Report from Belgium
by Julien Denayer / 21st November 2016


* I started a project – writes Julien Denayer – aiming to characterize the biodiversity of corals through the Middle Devonian and the effects of several global events on these faunas. Althought I am still working on Carboniferous corals from Belgium (in collaboration with Eddy Poty), Morocco (with Markus Aretz), Eastern Australia (with Gregg Webb) and Turkey.
** In November 2016 a special volume of Geologica Belgica in homage to Eddy Poty (edited by Markus Aretz and myself) has finally been published. It includes several papers on Devonian and Carboniferous corals and a biography of Eddy Poty (see http://popups.ulg.ac.be/1374-8505/index.php?id=5071).
*** In parallel, I am working on the revision of the Devonian-Carboniferous Boundary, including biostratigraphy of corals accross the boundary.
**** The type and figured materials of the palaeontological collections of the University of Liege are currently being digitalized, the project includes of course all the Devonian and Carboniferous corals published by Eddy Poty and colleagues (numerous references), Jurassic corals published by Maria Lejeune-Carpentier (1935) and Chapuis & Dewalque (1853). The online catalogue is available at http://donum.ulg.ac.be/handle/provenance/fossils. It will be emended during the forthcoming months.

Report from Spain
by Sergio Rodriguez / 21st November 2016


* The research group on Carboniferous of the Universidad Complutense de Madrid - writes Sergio Rodriguez - continues working on Mississippian and Pennsylvanian corals. The members of the group are Sergio Rodríguez, Pedro Cózar and Ismael Coronado, plus external collaborators, Ian D. Somerville (University College, Dublin), Javier Sanz and Silvia Blanco (Universidad de Oviedo) and Felipe González (Universidad de Huelva).
** Our previous funded project "Variations in the biodiversity in relationship with palaeoenvironmental changes in Serpukhovian and Bashkirian from Western Palaeotethys" will be completed in December 2016.
*** Our new funded project has been approved already by the Spanish Ministry of Economy and Competitivity for the period 2017-2020: "Serpukhovian from Western Palaeotethys: climatic changes and their consequences on the palaeodiversity, biostratigraphic, palaeogeographic and environmental aspects".

In the years 2014-2016 our group participated in presentation of the following papers on corals, sponges or reefs:

Report from Poland
by Jerzy Fedorowski / 30th November 2016


*submitted to Acta Geologica Polonica is a following paper:
FEDOROWSKI J. Early Bashkirian Rugosa (Anthozoa) from the Donets Basin (Ukraine). Part 6. The Family Aulophyllidae Dybowski, 1873 (with two Tournaisian taxa in the appendix). [Acta Geologica Polonica, probable publication in 2017]
Seven genera (one new), belonging to four subfamilies, seven named species (six new), four species left in the open nomenclature and two specimens included in the paper as the unnamed Aulophyllidae are described from the lowermost Bashkirian Limestone D5/10 to the lower Bashkirian Limestone F1 strata. A new genus: Voragoaxum and six new species: Dibunophyllum medium, Dibunophylloides paulus, D. similis, D. columnatus, Voragoaxum cavum and Rozkowskia lenta are introduced. A brief illustrated revision of the Tournaisian "Lophophyllum" subtortuosum Gorskyi, 1932 and "Lophophyllum" sp. Gorskyi, 1932, both from the Southern Urals, is included in order to suggest a possible ancestor of Voragoaxum. In Remarks to individual families the suspected relationships within the Family Aulophyllidae is discussed. In the final Considerations a possibility of derivation of the Family Bothrophyllidae from the late representatives of the Subfamily Dibunophyllinae is suggested.

** work in progress is on a following manuscript:
FEDOROWSKI J.. Early Bashkirian Rugosa (Anthozoa) from the Donets Basin (Ukraine). Part. 7. The Family Neokoninckophyllidae Fomichev, 1953 and one new subfamily.
Revision of the family Neokoninckophyllidae, based on my restudy of Fomichev's (1953) collection and supported by peels taken from his specimens allows the emendation of that family as an independent taxon. Thus, its synonymy with the subfamily Dibunophyllinae Hill (1981) is rejected. The new subfamily, represented by three species identified so far, bears several characters in common with the lithostrotionid subfamily Diphyphyllinae, except for being represented by solitary corals.


Report from the USA
by George Stanley Jr / 30th November 2016


* My research focuses on early Mesozoic reefs, the evolution of photosymbiosis and taxonomy of scleractinian corals. For Mesozoic reefs, a study with a former doctoral student, Montana Hodges, addresses the end-Triassic mass extinction and an analysis of the Early Jurassic recovery (Hodges and Stanley 2016). Field work has focused on western North America in Alaska, USA (Nevada), and Mexico. We published a brief report on Early Jurassic corals from the well-known T/J boundary site at New York Canyon, Nevada (Hodges and Stanley 2015). These corals along with other examples from south-central Alaska and Sonora, Mexico are yielding new information on the nature of the recovery in North America and work continues on both dating and analysis of the corals and associated fauna.

** Last year I published collaborative research in Japan on Late Triassic corals from Japan (Stanley and Onoue 2015). This taxonomic work on rare scleractinian corals from the Sambosan Tectonic Belt, revealed previously unrealized diversity and helped test hypotheses on the paleogeography of Carnian and Norian reef corals from tropical locations in western Panthalassa. Results emphasized the diversity and a degree of isolation from coeval corals living in the former Tethys and eastern Panthalassa.

*** I served as co-editor for a book contribution dealing with coral reefs at the crossroads (Hubbard et al 2016). The meaning of this volume's title is that modern reefs stand at the threshold of an important crossroad. We can take the straight path in the business as usual scenario, likely leading to reef collapse, or take a turn to try to save our important marine resource. The 12 chapters in this book contain contributions from well-known reef specialists. They illustrate the multifarious challenges facing reef science and explore the fossil record in order to better understand modern reefs. Among these chapters are my two co-authored contributions with Jere Lipps, one on photosymbiosis in past and present reefs and the other emphasizing evolutionary trends in reefs through time.

Report from Australia
by Ross McLean / 5th December 2016


Here is some update information on my recent coral activities for our Newsletter;
also please note my current e-mail address for all future correspondence: rossmclean48@bigpond.com.

With the support of my affiliation with the University of Wollongong as an Honorary Principal Fellow, I have continued working on Silurian and Devonian rugosans since returning to Australia. Current projects include Middle Devonian cystiphyllids from western Canada, Lower Silurian rugosans from central western NSW, and revision of Australian Lower Devonian species previously assigned to Phillipsastrea (with Tony Wright).

Recent publications:

McLEAN R. A. 2014. Solitary disphyllid corals from the Frasnian (Upper Devonian) of western Canada. Palaeontographica Canadiana 34, 123 pp.

McLEAN R. A. 2016. (manuscript submitted 2016) Fasciphyllid and spongophyllid rugose corals from the Middle Devonian of western Canada.

I also have a question – writes Ross - are there any plans for a future Fossil Cnidaria meeting? I haven't seen any information on the last one - did it actually occur?
