Ordovician News, volume 38 for 2020 (distributed April 2021) Copyright © IUGS 2021 1 CHAIRMAN'S MESSAGE This is my first message as chairman of the ‘Ordovician Subcommission’ because this is the first ‘Ordovician News’ issue with me in this role. Last year I should have taken over the job from the previous chair, Andrei Dronov, during the official meeting of the International Commission on Stratigraphy (ICS) at the 36th International Geological Congress (IGC) at New Delhi, India (early March, 2020), but the organisers in India cancelled the Congress in the last minute. This was before the global outbreak of the covid-19 pandemic, but already too late to stop the very numerous Chinese delegates getting to New Delhi in March 2020. Postponed a few times, initially to November 2020, the IGC still did not take place (and at the time of the writing of these lines is re-scheduled for August 2021), but the IUGS and the ICS had to advance, and the new Ordovician Subcommission with the new executive took over somewhat virtually during July and August 2020. Now, I will not go to the 36th International Geological Congress, if ever it will take place. Many participants (including me), lost a lot of money, with air tickets and hotel rooms being booked, and not always being able to be cancelled, and the refund policy of the organisers being somewhat disorganized and extremely late. Well, that was 2020. We all have our (bad) experiences of that year, that will be remembered, by all of us, for one reason or another, but certainly it will be in our memories in the next decades. And 2021 looks very similar so far… The composition of the new Subcommission, i.e. the Executive and the Voting (Titular) Members is published in the present issue. The changes have been announced in the last issue of Ordovician News (n°37) in the chairman’s message by Andrei Dronov. The list of the former Voting Members (2016–2020) was published in the last four issues of Ordovician News. For the next years (2020–2024), we have a new Subcommission, with a slightly higher number of Members (+3), more female Members (+4) totaling now seven women, and covering almost all disciplines, and all (palaeo-) continents. The new Subcommission came together a few weeks ago for the first time. The covid-19 pandemic forced us to meet online, and this actually allowed us to have a first meeting with ALL voting members. This is extraordinary ! Probably never in the long existence of the Subcommission have all voting members come together at the same time. Internet (and covid- 19) made this possible. You can find a short report about this meeting in this newsletter. There will be surely more meetings with this format in future ! The International Geoscience Programmes (IGCP) also suffered from the covid-19. All IGCP meetings have been cancelled in 2020 (except for a single IGCP project, n°668, that organized its annual meeting before the global pandemic), and in 2021 it very much looks the same. IGCP 653 (The onset of the Great Ordovician Biodiversification Event) was running from 2016 to 2020 (see reports of meetings in the previous issues of Ordovician News), and was expected to be on extended term (OET) in 2021, with several meetings, including the main annual meetings in Copenhagen in September 2020 and in Lille in September 2021. The Copenhagen meeting was cancelled on-site, but was maintained online. Although (similarly to the virtual meeting of the voting members) the Copenhagen congress was ‘only’ online, it can be considered as a huge success. Instead of having the usual 50 to 100 scientists, present physically in a lecture hall, and during an excursion, there were over 200 participants registered from all over the world, listening to the online keynote lectures and talks, allowing 2 many to participate, when intercontinental flights were not possible, and for many scientists were, and will be, not affordable. You can read a report on the meeting in this issue. Many thanks to Chris Rasmussen, Alycia Stigall and all others who helped in the organisation to make this major Ordovician congress in Copenhagen possible ! The 2021 annual meeting in Lille in September will hopefully be similar. Again, the covid- 19 pandemic will not allow us to keep this meeting on-site, and certainly not the organisation of the field trips in Belgium and in the (post-Brexit) UK. As the Copenhagen meeting, the Lille meeting will take place, at the initial dates, but only online. Please, look out for the information about this meeting in this issue of Ordovician News. However, due to a large demand, the excursions will be maintained, and are now postponed to spring 2022. The pre- and post-congress excursions will take place before and after the indoor sessions at Lille, scheduled May 30th–June 1st, 2022. The First Circular is presented in this issue. The meeting will no longer run under the flag of IGCP 653 (that will be definitively over), but under that of IGCP 735. IGCP 735 is indeed the new International Geoscience Programme dedicated to the Ordovician. It was accepted earlier this year by the UNESCO/IGCP. Congratulations to the eight co-leaders. The full title of IGCP 735 is ‘Rocks and the Rise of Ordovician Life (Rocks n'ROL). Filling knowledge gaps in the Early Palaeozoic Biodiversification’ and it will run from 2021 to 2025. The eight leaders (including six female scientist, and half of the leaders working in ‘developing’ countries) propose a very exciting programme for the next five years (2021–2025). You can find further details in this issue. This IGCP is also strongly linked to the Ordovician Subcommission, with four co-leaders being actually Voting Members of our Subcommission. In addition to the meetings related directly to the IGCP’s, there are a few other meetings that should be also postponed, and that are also on our agenda. The Baltic Stratigraphic Congress was scheduled in Saint Petersburg in September 2020, and is currently postponed. Similarly, we are looking forward to the official inauguration of the new ASSP for the base of the Ordovician System in the Xiaoyangqiao section at Dayangcha, North China, ratified in 2019 by the Ordovician Subcommission. The ceremony was scheduled in May 2020, but is currently also postponed. Among the other major events in the next years, we can announce the main annual meeting of IGCP 735 in Marrakech, Morocco, in October, 2022, and our next Congress on the Ordovician System in Tartu, Estonia, in 2023 (see first announcement in Ordovician News n°37 and further information in this issue n° 38). In the last issues of Ordovician News you may have seen the announcement of a publication on a ‘Global Synthesis on the Ordovician System’ initiated almost ten years ago. One of the tasks of the current Executive of the Subcommission is to move forward with this project, and to finally see the publication of this book series, hopefully before the next Ordovician Congress in Estonia.

    From the Ordovician (Darriwillian) of Morocco

    Palaeogeographic implications of a new iocrinid crinoid (Disparida) from the Ordovician (Darriwillian) of Morocco Samuel Zamora1, Imran A. Rahman2 and William I. Ausich3 1 Instituto Geologico´ y Minero de Espana,˜ Zaragoza, Spain 2 School of Earth Sciences, University of Bristol, Bristol, United Kingdom 3 School of Earth Sciences, Ohio State University, Columbus, OH, United States ABSTRACT Complete, articulated crinoids from the Ordovician peri-Gondwanan margin are rare. Here, we describe a new species, Iocrinus africanus sp. nov., from the Darriwilian-age Taddrist Formation of Morocco. The anatomy of this species was studied using a combination of traditional palaeontological methods and non-destructive X-ray micro-tomography (micro-CT). This revealed critical features of the column, distal arms, and aboral cup, which were hidden in the surrounding rock and would have been inaccessible without the application of micro-CT. Iocrinus africanus sp. nov. is characterized by the presence of seven to thirteen tertibrachials, three in-line bifurcations per ray, and an anal sac that is predominantly unplated or very lightly plated. Iocrinus is a common genus in North America (Laurentia) and has also been reported from the United Kingdom (Avalonia) and Oman (middle east Gondwana). Together with Merocrinus, it represents one of the few geographically widespread crinoids during the Ordovician and serves to demonstrate that faunal exchanges between Laurentia and Gondwana occurred at this time. This study highlights the advantages of using both conventional

( Palaeontologist, National 1J1usem·n, JJ:[elboiirne) and Professor TV. N. Benson, B.A., D.Sc. (University of Otago, Dunedin, New Zealcind.) The Australian graptolite fauna is probably the most complete in the world, certainly in regard to its Ordovician components, a fact clearly appreciated by McCoy. He had ready for the press descriptions and figures of most of the species afterwards described in J amcs Hall's J\fonograph published iu 1865, which may be regarded as the basis of systematic graptolite research, when he received from Hall a proof of his fignres. McCoy immediately conceded him priority and adopted his specific names. Had Hall delayed sending his proof, McCoy wonld certainly have pnblisl1ed his figures and descriptions and his name would have been just as pl'ominent in the literature of graptoliies as Hall's. Com­ menting on "Graptolitcs (Didymograpsus) frutieosus (Hall sp.)," l\IcCoy snys, "this is the first Victorian gmptolitc I ever smv, and, as it was then a new species, I had named it in my .MSS. after J\fr.

  • Chapter 2 Paleozoic Stratigraphy of the Grand Canyon

    Chapter 2 Paleozoic Stratigraphy of the Grand Canyon

    CHAPTER 2 PALEOZOIC STRATIGRAPHY OF THE GRAND CANYON PAIGE KERCHER INTRODUCTION The Paleozoic Era of the Phanerozoic Eon is defined as the time between 542 and 251 million years before the present (ICS 2010). The Paleozoic Era began with the evolution of most major animal phyla present today, sparked by the novel adaptation of skeletal hard parts. Organisms continued to diversify throughout the Paleozoic into increasingly adaptive and complex life forms, including the first vertebrates, terrestrial plants and animals, forests and seed plants, reptiles, and flying insects. Vast coal swamps covered much of mid- to low-latitude continental environments in the late Paleozoic as the supercontinent Pangaea began to amalgamate. The hardiest taxa survived the multiple global glaciations and mass extinctions that have come to define major time boundaries of this era. Paleozoic North America existed primarily at mid to low latitudes and experienced multiple major orogenies and continental collisions. For much of the Paleozoic, North America’s southwestern margin ran through Nevada and Arizona – California did not yet exist (Appendix B). The flat-lying Paleozoic rocks of the Grand Canyon, though incomplete, form a record of a continental margin repeatedly inundated and vacated by shallow seas (Appendix A). IMPORTANT STRATIGRAPHIC PRINCIPLES AND CONCEPTS • Principle of Original Horizontality – In most cases, depositional processes produce flat-lying sedimentary layers. Notable exceptions include blanketing ash sheets, and cross-stratification developed on sloped surfaces. • Principle of Superposition – In an undisturbed sequence, older strata lie below younger strata; a package of sedimentary layers youngs upward. • Principle of Lateral Continuity – A layer of sediment extends laterally in all directions until it naturally pinches out or abuts the walls of its confining basin.

    Paleobiology, 45(2), 2019, pp. 221–234 DOI: 10.1017/pab.2019.4 Dissecting the paleocontinental and paleoenvironmental dynamics of the great Ordovician biodiversification Franziska Franeck and Lee Hsiang Liow Abstract.—The Ordovician was a time of drastic biological and geological change. Previous work has suggested that there was a dramatic increase in global diversity during this time, but also has indicated that regional dynamics and dynamics in specific environments might have been different. Here, we contrast two paleocontinents that have different geological histories through the Ordovician, namely Laurentia and Baltica. The first was situated close to the equator throughout the whole Ordovician, while the latter has traversed tens of latitudes during the same time. We predict that Baltica, which was under long-term environmental change, would show greater average and interval-to-interval origination and extinction rates than Laurentia. In addition, we are interested in the role of the environment in which taxa originated, specifically, the patterns of onshore–offshore dynamics of diversification, where onshore and offshore areas represent high-energy and low-energy environments, respectively. Here, we predict that high-energy environments might be more conducive for originations. Our new analyses show that the global Ordovician spike in genus richness from the Dapingian to the Darriwilian Stage resulted from a very high origination rate at the Dapingian/Darriwilian boundary, while the extinction rate remained low. We found substantial interval-to-interval variation in the origin- ation and extinction rates in Baltica and Laurentia, but the probabilities of origination and extinction are somewhat higher in Baltica than Laurentia. Onshore and offshore areas have largely indistinguishable origination and extinction rates, in contradiction to our predictions.

An easy-to-navigate pocket guide to the Meeting is also available to delegates. Venue The Annual Meeting will take place in the faculties of Philosophy and Philology on the Blasco Ibañez Campus of the University of Valencia. The Symposium will take place in the Salon Actos Manuel Sanchis Guarner in the Faculty of Philology. The main meeting will take place in this and a nearby lecture theatre (Salon Actos, Faculty of Philosophy). There is a Metro stop just a few metres from the campus that connects with the centre of the city in 5-10 minutes (Line 3-Facultats). Alternatively, the campus is a 20-25 minute walk from the ‘old town’. Registration Registration will be possible before and during the Symposium at the entrance to the Salon Actos in the Faculty of Philosophy. During the main meeting the registration desk will continue to be available in the Faculty of Philosophy. Oral Presentations All speakers (apart from the symposium speakers) have been allocated 15 minutes. It is therefore expected that you prepare to speak for no more than 12 minutes to allow time for questions and switching between presenters. We have a number of parallel sessions in nearby lecture theatres so timing will be especially important.
