Abstract

This study provides a comprehensive taxonomic analysis of ostracod species from the Jingchuan Formation in the Ordos Basin. We identified six species from four genera: Cypridea koskulensis, Mongolocypris sp., Lycopterocypris debilis, Djungarica aff. saidovi, and Alicenula spp. Our newly ostracod biostratigraphic data suggests that the Jingchuan Formation is dated to the Aptian. Moreover, our findings corroborate the hypothesis of non-marine ostracod faunal exchange in East Asia during the Early Cretaceous. This new temporal constraint also enhances our understanding of the age of Cretaceous aeolian desert sediments and red beds within the Ordos Basin.

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
