New discoveries of corystosperm seed-bearing structures from the Tevshiin Govi locality, Mongolia, which is of Early Cretaceous (Aptian–Albian) age, show that the individual seed-bearing units of Umkomasia mongolica were borne in a cone, as also documented for the very similar reproductive units of Doylea tetrahedrasperma. New material from the Tevshiin Govi locality also documents two additional species of Umkomasia – U. corniculata sp. nov. and U. trilobata sp. nov. – that most likely grew in… 

Silicified cupulate seed-bearing structures from the Early Cretaceous of eastern Inner Mongolia, China: rethinking the corystosperm concept

The group referred to informally as the corystosperms, described initially based on compression fossils from the Triassic of Gondwana, have long been considered critical extinct plants for

Exceptionally well-preserved Early Cretaceous leaves of Nilssoniopteris from central Mongolia

Abstract Two new Early Cretaceous (Aptian-Albian) species of fossil bennettitalean leaves are described from central Mongolia and assigned to the genus Nilssoniopteris. Nilssoniopteris tomentosa

Reconstructing Krassilovia mongolica supports recognition of a new and unusual group of Mesozoic conifers

Paracytic stomata, and other features of this new group, recall features of extant and fossil Gnetales, raising questions about the phylogenetic homogeneity of the conifer clade similar to those raised by phylogenetic analyses of molecular data.

Geminispermum, an Early Cretaceous (early–middle Albian) cupulate unit from the angiosperm-dominated Puddledock flora of eastern North America

Geminispermum is currently the only unequivocal seed plant cupule recovered from the Early Cretaceous Potomac Group and is distinct from all previously described cupulate reproductive structures.

The Early Cretaceous Mesofossil Flora of Torres Vedras (Ne of Forte Da Forca), Portugal: A Palaeofloristic Analysis of an Early Angiosperm Community

An Early Cretaceous mesofossil flora is described from the lower part of the Almargem Formation from Torres Vedras (NE of Forte da Forca), Portugal and shows a marked underestimation of angiosperm diversity in the palynoflora.

Pseudotorellia Florin from the Upper Jurassic–Lower Cretaceous of the Bureya Basin, Russian Far East

The leaves of the genus Pseudotorellia from the Upper Jurassic–Lower Cretaceous of the Bureya Basin (Russian Far East) have been revised. The similarity of Pseudotorellia angustifolia Doludenko and

Relictual Lepidopteris (Peltaspermales) from the Early Jurassic Cañadón Asfalto Formation, Patagonia, Argentina

L. scassoi and other members of its lineage are interpreted as fast-growing, long-lived shrubby to herbaceous plants that thrived in waterside environments and show a similar overall pattern of origination, diversification, and decline (late Early-Middle Triassic), with relict occurrences during the Early Jurassic.



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

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

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.

Cupressaceae Conifers from the Early Cretaceous of Mongolia

Together with previously described fossils, Pentakonos and Stutzeliastrobus provide additional evidence that both Cunninghamia-like and Taiwania-like plants were important elements in the early diversification of the Cupressaceae s.l.

Seed ferns from the late Paleozoic and Mesozoic: Any angiosperm ancestors lurking there?

It is concluded that, in the case of these seed plants, phylogenetic analysis techniques have surpassed the hard data needed to formulate meaningful phylogenetic hypotheses.

New perspectives on the Mesozoic seed fern order Corystospermales based on attached organs from the Triassic of Antarctica.

Phylogenetic analysis suggests that the corystosperm cupule is an unlikely homologue for the angiosperm carpel or outer integument, and studies that treat Dicroidium leaf morphospecies as proxies for biological species of entire plants should be reconsidered.

A New Voltzian Seed Cone from the Early Cretaceous of Mongolia and Its Implications for the Evolution of Ancient Conifers

Krassilovia mongolica provides evidence of the additional diversity of extinct voltzian conifers and shows that some persisted to inhabit forest-moor swamp environments in eastern Asia during the Early Cretaceous.

Pinaceae-like reproductive morphology in Schizolepidopsis canicularis sp. nov. from the Early Cretaceous (Aptian-Albian) of Mongolia.

Schizolepidopsis canicularis produced winged seeds that formed in a manner that is unique to Pinaceae among extant conifers, and may potentially help reconcile the appearance of the family in the fossil record with results based on phylogenetic analyses of molecular data.

The presumed ginkgophyte Umaltolepis has seed-bearing structures resembling those of Peltaspermales and Umkomasiales

Well-preserved material from the Early Cretaceous of Mongolia of the previously enigmatic Mesozoic seed plant reproductive structure Umaltolepis is described, supporting previous ideas that Ginkgo may be the last survivor of a once highly diverse group of extinct plants, several of which exhibited various degrees of ovule enclosure.
