• El Albani et al. (2024) report the discovery of exceptionally preserved trilobite specimens from the Cambrian Tatelt Formation (Morocco) fossilized through rapid ash burial caused by underwater pyroclastic flow, providing new information on the trilobite anatomy.^[114]
• A study on the growth and development of Sahtuia carcajouensis and Mackenzieaspis parallelispinosa from the Cambrian Mount Cap Formation (Canada) is published by Handkamer & Pratt (2024), who report evidence of decrease in the number of episodes of segment release in both taxa, possibly as a result of local environmental conditions.^[115]
• Evidence interpreted as indicative of a direct link between the spread of low-oxygen conditions in shallow-water settings and the turnover of trilobites from the North China Platform during the Steptoean positive carbon isotope excursion is presented by Yang et al. (2024).^[116]
• A study on the affinities of harpetid and trinucleioid trilobites is published by Beech, Bottjer & Smith (2024), who argue that the body plan with a wide, flattened cephalic brim or fringe evolved independently in the two groups, and interpret trinucleids as likely specialized asaphids.^[117]
• Evidence from the study of soft-bodied specimens of Olenoides serratus and Triarthrus eatoni, interpreted as indicating that trilobites had five pairs of cephalic appendages, is presented by Hou & Hopkins (2024).^[118]

• Specimens of Dalmanitina socialis preserved with remains of the alimentary tract are described from the Ordovician Letná Formation (Czech Republic) by Fatka, Budil & Mikuláš (2024).^[121]

• Review of the fossil record of millipedes is published by Álvarez-Rodríguez et al. (2024).^[143]

General research

• Turner, McLoughlin & Mays (2024) review the known record of plant–arthropod interactions on Early and Middle Triassic fossil leaves from Gondwana, reevaluate known record of the studied interactions in the Australian Middle Triassic Benolong Flora, and argue that concerted investigations can greatly increase the number of plant–arthropod interactions in the studied fossil assemblages.^[144]
• Loewen et al. (2024) describe a diverse amber deposit from the Maastrichtian strata from the Big Muddy Badlands (Canada), preserving fossils of representatives of seven arthropod orders and at least 11 insect families, and interpret the studied assemblage as providing evidence of a faunal turnover among insects prior to the Cretaceous–Paleogene extinction event.^[145]
