Rare Middle and Upper Devonian dalmanelloid (Orthida) of the Cantabrian Mountains, N Spain
2018
Rare Cantabrian Dalmanellidae ( Costisorthis lisae nov. sp.), Dicoelosiidae ( Teichertina cf. peregrina , T. cf. ?tzroyensis ), and Mystrophoridae ( Mystrophora sp., Biernatium suco i nov. sp., and Biernatium sp. 2) are described and ?gured for the ? rst time in Spain. Most of them are scarce forms that occur only in certain localities. All the species but one came from the lower part of the Portilla (province of Leon) and Candas (province of Asturias) formations, Faunal Interval 21, Polygnathus rhenanus/P. varcus conodont zone, middle Givetian. The exception is Biernatium sp. 2 that occurs in Asturias in FI 25, Pineres Fm., Palmatolepis transitans zone, lower Frasnian. Costisorthis ranges …
La Neolitización en Cantabria
2019
El territorio actual de la región de Cantabria se corresponde fundamentalmente con el sector central de la Cornisa Cantábrica, además de los valles de Campóo y Valderredible y como la práctica totalidad de trabajos de síntesis realizados tanto en el País Vasco, como en Asturias se circuscriben a sus límites regionales se ha convertido en un importante vacío de información para el estudio del proceso de neolitización en la Cornisa Cantábrica, la poca atención que se ha dispensado a los datos arqueológicos regional origina que las teorías generales sobre el proceso, o los procesos de neolitización en la Cornisa Cantábrica tengan serias lagunas. Con este breve artículo pretendemos contribuir a…
New lithostratigraphy for the Cantabrian Mountains: A common tectono-stratigraphic evolution for the onset of the Alpine cycle in the W Pyrenean real…
2019
The Pyrenean-Cantabrian Orogen arose through the collision of the Iberian and Eurasian plates, mostly in Cenozoic times. This orogen comprises two main mountain ranges, the Pyrenees to the east, and the Cantabrian Mountains to the west. To date, the early Alpine tectono-sedimentary phases preserved in the Cantabrian Mountains, of Permian and Triassic age, have been considered independently from the same phases in neighbouring basins of SW Europe, and even from the eastern part of the same orogeny (the Pyrenean orogeny). In consequence, the beginning of the Alpine cycle in the Cantabrian Mountains has been interpreted within a specific geodynamic context, far from the general evolutionary ph…
SIGNIFICANCE FOR INTERNATIONAL CORRELATION OF THE PERAPERTÚ FORMATION IN NORTHERN PALENCIA, CANTABRIAN MOUNTAINS. TECTONIC/STRATIGRAPHIC CONTEXT AND …
2021
Small ammonoid assemblages are recorded from the Perapertú Formation in northern Palencia. This is a mudstone unit with local platform limestones characterised by carbonate debris flows on the limestone margins. This unit, of Late Bashkirian to Early Moscovian age, participates in a series of southwards verging thrust slicesNorth of a major fault zone which originated as the head (leading edge) of a large thrust sheet with an internal deformation consisting of thrust slices and at least one nappe structure. Opposed vergencies at the head of this major thrust sheet (Carrionas Thrust Front) and the Ruesga Fault which locally modifies its trace, mark the position where the northern branch of t…
Brown bear behaviour in human-modified landscapes: The case of the endangered Cantabrian population, NW Spain
2018
Large carnivores are recolonizing parts of their historical range in Europe, a heavily modified human landscape. This calls for an improvement of our knowledge on how large carnivores manage to coexist with humans, and on the effects that human activity has on large carnivore behaviour, especially in areas where carnivore populations are still endangered. Brown bears Ursus arctos have been shown to be sensitive to the presence of people and their activities. Thus, bear conservation and management should take into account potential behavioural alterations related to living in human-modified landscapes. We studied the behaviour of brown bears in the Cantabrian Mountains, NW Spain, where an en…
