Book Description
Scandinavia and its Arctic territories of Svalbard and Greenland represent geographical regions with a long history of Mesozoic palaeontology. However the last few decades have witnessed a surge of new discoveries, especially from the famous Triassic and Late Jurassic Lagerstätten of East Greenland and Spitsbergen in the Svalbard Archipelago, together with the Late Cretaceous strata of southern Sweden and UNESCO World Heritage locality at Stevns Klint in Denmark; the latter recording one of the most complete terminal Mesozoic rock successions known globally. Collectively, these deposits encompass the spectrum of Mesozoic biotic evolution from the explosive radiation of marine faunas after the Permian-Triassic extinction and seminal specialization of amniotes for life in the sea, to the Late Triassic–Jurassic domination of the land by dinosaurs and Cretaceous development of modern terrestrial floras and marine ecosystems. This volume authored by leading experts in the field encapsulates key aspects of the latest research, and will provide a benchmark reference for future investigations into the Scandinavian Mesozoic world.

Book Description
The Mesozoic Era begins with the approximately 50-million-year-long Triassic Period, a major juncture in Earth history when the vast Pangaean supercontinent completed its assembly and began its fragmentation, and the global biota diversified and modern-ized after the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic. The temporal ordering of geological and biotic events during Triassic time thus is critical to the interpretation of some unique and pivotal events in Earth his-tory. This temporal ordering is mostly based on the Triassic time-scale, which has been developed and refined for nearly two centu-ries. This book reviews the state of the art of the Triassic timescale and includes comprehensive analyses of Triassic radio-isotopic ages, magnetostratigraphy, isotope-based and cyclostratigraphic correlations and timescale -relevant marine and non-marine bio-stratigraphy.

Book Description
What, precisely, is a primitive fish? Most biologists would agree that the living cyclostomes, selachians, crossopterygians, etc. cannot be considered truly primitive. However, they and the fossil record have served to provide the information which forms the basis for speculation concerning the nature of the original vertebrates. This symposium of biologists from a variety of disciplines was called together to create collectively, from the best available current evidence, a picture of the probable line of evolution of the prototype primitive fishes. The symposium was designed to follow one that took place in Stockholm in 1967, convened for a similar purpose, with about the same number of participants. It is a matter of interest that almost the entire 1967 symposium (Nobel Symposium 4) dealt only with the hard tissues, whether fossil or modern. In charting the course of the present symposium it was felt that the intervening years have produced numerous lines of new evidence that could be employed in the same way that a navigator determines his position. Each field, be it adult morphology, geology, ecology, biochemistry, development or physiology, generates evidence that can be extrapolated backward from existing vertebrate forms and forward from invertebrate forms. If the intersect of only two lines of evidence produces a navigational "fix" of rather low reliability, then an intersect, however unfocussed, of multiple guidelines from more numerous disciplines might provide a better position from which to judge early vertebrate history.

Book Description
This volume comprises 2 substantial papers that describe the Early Triassic (Smithian) ammonoids from the Salt Range (Pakistan) and the Spiti region of India. Ammonoids are abundant and well-preserved at many localities in these regions, and their highly resolved evolutionary succession is the key to stratigraphic correlation between the 2 areas, and with other Tethyan sequences such as those in southern Tibet and south China. Many new key genera and species are described.
