East central North America climates during marine isotope stages 3-5

The discovery of a new locality yielding giant Guadalupian (Lower Permian) fusulinids in east-central Alaska extends the range of these forms much farther north than previously known, and into a tectonostratigraphic terrane from which they previously had not been reported. The number of areas from which giant parafusulinids are known in North America is thus raised to eight. Three of these localities are in rocks that previously had been referred to the allochthonous McCloud belt arc, and one, West Texas, is known to have been part of Paleozoic North America. Comparison of species from all areas suggests that there are two closely related species groups: one represented in Texas and Coahuila, and the other represented in Sonora, northern California, northeastern Washington, southern and northern British Columbia, Alaska, and apparently in Texas. These groups may differ because they are of slightly different ages or because interchange between the faunas of Texas–Coahuila area and the other regions was somewhat inhibited during the Early Permian.

A New Species

The late Mississippian ammonoid family Delepinoceratidae is comprised of the genera Platygoniatites and Delepinoceras, and is considered one of the more biostratigraphically significant families for lower Namurian correlation (Manger et al., 1985). Platygoniatites, the earliest member, is known from eastern and southern Europe (Ruzhencev and Bogoslovskaya, 1971; Wagner-Gentis, 1963, 1980) and North Africa (Lemosquet et al., 1985). Despite its wide distribution, Platygoniatites is generally a rare member (with the exception of the southern Ural Mountains) of latest Visean and earliest Namurian faunas. It has never been reported previously from North America, though thousands of ammonoids have been collected here from age equivalent beds. The discovery of a new species of the genus in the late Mississippian faunas of east-central Nevada provides new data for precise correlation of the ammonoid zonations of Gordon (1970) to the type Namurian and indicates a need for revision of the current correlations between the southern Urals and northwestern Europe.
