Brachiopods and molluscs of the Lower Permian Arcturus Group, Nevada and Utah by Thomas E Yancey( Book )

5 editions published in 1978 in English and held by 50 WorldCat member libraries worldwide

The Arcturus Group, early Permian, of eastern Nevada and western Utah contains the Riepe Spring Formation at the base, Riepetown Formation, Pequop Formation, and Loray Formation at the top, and ranges in thickness from less than 1000 meters to greater than 2000 meters. The base of the Arcturus Group is early Wolfcampian in the western and northern parts of the area, and middle Wolfcampian in the center of the depositional area. Deposition of sediments continued without significant interruption until the late Leonardian. The Leonardian-Guadalupian boundary occurs in the overlying Kaibab Formation. Normal salinity marine biotas are common throughout, and biotas representing hypersaline environments are present in the upper part of the Arcturus Group. Biotas representing hyposaline (brackish) and fresh-water environments are not recognized and are probably absent. Arcturus Group biotas are dominated by brachiopods and molluscs. Brachiopod diversity and abundances are low, except for the genera Squamaria, Costellarina, and Composita. The small productacean Costellarina is common in shallow-water molluscan-dominated biotas and is the most common brachiopod in the Arcturus. Brachiopods described as new are Costellarina kaasai, n. sp., Costellarina plasi, n. sp., Costellarina carlstroemi, n. sp., and Wilberrya fragilis, n. gen. and n. sp. The Costellarininae are transferred from the Strophalosiacea to the Productacea (Linoproductidae) on the basis of new information on the type genus Costellarina. Mollusc diversity and abundance are high in almost all biotas. Scaphopods, rostroconchs, and bivalves of the superfamilies Ctenodontacea, Nuculanacea, Arcacea, Pinnacea, and Ambonychiacea are described in this part of the study. Molluscan taxa designated as new are the bivalves, Quadratonnucula stella, n. sp., Polidevica arctura, n. sp., and Girtyana stellara, n. sp., and Meekopinna, n. gen

Recent sediments of Monterey Bay, California by Thomas E Yancey( Book )

6 editions published between 1968 and 1969 in English and held by 14 WorldCat member libraries worldwide

Monterey Bay, California's second largest bay, is the focus of drainage for three rivers draining an area in excess of 6,000 square miles in the adjacent Coast Ranges. The possibility that Monterey Bay has served as the outlet for drainage of the Central Valley during the late Tertiary has been suggested by many people, and the presence of the largest submarine canyon and the largest deep sea fan in California outside Monterey Bay is supporting evidence for this theory. The present work is primarily a description of the sediment cover in Monterey Bay and an analysis of the numerous variables controlling the distribution and accumulation of sediment within the bay.

Recent sediments of Monterey Bay : additional mineralogical data by Thomas E Yancey( Book )

3 editions published in 1971 in English and held by 14 WorldCat member libraries worldwide

The heavy mineralogy of the sand fraction for beach samples reported by Sayles (1966) and 10 new offshore samples from South Monterey Bay was determined optically. For each sample the percentage of the more diagnostic transparent minerals is plotted graphically in order of persistence: zircon, garnet, biotite, apatite, clinozoisite and epidote, lawsonite, green hornblende, oxy-horneblende, glaucophane, sphene, zoisite, augite, jadeite, hypersthene, enstatite, and tremolite and actinolite. Additional data on accessory transparent minerals, composite grains (rock fragments) and opaque minerals are listed with each graph. An updated bibliography is presented to include all new work on the geology and sediment of Monterey Bay. (Author)

Taphonomic signature as a function of environmental process : sedimentation and Taphofacies of shell concentration layers and "event beds", Holocene of Texas by D. J Davies( Book )

1 edition published in 1988 in English and held by 2 WorldCat member libraries worldwide

Standardized criteria for taphonomic processes, including dissolution, breakage, abrasion, size sorting, and shell orientation, were statistically correlated against environmental parameters representing shell source, depositional environment, and time since buried, for samples from a Texas microtidal inlet. Results from this taphofacies were then compared with accumulations from Texas bays and continental shelf. A model was developed for the 'event' deposition of shell beds for a clastic passive margin; it was evaluated in several modem and ancient deposits. Inlet sediments were differentiated by cluster analysis into eight classes based on their percent carbonate and percent shell gravel content. Boundaries between classes represent thresholds in physical processes. This classification scheme may be useful for field descriptions in many depositional and tectonic settings. Death assemblages were predominately whole and fragmental molluscan shells. Most shells shew the effects of physical taphonomic processes (shell breakage, rounding, surface abrasion, and size sorting). Major environments (estuary, bay, inlet, and continental shelf) are distinguished on the basis of shell taphonomic signature. A mixed fauna from the inlet showed patterns of dissolution, breakage, and abrasion differing significantly on shells derived from different habitats. Thus, a shell's habitat, rather than its final depositional environment, controlled most aspects of its taphonomic signature, except for shell orientation and size-frequency distribution. Statistical tests refuted that a high energy "event" (hurricane) imprints a unique taphonomic signature; it merely winnows and concentrates shell material. Whole shells more accurately reflect the proximate depositional environment; conversely, fragments portray more thoroughly the range of taphonomic processes producing a taphofacies. Most shell dissolution occurs at the sediment surface. Rates of shell production vs. dissolution indicate that shell material usually is preserved by rapid "event" burial; shell beds normally cannot form on the sediment surface. Such a quantified taphonomic approach is useful in paleoecological analysis, showing that "taphofacies" reflect not only the final depositional process, but also the taphonomic processes in the habitat of origin
Fusulinid paleontology and biostratigraphy of the Middle Permian (Guadalupian) strata of the Glass Mountains and Del Norte Mountains, west Texas by Zhendong Yang( Book )

1 edition published in 1993 in English and held by 2 WorldCat member libraries worldwide

Study of new collections of fusulinids from the Guadalupian Series in the Glass Mountains and Del Norte Mountains, west Texas, documents the presence of 44 species (in 10 genera) of fusulinids in the Middle Permian strata. Of these, 14 species are new, the genus Yangchienia Lee, 1933, is reported in North America for the first time, and one species of Rauserella Dunbar, 1944, two species of Lantschichites Toumanskaya, 1953, six species of Reichelina Erk, 1941, one species of Paradoxiella Skinner and Wilde, 1955, and 10 species of Parafusulina Dunbar and Skinner, 1931, are reported from this area for the first time. All species are documented with illustrations. This is the basis for a more detailed fusulinid zonation. The Guadalupian fusulinid-bearing sequence of strata in the Glass and Del Norte mountains area contains abundant fusulinid faunas and is as complete as that of the Guadalupe Mountains area. Diverse fusulinid faunas occur in the Road Canyon Formation and the Altuda Formation. The Mesogondolella serrata (conodont) first appearance datum lies between the Parafusulina boesei first appearance datum and the Parafusulina rothi first appearance datum, within the Road Canyon Formation. Nine fusulinid zones have been recognized. Of these zones, the Parafusulina durhami Zone is placed in the Leonardian Stage, the Parafusulina boesei Zone spans the boundary of the Leonardian and Guadalupian, and the Parafusulina rothi Zone, Parafusulina trumpyi Zone (Roadian Stage), Parafusulina sellardsi Zone, Parafusulina antimonioensis Zone (Wordian Stage), Polydiexodina shumardi Zone, Reichelina lamarensis Zone and Lantschichites splendens Zone (Capitanian Stage) are placed in the Guadalupian Series
The nature of information loss in the paleoecological reconstruction of benthic macrofaunal communities using faunal assemblages from the recent Texas coastal environment by George McDonald Staff( Book )

1 edition published in 1983 in English and held by 2 WorldCat member libraries worldwide

The living benthic communities and their death assemblages at two locations on the Texas coast were studied in detail to determine their taxonomic and structural variability so that the processes by which organisms are incorporated into the death assemblage might be understood as well as the extent to which the death assemblage provides information about the original community. The death assemblages were analyzed as paleocommunities to determine the minimum estimate of the amount of data loss and distortion that should be expected in the formation of a fossil assemblage from the original living community. Temporal variability in the living communities was attributable to seasonal and salinity changes in the physical environments at the study sites of Aransas River and Padre Island. The death assemblages did not reflect changes of the magnitude observed in the living communities at either location during the study. The major taphonomic processes that altered the original community data were; differential preservation of faunal, physical and biological addition and removal of fauna from the death assemblage, and predation. Time-averaging in concert with taphonomic processes, and bioturbation condensation of shells produced death assemblages that were very dissimilar to the original communities or the preservable components of the original communities. Taxonomic composition, diversity and equitability measures and trophic proportions were examined and the differences between the living community and the death assemblage data were quantified. Death assemblage analysis incorrectly indicated that the physically more stressed living community at Aransas River was more diverse and equitable than that of Padre Island. The impact of time averaging was greater at Aransas River because the death assemblage was a composite of the taxa from the living, low salinity community and the taxa from a previous high salinity community. The death assemblage, while making paleocommunity analysis uncertain, provides a modern ecological tool for learning about past enviromental extremes. Detailed study of a variety of benthic assemblages is needed to gain a graphic understanding of and to compensate for data loss and distortion in paleocommunity equivalents which will make paleocommunity reconstruction more accurate
