General policies

Micropaleontology publishes peer-reviewed research of regional and international significance on the systematics, biology, evolution, distribution and ecology of microfossils and their living representatives. Other research on the applications of micropaleontology in earth history may be more appropriately directed to our companion journal Stratigraphy

We also accept unreviewed short notes with professional information, such as preparation techniques and taxonomic changes. Book reviews, memorials, and announcements of meetings and other professional events are welcome.

Terms and conditions

Manuscript must be in English, submitted via the Micro Man online manuscript manager.

There are no page or plate charges, and no restrictions on color illustrations. Aside from practical limitations there is no fixed limit on number of pages or plates. Authors should expect to pay the cost of fold-out pages. The lead author will receive a password, which may be shared with co-authors, for a 30-day subscription to the journal, to allow downloading of the published article for sharing with colleagues, as well as access to the archived contents of the journal.

COPYRIGHT NOTICE: By the act of returning the final page proof of the manuscript, the author(s) agree to grant to The Micropaleontology Press Foundation, Inc., the full undivided copyright to their work in the final published form, including the right to grant reproduction of the published work or portions therof for scholarly use, with full acknowledgment.

Submittal and review

Please look over the main points of Micropaleontology requirements before submitting manuscript. Detailed instructions and suggestions are found below.

Style: Most questions of style can be answered by looking through recent issues of the journal.

General usage: We do not dictate planktic or planktonic, benthic or benthonic, stratigraphic or stratigraphical, and so on, where there is precedence for either one. The use of a conjunction such as and, but, then, however, therefore, nonetheless to begin sentences is deplorable. Periods and commas are not placed inside a quotation or parenthesis if they are not an original part of the phrase. Fowler's English Usage is a good general source for word usage, punctuation and other such matters. For scientific writing questions, we recommend Suggestions to authors of the United States Geological Survey.

Title: The title should be as brief and clear as possible, identifying the subject of the paper without superfluous detail as to location, age, etc.

Abstract: Summarize the points made in the paper, rathe than merely list the contents.

Author: Author names are written out in full. Where there is more than one author the corresponding author (if not first listed) should be indicated in the cover letter. The institutional address of each author should be no more than is necessary for identification; complete postal address or organizational information beyond this level is not desirable. E-mail address of the senior or corresponding author is required, and those of other authors should be included if possible.

Text format: Text documents (including captions and references) are double spaced, 11 point, left justfied. Note that submittals are manuscripts, not publications! Refinements simply for the sake of appearance, such as forced hyphens, underlines, boldface sentences, embedded images and so on are not appropriate, and must be removed by the editor before the paper can be prepared for publication. Complex mathematical statements and other expressions using special characters or diagrammatic notation should be submitted separately as graphics. Serial and book titles, and phrases in foreign languages should be italicized. Phrases taken from context are identified by quotation marks and, if possible, referenced to page. If quoted text is extensive, it should be indented.

Subject heads: There are four levels of subject heads, as follows: top level in ALL CAPITALS ROMAN BOLD FACE; second level in lower case Roman bold face; third level in lower case italic bold face, and the fourth level in lower case italics, regular. Except for the all-cap top level, only proper nouns should be capitalized. The top three levels must be on a separate line without a following period or other punctuation (except for query? and exclamation point!). The fourth level, or "run-in head", is placed in the first line of a paragraph, followed by a period or colon. Note that outline format, with letters and numbers identifying paragraps, is not acceptable, and no footnotes are allowed.

Superscript, italics and bold face should be executed, not merely indicated.

Abbreviations: The conventions for units of measurement are considered to be symbols, not abbreviated words, and thus do not use periods (km, cm, mm, Ám, nm, mi, ft, in, kg, g, lb, oz, hr, sec). Periods are omitted as well from abbreviations of the more common titles (Dr, Mr, Mrs, Ms, Sr, Jr, PhD) and the letters in acronyms. Common acronyms (such as USA, UK, USGS, NY, DSDP, etc.) need not be explained, but where needed, it is the acronym that should be explained -- e.g., "UCLA (University of California, Los Angeles)", not "University of California, Los Angeles (UCLA)".

The geochronometric expressions Ma (meaning "million years before present") and ka (meaning "thousand years before present") are abbreviated phrases. They are not interchangeable with Myr and kyr, the abbreviations for simple quantities of years.

The commonly abbreviated latinisms (etc., et al., viz., e.g., s.s.) are not italicized. On the other hand ex and et are foreign words, and are therefore italicized, as is vs for versus, which by convention is italicized without a period.

The term "et al." should be used only in place of more than three (not more than two) author names. "Et al." stands for the authors included, and no others; two papers by "Author et al." cannot be treated as repetitive unless all authors are the same.

Lists in text: Lists of data that use tabs or spaces to position the information in columns within the submitted text, create serious problems in page-making. These lists should be submitted separately as Word files, with numbers corresponding to numbers inserted in the main text to indicate their location.

Size estimate: A full page of text in Micropaleontology will contain approximately 1,000 words, or 5,200 characters including spaces; this is between 3 and 4 typescript pages, depending on author's font and spacing. The captions to plates and figures take up more area, equivalent to 600 words per full page.

Illustrations: Photographic and other shaded images should be prepared in grey-scale TIF or JPG at 300 to 360 dpi. Line art (diagrams, tables, maps) should be in black and white TIF or JPG at 1000 to 1200 dpi. Powerpoint files are not acceptable, and Excel spreadsheets and Word tables must be scanned as graphic images. Reduced-size copies (less than 100 Kb each) should be used in the first submittal to make reviews easier to manage, but full size images will be required for publication.

Full-page plates and figures should be prepared with an aspect ratio of 0.74 width to height, sized to 7 x 9.5in (177 x 235mm). Half-column graphics will fit a width of 3.25 inches (85mm). Figure numbers and superimposed arrows, labels, and other identifiers should be inserted on plates and figures by the author no smaller than 8 point at published scale. No caption, however, should appear on the plate, and explanations for symbols should be included in the caption as far as possible. Any "sideways" text on tables and diagrams should be placed to run upwards when the left side is down, so that the words will be correctly oriented when the page is turned clockwise.

Captions: Captions should begin with a brief descriptive phrase, e.g., "Index map of sample sites." The abbreviations and graphic symbols used in the figure or table should be explained in the caption rather than in the graphic, as far as possible. When the same explanations apply to a series of figures, it is only necessary to explain them completely in the first caption. A long caption, bringing out the point of the figure or table, is preferable to a cursory statement that merely identifies the content, even if the caption repeats discussion that is also found in the text.

Footnotes are not permitted.

Taxonomic terms: In the body of the paper, we ask that all taxonomic names, when they are first mentioned, are given in full, with author and date. (Names used solely as descriptors, as in biozones or biofacies, are exempt). In papers that do not have a systematics section or list, it is desirable that this first citation should include the original combination for a reassigned taxon, as follows: Aus cus (Jones) (=Aus bus, 1900).

Citations: Author last name and date without a comma, and with page or plate number added if necessary, as follows:

"We refer to papers by Author (2005; 2006) and Author, Otherauthor and Lastauthor (2007)."

"We agree with other workers (Author 2005; 2006; Author and Otherauthor 2006)."

"We note a statement by Author et al. (2005, p. 101).

Synonymies:These do not need to be complete histories of a combination, but ideally should cover the significant citations. The example below is adapted from W. Kiessling's (1999) Late Jurassic radiolarians from the Antarctic Peninsula, Micropaleontology, v. 45, supplement 1, p. 46. Citations in synonymy need not be included in the list of rereferences. The taxon under discussion is shown in boldface italics.

Genus Perispyridium Dumitrica 1978
Type species: Trilonche ordinaria Pessagno 1977a.

Range and occurrence: Middle Jurassic to late Jurassic, early late Tithonian. Worldwide in all known provinces.

Perispyridium ordinarium (Pessagno)
Plate 10, figs. 9. 10.

Trilonche ordinaria (?) PESSAGNO 1977a, p. 79, pl. 6, fig. 14
Trilonche ordinaria Pessagno - WAKITA 1982, pl. 6, fig. 9
Perispyridium ordinarium (Pessagno) group - BAUMGARTNER et al., 1995a, p. 418, pl. 3100, figs. 1-6 (with complete synonymy).

Curatorial information: The field location of type material, and preferably that of all described specimens, must be given as exactly as possible. A good rule of thumb is to describe a locality well enough for later workers to be able to duplicate the sample. Wherever possible, specimens should be tied to individual sample localities on a map, or to individual sample levels in sections and cores. The depository and catalogue identification of all described material is required.

Taxonomic rules: ICZN is used for heterotropic protozoans such as foraminifera, radiolaria, and tintinnids. ICBN applies to the "algal" (i.e., chloroplast-bearing) protists including diatoms, coccoliths, silicoflagellates, ebridians, prasinophytes, acritarchs, and dinoflagellates. Botanical rules of taxonomy also apply to Bacteria.

List of References: Cited works are listed alphabetically by author name (in CAPITALS) and then chronologically. Note that "Mc" comes in order, and not before "Mac". Honorifics are detached (for example, write ORBIGNY, A. D', and GUEMBEL, C. W. VON). Serial and book titles are italicized and spelled out in full. The issue number is not indicated unless the issue is separately paginated. All words in serial titles are capitalized but only proper nouns in book titles. Genus and species level names in article and book titles may be italicized.

AUTHOR, A. A. and COAUTHOR, C. C., 1998. Article title. Serial Name Spelled Out in Full, 1:23-45.

__________, 1999. Chapter or paper title. In: Editor, E., Ed., Book title spelled out in full, 12-34. City: Publisher. Series or sponsor, no. 100.

AUTHOR, A. A. and OTHERAUTHOR, O. O., 1990. Book title spelled out in full. City: Publisher, 1234 pp., 56 pls.

The final name in a list of authors is not set off by a comma before the "and" or "et al." Authors that are exactly repeated without change in successive references are replaced by a dash.

Written or verbal communication that is noted in the text should not be cited in the References. The titles of unpublished reports, student papers, dissertations, and posters should be given in quotes. References posted on the internet are considered to be publications; where both printed and online versions exist, the doi is not required.

A work may be listed in the references if it is actually in press, i.e., formally accepted for publication, but no year or volume number needs to be indicated.

Submittal: Manuscript should be submitted in digital form using the manuscript manager Micro Man, on our website, where details can be found.

Review: Reviewers are anonymous, unless they wish otherwise. The help of reviewers who identify themselves should be acknowledged in the final draft. The review comments, marked-up manuscript and editor?s remarks will be available in Micro Man after the author is notified (but not before) The authors must satisfy the Editors, not the reviewers, in preparing a final draft acceptable for publication.

Final draft: The corrected manuscript must be submitted in Micro Man, with text in MS Word or rtf and full size illustrations. Documents with the same name will overprint earlier versions.

There is no time limit for returning a final draft. Authors may not, however, introduce significant new data, or substantially change the scope or purpose of the work after review, without consulting with the Editor. In such cases a second round of review may be called for.

Proof Corrections: Authors receive full-page mockups. Corrections may be returned by email, as comments, revised sections, or scans of marked up pages to the editor. We do not ask for complete proofs to be returned.
