C.O.R.E. Group

Founded 2005 the international C.O.R.E. Group, as an informal international research alliance with a common interest in the exceptionally 3D preserved 'Orsten' fossils from the Cambrian has increased to around 40 members from no less than 8 countries from 4 continents plus Japan (member list). CORE means Center of 'Orsten' Research and Exploration (C.O.R.E.) and refers to the workgroup around Dieter Waloszek at he University of Ulm.

CORE also stands for an excellent example of a fruitful alliance of Biology and Palaeontology in order to improve our understanding of animal evolution (Metazoa). Study objects of the CORE Group are in the main the 'Orsten' fossils themselves and the geology around the 'Orsten'.

Main issue is the concentration of expertise about the 'Orsten' and its fossils, the sites in which these occur, and related topics, last but not least the dissemination of information on the 'Orsten'.

To serve these purposes we created this website, with simple tools, so not as perfect as others, but we try to add more information continuously, correct and update the content as regular as possible. The website includes information about the Orsten and background data, information of the animals discovered from the Orsten and images of them and relevant literature, much of it to be downloaded as PDFs, also several papers from the CORE members (otherwise pick their email address from the contacts page and ask directly. We also listed all papers by the founder Klaus J. Müller, most again also available as PDFs. Due to limited space at present we regret to have a little delay in putting more pdfs on our pages. We try to do this as soon as possible. We also try to figure out how to use an easier-to-use CMS tool for the website.

At present we are still having some bias on information about the Swedish 'Orsten' lagerstätten, but we hope to add more from other 'Orsten' fossiles sites, such as in China, the UK (Comley), Poland, and Australia progressively. Localities from these countries contribute not only significantly to our knowledge about and around the 'Orsten' not only by adding different species, but they also add to our knowledge about other things like lithological, perservational and taphonomical issues. And they expanded the time frame of 'Orsten' occurrences considerably.

Lastly, and of course, the fossils from the new localities helped to improve and widen our evolutionary interpretations significantly (see, e.g., papers from 2007, published in Nature in 2007, from 2010, published in Current Biology, or the more recent papers by Maeda et al. 2011, Terfelt and Erikson in 2012 or by our Chinese colleagues from 2012 and 2013 – link to publications above).

On March 12, 2010 the discoverer of the Orsten, our dearest colleague, friend, Klaus J. Müller, had passed away, age 87.

Until last, Klaus was interested in many things and was even working hard on a book on gemstones, his main and long-lasting hobby over the past. We all benefitted very much from Klaus' great scientific work and likewise knowledge, and we are very grateful that he could have been around supporting us for so long.

Thank you so much, Klaus, for a wonderful time together and the topic you provided us with!
