Abstract A new genus and species, Geminispermum virginiense, is described based on a well-preserved coalified cupulate reproductive unit recovered from the Early Cretaceous (early–middle Albian) Puddledock locality, Virginia, U.S.A. The reproductive unit is bisymmetrical and consists of an axis that bifurcates into two cupule-bearing stalks, each in the axil of a bract. Each cupule stalk bears a single non-valvate cupule recurved towards the center of the reproductive unit. The cupule opens…

Mesozoic cupules and the origin of the angiosperm second integument.

Recurved cupules from a newly discovered silicified peat dating to the Early Cretaceous epoch in Inner Mongolia, China are described and recognition of these angiosperm relatives (angiophytes) provides a partial answer to the question of angiosperms origins.



Early Cretaceous Umkomasia from Mongolia: implications for homology of corystosperm cupules.

A new species of corystosperm seed-bearing organ is described, Umkomasia mongolica sp.

Distinguishing angiophytes from the earliest angiosperms: A Lower Cretaceous (Valanginian-Hauterivian) fruit-like reproductive structure.

They show that nearly total ovule enclosure, a level of organization approaching angiospermy, was achieved by advanced seed ferns during the Mesozoic, and include tetrahedral seeds within cupule- or carpel-like structures.

Early Cretaceous mesofossils from Portugal and eastern North America related to the Bennettitales-Erdtmanithecales-Gnetales group.

Four new genera and six new species of fossil seed are described from five Early Cretaceous mesofossil floras from Portugal and eastern North America, suggesting that this newly recognized complex of extinct plants, together with Bennettitales, Erdtmanithecales, and Gnetales (the BEG group), is phylogenetically closely related.

Anatomy of umkomasia (corystospermales) from the triassic of antarctica.

Both anatomical and morphological features support interpretation of corystosperm reproductive structures as branching systems rather than as compound sporophylls.

Diversity and homologies of corystosperm seed-bearing structures from the Early Cretaceous of Mongolia

The consistent reproductive architecture of the seed-bearing structures in all three corystosperm species, with a bract subtending a variously modified axis bearing ovules, is similar to the situation in Ginkgo and conifers.

Pollen Organs and Seeds with Decussosporites Brenner from Lower Cretaceous Potomac Group Sediments of Eastern USA

Abstract Microsporangiate structures, Brenneria potomacensis gen. et sp. nov., containing pollen grains similar to dispersed Decussosporites are described from the Lower Cretaceous (Barremian or

New Diversity among Chlamydospermous Seeds from the Early Cretaceous of Portugal and North America

The distinctive organization of the seeds seen in Tomcatia, Cattomia, Acanthocatia, and Quadrispermum links them to previously described seeds of Erdtmanithecales and Gnetales, and provides further evidence of a close relationship of some of the dispersed seeds to Bennettitales.

Chlamydospermous Seeds Document the Diversity and Abundance of Extinct Gnetalean Relatives in Early Cretaceous Vegetation

Most of the fossils exhibit combinations of features that are unknown among extant species of Gnetales and clearly represent an extinct complex of plants that were important in Early Cretaceous vegetation, along with other extinct plant groups, including Bennettitales and Erdtmanithecales.
