The Phycosiphon record in the Ladrilleros-Juanchaco section (Miocene, Colombian Pacific): palaeoecological implications
2018
Miocene rocks of the Ladrilleros-Juanchaco section, located on the NW margin of South America, contain a high diverse and abundant trace fossil assemblage. The relative abundance of Phycosiphon, together with its morphological variations, provides new insights into the environmental conditions. Detailed outcrop stratigraphic, ichnological, and geochemical analyses carried out in the section focused on the trace fossil assemblages (distribution, relative abundance), ichnofabric index, and, especially, in the general ichnological features of Phycosiphon . In addition, the detailed photographic documentation and the use of the digital image treatment technique facilitate the precise study of …
Morphologic variation in the P1 element of Mississippian species of the conodont genus Pseudognathodus
2018
A revision of the Austin Conodont Collection at the Natural History Museum, London, has revealed a diverse assemblage of P1 elements of Pseudognathodus . Pseudognathodus homopunctatus, Ps. lineatus, Ps. mermaidus and Ps. symmutatus are di?erentiated and a new species, Ps. posadachaconae , is de?ned from material from North Wales. The systematic of these species is updated. A revised diagnosis is provided for the genus Pseudognathodus , as well as for the species Ps. lineatus and Ps. symmutatus . The types of Ps. symmutatus cannot be differentiated from immature specimens of Ps. homopunctatus . The evolutionary relationships of Pseudognathodus species are discussed. Stratigraphic distributio…
Digitisation as a tool to promote transparency between collections: the case of the Baltic amber from the Königsberg collection at the Museum of Comp…
2019
A total of 383 Baltic amber samples, including 43 type specimens, held at the Museum of Comparative Zoology (MCZ), Harvard University, for near a century were found to belong to the classic amber collection from the Albertus-Universität of Königsberg. This discovery was greatly facilitated by the public availability online of digital images produced during a four-year project that digitised the over 30,000 samples from the MCZ’s fossil insect collection. The amber samples were hand carried and reincorporated to the portion of the original Königsberg collection that was saved from World War II, held at the Geowissenschaftliches Museum from the Geowissenschaftliches Zentrum of the Georg-Augus…
La política económica de Carlos III : ¿Fiscalismo, cosmética o estímulo al crecimiento?
1994
El objeto principal del trabajo consiste en analizar y valorar la acción económica del Estado en España durante el período 1760-1790. Tras sintetizar las principales interpretaciones críticas se estudian tres cuestiones fundamentales para la apreciación de toda política económica: 1. La exposición ordenada de los medios aplicados y la determinación de los fines perseguidos; 2. El proceso político de toma de decisiones y de ejecución, y 3. Las posibles consecuencias de todo ello para el crecimiento económico. La vañoración positiva obtenida, aunque no exenta de penumbras e interrogantes, permite cuestionar algunos fundamentos de las visiones críticas actuales. The object of this paper is to …
