Supplementary Data - The Paris Biota decapod (Arthropoda) fauna and the diversity of Triassic decapods

We describe here the early Spathian (Early Triassic) Paris Biota decapod fauna from the western USA basin. This fauna contains two taxa of Aegeridae (Dendobranchiata), namely Anisaeger longirostrus n. sp. and Aeger sp. that are the oldest known representatives of their family, thus extending its temporal range by 5 Myr back into the Early Triassic. This fauna also includes two representatives of Glypheida (Pleocyemata) with Litogaster turnbullensis Schram, 1971 and Pemphix krumenackeri n. sp., comforting for the former, and extending for the latter, the temporal range of their respective superfamily back to the Early Triassic. Overall, the Paris Biota decapods are some of the oldest known representatives of Decapoda, filling in an important gap in the evolutionary history of this group, especially during the Triassic that marks the early diversification of this clade. Additionally, we overview and compile all known Triassic decapods, which leads to the revision of four species of Middle...
