Zonate lycophyte spores from New Zealand Cretaceous to Paleogene strata

Abstract

RAINE, J.I., June, 2008. Zonate lycophyte spores from New Zealand Cretaceous to Paleogene strata. Alcheringa 32, 99–127. ISSN 0311-5518. The morphology, taxonomy, and stratigraphic occurrence of zonate lycophytic spores recovered from New Zealand Cretaceous to Paleogene strata are reviewed. Five species of Perotrilites include the new species Perotrilites otagoensis described from the Late Cretaceous, and Kraeuselisporites papillatus Harris now transferred to this genus. Kraeuselisporites is represented by a new Late Cretaceous species, Kraeuselisporites alexii. Evansispora, based on the new species Evansispora senonica from Late Cretaceous to Paleocene strata, is proposed for distally reticulate zonate spores of the type met with in modern Lycopodium volubile G. Forst.; Eocene and younger populations are distinguished as Evansispora cenozoica sp. nov. Kraeuselisporites laceratus Norris is transferred to Evansispora. Waiparaspora is established for reticulate zonate spores of different morphology, based on the new Paleocene species Waiparaspora wilsonii.
