First Record of Upper Cretaceous (campanian?) Larger Benthic Foraminifera From the Yigeziya Formation of the Southwestern Tarim Basin, China

Year: 2024

Type: article

Abstract: Larger benthic foraminifera are described for the first time from the Upper Cretaceous Yigeziya Formation of the southwestern Tarim Basin, China. They occur in middle-outer ramp carbonates with debris of rudists, coralline algae, echinoids, pithonellids, and rare dasycladalean green algae. The material allows an open taxonomic approach for a few taxa. The assemblage includes Charentia cf. cuvillieri Neumann, Cuneolina cf. parva Henson, Nezzazatinella cf. picardi (Henson), orbitolinid gen. et sp. indet., cyclamminid indet., Tetrataxiella? floriforma Schlagintweit & Sanders, Suturina? sp. and the new species Dictyopselloides? tarimensis n. sp. Lacking any resilient stratigraphic data in our material, a Campanian age is tentatively assumed. The benthic association is typical for Neotethys assemblages but also shows conspicuous overlap with the Campanian Tielongtan Formation of western Tibet.
