The palaeontological virtual collection of the University of Valencia’s Natural History Museum: a new tool for palaeontological heritage outreach
The rise of new digitalization technologies is changing the way to access to the fossil collections for palaeontology outreach, providing new tools to preserve our important palaeontological heritage. In this sense, museums and palaeontological institutions,aware of the advantages of applying these new technologies for the accomplishment of their functions, have started to develop their own online repositories to facilitate the access to the most representative fossil of their collections. Following this trend, the aim of this work is to present the creation of the new “Virtual 3D Collection” of the University of Valencia’s Natural History Museum, showing, as an example, the “Ichnofossil Co…
Ichnological evidence of semi-aquatic locomotion in early turtles from eastern Iberia during the Carnian Humid Episode (Late Triassic)
Abstract Some of the earliest European records of fossil turtle footprints (Late Triassic, Middle Carnian, ~ 227–237 Ma) are interpreted from 46 footprints from three outcrops, Domeno, Quesa and Cortes de Pallas, located in the Iberian Range (eastern Spain). The samples were obtained from Upper Triassic rocks in Keuper Facies. They are characterized in the studied area by two well-defined evaporitic sequences, separated by a detrital stratigraphic interval, constituting the Manuel Sandstones Formation in which the studied fossil footprints were recorded. These fluvial deposits are correlatable with the Carnian Humid Episode. The footprints are tridactyl and tetradactyl, mainly digitigrade, …
Caracterización electroquímica del proceso de degradación de materiales piritosos en colecciones geológicas y paleontológicas: propuestas de tratamiento y conservación
Este trabajo analiza los problemas de conservación y tratamiento de ejemplares paleontológicos y geológicos en los museos centrándonos en ejemplares piritizados, destacando los principales factores que afectan la preservación de este tipo de colecciones. Se ha realizado una intervención en ejemplares paleontológicos y geológicos en la cual han sido tratados para su adecuada conservación. Para caracterizar el proceso de degradación se ha realizado un estudio electroquímico sobre diversos ejemplares conservados en pirita y, de este modo, poder identificar estadios de la degradación presente de los ejemplares (producida en el curso del almacenamiento y conservación). La identificación de estos…
