Special Papers in Palaeontology, published by The Palaeontological Association, is a series of substantial separate works conforming to the style of the Palaeontology journal. Two issues are published each year and feature high standard illustrations. Investigates the shell-rich Llandovery strata of the Anticosti ramp and presents the orthide brachiopods which reached their evolutionary diversity acme and abundance in the Ordovician Highlights the nine families of orthides which were lost at the end of the Ordovician, but discusses how some 16 families crossed the boundary (though mostly showing declines in the Silurian) Greatly expands the old locality register and enables the accurate placement of known and new species in a stratigraphic, evolutionary, as well as type locality framework Brings together researchers, geologists and enthusiasts who continue to find material of significance Includes 19 plates and 14 text-figures
A monographic study that deals with a major marine faunal turnover during the Late Ordovician global greenhouse/icehouse episodes. It aims to document the diversity change of brachiopods (one of the major groups of marine life during the Ordovician Period) from pre-extinction to extinction times.
A monograph on New Mexico fossils from the Special Papers in Palaeontology The non-marine, trace fossils in New Mexico are the subject of this publication. Ichnology of an Early Permian Intertidal Flat: The Robledo Mountain Formation of Southern New Mexico describes and illustrates both the invertebrate and vertebrate trace fossils found in an upper intertidal flat setting. Eighteen invertebrate ichnogenera are described. Previously described vertebrate ichnogenera and ichnospecies are reviewed, along with a description of a new ichnospecies.
Because of their generally great abundance and high diversity, brachiopods from the Red River and Stony Mountain formations of southern Manitoba are important to understanding the pattern, process, and rate of evolution, radiation, and extinction of the North American epicontinental marine shelly benthos during the Late Ordovician. This report presents a detailed taxonomic treatment of these brachiopods, coupled with an assessment of their implications for biostratigraphy, palaeoecology, and palaeobiogeography at continental and global scales.
