The most ancient member of the Sequoioideae – the new genus Krassilovidendron Sokolova, Gordenko et Zavialova (Cupressaceae s.l.) from the Albian–Cenomanian of Western Siberia (Russia)

Late Messinian flora from the post-evaporitic deposits of the Piedmont Basin (Northwest Italy)

“…The origin of both shoots and cones from the same "whole-plant" is supported by the respective morphological correspondence to the same parts of fossil specimens described by Kvaček (1989) R e m a r k s . Pollen grains generally are well preserved but difficult to recognize at the genus or species level in the absence of SEM analyses (Hernandéz-Castillo et al 2005, Sokolova et al 2017, Bouchal and Denk 2020. In this study, only Taxodium/Glyptostrobus-type (Pl.…”

An overview of extant conifer evolution from the perspective of the fossil record

“…Sequoia ‐like reproductive cones (e.g., Quasisequoia Shrinivasan et Friis emend. Kunzmann; Yezosequoia Nishida, Nishida, et Ohsawa; Krassilovidendron Sokolova, Gordenko, et Zavialova; Srinivasan and Friis, ; Nishida et al., ; Sokolova et al., ) appear at the end of the Early Cretaceous, whereas unambiguous members of the taxodioid clade ( Cryptomeria D. Don, Glyptostrobus Endl., and Taxodium Rich) become abundant later in the Late Cretaceous (by ~70 mya) and especially over the Paleogene (Aulenback and LePage, ; Stockey et al., ).…”

Pushing the limits of neutron tomography in palaeontology: Three-dimensional modelling of in situ resin within fossil plants

“…8 sue or matrix allowed the detection of endogenous resin within the fossil plant. Fortunately, in situ resin is not uncommon for coalified plant remains, with numerous recently reported examples within Cupressaceae alone (e.g., Kvaček, 2002;Grimaldi and Nascimbene, 2010;Herrera et al, 2017;Sokolova et al, 2017). One important limitation to consider when applying NT to in situ resin distribution is: it is unlikely that, even when the plant was alive, all resin cavities (whether canals or cysts) would be entirely filled, so the resin distributions must be considered tentative, and volume estimates need to be taken as minima.…”
