Summary

The summary must be submitted in Spanish, and its translation in English. It should not be longer than 500 words, but it should not be too short. The summary must contain the following elements:

1. Originality/value
2. Objectives/design/methodology/approach
3. Results
4. Study limitations/Study implications
5. Findings/conclusions 

The summary should not include abbreviations nor bibliographic references. Should the text be in English, a summary in Spanish must be included as well. 

In addition, authors must provide a brief non-technical summary in both Spanish and English. This summary should explain the key aspects of the article in a way that is accessible to a general audience, avoiding technical jargon and simplifying complex concepts. The goal is for anyone, regardless of their background, to understand the main points of the research.

Keywords

Include four to six keywords in the summary and abstract. The keywords will be the same and will be placed at the end of these in alphabetical order.

Main Text

Here are some guidelines to consider when preparing the manuscript:

1. Authors are expected to use the language correctly (spelling, punctuation, grammar, syntax). If possible, the review by a native speaker is recommended when the text is not written in the author's mother tongue, if this is not the case, it is requested to notify us so that we can get a native reviewer and thus not affect the publication date of the work submitted.
2. The chapter and subchapter heading will adjust to the following hierarchy:

1.FIRST LEVEL (Upper case, bold, left-aligned)

1.1 Second Level (Upper case and lower case, bold, left-aligned)

1.1.1 Third level (Upper case and lower case, italics, bold, left-aligned)

1.1.1.1 Fourth level (Indentation of 0.75 cm, upper case and lower case, italics, in a row)

If possible, avoid excessive subcategorization of the text. If more sublevels are required, titles may be written with upper case and lower case letters, preceded by a), b), c), etc. These titles should be placed at the beginning of the paragraph, leaving an indentation of 0.75 cm and ending with a period. 

1. Chemical analysis and radiometric or paleontological dating must be referred to the sampling location, reporting the geographic coordinates.
2. Units of measure of any type will be represented by their symbol in the International System of Units (BIPM, 2006).
3. If the work includes equations, they must be numbered consecutively. All terms contained in the equations must be defined immediately after presenting the equation. References to equations in the text will be made as: Equation 1 or (Equation 1).
4. The formal or informal character of a lithostratigraphic unit will be denoted following the criteria established in the Code of Stratigraphic Nomenclature (NACSN, ​​1983; North American Commission of Stratigraphic Nomenclature, 1984), the International Stratigraphic Guide (ISSC, 1994) and the International Stratigraphic Chart (ICS, 2008).
5. If statistical analyses are used, the statistical values ​​should be included in the Results, as well as within the text or within the tables. The degrees of freedom and the value of P for each reported result (for example, for a test of t = 34.41, gl = 1, P = 0.03. While for an ANOVA, F5 = 26.45 is reported, P <0.001) should be included in the statistical values. Use P for significance and p for probability.
6. It should be verified that all bibliographic citations referred to in the text appear in the list of references at the end of the text and vice versa. Only the last name (s) of the author will be cited as it appears in the original work without including names or initials, followed by the year of publication: (Aguillón-Robles, 1994; Robert and Bulot, 2005). In citations to corporative authors, acronyms can be used: (FAO, 1998). If the author's name is part of the sentence, only the year will be written in parentheses: "According to Aguillón-Robles (1990) ..."
7. References in the text must be cited in chronological order, and in ascending order, using the letters a, b, c, etc., to differentiate the citations of an author (s) with the same year of publication. Separate with commas the references of the same author (s); separate citations from different authors with a semicolon: (e.g., Persson, 1960a, 1960b; Keller, 1977).
8. When the cited work has two authors, the last names of both will be included (e.g., Hoffman and Feigerson, 1983); if it contains more than two authors, the first author will be cited followed by "et al." in italics (e.g., Carmichael et al., 1974).
9. Preferably, citations or references to works in preparation, submitted or under review should not be included. If necessary, keep them to a minimum. Publications in the press and that are available online must include DOI or link to the website where they are available. Similarly, references to personal communications should be avoided unless they are written communications. These will not be included in the list of bibliographic references.
10. The authors must avoid the excessive use of auto citations and keep them below the 20% of the total of citations used.
11. For words and abbreviations in other languages ​​(such as e.g., or i.e.) they should be written in italics. The exceptions will be the notations used in the systematic nomenclature, such as: cf. and / or aff.; in the case of "?" when it is placed in the names of taxonomic levels such as genus and species, it will be written with a normal font. 
12. Regarding the use of long dash (—) and short dash (-), it is necessary to take into account under which context it is used. The short dash is usually used in compound words and acronyms, in either English or Spanish. The long dash is used to indicate numerical intervals, for example, pp. 56—98 or fig. 7—10. It can also indicate time periods (e.g., Triassic—Jurassic).
13. Authors must register nomenclatural acts related to the creation of new taxa in Zoobank or another official nomenclature registration platform, as stipulated by the regulations of the International Commission on Zoological Nomenclature. If the authors do not complete this registration before submitting the manuscript, the journal will proceed with the nomenclatural registration and will publish the article only once the corresponding registration has been obtained.

Systematic palaeontology 

1. All the specimens described or illustrated in the work must be registered and housed in an appropriate institution that guarantees the permanent preservation of the material for future study. Each copy must have a catalogue number that identifies them and it must be cited in the manuscript.
2. All taxa cited for the first time within the text of the manuscript, in lists, appendices and / or figures must have an author and date. The citation must appear in all cases in the Bibliographic References section.
3. In cases where there is more than one author of taxonomic hierarchies, all authors must be cited, avoiding the use of et al., and the term “and collaborators”. Before mentioning the last author, the conjunction 'and’ must be used instead of '&'. Omit spaces between a question mark and a generic name (e.g., Moreno-Bedmar?).
4. For visual elements within the manuscript, the term "figure" must be used, and the term "plates" should be avoided. If there are several elements within the same "figure", they should be cited as Fig. 2.1 or Fig. 2A.
5. Only in the list of synonymy (list of the designations of the taxon that go from the oldest to the most recent) will the references to plates be used whenever applicable.
6. Authors must follow the indications for the headings indicated in the section “Manuscript format”.
7. The extension of the headings must be according to the management of each group, but it must be used consistently for all the treated taxa.
8. It must be cited at least from the Family level, leaving the mention of higher taxonomic categories to the author's discretion in case there is controversy in their use.
9. For all the mentioned taxa, the author and date must be cited. Taxonomic hierarchies must be in a centered format. In the Bibliographic References section, the references of the authors of each taxa cited in the Paleontological Systematics section must be included.
10. Followed by the generic and / or specific name, the Synonymy, whose extension is at the discretion of the author, must appear. Start with the oldest work (which is preferably the original designation), mentioning the page on which that species refers, followed by the plate (s), and, finally, the figure (s) of the species in question. The quotation must be in justified format, and successive lines must be indented.
11. When citing the plates and / or figures, the Roman numerals must be converted to Arabic, except in cases where confusion is created.
12. In all topics, references to figures, plates, and pages of cited works should be written in lower case and abbreviated (plate, fig., Pl., P.). When citing plates and / or figures within the synonymy, the format must be homogeneous following the above indications, that is to say that if it is cited in an abbreviated form (Pl), it should be done in the entire synonymy avoiding different formats in the abbreviations such as Plate, Pl., Etc.
13. Like the figures in the rest of the manuscript, the plates in the synonyms must be cited in order: pl. 2, fig. 3; pl. 5, fig. 4, etc. Taking into account that any allusion to plate / lamina implies that it will be composed of several figures, which must be cited in order.
14. For all new taxa, a formal and complete systematic treatment is necessary. For the previously named taxa, a complete systematic treatment (diagnosis, description, synonymy, etc.) is not necessary.

When a new genus is described:

Name of the genus, followed by the connotation “new genus”

Holaster simplex Shumard, 1853

Figure 1, g-j; figure 2.

Holaster simplex Shumard, 1853, pp. 210. Clark, 1915, pp. 85, pl. 34, fig. 3a-b; pl. 38, fig. 1a-j. Cooke, 1955, pp. 107, pl. 24, fig. 6-8. Buitrón, 1971, pp. 25-27, pl. 5 figs. 9-10, pl. 6. figs. 1, 2, 4. Akers and Akers, 1987, pp. 80.

Holaster laevis (Brogniart, 1822). Cooke, 1946, pp. 234, pl. 34, fig. 1-3.

Description Medium-sized head, cordiform, with convex apical face and flattened oval face with the exception of the plastron, which is slightly protruding and the concavity where the peristome is located. The posterior surface is truncated, and the anterior surface is smoothly rounded and faded. It is cut in the center by a superficial sulcus that runs from the apical apparatus to the peristome. The odd, non-petaloid ambulacrum is housed in a sulcus, and the poriferous zone is constituted by pairs of pores arranged diagonally, round, very small and widely spaced. The anterior ambulacra pairs are subpetaloid, broad and slightly curved towards the anterior part; the poriferous zone is made up of pairs of slot-shaped pores, very close to each other and to the next pair. The anterior series is narrower than the posterior. The posterior ambulacra are subpetaloid, straight and are made up of rows of slot-shaped pores, the same as those of the posterior series of anterior ambulacra. The apical system is central and elongated, with four genital plates, separated two by two by ocular plates. The central and posterior ocular plates are joint. The periproct is vertically oval and located in the lower part of the posterior wall. The peristome has a rounded contour and is located in the anterior part of the base of the head (taken from Buitrón, 1971).

Examined material 6 specimens conserved in calcite numbered as IGM-1600, IGM-1601, IGM-1602, IGM-1603, IGM-1604, IGM-1605 and IGM-1606 were worked with.

Distribution for Mexico Turonian (Cretaceous) in Indidura Formation, north of Tanque Toribio, Sierra de Santa Ana, Coahuila (Buitrón, 1971).

Discussion The genus Pseudananchys is believed to be a paraphyletic group due to the exclusion of the genus Echinocorys, synonymous with Ananchytes (Smith and Kroh, 2011). Nieto and García (2006) report Ananchytes striata and A. sulcatus for the Cretaceous of Mexico; however, reports of these species were only found in Europe. The genus Holaster is currently also considered paraphyletic due to the exclusion of Cibaster, Offaster, and possibly other genera (Smith and Kroh, 2011).

Figures

1. Figures (maps, graphs and photographs) will be delivered independently (in TIFF or JPG format with a minimum of 300 dpi for its final publication) and must be named according to their position within the text. Example: Figure 1 or Figures 1 and 2.
2. Use “Times New Roman” font inside the figures, with a minimum font size between 7 and a maximum of 12 points. If the figure contains several images with a background, they must be separated by a white or black line (depending on the background of the image and its contrast) with a thickness between 1 and 2 mm. If the images do not have a background, it will not be necessary to separate them by lines. Use graphical scales within the figure instead of magnification factors. The magnitude to which the scale corresponds (e.g., cm or mm) may be included within the figure or in the figure footnote.
3. None of the illustrations should be presented as 'Plate'; all must be included as consecutively numbered Figures.
4. Maps must have the North indicated and have at least two coordinate data on each axis, and a graphic scale. The geographic locations referred to in the text must be included on the map.
5. References to figures in the text will be made as: Figure 1 or (Figure 1). The reference to figures in other works cited will be written in lower case and abbreviated: (Smith, 1990, fig. 5). In case there are several images within the same Figure, they will be referred to as Figure 1A, Figure 1B, etc.

Figure footnote

Each figure must be accompanied by a figure footnote, which must indicate the figure number within the text along with its description. The description must be precise and contain the explanation of all the symbols and abbreviations contained therein. The figure footnotes must be included with the same specifications as the main text, in consecutive order and will be placed at the end of the manuscript, after the works cited in the electronic text file.

 

Tables

1. Tables must be numbered consecutively in the order in which they are mentioned in the text.
2. The size of the tables should be in proportion to the magazine box (17 x 24 cm). If a table is too large, separate it into two or more pages.
3. The number and title will be placed at the top of the table. Column headings should be brief, and units of measurement should be written in parentheses.
4. Any explanation referring to the table may be included as a table footnote, and referred to using lower case letters.
5. References to tables in the text must be capitalized: Table 1 or (Table 1). The reference to tables in other cited works will be written with lower case and abbreviated: (Smith, 1990, tab. 2).

Works cited

The initials of the authors' names must have a space between their initials, for example: “McCauley, S. M.”. Furthermore, in the case of multiple authors, it is recommended to only put “&” before the last author in the references, as follows: “Ahmann, E., Tuttle, L. J., Saviet, M., & Wright, S. D. ”.

 

Place the DOI of the referenced article at the end of the references, as long as you have it. If possible, enter the full address, not just the abbreviation. For example, “http://dx.doi.org/10.18268/BSGM2022v74n3p021122” should be used instead of “DOI: 10.18268/BSGM2022v74n3p021122”.

 

No period should be put after URLS or DOIs.

This information is based on guidelines for certain papers presented at conferences and/or symposiums, in addition to taking into account forms that other specialized journals have previously used for these cases. In contribution types according to the APA 7 manual you can put “Conference Session”, “Paper presentation” and “Poster presentation”; however , in some cases there is only information available from the summaries resulting from these events, so you can put only “Summary/Resumen” in the brackets, depending on the language in which it is cited).
