Radiolarian zonations for the Upper Cretaceous have been erected for various geographical locations and for a variety of tirneslices within selected intervals Fig. 5. Radiolaria from the Upper Cretaceous of Bornholm. All scale bars are 50 pm apart from C, which is 100 pm. All specimens are from Sample AK10 of the Arnager Limestone except A-D which are from Sample AK8 of the Arnager Limestone. A, Crucella latum: B, Tesserastrurn quadratum: C, D, Crucella sp. cf.
