    Depositional Environments and Soft Sediment Deformation in the Early Jurassic Ammonitico Rosso Formation of Western Greece by Vasilis Golfinopoulos, David J. W. Piper, Avraam Zelilidis, Georgia Pe-Piper, Penelope Papadopoulou, Nicolina Bourli, George Iliopoulos

    Published 2025-01-01
    “…The presence of well-preserved fossils, such as planktonic and benthic foraminifera, Radiolaria (both Spumellaria and Nassellaria), and ammonites, allowed precise age determinations, suggesting that the first appearance of <i>Globuligerina</i> might predate previous records, occurring first in the Pliensbachian rather than the Toarcian. …”

    Re-evaluation of the Bahariya Formation carcharodontosaurid (Dinosauria: Theropoda) and its implications for allosauroid phylogeny. by Maximilian Kellermann, Elena Cuesta, Oliver W M Rauhut

    Published 2025-01-01
    “…However, due to the destruction of the original material, comparisons of the neotype to the Egyptian fossils have so far only been done cursorily. A detailed reexamination of the available information on the Egyptian carcharodontosaurid, including a previously undescribed photograph of the exhibited specimen, reveals that it differs from the Moroccan neotype in numerous characters, such as the development of the emargination of the antorbital fossa on the nasals, the presence of a horn-like rugosity on the nasal, the lack of a dorsoventral expansion of the lacrimal contact on the frontals, and the relative enlargement of the cerebrum. …”

    The Geological Heritage of Ñandeyvytykuera Geopark Project in Paraguay by Néstor Damian Salinas Franco, Romina Mariel Celabe Gaona, Diego Adán López

    Published 2023-12-01
    “…As for fragility and vulnerability, the Itauguá Fossiliferous Shales GS stands out due to the deterioration and loss of its geodiversity, attributed to a diverse array of unique marine fossils. In conclusion, we recommend adding more locations as a geoconservation strategy, and expanding studies that incorporate quantitative methodologies to provide more precise data and further these and other investigations.…”

    Comparative analysis of the Gran Dolina-TD6 (Spain) and Tighennif (Algeria) hominin mandibles by José-Maria Bermúdez de Castro, Maria Martinón-Torres, Aida Gómez-Robles, Leyre Prado, Susana Sarmiento

    Published 2007-12-01
    “…The dental evidence reveals that North African Middle Pleistocene populations are morphologically closer to African Early Pleistocene populations than to TD6 fossils. We conclude that the Spanish and Algerian hominins belong to different hominin lineages. …”

    Distribution of Trace Elements, Sr-C Isotopes, and Sedimentary Characteristics as Paleoenvironmental Indicator of the Late Permian Linxi Formation in the Linxi Area, Eastern Inner... by Linlin Wang, Yongsheng Zhang, Enyuan Xing, Yuan Peng, Dongdong Yu

    Published 2020-01-01
    “…Based on these investigations, we conclude that the Linxi Formation is mainly composed of clastic sediments, interbedded with limestone lenses, with bioherm limestone at the top of the formation. Inner-layer marine fossils (calcium algae, bryozoans, and sponges) and freshwater and blackish water microfossils (bivalves) are all present, indicative of a typical shallow water sedimentary environment with an open and concussion background. …”

    Quantitative evidence for dimorphism suggests sexual selection in the maxillary caniniform process of Placerias hesternus. by James L Pinto, Charles R Marshall, Sterling J Nesbitt, Daniel Varajão de Latorre

    Published 2024-01-01
    “…Alternative explanations to sexual dimorphism that could account for the dimorphism among these fossils include the presence of juveniles in the sample or time-averaged sampling of a chronospecies, but both have been previously rejected for the Placerias Quarry population. …”

    Tra geologia e architettura. La rappresentazione del paesaggio archeologico di Tiermes by Carlos Rodríguez Fernández, Flavia Zelli, Sagrario Fernández Raga

    Published 2024-12-01
    “…In esso, convergono valori morfologici e topografici che hanno suggestionato lo sguardo dello spettatore a tal punto da essere definito “un gigantesco fossile architettonico”. Il presente scritto ripercorre brevemente la documentazione grafica e fotografica generata per rappresentare il sito oggetto di studio, in una visione in cui geologia, architettura e archeologia si sovrappongono e si confondono, per poi soffermarsi sulla ricerca più recente che – attraverso l’uso dei nuovi sistemi di analisi e rappresentazione dell’architettura – ci offre una nuova interpretazione e rappresentazione del paesaggio di Tiermes. …”
