The First Occurrence in the Fossil Record of an Aquatic Avian Twig-Nest with Phoenicopteriformes Eggs: Evolutionary Implication
(Public Library of Science, 2012-10-17)
Background: We describe the first occurrence in the fossil record of an aquatic avian twig-nest with five eggs in situ (Early Miocene Tudela Formation, Ebro Basin, Spain). Extensive outcrops of this formation reveal ...
Middle Eocene Rhodoliths from Tropical and Mid-Latitude Regions
(MDPI, 2020-03-23)
During the greenhouse conditions prevailing in the early–middle Eocene, larger benthic foraminifers (LBF) spread out on carbonate platforms worldwide while rhodolith beds were scarcely represented. This reduction in ...
Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago
(Pensoft Publ., 2015)
The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the ...
Isotope analyses to explore diet and mobility in a medieval Muslim population at Tauste (NE Spain)
(Public Library Science, 2017-05-04)
The Islamic necropolis discovered in Tauste (Zaragoza, Spain) is the only evidence that a large Muslim community lived in the area between the 8th and 10th centuries. A multi-isotope approach has been used to investigate ...
Benthic foraminifers as a proxy of the range of the tidal wave in the Oyambre Estuary (Cantabria, Spain)
(Elsevier, 2019)
Recent benthic foraminifers from the Oyambre estuary (north of Spain) have been studied in order to learn their biological response to drastic anthropic environmental changes that this estuary has undergone within the last ...
Combining Small-Vertebrate, Marine and Stable-Isotope Data to Reconstruct Past Environments
(Nature, 2015)
Three very different records are combined here to reconstruct the evolution of environments in
the Cantabrian Region during the Upper Pleistocene, covering ~35.000 years. Two of these records
come from Antoliñako Koba ...
Chemostratigraphic and lithostratigraphic signatures of the Anthropocene in estuarine areas from the eastern Cantabrian coast (N. Spain)
(Elsevier, 2015-04)
A range of chemostratigraphic and lithostratigraphic markers of human impacts can be recorded in four estuaries located in the eastern Cantabrian coast (northern Spain). Metal-enriched levels and stable Pb isotopic ratios ...
Relative sea-level changes in the Basque coast (northern Spain, Bay of Biscay) during the Holocene and Anthropocene: The Urdaibai estuary case
(Elsevier, 2015)
In order to reconstruct the environmental evolution process of the Urdaibai estuary in response to sea-level changes in the Basque coast (northern Spain, Bay of Biscay) during the last 8500 years, 10 boreholes were drilled ...
Osteometric analysis of the scapula and humerus of Rangifer tarandus and Cervus elaphus : A contribution to the discrimination of Late Pleistocene cervids
(Inst Paleobiologii Pan, 2014-12)
Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The ...
