Excerpt from Fossil Sponge Spicules: From the Upper Chalk Found in the Interior of a Single Flint-Stone From Horstead in Norfolk In the following pages I have attempted to give a description of the forms and affinities of a number of sponge spicules which were present, with a number of other organic remains, detached and heterogenously mingled together, in the cavity of a single flint stone, from strata of the Upper Chalk Formation, at Hor stead, a village but a few miles distant from the city of Norwich, England.

Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.
