Abstract
Based on distinct morphologic features of the tests of 16 spp. of the genus Hantkenina and of the geologic ranges, this stratigraphically important fossil is subdivided into the following subgenera: Hantkenina (sub-genotype : H. alabamensis); ARAGONELLA (subgenotype: H. mexicana var. aragonensis); APPLINELLA (subgenotype: H. dumblei), and CRIBROHANTKENINA (subgenotype: H. bermudezi Thalmann nom. nov.). The genus Hantkenina, sensu lato, is regarded as a typical Eocene fossil. Occurrences reported from Lower Oligocene beds are believed to be questionable.This publication has 0 references indexed in Scilit:
