B. N. BERRY, P. WILDE and M. S. QUINBY-HUNT Marine Sciences Group, Department of Paleontology, University of California, Berkeley, CA 94720 (U.S.A.) (Received April 27, 1989) Abstract Berry, W. B. N., Wilde, P. and Quinby-Hunt, M.S., 1989. Paleozoic (Cambrian through Devonian) anoxitropic biotopes. Palaeogeogr., Palaeoclimatol., Palaeoecol., 74:3 13. The oxygen-poor to denitrified waters of modern oceans provide an analog for open ocean conditions which contained the Early Paleozoic "graptolite" biotope. Certain euphausiids, other zooplankton and fish, as demonstrated in the Eastern Tropical Pacific, are found concentrated in and about denitrified waters. The boundary zone between oxic and denitrified waters show intense organismal growth due to the increased chemical availability of nutrients as reduced nitrogen compounds. Such waters are areally limited in the present cold and well-ventilated modern ocean. The distribution patterns showing attraction to low or oxygen-depleted waters (anoxitropy) in these modern open marine faunas suggest that Early Paleozoic plankton and nekton, preserved in lithofacies formed under low oxygen or anoxic coditions, could have been similarly attracted to the more extensive ancient denitrified and anoxic waters. The major Paleozoic faunal groups, in order of their occupation of the niche, include agnostid and olenid trilobites, graptoloid graptolites, styliolinids, thin-shelled bivalves, small orthocone nautiloids, and early ammonoids. The expansion of low-oxygen to anoxic waters across the shelves during warm climates in the Early Paleozoic may be correlated with major evolutionary radiations in the graptolites and possibly in the early ammonites. -

Komm. 17: 199-213, 2 Figs., 2 Pis., Wien. Abstract: The Devonian history of the Cantabrian Mountains (NW Spain), as registered in the stratigraphic series, is characterized by events of variable importance and geographic significance, which are reflected in the lithology and in the fossil content. They are called geobiologic events. BARNES et al. (1996) mentioned more than 14 Devonian global bioevents. Three of them, the sulcatus, Zlichov-Basal and Daleje-Cance//ata events, have been recognized in the Lower Devonian (Rafieces-La Vid Groups, Lebanza and Abadfa Formations). Another one, the Chotec Jug/eri event, is observed close to the Lower-Middle Devonian boundary (uppermost part of the Moniello, Santa Lucfa and Polentinos Formations; lowermost Eifelian) of the Cantabrian Mountains. In this paper, six phases of development of the Lower Devonian rugose corals from the Can tabrian Mountains, their relation to global sea-level fluctuations as weil as lithologic and palaeon tologic features are analyzed in the neritic (Asturo-Leonian) and pelagic (Palentine) domains.

Givetian Brachiopod Faunas of the Palentian Domain (N Spain)
GIVETIAN BRACHIOPODS PALENTIAN DOMAIN 43 GIVETIAN BRACHIOPOD FAUNAS OF THE PALENTIAN DOMAIN (N SPAIN) Jenaro L. GARCÍA-ALCALDE Departmento de Geología (Paleontología), Universidad de Oviedo, c/ Jesús Arias de Velasco, s/n, 33005 Oviedo, Asturias, Spain. email: [email protected] García-Alcalde, J.L. 2010. Givetian Brachiopod faunas of the Palentian Domain (N Spain). [Braquiópodos del Givetiense del Dominio Palentino (Norte de España).] Revista Española de Paleontología, 25 (1), 43-69, ISSN 0213-6937 ABSTRACT The origin, evolution, structural and stratigraphical features of the Palentian Domain (Cantabrian Mountains, N Spain) are summarily described. The boundaries of the Givetian succession (ca. 40 m thick) in that area are es- tablished from previously known conodont and ammonoid data. The base of the Givetian is situated in the up- per part of the Gustalapiedra Formation, at the base of the La Pedrosa Member. The upper Givetian boundary is situated at the top of the lower calcareous interval of the Cardaño Formation. Middle Devonian brachiopods are scarce in the Palentian Domain. In fact no Givetian form has been cited in the area until now. In this paper nine brachiopod species (three new) of the Givetian interval are described and figured: Skenidium cf. polonicum, Rhyssochonetes aff. douvillei, Prodavidsonia havliceki n. sp., Bifida aff. lepida, Ambothyris cf. infima, “Pyrami- dalia” palentina n. sp., Cingulodermis sotoana n. sp., Parastringocephalus cf. dorsalis, and Ense andrea. The genera Skenidium, Rhyssochonetes, Ambothyris, Cingulodermis, Parastringocephalus, and Ense are cited in Spain for the first time. Parastringocephalus is moreover the first stringocephaline found in Palencia. “Pyramidalia” palentina n. sp. is an impunctate form provided with a nearly complete symphytium, a delthyrial plate and short dental plates; these features separate the genus Pyramidalia both from Cyrtinaella and Thomasaria with which the former genus has sometimes been synonymised. -

Problematic Sclerites Eurytholia from the Lower and Middle Devonian of the Czech Republic
DOI: 10.2478/fbgp-2019-0001 Michal Mergl, Problematic sclerites Eurytholia from the lower and Middle Devonian of the Czech Republic PROBLEMATIC SCLERITES EURYTHOLIA FROM THE LOWER AND MIDDLE DEVONIAN OF THE CZECH REPUBLIC Michal Mergl Center of Biology, Geosciences and Environmental Sciences, Faculty of Education, University of West Bohemia in Plzeň, Klatovská 51, 306 19 Plzeň, Czech Republic; E-mail: [email protected] Abstract: Problematic phosphatic sclerites Eurytholia are reported for the first time from the Middle Devonian. Unequivocal sclerites were observed in limestones of Emsian to late Eifelian age in six localities of the Barrandian area of the Central Bohemia of the Czech Republic. Formerly observed size and shape variations of Eurytholia sclerites prevent formal description of a new species on few specimens of Emsian and Eifelian age. Therefore the new specimens are identified as Eurytholia aff. bohemica. Their presence indicates longer time range of the Eurytholia animal, covering not only the Ordovician, the Silurian and the earliest Devonian as known formerly, but also late Lower Devonian and the Middle Devonian. Similar features in morphology and histology of Eurytholia indicate relationship to a conodont Pseudooneotodus and a support suggestion about the vertebrate origin of Eurytholia sclerites. Key words: Eurytholia, Pseudooneotodus, problematica, vertebrata, Eifelian, Emsian, Devonian, Barrand- ian area, Czech Republic INTRODUCTION Small hat-like phosphatic plates of unknown ori- enlarged the geographical extent and stratigraphi- gin were firstly reported by Sutton et al.

Both of them possess a complete Paleozoic geological succession ranging from Cambrian to Permian. Type sections and type localities have been studied and designated to both areas. Some limestone units of both geoparks have formed an outstanding feature of spectacular beautiful karst morphology. The geological international significant can be classified into 4 categorizes. 1) The Tarutao Group type stratigraphic section at the Tarutao Island, where many Cambrian-Ordovician index fossils and new genus are found. Furthermore, brachiopod and conodont fossils identified Cambrian-Ordovician boundary. Recently, absolute dating of ash layers found between the index fossil layers at the Cambrian- Ordovician boundary has been studied and this may bring to another indication of absolute age of the Global Boundary Stratotype Section and Points (GSSP). -

Supplementary Information 1. Supplementary Methods Phylogenetic and age justifications for fossil calibrations The justifications for each fossil calibration are presented here for the ‘hornworts-sister’ topology (summarised in Table S2). For variations of fossil calibrations for the other hypothetical topologies, see Supplementary Tables S1-S7. Node 104: Viridiplantae; Chlorophyta – Streptophyta: 469 Ma – 1891 Ma. Fossil taxon and specimen: Tetrahedraletes cf. medinensis [palynological sample 7999: Paleopalynology Unit, IANIGLA, CCT CONICET, Mendoza, Argentina], from the Zanjón - Labrado Formations, Dapinigian Stage (Middle Ordovician), at Rio Capillas, Central Andean Basin, northwest Argentina [1]. Phylogenetic justification: Permanently fused tetrahedral tetrads and dyads found in palynomorph assemblages from the Middle Ordovician onwards are considered to be of embryophyte affinity [2-4], based on their similarities with permanent tetrads and dyads found in some extant bryophytes [5-7] and the separating tetrads within most extant cryptogams. Wellman [8] provides further justification for land plant affinities of cryptospores (sensu stricto Steemans [9]) based on: assemblages of permanent tetrads found in deposits that are interpreted as fully terrestrial in origin; similarities in the regular arrangement of spore bodies and size to extant land plant spores; possession of thick, resistant walls that are chemically similar to extant embryophyte spores [10]; some cryptospore taxa possess multilaminate walls similar to extant liverwort spores [11]; in situ cryptospores within Late Silurian to Early Devonian bryophytic-grade plants with some tracheophytic characters [12,13]. The oldest possible record of a permanent tetrahedral tetrad is a spore assigned to Tetrahedraletes cf. medinensis from an assemblage of cryptospores, chitinozoa and acritarchs collected from a locality in the Rio Capillas, part of the Sierra de Zapla of the Sierras Subandinas, Central Andean Basin, north-western Argentina [1]. -
