Book Description
Paleontologists and geologists struggle with research questions often complicated by the loss or even absence of key paleobiological and paleoenvironmental information. Insight into this missing data can be gained through direct exploration of analogous living organisms and modern environments. Creative, experimental and interdisciplinary treatments of such ancient-Earth analogs form the basis of Lessons from the Living. This volume unites a diverse range of expert paleontologists, neontologists and geologists presenting case studies that cover a spectrum of topics, including functional morphology, taphonomy, environments and organism-substrate interactions.

Book Description
Sitting squarely at the interface between earth and life sciences, palaeobiogeographic information is scattered throughout many publications. Until now. Palaeobiogeography of Marine Fossil Invertebrates covers important theoretical concepts relating to palaeobiogeography together with descriptions of analytical methods. Fabrizio Cecca discusses general biogeographical concepts and the factors influencing distributional patterns using illustrative case histories. Cecca uses the palaeobiogeography of fossil organisms to generate hypotheses on continental drifting, past migration routes, palaeobiodiversity gradients, geographic barriers, palaeoclimatic and paleooceanographic conditions. He explores the biogeographical dimension of biodiversity through the analysis of existing latitudinal and longitudinal gradients of biodiversity and discusses the biodiversity/area relationship with particular reference to sea-level variations.

Book Description
The shallow-shelf carbonates of the Lower Border group and equivalent strata of the Northumberland trough have yielded conodont elements belonging to 28 multielement species. Study of these cavusgnathid-dominated faunas highlights the need for major revision of the Cavusgnathidae. Cloghergnatus globenskii Austin is an ecophenotype of Taphrognathus varians Branson and Mehl; Cloghergnathus Austin is ajunior synonym of Taphrognathus Branson and Mehl, Capricornognathus Austin appears to be a junior synonym of Patrognathus Rhodes, Austin, and Druce. The appartuses of Cavusgnathus hudsoni (Metcalfe), Taphrognathus varians, Polygnathus mehli Thompson, and Apatognathus cuspidatus Varker are described for the first time. Patrognathus capricornis (Druce), Mestognathus beckmanni Bischoff, Polygnathus bischoffi Rhodes, Austin, and Druce, and "Apatognathus" sp. a are partially reconstructed. The assignment of C. hudsoni to Cavusgnathus extends the range of the genus into the Tournaisian Series in Britain.

Book Description
This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time. The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.

Book Description
Approximately 3000 middle and late Cenozoic nearshore marine molluscan taxa from western California are assigned to six time periods, spanning ~25 m.y. In this interdisciplinary study, western California is palinspastically restored for each of the time periods by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. In addition, this volume reveals positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; defines "equable" based effective temperatures; and analyzes extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline.
