Abstract
New records documented here demonstrate that Palaeocaris Meek and Worthen, 1865 was the most cosmopolitan and longest ranging (earliest Bashkirian to Gzhelian) fossil syncarid genus. It contains three species that are primarily known from occurrences in Euramerican Carboniferous Lagerstätten. Two of these species, P. typus Meek and Worthen, 1865 and P. secretanae Schram, 1984, have previously been reported from North America. We add a third species to the North American fossil record, Palaeocaris retractata Calman, 1932, from the Manning Canyon Formation (Bashkirian) of north-central Utah, USA. This is the oldest geological record of Palaeocaris and extends the temporal range of P. retractata back from its appearance in the transitional Bashkirian to Moscovian Bickershaw Lagerstätte of England by at least 4 million years. The Manning Canyon Formation occurrence expands the paleogeographic distribution of P. retractata from western Europe (England) to the northeastern edge of the Great Basin, USA.
期刊介绍:
Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils.
Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
