A new cycad stem from the Cretaceous in Argentina and its phylogenetic relationships with other Cycadales

Mostrar todas las versiones(2)

The cycads are an ancient group of seed plants. Fossil stems assigned to the Cycadales are, however, rare and few descriptions of them exist. Here, a new genus of cycad stem, Wintucycas gen. nov., is described on the basis of specimens found in the Allen Formation (Upper Cretaceous) at the Salitral...
