Book excerpt: Excerpt from Jurassic and Cretaceous Trigoniid Bivalves From West-Central Argentina Hinge teeth of the Trigoniidae are large and distinc tive, radiating from the beaks far into the interior of the shell. The dentition consists typically in the left valve of a strong median tooth and a weaker one on each side, and in the right valve of two main teeth dividing deep sockets which receive the teeth of the left valve; additional, smaller teeth may be present. The articulating surface of the teeth typically bear very well developed transverse ridges which are interpreted to have a crucial role in the alignment of the valves (stanley, Fossil evidence documents the origin of this kind of dentition early in the Mesozoic. Newell and Boyd (1975) suggested that dentition evolved in parallel in several lineages that are recognized by their external morphology. In coincidence with Poulton's (1979) opinion, however, this view is not tenable, as once established, this specialized dentition remained a conservative and stable feature, changing little from the early Mesozoic trigoniids to the living Neotrigonia.

Download or read book Jurassic and Cretaceous Trigoniid Bivalves from West-central Argentina written by Héctor A. Leanza and published by Paleontological Research Inst. This book was released on 1993 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes 73 species and 1 subspecies of precisely dated Trigoniidae from the Lower Jurassic (Liassic) to the Upper Cretaceous (Maastrichtian) of western central Argentina. These are classified into 14 subfamilies as follows: Minetrigoniinae, Trigoniinae, Neuquenitrigoniinae, n. subfam., Frenguelliellinae (emend.), Myophorellinae, Vaugoniinae, Steinmanellinae, Anditrigoniinae, n. subfam., Megatrigoniinae, Buchotrigoniinae, n. subfam., Pterotrigoniinae, Laevitrigoniinae, Austrotrigoniinae and Nototrigoniinae. The Frenguelliellinae are reinterpreted to range in age from the Triassic to the Middle Jurassic (Bajocian), and include only the genera Frenguelliella and Kumatrigonia. Neuquenitrigoniinae, n.subfam., include the very specialized Middle Jurassic genus Nequenitrigonia, which shows a transversely costate flank and escutcheon, characteristics that are absent in Trigoniinae s.s. Anditrigoniinae, n. subfam., is erected to group the Middle Jurassic to Lower Cretaceous genera and subgenera Eoanditrigonia, n. subgen., Anditrigonia, Paranditrigonia, Antutrigonia, Virgotrigonia, and Lambertrigonia, n. gen., which are characterized by an smooth area in early representatives, or by transverse or radial ornamentation, or a combination of both, and a poor to well developed marginal carina. The Buchotrigoniinae, n. subfam. include the very specialized Lower Cretacious genera Buchotrigonia and Syrotrigonia, which are characterized by a tripartite development of oblique, subconcentric and subvertical costae on the flank. The treated genera are twenty one, including: Groeberella, n. gen. (type species: Myophoria neuquensis Groeber, 1924), Trigonia, Grenguelliella, Jaworskiella, Myophorella, Scaphotrigonia, Scaphorella, Neuquenitrigonia, Vaugonia, Andivaugonia, n. gen. (type species: Trigonia keideli Weaver, 1931). The Upper Jurassic and Cretaceous genus Pterotrigonia is divided into the subgenera Pterotrigonia sensu stricto, Scabrotrigonia, Rinetrigonia, and Notoscabrotrigonia. Ten new species and one new species are established, as follows: Frenguelliella poultoni (Liassic); Trigonia losadai, Trigonia levyi, Frenguelliella perezreyesi, and Scaphorella camachoi (Middle Jurassic); Myophorella (Myophorella) schulzi, Myophorella (Haidaia) eleguetai, Pterotrigonia (Notoscabrotrigonia) coheni, and Anditrigonia (A.) exima tesselicaudata (Upper Jurassic); Rutritrigonia kauffmani and Syrotrigonia brocardoi (Lower Cretaceous). Comments on the Family Trigoniidae, as well as taxonomic considerations, stratigraphic occurrence, and facies relationships of the described species are presented. With the new taxonomy proposed here, the trigoniids have a much greater temporal resolution than previously thought, especially at the species level.

Available in PDF, EPUB and Kindle. Book excerpt: "Displaced or tectonostratigraphic terranes comprise a huge portion of real estate in the North American Cordillera. Terranes are discrete, fault-bound blocks of regional extent, with rocks and fossils that differ to a great extent from those of adjacent blocks. The allochthonous nature of most terranes, relative to adjacent craton, is well established. When mapped, they resemble a collage of mixed rock types, tectonic styles, metamorphism, and volcanic origins--each part resembling the pieces of a puzzle. Terrane studies remain integral to understanding the geological evolution of western North America. Since the initiation of the concept summarized in 1979 by the late David L. Jones, the significance of fossils and stratigraphy has been key to solving the puzzle. Chapters of this book written by experts in their field, provide a sense of the diversity of approaches in paleontology and stratigraphy. Contributions span geologic time from the Precambrian (Vendian) to Cretaceous and address over 20 Cordilleran terranes."--Publisher's website.

Available in PDF, EPUB and Kindle. Book excerpt: The Neuquen Basin of northern Patagonia provides an excellent case study in basin analysis and sequence stratigraphy. The basin is one of the largest petroleum provinces in South America and includes a dramatic record of relative sea level changes as well as a unique and globally important palaeontological record. Understanding this region is also central to unravelling the history of the Andes. The latest developments in the study of the area have been combined in this volume to give an integrated series of case studies that document the structural, igneous, sedimentological and palaeontological history of the region from the Triassic to the Recent. This publication provides an introduction into this fascinating region as well as a resource that includes the most complete and up-to-date studies of the area.
