Book Description
The Salinas Valley region contains the type areas of the Monterey Shale and the Santa Margarita and Pancho Rico Formations as well as the type areas of the Relizian and Luisian Stages of Kleinpell. Only in and very near the Adelaida 7-1/2-minute quadrangle do strata representing these three marine units crop out in close proximity. In addition, beds that contain fossil marine mollusks of Paleocene age crop out in the quadrangle. Of particular significance in Coast Range stratigraphy are the wide range in Tertiary age fossils found in the Adelaida quadrangle and the geographic position of the quadrangle between the type areas of the Relizian and Luisian Stages of Kleinpell.

Book Description
TMS Special Publication 6. This TMS Special Publication comprises a collection of 23 papers with an international authorship reflecting on landmarks in the history and development of Foraminiferal micropalaeontology. The volume is prefaced by an introductory overview that provides a brief and selected historical setting, as well as the intended aims of the book. Selected developments in Foraminiferal studies from a global perspective are presented from the time of Alcide d'Orbigny and the founding of the Paris MNHN collections in the mid-nineteenth century to the use of foraminifera in industry, other museum collections, palaeoceanography and environmental studies, regional studies from the Southern Hemisphere and the rise and fall of significant research schools. The book concludes with a chapter on the modelling of foraminifera. Landmarks in Foraminiferal Micropalaeontology: History and Development will be of particular interest to micropalaeontologists, other Earth scientists, historians of science, museum curators and the general reader with an interest in science.

Book Description
While several papers exist on the small scale spatial distribution of living foraminifera, almost no work exists on the small scale spatial distribution of fossils. The present study took 24 (5 ml) replicates 10 cm apart along one bed of the Monterey Formation in California.The mean density for all replicates is 6084.96 with a standard deviation of 8776.95. Both inspection and a cluster analysis of the data indicate replicates 20-24 have a much higher density and different rank order of abundance than replicates 1-19. The mean density for the total of all species in replicates 1-19 is 2387.47 with a standard deviation of 1175.58. For replicates 20-24 the mean density is 20135.40 with a standard deviation of 11181.40. The spatial variability is so great that four replicates (more than commonly taken) would only allow us to be 95% confident that we are within 50% of the true mean. Because age determination is based on presence of particular taxa rather than on densities, stratigraphic assignment would still be possible.The three species dominating the 1-19 group make up from 86% to 99% of the fauna. The three species dominating the 20-24 group make up from 77% to 85% of the fauna. Two of these are also dominant in the 1-19 group, but the most dominant species in the 20-24 group constitutes only
