The vertebrate assemblage of Buenache de la Sierra (Upper Barremian of Serrania de Cuenca, Spain) with insights into its taphonomy and palaeoecology

A holistic approach to the palaeoecology of Las Hoyas Konservat-Lagerstätte (La Huérguina Formation, Lower Cretaceous, Iberian Ranges, Spain)

“…Conversely, some fossil associations preserved in taphonomic environments, which result in worse preservational quality, contain better quality palaeoecological information than some Konservat-Lagerstätten. This is the case for some microfossil assemblages of La Huérguina Limestone Formation located close to Las Hoyas, whose paleoecology is similar to that revealed by the Las Hoyas analysis (Buscalioni et al, 2008). In this sense, it would be worth comparing Las Hoyas to other fossil localities with respect to their palaeogeography and age, in an attempt to determine whether they share taphonomic and palaeobiological commonalities that can contribute to our understanding of the potential megabias during the Lower Cretaceous and to contrast the dynamic hypothesis of long-term ecological stability.…”

“…Results from Buscalioni et al (2008) reveal that Las Hoyas was dominated by obligate aquatic taxa (64%; in this previous study arthropods and macrophytes were excluded, although crustaceans, and some insects groups are also obligate aquatic), 24% of amphibious taxa, but fewer facultative to incidental forms (12%).…”

“…Since it was discovered in 1985 it has yielded several thousand ichnofossils and body fossils, the latter including Bacteria, Fungi, Protista (Foraminifera), Algae, and a wide spectrum of Plant and Animal phyla (Buscalioni et al, 2008;Fregenal-Martínez and Buscalioni, 2009, see below). It is especially well known as probably the best Mesozoic locality for fossil insects (Martínez-Delclós et al, 2004).…”

Larachelus morla, gen. et sp. nov., a new member of the little-known European Early Cretaceous record of stem cryptodiran turtles

“…1996;Escaso et al 2005;Torcida Fernández-Baldor 2006;Pereda-Suberbiola et al 2007;Sánchez-Hernández et al 2007;Buscalioni et al 2008;Gasulla et al 2009Gasulla et al , 2011Mateus et al 2011). Holtz et al (2004) proposed that the Greater Wealden, comprising localities of the Lower Cretaceous of England and continental Europe, as well as comparable faunas of southern and central Europe, western North America, and Africa, share a common composition of dinosaur faunas.…”

Growth mechanisms in dinosaur eggshells: an insight from electron backscatter diffraction

“…Even though research on the vertebrate palaeontology of the Early Cretaceous of Spain has mainly focused on skeletal remains, eggshell fragments are among the most abundant fossils in the microsites of the Iberian Range (Köhring 1990;Buscalioni et al 2008;Amo-Sanjuan et al 2000;Moreno-Azanza 2009a, b), and they are present in high diversity. These are unlikely to represent egg debris from a single nesting area; nevertheless, they are probably a representative sample of the taxa nesting in the ecosystem (Moreno-Azanza et al 2009a).…”
