Manuscripts preparation : Three complete copies of manuscripts should be submitted on A4 size (297 x 210 mm) sheets. Manuscripts are to be written in English in a simple style. Care should be taken to avoid long and complicated sentences and unnecessary jargon. The text is to be organized as Abstract, Introduction, Methodology, Main body including Data, Results and Interpretations, Discussion, Summary and or Conclusions, Acknowledgements and References. The length of the abstract should be limited to 250 words. It should summarize the results rather than contents of the paper and should include all new taxonomic names. Citation of literature in the abstract is discouraged. The headings and subheadings should be numbered hierarchically (such as 1/ 1.1/ 1.1.1 etc.). This numbering serves as an aid in editorial process and is deleted in the final layout. The text should be printed double-spaced on one side of the paper with 30 mm margin on each side. Only names of genera and species are to be set in italics. Foot notes are not allowed.

Literature citations in the text should be formatted as follows : Author (1990: 525) or (Author 1990 : 525). Two author are linked by “&”: Author & Author (1990 : fig. 2). Three or more authors are abbreviated by “et al.” after the first author : Author et al. (1990). References are separated by a semi colon “;”and year by a coma “,” : Author 1990; Author 1995, 1996). Citations of figures, plates and tables are written in small letters : (Author 1990: 56, pl. 4, fig. 5) or (Author 1990 : 56, text-fig. 4, tab.4). Note that there is no coma between authors name and year of publication.

All pages of scripts, including references and explanations of illustrations, should be numbered consecutively. Papers on palaeontology must strictly follow the most recent issues of the International Codes of Zoological Nomenclature (ICZN) and Botanical Nomenclature (ICBN). In making any stratigraphical changes or erecting new stratigraphic terms the International Stratigraphic guidelines should be followed. As per the recommendations of ICZN and ICBN, all illustrated and described fossils must be registered and deposited in an appropriate permanent institution. The register number and the name of the repository (Institution) must be quoted.

Illustrations : Illustrations must be submitted camera-ready for copying and they should be numbered in the same sequence that they appear in the text. The author should mark the desired position of each figure and table in the left margin of typescript pages. When designing figures, tables and plates it is important to keep the maximum size of the printed illustration in mind (full page format : 230 mm high and 180 mm wide in two columns, single column format : 230 mm high and 85 mm wide). Please note that hand-made line drawings generally benefit from reduction whereas photographic illustrations do not. So potential reduction of illustrations is to be kept in mind especially with regard to lettering. After reduction to column or page size, the smallest letters should be at least 8 pt). All figures, tables and plates are referred to in the text with capitalized abbreviations like Fig. 1, Tab. 2 or Pl. 3. A scale bar should accompany line drawings as well as photographs of specimen; its length is to be indicated in the figure-caption.

Fold-out tables are not acceptable. If a table of larger than page size is essential, it should be arranged for two facing pages. Fold-out maps, and colour plates may be considered for inclusion only if essential - for both a contribution towards the extra cost involved will be expected from the author.

The author should retain original illustrations until the manuscript is accepted. Review copies must include high-quality photographs of halftone illustrations; photocopies are acceptable only for line drawings. Digital versions of line drawings are encouraged (in CDR files) but they should be accompanied with high quality laser printouts. Each plate and photographic figure should be protected by an overlay attached along the upper edge.

References: The authors are organized in alphabetical and chronological order, every author separated by coma “,”. References by the same author, published in the same year should be distinguished by the use of suffixes : 1999a, 1999b, 1999c. All author names are set in small letters. Publication/journal name are given in full title/name. Volume numbers are printed in bold and issue numbers are given in parenthesis followed by a coma and page numbers.

Examples:
Author, A. 1998. Title of paper. Full name of journal, 11 (2) 205-221.
Author, A. 1999a. Title of paper. Full name of journal, 12 (4) 215-222.
Author, A. 1999b. Title of paper. Full name of journal, (New Series), 10 (5), 108-121.
Author, B., Author, C., Author, D. 1999. Title of paper. Full name of journal, 32, 295-300.
Author, A. 1999. Title of book. Name of Publisher, place of publication, 280 p.
Author, A. 1999. Title of contribution. In: Editor, A (ed.), Title of book. Name of Publisher, place of publication,150 p.
Author, A., Author, B. 2000. Title of contribution. In: Editor, A. & Editor, B. (eds.), Title of book. Name of Publisher, place of publication,150 p.

Electronic version of manuscript : After the acceptance of a paper the authors are required to submit an electronic version of their manuscript in MS-Word for Windows file on a CD-Rom formatted for windows. The electronic text may be formatted as follows: use 10 pt Times New Roman font, justify margins only, do not hyphenate words, set generic and specific names of taxa in italics. Number headings and subheadings hierarchically (such as 1/ 1.1/ 1.1.1 etc.) and do not underline them or set in bold/italic. All author names in text as well as list of references are set in small letters.

Cover Photographs : High quality photograph (BMP file on min 300 resolution) related to the submitted manuscript is welcome for use on the cover page. A colour transparency and one colour print of at least 125x175 mm size will be required. A legend giving the geological interest of photo and a credit line should be given.

Publication time : Currently the time between initial submission and publication of regular articles is about 1 year. Articles accepted for publication are generally published in order of submission. Exceptions can be made for papers of high scientific significance.

Reprints : Authors receive 50 free reprints. Additional reprints can be ordered at cost.
