A new species, Erbenoceras erbeni, is erected for specimens from *< Lower Nevada Limestone in the Cortez Mountains and is thought to be of Emsian age. -im higher in the Nevada Limestone in the southern Roberts Mountains, but below the »3-known Siringocephahts-hezting level, occurs Cabrieroceras aff. crispiforme, which would -Tear to indicate a basal Givetian horizon. A poorly preserved lmitoceras is recorded ~tn the Pilot Shale in the Pahranagat Range. All these three genera are recorded from «Tada for the first time. Comments are made on the palaeogeographic significance of the Tjrrence of these distinctively European forms in the western United States. Introduction Through the kindness of Dr. J. G.

Message from the New Chairman
Subcommission on Devonian Stratigraphy Newsletter No. 21 April, 2005 MESSAGE FROM THE NEW CHAIRMAN Dear SDS Members: This new Newsletter gives me the pleasant opportunity to thank you for your confidence which should allow me to lead our Devonian Subcommission successfully through the next four years until the next International Geological Congress in Norway. Ahmed El Hassani, as Vice-Chairman, and John Marshall, as our new Secretary, will assist and help me. As it has been our habit in the past, our outgoing chairman, Pierre Bultynck, has continued his duties until the end of the calendar year, and in the name of all the Subcommission, I like to express our warmest thanks to him for all his efforts, his enthusi- asm for our tasks, his patience with the often too slow progress of research, and for the humorous, well organized and skil- ful handling of our affairs, including our annual meetings. At the same time I like to thank all our outgoing Titular Members for their partly long-time service and I express my hope that they will continue their SDS work with the same interest and energy as Corresponding Members. The new ICS rules require a rather constant change of voting members and the change from TM to CM status should not necessarily be taken as an excuse to adopt the lifestyle of a “Devonian pensioner”. I see no reason why constantly active SDS members shouldn´t become TM again, at a later stage. On the other side, the rather strong exchange of voting members should bring in some fresh ideas and some shift towards modern stratigraphical tech- niques. -
Sequence of Post-Moult Exoskeleton Hardening Preserved in a Trilobite Mass Moult Assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco
Editors' choice Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco HARRIET B. DRAGE, THIJS R.A. VANDENBROUCKE, PETER VAN ROY, and ALLISON C. DALEY Drage, H.B., Vandenbroucke, T.R.A., Van Roy, P., and Daley, A.C. 2019. Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco. Acta Palaeontologica Polonica 64 (2): 261–273. Euarthropods have a tough exoskeleton that provides crucial protection from predation and parasitism. However, this is restrictive to growth and must be periodically moulted. The moulting sequence is well-known from extant arthropods, consisting of: (i) the long inter-moult stage, in which no changes occur to the hardened exoskeleton; (ii) the pre-moult stage where the old exoskeleton is detached and the new one secreted; (iii) exuviation, when the old exoskeleton is moulted; and (iv) the post-moult stage during which the new exoskeleton starts as soft, thin, and partially compressed and gradually hardens to the robust exoskeleton of the inter-moult stage. Trilobite fossils typically consist of inter-moult carcasses or moulted exuviae, but specimens preserving the post-moult stage are rare. Here we describe nine specimens assigned to Symphysurus ebbestadi representing the first group of contemporaneous fossils collected that preserve all key stages of the moulting process in one taxon, including the post-moult stage. They were collected from a single lens in the Tremadocian part of the Fezouata Shale Formation, Morocco. Based on cephalic displacement and comparison to other trilobite moults, one specimen appears to represent a moulted exoskeleton. -

Why did the UV-A-induced photoluminescent blue–green glow in trilobite eyes and exoskeletons not cause problems for trilobites? PeerJ 3:e1492 https://doi.org/10.7717/peerj.1492 Why the UV-A-induced photoluminescent blue-green glow in trilobite eyes and exoskeletons did not cause problems for trilobites? Brigitte Schoenemann, Euan N.K. Clarkson, Gábor Hórváth The calcitic lenses in the eyes of Palaeozoic trilobites are unique in the animal kingdom, although the use of calcite would have conveyed great advantages for vision in aquatic systems. Calcite lenses are transparent, and due to their high refractive index they would facilitate the focusing of light. In some respects, however, calcite lenses bear evident disadvantages. Birefringence would cause double images at different depths, but this is not a problem for trilobites since the difference in the paths of the ordinary and extraordinary rays is less than the diameter of the receptor cells. Another point, not discussed hitherto, is that calcite fluoresces when illuminated with UV-A. Here we show experimentally that calcite lenses fluoresce, and we discuss why fluorescence does not diminish the optical quality of these lenses and the image formed by them. In the environments in which the trilobites lived, UV-A would not have been a relevant factor, and thus fluorescence would not have disturbed or confused their visual system. -

Brisbane. ISSN0079-8835. Aconsolidated list of available generic names introduced since the beginning of the binomial nomenclature system for trilobites is presented for the first time. Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work. We also provide a list of names that have apparently been applied to trilobites but which remain nomina nuda within the ICZN definition. Peter A.

Storm-Dominated Shelf and Tidally-Influenced Foreshore Sedimentation, Upper Devonian Sonyea Group, Bainbridge to Sidney Center, New York
413 STORM-DOMINATED SHELF AND TIDALLY-INFLUENCED FORESHORE SEDIMENTATION, UPPER DEVONIAN SONYEA GROUP, BAINBRIDGE TO SIDNEY CENTER, NEW YORK DANIEL BISHUK JR. Groundwater and Environmental Services, Inc. (GES) 300 Gateway Park Drive North Syracuse, New York 13212 ROBERT APPLEBAUM and JAMES R. EBERT Dept. of Earth Sciences State University of New York College at Oneonta Oneonta, New York 13820-4015 INTRODUCTION The Upper Devonian paleoshoreline of the Catskill clastic wedge in New York State has been interpreted for nearly a century as a complex deltaic sequence (Barrel, 1913, 1914; Chadwick, 1933; Cooper, 1930; Sutton, Bowen and McAlester, 1970; and many others). Friedman and Johnson (1966) envisioned this deltaic complex as a series of coalescing deltaic lobes that progressively filled the Catskill epeiric sea and existed as an uninterrupted deltaic plain from New York to West Virginia. In addition, some geologists believe that such epeiric seas were tideless owing to rapid tidal wave attenuation (Shaw, 1964; and Mazzullo and Friedman, 1975). Others presume that storm (wave) processes were dominant with little or no tidal influence (Dennison, 1985). This study offers significant departures from these interpretations, by documenting nondeltaic environments with significant tidal influence along the Catskill paleo-shoreline. The purpose of this study (Fig. 1) is to delineate sedimentary environments spanning the nonmarine to marine transition in the Upper Devonian Sonyea Group and to test and challenge previous deltaic models of the Sonyea Group (Sutton, et al., 1970). Recent publications have introduced evidence for non-deltaic shoreline environments within the Catskill clastic wedge (Walker and Harms, 1971 ; 1975; Bridge and Droser, 1985; VanTassel, 1986; also see Seven, 1985, Table 1, p.
