Dora M. Gallegos Valery V. Chernykh Walter S. Snyder Bruce R. Wardlaw 2015 <p>The lower Part of the Garden Valley Formation yields two distinct conodont faunas. One of late Asselian age dominated by M<i>esogondolella</i> and <i>Streptognathodus</i> and one of Artinskian age dominated by <i>Sweetognathus</i> with <i>Mesogondolella</i>. The Asselian fauna contains the same species as those found in the type area of the Asselian in the southern Urals including <i>Mesogondolella dentiseparata</i>, described for the first time outside of the Urals. Apparatuses for <i>Sweetognathus whitei</i>, <i>Diplognathodus stevensi</i>, and I<i>dioprioniodus</i> sp. are described. The Garden Valley Formation represents a marine pro-delta basin and platform, and marine and shore fan delta complex deposition. The fan-delta complex was most likely deposited from late Artinskian to lateWordian. The Garden Valley Formation records tremendous swings in depositional setting from shallow-water to basin to shore.</p> application/pdf en Micropaleontology Press Early Permian conodont fauna and stratigraphy of the Garden Valley Formation, Eureka County, Nevada article
