The new chronostratigraphic classification of the Ordovician System and its relations to major regional series and stages and to δ13C chemostratigraphy
TL;DR: In this paper, a new global classification of the Ordovician System into three series and seven stages has been proposed, based on a variety of biostratigraphic data.

U-Pb depositional age for the upper Barrios Formation (Armorican Quartzite facies) in the Cantabrian zone of Iberia: Implications for stratigraphic correlation and paleogeography
Gabriel Gutiérrez-Alonso,Javier Fernández-Suárez,Juan Carlos Gutiérrez-Marco,Fernando Corfu,J. Brendan Murphy,Mercedes Suárez +5 more
TL;DR: In this paper, the authors used isotope dilution-thermal ionization mass spectrometry to date zircons from a >45 cm-thick K-bentonite bed within the upper Barrios Formation (Ordovician Armorican Quartzite facies), in the Cantabrian zone of the Iberian Variscan belt.
Proximal and Distal Hummocky Cross-Stratified Facies on a Wide Ordovician Shelf in Iberia
TL;DR: The Monte da Sombadeira Formation (25 m to 200 m thick) crops out repeatedly on the flanks of open folds in an area 550 km long and 140 km wide (approximately 75 000 km2) as mentioned in this paper.
Journal ArticleDOI

Juan Carlos Gutiérrez-Marco,Artur A. Sá,Diego C. García-Bellido,Isabel Rábano,Manuel Valério +4 more
TL;DR: The Arouca Geopark in Northern Portugal has yielded a unique Ordovician fossil lagerstatte that reveals new information on the social behavior of trilobites as mentioned in this paper.
Revisión bioestratigráfica de las pizarras del Ordovícico Medio en el noroeste de España (zonas Cantábrica, Asturoccidental-leonesa y Centroibérica septentrional)
Juan Carlos Gutiérrez-Marco,C. Aramburu,M. Arbizu,Enrique Bernárdez,M.P. Hacar Rodríguez,I. Méndez-Bedia,R. Montesinos Lopez,Isabel Rábano,I. Truyols,E. Villas +9 more
TL;DR: In this paper, a revision completa de mas de un centenar de localidades fosiliferas del Ordovicico Medio situadas en el noroeste del Macizo Hesperico, muestra que the deposito de las pizarras and limolitas oscuras (Formacion Luarca y equivalentes), that siguen a las cuarcitas del Arenig, no fue tan uniforme como se consideraba until ahora.
