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). ^[75]
• 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. ^[76]
• 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). ^[77]
