Abstract
A new larger benthic porcelaneous foraminifer of soritid affinity is described as Rajkanella hottingerinaformis n. gen., n. sp. from the middle-upper Cenomanian of Kosovo. It occurs in foraminiferal packstones and grainstones, in association with cuneolinids, rhapidionids, chrysalidinids, and other benthic foraminifers. Due to its general morphology and superficial chamber subdivision by exoskeletal elements, Rajkanella n. gen. can be compared with the early Paleogene genus Hottingerina Drobne, 1975, from which it mainly differs in its apertural features, ornamented test, and coiled adult stage. Further differences to coeval Pseudorhapydionina De Castro, 1971, Pseudorhipidionina De Castro, 1971, and to other comparable genera, are discussed. The discovery of Rajkanella hottingerinaformis in the middle-upper Cenomanian is a further witness of the significant radiation and blooming of increasingly complex porcelaneous foraminifers in inner platform, shallow-water depositional settings during that period.
