Premise of the Study Conifers are an important living seed plant lineage with an extensive
fossil record spanning more than 300 million years. The group therefore provides an …

Volcanogenic-sedimentary and coal-bearing deposits, which contain abundant fossils of a
lacustrine fauna and terrestrial flora, are widespread in the territory of Transbaikalia …

Abstract Background The Florin model is the commonly accepted theory of coniferous seed
scale evolution. It describes the derivation of extant seed scale morphology from the …

The Podocarpaceae are a morphologically diverse conifer family that have a cryptic fossil
record reported since the Permian. We reviewed the fossil record of Podocarpaceae, tested …

Corystosperms, a key extinct group of Late Permian to Early Cretaceous plants, are
important for understanding seed plant phylogeny, including the evolution of the angiosperm …

Pyrite-permineralized fruits and seeds from the London Clay Formation (Ypresian; England)
in the NHMUK are stored in silicone oil to retard decay processes. X-ray micro-computed …

Premise of research. The extinct conifer genus Schizolepidopsis is characterized by deeply
bilobed ovuliferous scales bearing two adaxial seeds. Although it is frequently placed in …

Previously unrecognized anatomical features of the cone scales of the enigmatic Early
Cretaceous conifer Krassilovia mongolica include the presence of transversely oriented …

The origins of the five groups of living seed plants, including the single relictual species
Ginkgo biloba, are poorly understood, in large part because of very imperfect knowledge of …

The plant fossil record during the Cretaceous documents a major transition in the dominant
group of terrestrial autotrophs, as plant communities from the earlier Mesozoic were …
