Macrofloral remains from the Lower Cretaceous of the Leiva region (Colombia)

Abstract

Lower Cretaceous plant fossils are described systematically from marine deposits near Villa de Leiva (Boyaca region, Colombia). Specimens originating from the same localities kept at the Florida Museum of Natural History (Gainesville) were included in the systematic description. The plant fossils belong to the Pteridophyta, the Cycadophyta, the Coniferophyta, and to taxa of uncertain affinity which, following previous authors, are referred to the angiosperms. Two new species of Coniferophyta are described, viz. Cupressinocladus hoedemaekeri sp. nov. and Brachyphyllum winklerprinsii sp. nov. Also, Thuites sutamarchensis Huertas is transferred to the genus Cupressinocladus. Fossil plants, Lower Cretaceous, Leiva Region, Colombia
