Integrated chitinozoan, conodont, and graptolite biostratigraphy from the upper part of the Cape Cormorant Formation (Middle Ordovician), western Newfoundland

Canadian Journal of Earth Sciences (2001)

Roberto Albani Gabriella Bagnoli Jörg Maletz Svend Stouge

The Cape Cormorant Formation of the Table Head Group exposed on the Port au Port Peninsula, western Newfoundland, is composed of dark-brown to black shales with interbeds of thin calcareous silty and sandy distal turbidites. Distinctive carbonate conglomerates and breccias derived from the foundering shelf are occasionally found in the formation. The sediments accumulated in the foreland basin formed during the early stage of the Taconic orogeny. The faunas from the upper part of the Cape Cormorant Formation include graptolites, conodonts, and chitinozoans. The graptolites are well preserved, but are of low diversity and are referred to the Darriwil Pterograptus elegans Zone. Conodonts recorded from the distal turbidites are rare and fragmented. The faunas include taxa that are known from the St. George and Table Head groups. The conodont fauna is tentatively assigned to the Histiodella kristinae Phylozone and to the younger, unzoned interval. The chitinozoans are well preserved and the yield is high. The fauna is assigned to the Cyathochitina jenkinsi Zone and to an undefined interval. The abundance and diversity of the chitinozoan assemblages display a cyclic pattern, which is related to changes of the oceanic watermass in the foreland basin. The new chitinozoan species Belonechitina nevillensis n. sp., Belonechitina uniformipunctata n. sp., and Cyathochitina cormorani n. sp. are described.

Bioestratigrafía de la Formación Pizarras del Sueve (Ordovícico Medio) en el sector septentrional de la escama de Laviana-Sueve (Zona Cantábrica, Norte de España)

Spanish Journal of Palaeontology (2022)

J. C. Gutiérrez-Marco Roberto Albani Carlos E. Aramburú Miguel Arbizu Claude Babin

Se presenta el estudio lito y bioestratigráfico de la Formación Pizarras del Sueve en su area tipo de la Zona Cantábrica oriental, a partir de! análisis de nueve perfiles estratigráficos fosilíferos, enclavaclos en sus afloramientos más septentrionales. Estos han posibilitado definir formalrnente la unidacl, constituida esencialrnente por pizarras negras (Miernbros Cerracín y Cofiño), en cuya base pueclen aparecer horizontes de hierro oolítico, separados por un trarno medio de areniscas y pizarras (Miembro Bayo). que alcanzan en conjunto 50-100 m de potencia. El contenido paleontológico es muy notable, identificándose medio centenar de especies de invertebrados marinas (graptolitos, trilobites, ostrácoclos, braquiópodos. rnoluscos, equinodermos) e icnofósiles, a los que se suman de modo preliminar otras setenta especies de microfósiles de pared organica (quitinozoos y acritarcos). Estes últirnos, junto con los graptolitos, aportan informaciones bioestratigraficas muy precisas para la datación y correlación de la formación, cuyo depósito se inicia en el Oretaniense superior tardío (= Abereiddiense superior segun la nueva escala británica), e implica una laguna estratigrafica basal respecto a las cuarcitas de! Arenig.

Lower Ordovician conodonts from Washington Land, western North Greenland

Bulletin of the Geological Society of Denmark (1985)

Svend Stouge Gabriella Bagnoli Stouge Roberto Albani

Early Canadian (Lower Ordovician) conodonts have been recorded from loose slabs which were collected by J. C. Troelsen in 1941 at Kap Clay, Washington Land, western North Greenland. The samples probably derived from the Cape Clay Formation which is exposed in the steep coastal cliff. The macrofauna of the samples includes Symphysurina sp. of Early Ordovician age. The conodont fauna comprises "Paltodus" bassleri Furnish, Utahconus oneotensis (Furnish}, "Oistodus" triangularis Furnish, and species of Cordylodus Pander and "Acontiodus" Pander. The fauna correlates with Fauna C of the North American Midcontinental Faunal succession and with the Cordylodus angulatus Zone of the Baltic-Scania succession. Locally, it correlates with the conodont fauna recorded from the Cape Clay formation of Southern Devon Island, Canadian Arctic Archipelago. The conodont fauna is described applying multielement taxonomy. In all 314 specimens, representing 20 multielement species, were recorded. Some species are new, but they are referred to only in open nomenclature because of the unsettled stratigraphical status of the loose blocks.

Acritarch findings in Early Paleozoic, Low-grade metasediments of Sardinia (Italy): A review.

Spanish Journal of Palaeontology (2022)

Anna Di Milia Marco Tongiorgi Roberto Albani

Acritarchs were found in the weakly metamorphosed deposits of the Hercynian belt of Sardinia (ltaly). Silurian assemblages has been described from the Outer Zone of the Sardinian chain since 1979. From the same zone, recently, Early Tremadocian acritarchs associated with graptolites have also been found. In the Nappe Zone of Central Sardinia the palynomorphs were found in Late Cambrian to Arenigian, terrigenous formations. The preservation of acritarchs in metamorphosed and strongly deformed rocks such as the Sardinian Paleozoic metasediments is discussed. The most important geological implications of the palynological datings are also briefly examined.

First Furongian (late Cambrian) trilobites from the Cantabrian Zone (north-western Spain)

Bulletin of Geosciences (2014)

Guillermo F. Aceñolaza Roberto Albani Enrique Bernárdez Diego C. García‐Bellido J. C. Gutiérrez-Marco

The first Furongian trilobites are described herein from the Cambrian of the Cantabrian Zone, NW Spain.They were collected during the construction of the "Túnel Ordovícico del Fabar" from the shales of "El Fabar Beds" in the La Matosa member of the Barrios Formation.The assemblage includes the aphelaspidine genus Maladioidella, with a specimen identified as M. cf.colcheni, a species previously known from Sierra de la Demanda (Spain), and possibly Sardinia and Oman.Fragments of an indeterminate olenid trilobite and phyllocarid crustaceans have also been recorded.Based on the acritarch assemblage, these beds are considered as late Jiangshanian or earliest Stage 10 of the Cambrian System.The ichnofossil Cruziana semiplicata has also been collected in the tunnel from the upper part of the Ligüeria Member (Tremadocian) of the Barrios Formation, clearly postdating the occurrence of Maladioidella colcheni, its supposed tracemarker according to some authors.The separate record of both taxa (a Furongian trilobite and a Cambro-Ordovician trace fossil) does not support this statement, so their relationship would be refuted in this case.

Late Cambrian acritarch Lusatia: Taxonomy, palaeogeography, and biostratigraphic implications.

Acta Palaeontologica Polonica (2007)

Roberto Albani Gabriella Bagnoli C. Ribecai Elena Raevskaya

Intraspecific variability of the herein emended diacrodian acritarch Lusatia dendroidea is described based on late Cambrian (Furongian) well preserved material from Spain, the High Arctic of Russia, and the East-European Platform. L. dendroidea, displays bipolar asymmetric morphology and, as originally defined, consists of three long major processes originating from the 'corners' of its vesicle. Specimens with one, two and four major processes are considered to represent morphological variations of the most common three process form. Based on its narrow stratigraphic range, widespread palaeogeographic distribution, and distinctive morphology, L. dendroidea is an excellent guide fossil for the Furongian.
