    Morphological Evolution and Extinction of Eodiscids and Agnostoid Arthropods by Huarui Li, Tao Dai, Yanlong Chen, Chunling Xue, Luke C. Strotz

    Published 2024-12-01
    “…Subsequent reductions in agnostid morphospace occupation coincide not only with significant abiotic changes and associated extinction events, such as the Botoman–Toyonian Extinctions (BTEs), the Redlichiid–Olenellid Extinction Carbon Isotope Excursion (ROECE), the Drumian Carbon Isotope Excursion (DICE), and the Steptoean Positive Carbon Isotope Excursion event (SPICE), but also with major evolutionary episodes, such as the Great Ordovician Biodiversification Event (GOBE). …”
