    Abstract. The biostratigraphical data on the East Baltic Silurian chitinozoans are summarized. Based on the study of nine East Baltic drill cores, 28 regional chitinozoan zonal units, including 26 biozones and 2 interzones, are briefly characterized. In comparison with earlier publications, the Silurian chitinozoan biozonation chart is essentially updated, some biozonal units are added, some. SERVAIS T. - The Ordovician acritarch Frankea.

ISBN: OCLC Number: Notes: Spine title: Acritarch and chitinozoan research. Description: pages: illustrations, maps ; 25 cm. A chitinozoan vesicle consists in general of a chamber connected by the shoulder and flexure with the neck and end aperture. Figure 1 shows the basic morphologic characteristics and chamber shapes that are encountered in most vesicles: around the aperture a collarette, a fragile membranous continuation of the vesicle wall can be found.

A formal Ordovician–Silurian chitinozoan biozonation for western Gondwana is proposed. This palaeogeographic province includes South America, and was located in medium to high latitudes during Ordovician and Silurian times. Ordovician chitinozoans are known from northern Argentina, southern Bolivia, and by: Veryhachium Deunfforiginally described from the Ordovician of western France, is one of the most frequently recorded acritarch genera.

Over species and subspecies, from the Cambrian to. Talks and posters were presented during the three days of the congress, either in the general sessions or in the subcommission symposia dedicated to acritarch/chitinozoan and spore/pollen research.

All contributions from the Lille meeting were published as abstracts at the time of the congress (Raevskaya and Servais, ).Cited by: 5.

Lower to Middle Ordovician acritarchs from China have been described in more than 25 publications. Most of the contributions deal with the relatively short time interval represented by the lower to middle Arenigian Didymograptus deflexus and Azygograptus suecicus graptolite biozones in the lower part of the Dawan and Meitan formations from the Yangtze Platform.

Richard A. Waters's 32 research works with citations and 4, reads, including: Gauging the impact of glacioeustasy on a mid-latitude early Silurian basin margin, mid Wales, UK. The acritarch assemblage occurring in the upper part of the Lierneux Member (Jalhay Formation, Salm Group, Stavelot Inlier, Belgium) has recently been attributed to the messaoudensis-trifidum.

Acritarch and chitinozoan assemblages from the Suri and Molles formations share several species with coeval cold water peri-Gondwana assemblages. They also present species reported from South China and Australia suggesting more temperate water conditions, at an intermediate latitude.

Veryhachium is an acritarch genus that occurs commonly in marine shales from the Ordovician to the Tertiary, with morphologically closely related forms appearing in the Cambrian. Its simple morphology together with its long stratigraphic range and abundance makes it attractive as a potential thermal maturity indicator.

This short review on chitinozoan research, from the first discovery in to the present day, clearly shows that Florentin Paris was one of the major contributors of chitinozoan studies in the last part of the 20th and the beginning of the 21st centuries. the substantial work on the associated acritarch floras and chitinozoan faunas in relation to oil and gas exploration (e.g.

Borehole drilled in the northern area of the Arkhangelsk Oblast penetrated through the Paleozoic sedimentary block isolated in the Vendian thick sequence. A diverse acritarch assemblage has been established within the depth interval of – m.

The assemblage comprises more than 70 taxa, including species characteristic of the boundary interval between the Volkhov and Kunda.

Chitinozoa (singular: chitinozoan, plural: chitinozoans) are a taxon of flask-shaped, organic walled marine microfossils produced by an as yet unknown animal.

Common from the Ordovician to Devonian periods (i.e. the mid-Paleozoic), the millimetre-scale organisms are abundant in almost all types of marine sediment across the globe.

This wide distribution, and their rapid pace of evolution. The used time-lines MFS (maximum flooding surfaces) were defined from the type section and based on maxima of deepening in the basin and on correlated acritarch, chitinozoan, and spore assemblages (Moron in Durand, ).

Note the development of a regressive phase with settling of a lowstand delta in the northern part. were investigated which represent acritarch specimens, chitinozoan specimens, scolecodont specimens and 38 specimens of graptolites remains (Table 1).

A total of 23 acritarch species (15 genera) and 29 chitinozoan species (15 genera) were identified (Fig. 2; Plates I. Tremadocian acritarch assemblage with Arenigian chitinozoan ones, both identified on the same analyzed samples from the Upper Formation (Tg.

The presence of some chitinozoan and acritarch taxa from the Baltic and Laurentia in Gondwanan chitinozoan biozones of the Fazel Abad area suggests the existence of counterclockwise marine currents, which brought planktonic organisms (acritarchs, chitinozoans, and graptolites) from lower latitudes (Baltica) to higher latitudes (North Gondwanan.

Acritarch species that went extinct, essentially did so above datum 6 of the conodont extinction event, i.e., well above the positive shift in our δ 13 C org data (just above datum 2).

Acritarch originations occur throughout the section [Gelsthorpe, ]. The δ 13 C org shift thus seems to be unrelated to acritarch turnover events at species. The session started with talks in more or less stratigraphical order from the Cambrian to the Devonian, dealing with all aspects of acritarch, chitinozoan, prasinophyte and (crypto)spore research.

A very interesting and well-attended session (a4) took place in the afternoon, unfortunately in parallel to the CIMP symposium, on palynomorph wall.Acritarch microfloral succession from the Late Cambrian and Ordovician (early Tremadoc) of Random Island, eastern Newfoundland, and its comparison to coeval microfloras, particularly those of the East European Platform.
