Evolutionary history, biogeography, and extinction of the Cretaceous cheirolepidiaceous conifer, Frenelopsis

Frenelopsis Schenk (family Cheirolepidiaceae†) was among the most widespread conifer genera and a dominantelement of wetland ecosystems in low to mid-palaeolatitudes in the the Northern Hemisphere. It was also one ofthe more important peat-forming shrubs and trees generating extensive deposits of Cr...
