Dating Tips for Divergence-Time Estimation
TL;DR: Uncertainty in fossil-dating propagates to divergence-time estimates, yielding estimates that are older and less precise than those based on traditional node calibration, suggesting node and tip calibrations are not mutually incompatible and may be integrated to achieve more accurate and precise evolutionary timescales.

The presumed ginkgophyte Umaltolepis has seed-bearing structures resembling those of Peltaspermales and Umkomasiales
Fabiany Herrera,Gongle Shi,Niiden Ichinnorov,Masamichi Takahashi,Eugenia V. Bugdaeva,Patrick S. Herendeen,Peter R. Crane +6 more
TL;DR: 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.

The fine morphology of pollen grains from the pollen chamber of a supposed ginkgoalean seed from the Middle Jurassic of Uzbekistan (Angren locality)
TL;DR: Pollen grains of Cycadopites-type were found in the pollen chamber of a supposed ginkgoalean seed Allicospermum sp.

Pollen grains associated with gymnospermous mesofossils from the Jurassic of Uzbekistan
TL;DR: The morphology and ultrastructure of the pollen grains show that although some of them belong to ginkgoaleans, others belong to conifers and cycadaleans; this is an argument to be more careful while reconstructing whole plants on the basis of such materials.

The Jurassic of the Western Tien Shan: the Central Kyzylkum Region, Uzbekistan
TL;DR: In this paper, the Sarbatyr inlier in the Kyzylkum area, Uzbekistan contains rare outcrops of Jurassic (Bajocian-Bathonian) rocks which form part of the Kuduksarbatyr Formation.

The Study of Fossil Gymnosperms by Means of Cuticular Analysis
TL;DR: In this paper, the potential use of cuticles for the identification of gymnosperm remains, correlation of their dispersed organs, biostratigraphic, paleoecologic, and paleoclimatologic interpretations are briefly discussed.

An overview of fossil Ginkgoales
TL;DR: Ginkgoales may have lived in various climates and diverse habitats, although most flourished in mesic and temperate climates, and the Late Cretaceous and Cenozoic ginkgos were largely confined to riparian environments.
