are reported for the first timefrom this locality. Intraspecific variation of the more abundant taxa is documented …
