Click the link for an index of research papers published following the Proceedings of the International Symposium Coleoid Cephalopods Through Time, September, 2002, Berlin. Many of these 25 papers listed will be notable to anyone interested in modern cephalopod biology, not just fossil forms. All are in .pdf format and can be downloaded in full.

Of particular interest to to those who study extant squid is what must have been one of Kir Nesis' final papers: Distribution of Recent Cephalopoda and implications for Plio-Pleistocene events. Aloso recommended is MR Clarke's Potential of statoliths for interpreting coleoid evolution: a brief review.

Quick introduction to the articles:
Coleoid cephalopopds form a considerable part of the marine biomass, and they are an increasingly important resource for the nourishment of humans. Our knowledge of extant coleoids, their biodiversity, ontogeny, phylogenetic relationships, behavior, and ecological conditions is still incomplete, particularly concerning the species living in pelagic zones and in deepwater. Also the fossil record of coleoids, which are known since the Palaeozoic, is very poor because of their generally reduced hard parts which presuppose extraordinary preservation conditions (“fossillagerstätten”). Besides the calcitic rostra of belemnites, which frequently occur in Jurassic and Cretaceous sediments, our knowledge of coleoids is based mainly on softbody fossils of only a few preservational windows, like the Solnhofen plattenkalks, in contrast to ectocochleate cephalopods, for which we find billions of fossil shells of both nautiloids and ammonoids in marine sediments throughout the world.

In order to focus on the actual research activities devoted to fossil and living coleoids, the first international symposium “Coleoid Cephalopods through Time” was held in September 17-19, 2002 at the Freie Universität Berlin in collaboration with the Graduate Program “Evolutionary Transformations and Mass Extinctions; about forty specialists in this field from all over the world discussed relevant questions very effectively. The interdisciplinary blend of biologists and palaeontologists mutually opened the understanding of many new aspects.
