Conodonts and Biostratigraphy of Upper Ordovician Strata along a Shelf to Basin Transect in Central Nevada
Conodonts representing 38 species of 26 genera have been identified in samples from Upper Ordovician rocks at three central Nevada localities. Ranges of these species and associated graptolites are used graphically to determine correlation of the strata considered with an evolving composite standard that includes information from Ordovician strata at more than 100 localities in North America. R...
متن کاملConodonts from the Aplington Formation of Northcentral Iowa
Conodonts comprising six species have been recovered from the Aplington Formation from five localities in northccntral Iowa. Although the Aplington conodont fauna is meager -it suggests a correlation with the Maple Mill Shale of southeastern Iowa. The Aplington Formation is vegarded as representing the youngest Devonian formation exposed in northcentral Iowa.
متن کاملMammal-like occlusion in conodonts
—Conodont element function and feeding mechanisms are of considerable paleobiological importance, yet many details remain poorly understood and speculative. Analysis based on morphology, physical juxtaposition, and patterns of surface damage and microwear on pairs of Pa elements from individuals of Idiognathodus indicates that these elements crushed food by rotational closure, which brought the...
متن کاملInflation with a stringy minimal length , reworked
In this paper we revisit the formulation of scalar field theories on de Sitter backgrounds subject to the generalized uncertainty principle (GUP). The GUP arises in several contexts in string theory, but is most readily thought of as resulting from using strings as effective probes of geometry, which suggests an uncertainty relation incorporating the string scale ls. After reviewing the string ...
متن کاملThe interrelationships of ‘complex’ conodonts (Vertebrata)
SYNOPSIS Little attention has been paid to the suprageneric classification for conodonts and existing schemes have been formulated without attention to homology, diagnosis and definition. We propose that cladisticsprovidesanappropriatemethodology to test existing schemesof classification and in which to explore the evolutionary relationships of conodonts. The development of a multielement taxon...
