“…Small pelecypoda shells of micro-mollusks and macro-mollusks at juvenile/very juvenile stages were well preserved, although large shells were broken. These shells showed net breaking lines and sharp edges, which can be interpreted as the result of crab predation (Belgacem et al, 2013; Hadlock, 1980; Lin, 1990; Torres et al, 2020a; Walne and Dean, 1972). Gastropod shells were usually the most well preserved mollusks, in some cases, traces of bio-erosion, and breaking also occurred.…”

“…was substituted by the brackish water association (characterized by the presence of C. glaucum and C. torosa), with less diversity of macro-mollusk and ostracoda, and foraminifera almost totally disappeared. The most abundant micro mollusk was P. conicus, an ever-present inhabitant of marine and marsh environments in the area (Torres et al, 2019(Torres et al, , 2020a.…”

Sedimentological, paleobiological, mineralogical, and geochemical analyses of a sediment core retrieved on the seafront of Cartagena Bay were performed after high-resolution sampling. A wide series of dates obtained through radiocarbon and amino acid racemization proved that the Holocene record on the analyzed core began at ca. 7300 yr cal BP. Reinterpretation of the marine seismic profiles indicated that the beginning of this transgression was channeled along erosive paleochannels excavated on a coastal plain of, at least, MIS5c age. The Holocene paleoenvironmental evolution consisted of a first period marked by marine conditions with strong inputs from a fan delta linked to the reorganized fluvial network that occurred after the sudden rise of the base level, which caused a growing sedimentary prism. Later, the full marine environment was reflected in the development of a Posidonia- Cymodocea meadow hosting a rich biodiversity of marine species (mollusks, foraminifera, ostracoda). Around 3800 yr cal BP, the area underwent a profound change and a silting process started to alter the conditions, turning the area into a paucispecific brackish marsh environment in which mud deposition was dominant. Since Carthaginian times, arrangement works locally affected the record, allowing the arrival of some marine species due to port work (dredging) undertaken to gain depth and showing anthropic influence.

“…In addition, euhaline marsh conditions were interpreted by the presence of a rich biodiversity of ostracodes (C. torosa, L. elliptica, L. rhomboidea, Aurila sp.) and mollusc species (Richards, 1985;Torres et al, 2020) (Fig. 2).…”

Se presentan algunos resultados publicados de campañas de datación por racemización de aminoácidos (AAR) del Laboratorio de Estratigrafía Biomolecular (LEB) de la Escuela de Minas y Energía de la Universidad Politécnica de Madrid, en localidades de la Península Ibérica, que se han seleccionado para mostrar la aplicabilidad del método a muestras de origen biológico muy diverso, foraminíferos, moluscos, crustáceos y mamíferos de diferentes medios geológicos: largos registros de cuenca, terrazas marinas y fluviales, depósitos eólicos y yacimientos en cuevas. Obviamente, no se citan dataciones singulares en muchas localidades. Cerca de veinte mil análisis validan el uso de este método. El método cubre un amplio rango temporal: desde subactual hasta 1.3 Ma; junto con la pequeña cantidad de muestra precisa para los análisis, permite replicar los mismos incluso sobre muestras valiosas de museos u otras instituciones. Asimismo, se puede emplear en determinaciones forenses. Cabe destacar que la pequeña cantidad de muestra necesaria para la realización de un análisis permite emplear un número representativo de muestras de cada nivel objeto de estudio, obteniendo información suficiente para que, mediante un análisis estadístico elemental, se puedan desechar valores anómalos.
