Carbonate depositional systems in the Paleozoic geologic time represent fewer studies in paleoecological interactions than the siliciclastic systems. To evaluate this difference, the paleontology of the Middle Devonian Dundee Formation in Ohio has been explored. This geologic formation represents an important environment in the Michigan Basin of North America. Understanding biotic relationships such as mutualism, commensalism, parasitism and predation in an ecological community is important in unraveling the mystery of the fossil record. This research has contributed a large field collection which will be useful in documenting the fossil content of this unit for future workers. Rituparna Bose used new microscopic and imaging techniques in qualitatively analyzing the biotic interactions in small invertebrate shells. More importantly, she solved complex hypotheses in newly emerging problems in the field of geology and paleontology, such as the biodiversity crisis. Her study involved exploring the Devonian geology and paleontology of a geologic formation of a new unexplored quarry in Ohio, namely the Whitehouse Quarry in Lucas County, Ohio. She identified Devonian brachiopods to the genus level based on their morphology, and diagnosed paleoecological entities on host brachiopods and further measured episkeletobiont traces on hosts to understand the effects of environment and evolution on extinct species. Such studies have implications in predicting future biodiversity, ecosystem conservation and climate change. This research will also assist future workers to compare the ecology of brachiopod hosts of the Dundee Limestone with that of other Devonian brachiopods, from both carbonate and siliciclastic settings.

Fossil species appear to persist morphologically unchanged for long intervals of geologic time, punctuated by short bursts of rapid change as explained by the Ecological Evolutionary Units (EEUs). Here, morphological variation in Paleozoic atrypide morphology at the subfamily level (Atrypinae and Variatrypinae) from the Silurian and Devonian time intervals in the third Paleozoic EEU (~444-359 my) were investigated using relatively new techniques of quantitative modeling. The study explains how a group of closely related taxa in atrypide subfamilies exhibit morphological conservation through time in P3 EEU within the Eastern North America region.

Includes book reviews and abstracts.

The time has come. You are an Earth scientist. You’ve spent weeks, months, years working on this project – now is the time to pull it together for publication. You might be writing an undergraduate or graduate thesis, a research paper for a leading journal, a note for the newsletter of the local amateur scientific society, a book review or an abstract for a specialist geological conference. How do you make the transition from promising unpublished researcher to established academic author? Of course, the phrase ‘academic publishing’ covers a multitude of sins; monographs, research papers, book reviews, conference abstracts or whatever each requires a different approach. You have to decide what it is you are going to write and where to publish it. There are co-authors, supervisors of your degree, peer reviewers and editors to deal with on the way. But the only way to write like an academic is to write like an academic. . . where do you start? You could do much worse than start here. There are many books on how to write and be published aimed at research students and other aspiring academics. Many of these are readable, comprehensive and provide good advice. This book is composed of numerous short chapters on this subject, all directly relevant to one or more aspects of academic publishing and aimed particularly at the Earth scientists in the broadest sense. Geologists will be encouraged to use the book as much as a reference as a reader, ‘dipping in’ to the chapters that contain relevant tips, hints and comments to enable them to improve the paper that they are currently writing. The book is intended to be informative, readable and, above all, of practical application for all readers. In summary, the volume will be a readable compilation investigating many facets of academic publishing relevant to the Earth sciences. It will be of particular interest to postgraduate students, postdocs and new academics

This volume addresses major evolutionary changes that took place during the Ediacaran and the Paleozoic. These include discussions on the nature of Ediacaran ecosystems, as well as the ichnologic signature of evolutionary radiations, such as the Cambrian explosion and the Great Ordovician biodiversification event, the invasion of the land, and the end-Permian mass extinction. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.
