The presented paper contains a detailed description of four species of the genus Craniscus Dall, 1871,found in the Upper Oxfordian of Bielawy and Wapienno quarries, Kujawy area. Three of them: Craniscus bipartitus (Munster, 1837), Craniscus antiquior (Jelly, 1843) and Craniscus corallinus (Quenstedt, 1852) have already been described from Poland, the fourth, however – Craniscus tripartitus (Munster, 1840), had only been known from the Lower Oxfordian of North Bavaria. The Craniscus specimens come from slope deposits of sponge-microbialitic bioherm. This is indicated by the fact that almost all specimens are dorsal valves, separated posthumously from ventral valves. The condition of some specimens and the rock lithology suggests, that the deposition was very violent in some cases and brachiopods were buried alive. The studied material is relatively well-preserved, which alIowes an accurate reading of the location of muscle scal's.Downloads

Authors and authors responsibilities: Authorship should be limited to those who have made a significant contribution to the manuscript content. All those who have made significant contribution should be listed as co-authors. It is declared by the author(s) that manuscripts in all categories submitted to the journal and subjects to peer-review have not been published or submitted to any other journal or book. If the manuscript is written by several authors, the corresponding author should be indicated. It is declared that the corresponding author represents all the co-authors in certifying that all of them contributed meaningfully in preparation of the study, and that the final submitted version of the text is approved by all the co-authors. The author(s) should not publish in their study any copied part of the text and or figures from other sources without proper citation or permission (if necessary) – which is plagiarism – and stay in conflict with basal requirements of the authorship. All the authors are obliged to participate in peer review process, providing retractions or corrections of mistakes. The author(s) should indicate (the best in acknowledgements) the financial support and/or program within which the study has been prepared. Affiliation (all authors/co-authors) and corresponding address (main author) must be clearly stated.
Publication ethics and malpractice requirements: the Volumina Jurassica seeks to publish original work in the best possible form and to the highest possible standards. It is necessary to agree upon standards of expected ethical behavior for all parties involved in the act of publishing (authors, editors, peer reviewers, publisher). The Volumina Jurassica ethic statements are based on the guidelines and standards developed and published by the Committee on Publication Ethics (COPE- http://publicationethics.org/).
Anti-plagiarism Policy: Plagiarism is understood in the sense of the “use another person’s ideas or work and pretend that it is own’ (Cambridge Dictionary) or “the practice of taking someone else’s work or ideas and passing them off as one’s own” (Oxford Dictionaries), self-plagiarism (re-use of significant parts of one’s own copyrighted work without citing the original sources).
All articles in the Volumina Jurassica are supposed to be original. Authors submitting manuscript declare that submitted manuscript is original and has not been prepared from other published material. A paper should contain sufficient detail and references to permit others to replicate the work; any used information resources (phrases, data, images) must be appropriately cited or quoted.
Editors: the Volumina Jurassica editor is responsible for deciding which of the articles submitted to the journal should be published. The Volumina Jurassica editor will accept and evaluate manuscripts for their intellectual content only. Editors must not disclose any information about a submitted manuscript to anyone than stakeholders. The excluded from publication procedure are manuscripts which are beyond the scope of the interest of the journal (i.e. presenting the themes not related with the Jurassic System), and those evidently showing research misconduct (published elsewhere before, plagiarisms or bearing fundamental research mistakes). Unpublished manuscripts or materials must not be used in an editor’s own research. All submitted manuscripts will be considered for publication free of charge. When an author discovers a significant error or inaccuracy in own published work, it is the author’s obligation to promptly notify the Publisher and cooperate with the editor to retract or correct the paper.
