Article: Two new species of herbaceous lycopods from the Devonian of Venezuela with comments on their taphonomy
Two new species of herbaceous lycopods, Haskinsia sagittata and Colpodexylon cachiriense, are described from Devonian strata in the Cano Grande-Rio Cachiri region (north central Sierra de Perija) of Venezuela. The recently discovered diverse assemblage of megafossils also contains the first record of progymnosperms in South America as well as possible cladoxylaleans. The lycopods exhibit a number of preservation forms, and these are related to their putative preservational history. The assemblage is of Laurentian aspect, showing greatest similarity to those from New York State. Its biogeographical significance is briefly discussed in relation to the distribution of continents in Devonian times.
