    Reef response to sea-level and environmental changes during the last deglaciation: Integrated Ocean Drilling Program Expedition 310, Tahiti Sea Level by Camoin, G, Seard, C, Deschamps, P, Webster, J, Abbey, E, Braga, J, Iryu, Y, Durand, N, Bard, E, Hamelin, B, Yokoyama, Y, Thomas, A, Henderson, G, Dussouillez, P

    Published 2012
    “…The reef response to sea-level and environmental changes during the last deglacial sea-level rise at Tahiti is reconstructed based on a chronological, sedimentological, and paleobiological study of cores drilled through the relict reef features on the modern forereef slopes during the Integrated Ocean Drilling Program Expedition 310, complemented by results on previous cores drilled through the Papeete reef. …”

    Comparative taphonomy, taphofacies, and bonebeds of the Mio-Pliocene Purisima Formation, central California: strong physical control on marine vertebrate preservation in shallow ma... by Robert W Boessenecker, Frank A Perry, James G Schmitt

    Published 2014-01-01
    “…The strong physical control on marine vertebrate preservation and preservational bias within the Purisima Formation has implications for paleoecologic and paleobiologic studies of marine vertebrates. Evidence of preservational bias among marine vertebrates suggests that careful consideration of taphonomic overprint must be undertaken before meaningful paleoecologic interpretations of shallow marine vertebrates is attempted.…”

    Oology and the evolution of thermophysiology in saurischian dinosaurs: homeotherm and endotherm deinonychosaurians? by Gerald Grellet-Tinner

    Published 2006-01-01
    “…Oological and reproductive characters have collectively provided a new source of data useful for phylogenetic analyses and paleobiological inferences. In addition, the observations of reproductive and oological evolutionary trends in saurischian dinosaurs lead to the interpretation that not only, the thermophysiology of these dinosaurs progressively became more avian-like but after re-examination allows to infer that deinonychosaurians represented here by three troodontids and one dromaeosaurid might already have developed an avian-like endothermy, thus predating the rise of avians. …”

    Published 2018-11-01
    “…Here we present a reconstruction of the Indian winter monsoon in the Arabian Sea for the last 6000 years based on paleobiological records in sediments from the continental margin of Pakistan at two levels of ecological complexity: sedimentary ancient DNA reflecting water column environmental states and planktonic foraminifers sensitive to winter conditions. …”

    Multiproxy analysis of paleoenvironmental, paleoclimatic and paleoceanographic changes during the early Danian in the Caravaca section (Spain) by Gilabert, V, Arenillas, I, Arz, JA, Batenburg, SJ, Robinson, SA

    Published 2021
    “…Based on stable isotopes, calcium carbonate content, magnetic susceptibility and planktic foraminifera, we present a paleoenvironmental, paleoclimatic and paleoceanographic reconstruction of the early Danian from the Caravaca section, Spain, one of the most complete and continuous K-PgB sections worldwide. The paleobiological response of planktic foraminifera suggests very volatile environmental conditions during the first 230 kyr of the Danian, as reflected in the rapid succession of opportunistic/generalist blooms and episodic high occurrences of aberrant specimens. …”

    Integrating gross morphology and bone histology to assess skeletal maturity in early dinosauromorphs: new insights from Dromomeron (Archosauria: Dinosauromorpha) by Christopher T. Griffin, Lauren S. Bano, Alan H. Turner, Nathan D. Smith, Randall B. Irmis, Sterling J. Nesbitt

    Published 2019-02-01
    “…Understanding growth patterns is central to properly interpreting paleobiological signals in tetrapods, but assessing skeletal maturity in some extinct clades may be difficult when growth patterns are poorly constrained by a lack of ontogenetic series. …”

    Planning for the Lake Izabal Basin Research Endeavor (LIBRE) continental scientific drilling project in eastern Guatemala by J. Obrist-Farner, A. Eckert, P. M. J. Douglas, L. Perez, A. Correa-Metrio, B. L. Konecky, T. Bauersachs, S. Zimmerman, S. Scheidt, M. Brenner, S. Kutterolf, J. Maurer, O. Flores, C. M. Burberry, A. Noren, A. Myrbo, M. Lachniet, N. Wattrus, D. Gibson

    Published 2023-10-01
    “…The project is not only an outstanding opportunity to improve our scientific understanding of seismotectonic, volcanic, paleoclimatic, paleoecologic, and paleobiologic processes that operate in the tropics of Central America, but it is also an opportunity to improve understanding of multiple geological hazards and communicate that knowledge to help increase the resilience of at-risk Central American communities.…”

    Mudstones and embedded concretions show differences in lithology-related, but not source-related biomarker distributions by Lengger, Sabine K., Melendez, Ines M., Summons, Roger E, Grice, Kliti

    Published 2020
    “…These are especially notable in places where the mudstone has eroded, giving way to nodule fields, which afford valuable paleobiological records. It is, however, a challenge to determine their paleoenvironmental context. …”

    A shift in redox conditions near the Ediacaran/Cambrian transition and its possible influence on early animal evolution, Corumbá Group, Brazil by Fabricio A. Caxito, Erik Sperling, Gabriella Fazio, Rodrigo Rodrigues Adorno, Matheus Denezine, Dermeval Aparecido Do Carmo, Martino Giorgioni, Gabriel J. Uhlein, Alcides N. Sial

    Published 2024-07-01
    “…To track redox changes during this transition, we present new trace element, total organic carbon and both inorganic and organic carbon isotopes, and the first iron speciation data on the Tamengo and Guaicurus formations of the Corumbá Group in western Brazil, which record important paleobiological changes between 555 Ma to < 541 Ma. The stratigraphically older Tamengo Formation is composed mainly of limestone with interbedded marls and mudrocks, and bears fragments of upper Ediacaran biomineralized fossils such as Cloudina lucianoi and Corumbella werneri. …”
