In this contribution two coniferous seed cones
organically attached to branches are studied. The fossils were collected at the
Estancia Kachaike locality within the Kachaike Formation of Middle Cretaceous
age from Santa Cruz Province. One type of the seed cones is assigned to Athrotaxis ungeri (Halle) Florin of the
Taxodiaceous and the other to a new member of the Cheirolepidiaceae.
Reproductive and vegetative structures of these conifers are described and
compared with and within other coniferous taxa.
