Book Description
The authors have done an outstanding job of compiling decades of data collected by their own field reconnaissance and other geoscientists... This represents a significant contribution to the understanding of the development of the Florida carbonate platform, and it will assist other disciplines as they strive for better understanding of our groundwater resources, aquifer characterizations, paleoenvironmental interpretations, and historical/educational geology programs. Walt Schmidt, Florida State Geologist & Chief, Florida Geological Survey, USA (praise for the first edition) Painting a complete picture of the history of the Everglades, Ancient Seas of Southern Florida: The Geology and Paleontology of the Everglades Region, Second Edition provides an overview of the geology, paleontology, and paleoceanography of the region. It emphasizes the upper 300m of the geologic framework of the area and gives insight into the local stratigraphy, geomorphology, lithology, and historical geology. Designed to be a field guide as well as a reference, the book is illustrated in full color with brand new photographs of exposed geologic sections, stratotype localities, collection sites, and details of interesting fossil beds. In this book, the authors illustrate almost 800 of the most important and diagnostic stratigraphic index fossils found in these beds, including over 50 species of corals and almost 700 species of mollusks, along with echinoderms, crustaceans, echinoids, petrified wood, and aquatic vertebrates. A new edition of The Geology of the Everglades and Adjacent Areas, it contains larger images of fossil shells, corals, and echinoderms and includes new updated geological data and concepts, as well as an expanded iconography of stratigraphic index fossils. Based on the data gleaned from these fossils, it also offers a series of geomorphological visualizations, showing the possible appearances of the Florida Peninsula during the times when it was covered by tropical seas, from the Oligocene to the late Pleistocene. This second edition provides a new perspective on both the historical geology of southern Florida and the evolution of one of America’s most beautiful natural treasures, the Everglades.

Pages : 250
Book Description
Painting a complete picture of the history of the Everglades, The Geology of the Everglades and Adjacent Areas brings together theperspectives of various geoscientists to provides an overview of the geology, paleontology, and paleoceanography of the Everglades region. It emphasizes the upper 300 m of the geologic framework of the area and gives insight into the local stratigraphy, geomorphology, lithology, and historical geology. Building upon the geologic nomenclature and stratigraphic sequences set down by the Florida Geological Survey, the book includes redefinitions of some previously poorly known formations, the chronological fine-tuning of other poorly known units, and the description of 7 new members. Designed to be a field guide as well as a reference, the book is illustrated with photographs of exposed geologic sections, stratotype localities, collection sites, and details of interesting fossil beds. It contains 124 full-page illustrations with 69 black and white figures, 43 black and white plates of index fossils, and 12 full color plates of simulated space shuttle images of Florida’s ancient seas and coastlines. This text is accompanied by downloadable resources that feature animated maps along with a Power Point presentation of simulated space shuttle imagery of Eocene-to-Holocene Florida. The book is arranged by geologic time, ranging from the late Eocene, Oligocene, Miocene, Pliocene, and Pleistocene to the Holocene. The authors place lithostratigraphic descriptions of the geologic formations and members into this chronological framework, along with the paleogeography of the seas and lakes within which they were deposited. They also emphasize biostratigraphy with over 1000 index fossils listed and over 400 illustrated. The book brings together information previously spread through innumerable publications, saving you the time and effort it would take to assemble and cross-reference multiple sources.

Category : Nature
Languages : en
Pages : 414
Book Description
A Science Friday Best Science Book of the Year A Kirkus Reviews Best Nonfiction Book of the Year A Library Journal Best Science and Technology Book of the Year A Tampa Bay Times Best Book of the Year A stunning history of seashells and the animals that make them that "will have you marveling at nature…Barnett’s account remarkably spirals out, appropriately, to become a much larger story about the sea, about global history and about environmental crises and preservation" (John Williams, New York Times Book Review). Seashells have been the most coveted and collected of nature’s creations since the dawn of humanity. They were money before coins, jewelry before gems, art before canvas. In The Sound of the Sea, acclaimed environmental author Cynthia Barnett blends cultural history and science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. Spiraling out from the great cities of shell that once rose in North America to the warming waters of the Maldives and the slave castles of Ghana, Barnett has created an unforgettable history of our world through an examination of the unassuming seashell. She begins with their childhood wonder, unwinds surprising histories like the origin of Shell Oil as a family business importing exotic shells, and charts what shells and the soft animals that build them are telling scientists about our warming, acidifying seas. From the eerie calls of early shell trumpets to the evolutionary miracle of spines and spires and the modern science of carbon capture inspired by shell, Barnett circles to her central point of listening to nature’s wisdom—and acting on what seashells have to say about taking care of each other and our world.

Languages : en
Pages : 222
Book Description
"A joy to read from two of the most prominent geologists who have worked for the better part of their careers in the Florida Keys. Places important environmental focus on modern-day issues facing the island ecosystems, the health of Florida Bay, the nearshore areas, and ultimately the reef tract."--Donald F. McNeill, University of Miami "A compelling narrative that weaves fascinating historical personalities and periods with the geological characteristics of the Florida Keys into a colorful tapestry. A fun, interesting, and informative read!"--Eugene C. Rankey, University of Kansas Two world-class geologists draw on their prolific fifty-year careers in this comprehensive guide to the geology and biology of the Florida Keys and Florida Bay. Eugene Shinn and Barbara Lidz dive into the past, present, and future of an area that has long been a natural laboratory for learning about coral reef formation and the origins of limestone. They explain how underlying Pleistocene topography controls the shapes of today's coral reefs, how sea-level rise created Florida Bay, and how hurricanes mold limemud banks and strip vegetation from the Florida Keys. They discuss the recent decline of coral reefs due to overpopulation, pollution, climate change, and other factors. An itinerary is included for a hands-on three-day field trip, guiding visitors to the best places to see the famous reef formations and geologic processes of the Keys. As glaciers continue to melt and reform at Earth's poles, sea level is currently rising and will fall again at some point in the geologic future. In this volume, Shinn and Lidz demonstrate the value of the Keys and immediate surroundings as an environmental laboratory to study past effects of sea-level change and to stimulate ideas for further research.

The Ecphoras
Author: Edward J. Petuch
Publisher: CRC Press
ISBN: 100088211X
Category : Nature
Languages : en
Pages : 306
Book Description
In the Miocene and Pliocene fossil shell beds of the eastern United States, the single most spectacular molluscan species radiation is seen in the ecphora shells (the Tribe Ecphorini). These bizarrely shaped gastropods, with their distinctive ribbed shell sculpture, represent a separate branch of the Subfamily Ocenebridae, Family Muricidae. Characteristically, these muricid gastropods are heavily ornamented with spiral ribs and cords and are considered some of the most beautiful and interesting groups of fossil mollusks found along the Atlantic Coastal Plain and Floridian Peninsula. The ecphoras are greatly sought after by fossil collectors. The ecphora faunas, and their individual species and subspecies, are illustrated and described in detail, along with photographs of ecphora-bearing geological units and in-situ specimens. The authors list the 67 known species and subspecies that are recognized as valid, arranged by the eight genera and five subgenera that encompass these taxa.

Seashells of Southern Florida
Author: Paula M. Mikkelsen
Publisher: Princeton University Press
ISBN: 0691239452
Category : Nature
Languages : en
Pages : 947
Book Description
Located where the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea converge, the Florida Keys are distinctive for their rich and varied marine fauna. The Keys are home to nearly sixty taxonomic families of bivalves such as clams and mussels--roughly half the world's bivalve family diversity. The first in a series of three volumes on the molluscan fauna of the Keys and adjacent regions, Seashells of Southern Florida: Bivalves provides a comprehensive treatment of these bivalves, and also serves as a comparative anatomical guide to bivalve diversity worldwide. Paula Mikkelsen and Rüdiger Bieler cover more than three hundred species of bivalves, including clams, scallops, oysters, mussels, shipworms, jewel boxes, tellins, and many lesser-known groups. For each family they select an exemplar species and illustrate its shell and anatomical features in detail. They describe habitat and other relevant information, and accompany each species account with high-resolution shell photographs of other family members. Text and images combine to present species--to family-level characteristics in a complete way never before seen. The book includes fifteen hundred mostly color photographs and images of shells, underwater habitats, bivalves in situ, original anatomical and hinge drawings, scanning electron micrographs, and unique transparent--shell illustrations with major organ systems color-coded and clearly shown. Seashells of Southern Florida: Bivalves is the most complete guide to subtropical bivalves available. It is an essential tool for students and teachers of molluscan diversity and systematics, and an indispensable identification guide for collectors, scuba divers, naturalists, environmental consultants, and natural-resource managers.
