EXCECUTIVE’S COLUMN
Dear Fellow Carboniferous Researchers, newsletter; and we have decided to send out hard copies again. We hope the difficulties with the Publication date of Newsletter on Carboniferous website can be eliminated during this next fiscal Stratigraphy year. For many years, the Newsletter has been given a XVI International Congress on the Carboniferous July publication date and distributed during July and and Permian August. During the last couple of years, we have found it very difficult to carry on with this tradition The next congress on the Carboniferous and and, as a consequence, have decided to change the Permian will be held on the riverside campus of the publication and distribution dates. After serious University of Western Australia in the beautiful city consideration, we have decided to give the of Perth, Australia from July 3rd-8th, 2011. Please see newsletter a November publication date and get it their website for details and the first circular. printed and distributed during November and www.iccp2011.org. Scientists interested in all December. There are several reasons for making aspects of the Carboniferous and Permian are this change; but the principal one is the difficulty of encouraged to attend and discuss recent advances compiling the newsletter in June and July when it is in understanding one of the most dynamic intervals necessary for the secretary and chairman to take in Earth History. Now is the time to start advantage of the short summer season to do field considering the submission of papers. The last date work in our northern climates. In previous years, we for abstract submission is the 11th of February, 2011 requested our contributors to submit their articles and that date is rapidly approaching. February 11th to the secretary, Markus Aretz, by May 31s; but for is also the last day for the early-bird reduced the future, we would like you to submit your articles registration fees. A preliminary program listing by September 30th. This will give us the month of congress themes will be available in late 2010 and October to prepare the newsletter for printing and the final program will be available in April, 2011. distribution in November. We know it will be expensive to come to the Perth meeting from the northern hemisphere but it will be The other main reason for changing the printing worth coming to interact with friends and date from July to November is to reduce the amount colleagues, attend the meetings, and see some of the of time that task-group chairmen spend on unique geology of Gondwana on the scheduled field preparing progress reports for their groups. We can trips. The Carboniferous and Permian Congress is accomplish this goal to a substantial extent by certainly the most important of all geological making the reporting year for the task groups meeting for SCCS members and it is only held every coincide with the fiscal year (November 1st to four years. October 31st) of our parent organization the International Commission of Stratigraphy. Until the As part of the formal congress program, we plan present, the chairs have had to prepare separate to have a thematic session that will be chaired by progress reports for both the July newsletter and some component of the SCCS executive and tailored the ICS Annual Report, which is due by mid- for our numbers interests - Carboniferous November. In general, we have found substantial Stratotypes, Boundaries, and Global Correlations. In changes need to be made to the task group reports this session, we would like to have the task-group prepared for the July newsletter to make them chairs give progress reports for the boundary their suitable for the Annual report. We want to eliminate team is studying. In addition, we encourage our some of this time-consuming work so that the same task-group members to provide detailed task group reports can be used for both the stratigraphic and paleontological accounts about newsletter and Annual Report. Much of the annual some of the best GSSP candidate sections they are progress made by the task groups is accomplished currently working on. The SCCS will hold a business during the spring and summer field season and it is meeting (of about one hour duration) and we hoped that the new November printing date will still encourage all of the voting members to attend. provide task groups enough time to compile the Depending on conference attendance, the XVI ICCP results of the year’s field activities. could provide a good opportunity for some of our task groups to get together for workshops.

Most JULY 1, 2009 - JUNE 30, 2010 delegates were executive members of ICS subcommissions, with others representing national stratigraphic commissions. Our subcommission was During the last reporting year for the Newsletter well represented; those in attendance were: Markus (July 1, 2009 to June 30, 2010) there were several Aretz, Svetlana Nikolaeva, Barry Richards, Katsumi conferences, field meetings and workshops of Ueno, Wang Xiangdong, and Qi Yuping. What we substantial interest to SCCS members. Some of these consider to be the most important aspects of the meeting such as the Second International Conodont presentations and resulting discussions at the Symposium held in Calgary (July 12th to 17th 2009) meeting in terms of the mandate of the SCCS are and the workshop at the Third International outlined below. Paleontological Congress in London (June 28th to July 3rd, 2010) were mainly of interest to the D/C The Prague meeting was not entirely what the boundary task group. The notes taken at those SCC leadership had expected. We had anticipated st meetings have been incorporated into the task- that days one and four of the meeting (May 31 and rd group report for the D/C boundary working group June 3 ) would overtly focus on what was herein. Perhaps the most significant meetings for necessary to establish an ideal GSSP and what the full subcommission were the field meeting and should be avoided to prevent problems leading to workshop held in Russia in 2009 (I.U.G.S. the re-appraisal or redefinition of a GSSP.

For that you need to carefully study 1 Geological Survey of Canada-Calgary, 3303-33rd St. N.W., Calgary, Alberta, Canada T2L 3A7 and abide by the recommendations laid out by Remane et al. (1996).

It is very biostratigraphic approaches is the only method important that boundary stratotype sections extend available. In subdividing the Cambrian System, well above and below the GSSP as well as across it in Loren Babcock (U.S.A.) noted that fossils can be order that important biostratigraphic and other used for boundary definition but all 10 provisional trends can be clearly observed and documented.

Guide fossils must be illustrated Ediacaran Period (Knoll et al., 2004, 2006). At the and not just named. Another common practice has Prague meeting, Martin Van Krandendonck been to illustrate an ideal specimen of a taxon used (Australia) presented a strong case for further to define a GSSP instead of showing a typical subdivision of the Precambrian into eons, eras and specimen from the GSSP itself. The best practice is periods utilizing GSSPs that reflect global chemical to illustrate the defining taxon from the boundary and climatic events. At the other end of the time level and not just from other levels or localities.

Our less evolutionary appearance of a taxon within a lineage formal manuscripts proposing candidate sections should be used to define a GSSP but the employment for a GSSP can be published without either SCCS or of multiple stratigraphic approaches is invaluable ICS approval.

When a multidisciplinary approach is in a journal such as Palaeoworld, which is broadly used, the methods need to be coordinated and the distributed and will accept relatively long holistic work done at the same general time and at the same articles dealing with a variety of stratigraphic scale.

Perhaps the most at La Serre (the current location of the GSSP) important of these were the Second International indicate the lack of the phylogenetic transition from Conodont Symposium (ICOS 2009) in Calgary, S. praesulcata to S. sulcata (Kaiser, 2009). 3) Alberta Canada from July 12th to 17th 2009, the Because the first appearance (FO) of S. sulcata may International field meeting of the I.U.G.S. not be the best event to define the boundary, other Subcommission on Carboniferous Stratigraphy (11- appropriate lineages particularly in the 19 August, 2009) held in Moscow and the southern protognathodids within the upper part of the Ural Mountains of Russia, and the Third praesulcata Zone require evaluation. However, by International Paleontological Congress (IPC3) held late summer of 2010, the task group is still far from in London, England (June 28th to July 3rd, 2010). its main objective - selecting a new GSSP for the D-C Highlights from these meeting are presented below.

Specialists attending the 2008 by Philip Heckel (former chairman of the SCCS workshop agreed that the D-C boundary can not = Subcommission on Carboniferous Stratigraphy) remain at its present position at La Serre (base of and Thomas Becker (chairman of the SDS = bed 89) and that a new GSSP must be selected either Subcommission on Devonian Stratigraphy) to study lower in the La Serre section or in another section. and resolve the serious problems with the integrity They also decided that the initial problem to resolve of the D-C GSSP. At the time the task group was was the selection of a suitable taxon for boundary established, 10 members were appointed from each definition. Three options were presented: continue subcommission to form the task group (Heckel, use of the S. praesulcata-S. sulcata lineage but find a 2008). A chairman was not appointed, and the SCCS better way to speciate it, select a different conodont executive that replaced the previous officers at the lineage (protognathodids), and use the first 33rd International Geological Congress in Oslo occurrence of a taxon within another fossil group. In during August 2008 decided to wait to see what conjunction with the workshop, task-group direction the task group would take and if a members and other conference delegates visited chairman was necessary before selecting one. three D-C boundary sections in the Rocky Mountain During 2009, it became apparent that problems Front Ranges west of Calgary (Richards et al., 2009). with the GSSP would not be resolved without major On August 14th, during the southern Uralian taxonomic and lithostratigraphic analyses requiring component of the SCCS field meeting in Russia (see strong direction and leadership from a chairman.

In addition to these ESTABLISH THE MOSCOVIAN– Russian organizers, Qi Yuping and Katsumi Ueno participated in this field meeting from the task KASIMOVIAN AND KASIMOVIAN– group. The visited sections that are intimately GZHELIAN BOUNDARIES related to our task group activity are the Domodedovo and Gzhel sections in the Moscow Katsumi Ueno and Task Group Basin and the Usolka and Dalniy Tyulkas sections in the southern Urals. The Afanasievo section in the Department of Earth System Science, Fukuoka University, “Voskresenskcement” Quarry in the southeastern Fukuoka 814-0180, JAPAN part of the Moscow Basin, which is now regarded as the neostratotype of the regional Kasimovian stage General activities (Goreva et al., 2009a), was originally planned to be In August 2009, the I.U.G.S.

Urals of Russia, in order to examine several In the Moscow Basin, we examined the upper historical type sections and proposed and potential Moscovian-basal Kasimovian succession of the GSSPs of the Russian Carboniferous. This meeting Domodedovo section and the lower Gzhelian was organized by colleagues mainly from Moscow succession of the classic Gzhel section. The former is and Ufa, including our task group members the neostratotype of the regional Moscovian stage Alexander S. Alekseev, Natalia V.

These features demonstrate the former is considered as the probable ancestor of strong genetic control of high-frequency eustatic the latter (Heckel et al., 2008). Overall, the Dalniy sea-level changes over the sedimentation of these Tyulkas (composite) sections seem to be promising strata. Fossils, particularly conodonts, fusulines, candidates for both Moscovian-Kasimovian and corals, and brachiopods are abundant, and their Kasimovian-Gzhelian boundary stratotypes. Further stratigraphic occurrences have been documented in detailed investigation by these Russian colleagues is detail. When considering the availability of these underway. sections as GSSP candidates for the bases of relevant Progress reports from members stages, however, the main problem would be the presence of frequent sedimentary gaps. South China. James E. Barrick and Qi Yuping collaborated in examining existing and new In the southern Urals, the Usolka section was collections of conodonts from the Nashui section of visited to investigate the usefulness of this section southern Guizhou, China (Wang and Qi, 2003). as a base-Gzhelian GSSP candidate. To date, this is Review of these specimens allows better the only section that has been proposed formally as recognition of the approximate positions of the a potential candidate for GSSP to define the base of Moscovian-Kasimovian and Kasimovian-Gzhelian the Gzhelian stage (Chernykh et al., 2006). Later, stage boundaries. In this section, latest Moscovian Davydov et al.

The base of the Gzhelian transition in this section. Unfortunately, Kasimovian is marked by the disappearance of the Kasimovian-Gzhelian boundary interval of the Swadelina and appearance of Idiognathodus Usolka section is now largely concealed by soil and morphotypes of the I. swadei-I. sagittalis group, vegetation.

In MALO-NIKOLAEVKA SECTION the 1950s, it was placed at the base of Limestone K1, and later at the base of Limestone K3 (Kireeva, Tamara I.

In this section, we examined thick interval is poorly exposed and contains 1 2 eight limestone beds; they are Limestones I2, I2 , I2 , intervals of sporadically exposed thin-bedded I3, I4, K1, K2, and K3 (Figure 2). medium-grained sandstone. Limestone I3 is dark- gray bioclastic packstone with crinoidal debris and
fragments of Beresella, and found only as some loose blocks. About 45 m above this limestone, Limestone I4 is exposed, forming a low but continuous ridge along its strike. It is composed mainly of fine- grained bioclastic packstone, but in some levels, large biomorphs such as phylloid algae, tabulata (auloporids), and small solitary corals are observed.
Limestone K1, the first limestone bed of the 5 C2 (K) suite, is well exposed along a small creek to the west of the highway, forming a continuous prominent ridge. It is an about 90 cm-thick limestone with more or less nodular appearance and consists mainly of bioclast-poor muddy limestone. This limestone is then overlain by dark- gray shale and persistent, thick, coarse-grained brown sandstone, which is called the “Tobacco” sandstone (Aizenverg et al., 1975). It is a widely- distributed fluvial sandstone unit and is regarded as a good marker bed for recognizing the K1-K2 stratigraphic interval in the eastern part of the Donets Basin (Aizenverg et al., 1975; Izart et al., 1996). The next limestone - K2 consists of coarse- grained, dark-gray bioclastic packstone and grainstone with abundant debris of crinoids, calcareous algae, brachiopods, and foraminifers. The uppermost limestone in the Malo-Nikolaevka section is Limestone K3 and is exposed stratigraphically about 60 m above Limestone K2. It is dark-gray and nodular, and is associated with a B coal seam (k2 ) just below it. This limestone interval is dominated by bioclastic wackestone. Biostratigraphy Conodonts More than five hundred conodont elements were 4 recovered from all the limestones of the C2 (I) suite 5 and the lowermost part of the C2 (K) suite.

The last occurrence of their in the Malo-Nikolaevka section as well as in the ancestor Declinognathodus noduliferus noduliferus, a Zolotaya Valley section – the other known section common Bashkirian species and an index-species covering the Bashkirian-Moscovian boundary for the mid-Carboniferous boundary (Brenckle et al., interval in the Donets Basin, where this lineage was 1997), was recorded in the lowest limestone of the introduced for the first time (Nemirovskaya, 1990; Malo-Nikolaevka section - Limestone I2 where it Nemyrovska, 1999, Nemyrovska et al., 1999). dominates. The first appearance datum (FAD) of its Unfortunately, the other potential marker conodont direct descendant Declinognathodus marginodosus lineage for the Bashkirian-Moscovian boundary, was registered at the same level – namely which is Idiognathoides sulcatus–Idiognathoides Limestone I2. This species is common in every postsulcatus and was discovered in the Zolotaya 4 limestone of the C2 (I) suite, and it becomes Valley section and in the Pashennaya section to the dominant upwards the section in Limestones K2 and south of Lugansk (Nemyrovska, 2005), was not K3. The FAD of its descendant Declinognathodus proved in the Malo-Nikolaevka section as Id. donetzianus was recorded in this section at the top postsulcatus was not found there. Both lineages of Limestone K1. were recovered in different regions and therefore The genus Idiognathodus known from strata as were proposed as potential markers to define the old as mid-Bashkirian is represented in this section Bashkirian-Moscovian boundary (Groves and Task by several species, such as I. aljutovensis I. volgensis, Group, 2004; Nemyrovska, 2005, 2006 a, b).

Fusulines Bashkirian-Moscovian boundary of the Malo- Sixteen fusuline taxa were identified from the Nikolaevka section Malo-Nikolaevka section (Figure 2). Of them, several Originally, three potential evolutionary events small lenticular species such as Eostaffella were suggested in conodonts to define the grozdilovae, E. rjasanensis, and Mediocris (M.) Bashkirian-Moscovian boundary (Groves and Task breviscula are found throughout the succession, Group, 2004). Two of them were proposed based on while others (Novella sp. and Pseudonovella data from the Donets Basin. The first is the carbonica) are restricted in some particular levels. evolutionary first appearance of conodont Ozawainella is represented by several species, Declinognathodus donetzianus, which derived from including O. pararhomboidalis and O alchevskiensis. Decl. marginodosus. The second event is They are generally less common in samples from characterized by the first appearance of the section. Neostaffella also occurs throughout the Idiognathoides postsulcatus, which derived from Id. succession although they are not very abundant sulcatus. Both lineages are represented by the latest except in Limestone K2. Moreover, specimens of species of the respective genera: Declinognathodus 4 Neostaffella from the C2 (I) suite are generally and Idiognathoides, which dominated during 5 small, but those from the C2 (K) suite, particularly Bashkirian time. The members of these lineages are Neostaffella (N.) vozhgalica from Limestone K2, are known in many regions all over the world. However relatively large and have shells with 5.5 to 7.5 the lineages themselves are not very common. In volutions. Specimens of Profusulinella are found in many sections, we have one descendant but without several limestone levels, but they are not identified ancestor, and vice versa. The third event is related in species level in this study. with the appearance of late morphotype of The most important and conspicuous lineage in Neognathodus nataliae. However, it was considered the fusuline fauna of the Malo-Nikolaevka section is as an unsuitable candidate for making the base of represented by Verella and Eofusulina (Figure 4). Of the Moscovian because of its restricted distribution 4 them, Verella sp. is restricted in the C2 (I) Suite and and the uncertainty with the taxonomic concepts 1 2 is found from Limestones I2, I2 , I2 , and I3. The first involved in the transition from early to late Eofusulina is registered in Limestone K1. Due to morphotypes (Groves and Task Group, 2005). insufficiency of available materials, however, it is The fourth lineage was later proposed by Qi et al. not identified in species level in this study. In (2007) based mainly on data from the Nashui Limestone K2, Eofusulina triangula and E. section of South China (Groves and Task Group, trianguliformis are dominant, and the former 2007).

In Groves and Task Group (2008) noted that this respect, Groves (1988) also clearly demonstrated evolutionary relationships among Diplo. that the first Neostaffella is observed in the ellesmerensis and other species in the genus are not Tashastinsky Horizon (lower part of the upper adequately known and most recovered specimens of Bashkirian) in the stratotype section of the this species seem to be juveniles, with larger, adult Bashkirian in the South Urals. These lines of evidence specimens being extremely rare. Although Diplo. suggest that the evolutionary appearance of ellesmerensis was reported elsewhere in the Donets Neostaffella from Pseudostaffella took place Basin (Nemyrovska, 1999), both species have not sometimes within the Late Bashkirian, much below been found in the Malo-Nikolaevka section. the existing Bashkirian-Moscovian boundary. Nevertheless, large neostaffellids like as Neostaffella In the Malo-Nikolaevka section, the first (N.) vozhgalica certainly start occurring from conodont lineage includes three members, forming Limestone K . an evolutionary series of Declinognathodus 1 noduliferus–Decl. marginodosus–Decl. donetzianus At the moment, the fourth Verella–Eofusulina (Figure 3).

This species looks which was proposed as a potential global marker for advanced in the relevant genus in its relatively the base of the Moscovian stage, was reported strongly and regularly fluted septa in axial regions, earlier in Limestone K2 of the Zolotaya Valley and is somewhat similar to V. transiens, which was section (Nemyrovska, 1999), but it was recently originally reported by van Ginkel and Villa (in van found in Limestone K1 of both the Zolotaya Valley Ginkel, 1987) from the Lena Formation of and Malo-Nikolaevka sections. Thus its evolutionary northwestern Spain and is known to occur from a first appearance is proved by its occurrence in the stratigraphic interval just below that containing true Malo-Nikolaevka section. Eofusulina species. In contrast, Limestone K1 yields the first Eofusulina (E. sp.: Figure 4-2). This species The second lineage Idiognathoides sulcatus–Id. somewhat resembles E. plicata, which was originally postsulcatus was recorded in the Donets Basin and proposed by Rumyantseva (1962) as a species of partly in the other regions. The FAD of Id. Verella based on materials from Central Kyzylkum of postsulcatus was registered earlier in Donbas in Uzbekistan, but should be better subsumed in the Limestone K of the Zolotaya Valley section and in 2 genus Eofusulina as it has a slightly larger shell and Limestone K of the Karaguz section (Nemyrovska, 3 more regularly and strongly fluted septa than typical 1999). This species is most common in the overlying species in Verella. Thus, E. plicata would be regarded limestones of the C 5(K) suite. It was not found in 2 as one of the first representatives of the genus.

Tuning of these fourth- order sequences to the long eccentricity cycle allows calibration of the biostratigraphic record at a resolution of 100 ka.

Figure 3. Lithostratigraphy and sequence stratigraphy through the Kasimovian-Gzhelian succession of the central exposed Donets Basin (modified from Izart et al.). The long eccentricity cycle tuning of fourth-order sequences derived for the Moscovian succession is extrapolated upward to the Carboniferous-Permian boundary constrained at 298.7 Ma in the Usolka parastratotype section of the Urals. High frequency and fourth-order sequences of the Kasimovian and early Gzhelian are well developed, lending more confidence to the cyclostratigraphic calibration. Although cyclicity becomes more ambiguous in the increasingly continental upper Gzhelian succession, only modest reinterpretation of Izart et al.’s fourth-order sequences as higher-frequency cycles is necessary to align the base of the Asselian in the Donets Basin with the radiometric constraint from the Urals

CONTRIBUTIONS TO THE NEWSLETTER
The Newsletter on Carboniferous Stratigraphy is published annually (in November) by SCCS. It is composed of written contributions from its members and provides a forum for short, relevant articles such as: * reports on work in progress and / or reports on activities in your work place * news items, conference notices, new publications, reviews, letters, comments * graphics suitable for black and white publication. Contributions for each issue of the Carboniferous Newsletter should be timed to reach the Editor before 30 September in the year of publication. It is best to submit manuscripts as attachments to Email messages. Except for very short news items, please send messages and manuscripts to my Email address. Manuscripts may also be sent to the address below on CD prepared with Microsoft Word (preferred) or WordPerfect but any common word processing software or plain ASCII text file can usually be accommodated. Word processing files should have no personalized fonts or other code. Maps and other illustrations are acceptable in tif, jpeg, eps, or bitmap format. If only hard copies are sent, these must be camera-ready, i.e., clean copies, ready for publication. Typewritten contributions may be submitted by mail as clean paper copies; these must arrive well ahead of the deadline, as they require greater processing time.
Please send contributions by email or surface mail to:
