2025 in arthropod paleontology
In 2025, several new arthropod fossil taxa, including arachnids, crustaceans, trilobites, and other arthropods (for insects, see 2025 in paleoentomology) were announced or described. Other significant arthropod paleontological discoveries and events also occurred in 2025.

Ostracod research
- Evidence from the study of Silurian ostracod assemblages from the eastern Baltic Basin (Lithuania), indicating that the mid-Homerian biotic turnover event most likely lasted approximately 260,000 years (and thus was shorter than indicated by earlier estimates), is presented by Rinkevičiūtė et al. (2025).[69]
- Wang et al. (2025) revise the ostracod fauna from the Upper Cretaceous Liwaxia and Madongshan formations (China), correlate it with contemporaneous ostracod faunas from China and Mongolia, and assign the genus Liupanshania to the subfamily Cyproidinae in the family Notodromadidae.[70]
- A study on the composition and biogeographical connections of ostracod assemblages from the Paleocene-Eocene sedimentary succession at Wadi Tarfa (Egypt) is published by Samir et al. (2025).[71]

- Probable burrows of arthropods (possibly insect larvae) feeding on plant roots, as well as their fossilized fecal pellets, are described from the Middle-Upper Triassic strata in Somerset (United Kingdom) by Howson, Tucker & Whitaker (2025).[132]
- Le Cadre et al.
