Sketches of stromatoporoid assemblages visible on weathered rock surfaces.
A–allobiostrome fragment representing a typical clast-supported stromatoporoid accumulation dominated by high-domical and bulbous forms with smooth surfaces and enveloping latilaminae arrangements, and with initial surfaces dominated by initial ...

Enhanced Continental Weathering as a Trigger for the End‐Devonian Hangenberg Crisis
Abstract The Hangenberg Crisis coincided with a large decline of biodiversity and widespread anoxia in the end‐Devonian ocean. Previous research attributed marine anoxia to the spread of deeply‐rooted plants and/or increased volcanism on the continents, but crucial links have not been thoroughly explored. Herein, we propose enhanced weathering as a key

ABSTRACT During the Middle Devonian, reef growth reached an acme, and corals and stromatoporoids colonized depositional niches commonly considered unfavourable for reefal organisms. This paper documents the detailed facies architecture and palaeoecology of a stratigraphically thin (ca 12 m, ‘carpet reef’), lower Givetian reefal body exposed along the ...

Palaeobiology, ecology, and distribution of stromatoporoid faunas in biostromes of the mid-Ludlow of Gotland [PDF]
Six well exposed mid−Ludlow stromatoporoid−dominated reef biostromes in four localities from the Hemse Group in southeastern Gotland, Sweden comprise a stromatoporoid assemblage dominated by four species; Clathrodictyon mohicanum, “Stromatopora” bekkeri,

Allogenic succession in Late Ordovician reefs from southeast China: a response to the Cathaysian orogeny [PDF]
Several Late Ordovician (late Katian) reef complexes are known from the border area of Jiangxi and Zhejiang provinces in southeast China. We studied two coral–stromatoporoid reefs exposed in the Xiazhen Formation at Zhuzhai (Yushan, Jiangxi).

ABSTRACT Bryozoan–stromatolite associations (bryostromatolites) formed conspicuous reef structures throughout the Sheinwoodian (Wenlock) to Ludfordian (Ludlow) stratigraphy on Gotland but have not been described so far. They are mainly composed of encrusting bryozoans forming a complex intergrowth with porostromate and spongiostromate microbes and are ...

The appearance of Rosenella (stromatoporoid sponge) in Baltica: new species from the Pirgu Stage (Katian, Upper Ordovician) of Estonia [PDF]
The Katian Age, part of the Late Ordovician Epoch, was a period of significant stromatoporoid diversification. However, their fossil record is often less continuous, hindering our understanding of their diversity and diversification.

First report of an aulaceratid stromatoporoid from the Ordovician of Baltica [PDF]
The aulaceratid stromatoporoids first appeared in the late Middle Ordovician and had achieved a worldwide distribution in tropical to subtropical shallow-marine environments by the Late Ordovician; however, their presence in Baltica has not been ...

Revisiting the Cupidito unit (Cupido Formation) along peritidal carbonates from northeastern Mexico
Depositional episodes are readily identified along representative localities of the Lower Cretaceous Cupido platform in northeastern Mexico. The basal part of the Cupido Formation exhibits a progradational reef platform that, at the upper limit, is ...
