Taphofacies of Lower-Middle Pennsylvanian marine invertebrates from the Monte Alegre and Itaituba formations, part of the outcropped marine sequence of the Tapajós Group (Southern Amazonas Basin, Brazil) – regional palaeoecological models. Journal of South American Earth Sciences, Vol. 70, Issue., Cited by: most part ofth e sectio n. In the up permost part of th e section, in the western part of the qua rry, gastropod s and pelecypods are as freq uent as brachiopods. The profile represents th e Givetian and lowermost Frasnian up to the Lower asymmetricus Zone. Conodonts were found in samples K/RD-I to 4.
The brachiopods occur mainly in the skeletal and silty limestone of the Kuldiga Formation within the lower half of the Porkuni Stage. Few brachiopods are known from the sandy or oolitic limestone of the Saldus Formation in the upper part of the stage. Due to excellent preservation some brachiopod species (e.g., Cliftonia psittacina and Cited by: 7. found which will help with stratigraphy and pinpoint the age of the rock. DEPTH CONTROL ON FAUNA Work done by Fred Ziegler in the early s included collecting brachiopods from mainly the southern part of the Welsh Borderlands, the Malverns, etc., and he persuaded another student, Robin Cocks, to collect Llandovery brachiopods.

Bulletin of the British Museum (Natural History), Geol – International Subcommission on Stratigraphic Classification The Campanian-Maastrichtian boundary sequence in Norfolk is very poorly exposed and is condensed.
However, the existence of a highly diverse micromorphic brachiopod fauna allows correlation with more complete and well-exposed sections elsewhere in northwest Europe, especially northwest Germany and. New data on the stratigraphy and faunal assemblages of the Lower Silurian of the Chingiz region are presented.
Owing to the discovery of Ruddanian brachiopods in the basal Alpeis Formation, the position of the Ordovician-Silurian boundary has been revised.
The stratigraphic range of the Alpeis Formation has been revised to correspond to the range of the Alpeis Horizon in the stratotype and is Cited by: 2.

The occurrence of Heptabronteus is of significance, as the genus has been regarded as a junior synonym of Eokosovopeltis which is known from Caradoc (middle Katian) strata of Australia (Edgecombe et al.

Here, we describe three genera of lingulid brachiopods from the muddy siltstone of the Cambrian Series 2, unnamed Stage 4 Shipai Formation (Zhang and Hua, ), showing comparable preservation with those from Chengjiang fauna and Guanshan fauna recovered in eastern Yunnan province of China (Zhang et al., b, Zhang et al., ).This is the first report of Cambrian brachiopods with Cited by: scribes the stratigraphy and faunas of the high Caradoc Nakholmen Formation (Upper Chas mops Shale of previous authors).

The site is a low-relief area underlain by Middle Chalk and the oldest part of the Upper Chalk in a region where the stratigraphy of the Chalk was poorly known prior to the investigation.

New chitinozoan data are presented from the classical section along the Onny River in the type Caradoc area, and from the deeper-water sections in the Shelve area, including the former British candidate GSSP for the base of the Upper Ordovician Series.
The rich and well-preserved chitinozoan fauna of the Onny River has been a standard for 40 years, but new data revise some of the identiﬁcations.

The analysis of the taxonomic composition and distribution of acrotretids (Brachiopoda) in the Middle Cambrian and early Late Cambrian shows that, in the later half of the Cambrian, the order Acrotretida was the most abundant brachiopod order and many of its representatives were cosmopolites.
