since the year is ending, here are my top discoveries in #paleobotany for 2020 (1/n)
Herrera et al. described new details of the conifer cone Krassilovia mongolica from the Early #Cretaceous of #Mongolia associating it with Podozamites leaves.

Seyfullah, @EmilyAliceR et al. described a fossil cone with affinities with the enigmatic Erdtmanithecales from the Early #Cretaceous of #Brazil that preserves traces of #amber, thus expanding the set of amber-producing plant groups! (3/n) https://bmcevolbiol.biomedcentral.com/articles/10.1186/s12862-020-01651-2
@PaleoNate and Maria Gandolfo described fossil flowers from the #Paleocene of #Argentina, and placed them in the core Cunoniaceae, indicating a role for West #Gondwana in the evolution of this angiosperm family! (4/n) https://academic.oup.com/aob/advance-article-abstract/doi/10.1093/aob/mcaa154/5898989?redirectedFrom=fulltext
@paleogabriella, @RadioGondwana, @IEscapa, and @aanniitttaa described a new species of Araucaria sect. Eutacta from the #Eocene of #Argentina predating molecular age estimates for this group! (5/n) https://bsapubs.onlinelibrary.wiley.com/doi/abs/10.1002/ajb2.1467
@BrianAtkinology described a Late #Cretaceous fossil fruit from #Canada that is the oldest evidence for the mahogany family Meliaceae, an important component of modern #tropical ecosystems! https://bsapubs.onlinelibrary.wiley.com/doi/abs/10.1002/ajb2.1416
Gomez et al. studied the Early #Cretaceous aquatic plant Montsechia from the @las_hoyas
and other localities in #Spain, and reinterpret it as a relative of Ceratophyllum and suggesting an early radiation of this now monotypic group! (7/n) https://onlinelibrary.wiley.com/doi/10.1002/tax.12409

@VeraKorasidis and Wagstaff described pollen floras from the Early #Cretaceous of #Australia, and identify a latitudinal pattern of expansion of #angiosperms in response to climate change! (10/n) https://www.sciencedirect.com/science/article/abs/pii/S0034666719301502?via%3Dihub
@RocioDeanna, @RadioGondwana and Maria Gandolfo described new physaloid fruits from the #Eocene of South America, expanding the early record of #Solanaceae and further confirming an older age for the family! (11/n) https://bsapubs.onlinelibrary.wiley.com/doi/full/10.1002/ajb2.1565?casa_token=UtN1YEJqFE4AAAAA%3AEwWv9rXK5aE_2s6fRu_MM13ueMXTXJBaE7hU1HSKFPSDI-BJaoswi2EEknEXZeFVIeo6NPkbFkx_A0E
Manchester et al. described new fossil Trochodendraceae from the #Paleocene of Wyoming, #USA, using multiple techniques including micro-CT, and place these fossils in the phylogeny of the family!

Also from the Early #Cretaceous of #Portugal, Mendes and Kvacek described a fossil cone of Podocarpaceae preserved as a mesofossil, informing the geographical and morphological range of this family!

also, this year saw the publication of the most abundant #angiosperm from the Aptian (Early #Cretaceous) of #Argentina, which was hiding as a #cycad! (yes, this is shameless self-promotion, but please cut me some slack!) (15/n) https://nph.onlinelibrary.wiley.com/doi/full/10.1111/nph.16657
