Trilobite research

• Drage (2024) finds evidence of only minor differences in morphometry between trilobites displaying different modes of moulting. ^[72]
• Trilobite fossil material from the Tiout section in Morocco, representing the first occurrence of trilobites in West Gondwana and some of the oldest trilobite fossils in general, is determined to be approximately 519.62-million-years-old by Sinnesael, Millard & Smith (2024). ^[73]
• 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. ^[74]
• 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). ^[75]
• Hopkins, Gutiérrez-Marco & Di Silvestro (2024) describe fossil material of Leptoplastides salteri from the Fezouata Formation (Morocco), extending known range of this species from Avalonia into Gondwana. ^[76]
• 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). ^[77]
• Bicknell et al. (2024) describe a specimen of Toxochasmops vormsiensis from the Katian Kõrgessaare Formation (Estonia) preserved molted within the body chamber of a nautiloid cephalopod Gorbyoceras textumaraneum, representing the first known record of cryptic molting of pterygometopid trilobites. ^[78]
• A study on the biogeography of Cheirurina during the Ordovician is published by Pérez-Peris, Adrain & Daley (2024). ^[79]

• O'Flynn et al. (2024) describe new fossil material of Bushizheia yangi from the Cambrian Chengjiang Lagerstätte (China), providing new information on its head morphology, and interpret the studied specimens as supporting the interpretation of a six-segmented head as an ancestral state for Deuteropoda. ^[83]
• Redescription and a study on the affinities of Urokodia aequalis is published by Liu et al. (2024), who interpret this arthropod as a basal member of Artiopoda, and interpret its body plan as likely similar to the ancestral body plan for Artiopoda. ^[84]
• Lin et al. (2024) describe new fossil material of Retifacies abnormalis from the Cambrian Helinpu Formation (Yunnan, China) including large specimens with a carapace ornamentation different from what was previously known, and interpret the reported differences as developing during ontogeny, but don't consider them to indicate sexual dimorphs. ^[85]

General research

• 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. ^[86]
