Book Description
​This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

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 highly fossiliferous upper Darriwilian to lower Sandbian Elnes Formation of Norway presents an interesting insight into the general responses and preferences of Lower Palaeozoic faunas belonging to a stable, mud dominated middle to outer shelf environment in connection with a major transgressive to regressive system tract. The rich trilobite fauna consisting of nearly 100 taxa is closely linked to the changes in the environment, being most abundant in a muddy and siliciclastic dominated environment just above storm wave base. The fauna is highly endemic for the region and the remainder of Baltoscania. This monograph presents a taxonomic description of the total trilobite fauna, including a new genus and seven hitherto unknown species. New and extensive biostratigraphical data is presented on the trilobites together with a study on the biogeographical and ecological aspects of the faunas.
