Cenozoic fossil Naticidae (Mollusca: Gastropoda) in Japan by Ryuichi Majima( Book )

2 editions published in 1989 in English and held by 46 WorldCat member libraries worldwide

The gastropod family Naticidae consists of carnivorous prosobranches that occur commonly in worldwide Cenozoic marine strata and in modern seas. Important taxonomic characters are umbilical morphology, shell-surface sculpture, opercular morphology and radular dentition. Umbilical morphology is the most useful for discriminating species, whereas the other characters are more useful for supraspecific classification. A total of 47 species and subspecies belonging to 19 genera in four subfamilies are treated here. Among them, Euspira marincovichi and Glossaulax didyma dainichiensis are described as new taxa. Naticids occurring only in the Holocene Japanese fauna are not included here. The Japanese Neogene and Early Quaternary naticids are classifiable into three paleoclimatic preference types: warm-water, cold-water, and broad temperature tolerance. These types are defined on the basis of paleogeographic distributions, associated molluscs, and the geographic distributions of extant naticid taxa. Paleogeographic distributions of the warm- and cold-water types clearly reveal Neogene and early Quaternary fluctuations of the biogeographic boundary between southern and northern faunal types in Japan. Many Japanese naticid species have evolved or become extinct in response to Cenozoic climatic fluctuations and several species are grouped into five lineages, based upon a combinations of shell morphology and stratigraphic distribution: the Glossaulax hyugensis - G. nodai - G. hagenoshitensis lineage (lower Pliocene - lower Pleistocene), the Glossaulax didyma coticazae - G. didyma didyma - G. didyma dainichiensis - g. vesicalis lineage (lower middle Miocene - Holocene), the Euspira meisensis - E. marincovichi - E. mitsuganoensis lineage (Oligocene - middle middle Miocene), the Euspira pallida - E. pila - E. yokoyamai lineage (lower Pliocene - Holocene), and the Cryptonatica clausa - C. ichishiana - C. janthostoma - C. andoi lineage (lower middle Miocene - Holocene). The three Japanese taxa, Euspira meisensis, Polinices didymoides, and Glossaulax didymoides, and Glossaulax didyma coticazae, are closely similar to Euspira hotsoni, Polinices hornii, and Glossaulax reclusiana, respectively, of western North America and are considered to be descendants of migrants form the northeastern Pacific

Frasnian (Upper Devonian) rugose corals from the Lime Creek and Shell Rock formations of Iowa by James E Sorauf( Book )

2 editions published in 1998 in English and held by 46 WorldCat member libraries worldwide

Rugose corals from Frasnian Lime Creek ("Hackberry") and Shell Rock strata are known laregly from the works of Fenton and Fenton (1924) and Belanksi (1927, 1928), each of which described outcrop stratigraphy and major parts of the fauna. The Shell Rock Formation includes three members, two of which contain rugosans, the basal Mason City and the uppermost, or Nora Member. The overlying Lime Creek Formation contains the Juniper Hill Member, lacking corals, overlain by the very fossiliferous Cerro Gordo Member, source of much of the famous "Hackberry" coral fauna described by Fenton and Fenton in 1924. The uppermost, Owen Member, also contains abundant Rugosa. Considerable diversity is present in these Frsnian corals. The Family Endophyllidae is represented by Iowaphyllum johanni. Kyphophyllidae include the genera Tabulophyllum, Tarphyphyllum, and Smithiphyllum. Species of Tabulophyllum are especially abundant in both the Lime Creek and Shell Rock faunas. The type species. T. rectum, occurs only within the Cerro Gordo Member, with its synonyms, T. regulare and T. erraticum. Cerro Gordo beds also contain a small ovate form, T. ehlersi and the more robust T. rotundum, each greatly resembling T. recum as juveniles. The Cerro Gordo also contains the larger species Tabulophyllum robustum, a large ovate form, T. ellipticum, and additionally, the largest of the Cerro Gordo solitary corals, T. ponderosum. The overlying Owen Member contains large Tabulophyllum species, with T. longum, the most numerous, T. magnum, often bilaterally symmetrical, and T. expansum the largest of the solitary Lime Creek species

Review of selected North American mitrate stylophorans (Homalozoa: Echinodermata) by Ronald L Parsley( Book )

2 editions published in 1991 in English and held by 45 WorldCat member libraries worldwide

This paper reviews most of the North American mitrate stylophoran genera and species that are assigned to two suborders, the Anomalocystitida and the Peltocystida. The Anomalocystitida is herein divided into two long-ranging families, the Anomalocystitidae and the Placocystitidae. The Anomalocysitidae contains mostly North American species (Middle Ordovician-Early Devonian) that are characterized by the proximal carapace margin having three plates, and only very rarely a placocystitid plate. North American species include, within the new subfamily Anomalocystitinae, Willmanocystis denticulatus Kolata and Jollie, 1982 (Middle Ordovician), Kieroystis insertus, n. gen. and sp. (Middle Ordovician), Anomalocystites cornutus Hall, 1859 [=A. disparilis Hall, 1859], (Early Devonian); and within the subfamily Enoplourinae, Enoploura punctata Bassler, 1932 (Middle Ordovician), Enoploura balanoides (Meek, 1872 [=E. crustacea (Haeckel, 1896) = E. wetherbyi Caster, 1952 = E. meeki Caster, 1952] and Enoploura popei Caster, 1952 (Late Orddovician). Species assignable to the Placocystitidae are found in North America, Europe and Australia. They are characterized by the proximal carapace having only two plates in contact with the aulacophore, the MA plate consistently excluded, and the placocystitid plate rarely missing. North American forms discussed herein include, within the subfamily Placocystitinae, Ateleocystites huxleyi Billings, 1858 (Middle Ordovician), and Kopficystis kirkfieldi, n. gen. and sp. (Middle Ordovician). It seems likely that the Southern Hemisphere subfamily Allanicytidiinae branched off from the Peltocystida, the kirkocystid Anatiferocystis spinosa Ubaghs, 1979 [= Kirkocystis papillata (Bassler, 1932)] from the Middle Ordovician of Oklahoma, is represented in Bohemia as well. This genus has a greatly reduced number of plates. The disposition and growth of these plates are discussed herein. The feeding of mitrates are seen to be different than previously reported. In mitrates, the aulacophore faced into the prevailing current, convex upward, and food was conveyed to the food groove under the dorsally-fused cover plates through the arcuate to chevron-shaped openings between the overlapping set of cover plate pairs. The width of these openings of was controlled by the degree of distal aulacophore convexity. Previous representations of feeding figured the distal aulacophore concavely curved over the proximal aulacophore and proximal theca. I see this as a closing mechanism, used under extreme conditions, that resulted in jamming together of the overlapping fused cover plate pairs (the configuration commonly preserved in the fossil record). Origin of the Anomalocystitida derives from Reticulocarpos-like cornutans. It is suggested that the distal marginal plate elements of the theca in the cornute ancestral stock have been lost. Only M1-M4 thecal marginals are homologous between cornutes and anomalocystitids

Stratigraphy and correlation for the ancient Gulf of California and Baja California Peninsula, Mexico by Ana Luisa Carreño( Book )

7 editions published in 2007 in English and held by 44 WorldCat member libraries worldwide

This paper presents the first comprehensive stratigraphic correlation charts for both th eBaja California peninsula and the Gulf of California area since Durham and Allison (1960). Forty-five columns show stratigraphic or lithologic units for San Diego, California through western Baja California, Mexico, and the Salton Trough of California to the Islas Tres Marías, Nayarit, Mexico. Correlations are based on published and unpublished stratigraphic, paleontologic and radiometric data. The columns refined the chronostratigraphic context for interpreting the geologic history of the ancient Gulf of California and a series of embayments along the western Baja California peninsula. We summarize upper Mesozoic to Auaternary stratigraphy, but emphasize Tertiary marine units, including those that were described formally without full locality and stratigraphic data, and unnamed lithologic units that need further study. The lack of detailed geologic mappings over large parts of the area accounts for much of the variation in formal stratigraphic nomenclature. Periodic reviews are needed to improve age data and constrain events in this structurally complex area, which includes the Basin and Range Province, the San Andreas Fault system, the East Pacific Rise, the Gulf Extensional Province, the Puertecitos Volcanic Province, and the California Continental Borderland. Selected references to paleontologic and radiometric data are listed in Appendix 1. They document the earliest seawater in the northern Gulf of California in late Middle or early Late Miocene time, multiple marine incursions into the Salton Trough of California, and more refined chronostratigraphic ranges for such problematic units as the Imperial Formation, Comondú Formation, Salada Formation and El Cien Formation
