New fossil Pinaceae from the Early Cretaceous of Mongolia

Abstract: Exceptionally well-preserved pinaceous leaves and seed cones are abundant in unconsolidated Early Cretaceous lignites in central Mongolia. These fossils include two seed cones, both of which have helically arranged bract-scale complexes with two winged seeds on the adaxial surface. The larger of the two seed cones, described as Picea farjonii sp. nov., is cylindrical to ellipsoidal, and was borne terminally on a stout shoot. The bract is small and tridentate. Leaf bases on the shoots are helically arranged, an… Show more

“…Lepidocasus mellonae grew together with several other species of early Pinaceae in the Tevshiin Govi flora, including two species of Schizolepidopsis (Leslie et al, 2013; Matsunaga et al, 2021) as well as Picea farjonii and Pityostrobus stockeyae (Herrera et al, 2016). The disarticulating mature bract–scale complexes of L. mellonae differ from those of P. farjonii and P. stockeyae , which are spreading/flexing cones, in being prominently ribbed and tomentose instead of smooth and glabrous (Figure 6B, C).…”

“…The obscure Jurassic history of Pinaceae contrasts markedly with its diverse and abundant Early Cretaceous fossil record, which documents remarkable morphological diversity, including the seed cone genera Pseudoaraucaria (Alvin, 1957a(Alvin, , 1957b(Alvin, , 1960(Alvin, , 1988Miller and Robison, 1975), Obirastrobus (Ohsawa and Nishida, 1992), and especially Pityostrobus, a likely polyphyletic genus that includes ≥30 species (e.g., Herrera et al, 2016;Smith et al, 2016). Recent phylogenetic hypotheses suggest that several Early Cretaceous Pityostrobus species may belong to stem lineages of extant abietoids and pinoids (Smith et al, 2016;Gernandt et al, 2018).…”

“…iwatsukii in the lignite floras and the exquisite preservation also suggest little long distance transport from the place of growth. The Tevshiin Govi and Tugrug floras were dominated by conifers and other gymnosperms, some of them deciduous, including conifers such as Krassilovia (Herrera et al, 2015; Shi et al, 2017), Schizolepidopsis , Picea , and Pityostrobus in Pinaceae (Leslie et al, 2013; Herrera et al, 2016), Elatides , Stutzeliastrobus , and Pentakonos in Cupressaceae (Shi et al, 2014; Herrera et al, 2017b), the putative ginkgophyte plant Umaltolepis (Herrera et al, 2017a), as well as the corystosperm Umkomasia (Shi et al, 2016). The authors hypothesize that H .…”

“…The shed parts of the Krassilovia plant are a significant component of the Tevshiin Govi lignite, which shows no evidence of higher energy input and appears to have accumulated largely autochthonously. Growing alongside the Krassilovia plant were a variety of other presumed trees, including taxa related to extant Pinaceae (Schizolepidopsis, Picea, Pityostrobus, [65,86]), Cupressaceae (Elatides, Stutzeliastrobus, Pentakonos, [64,87], and the ginkgophyte Umaltolepis [70], as well as plants that may have been shrubs, such as the corystosperm Umkomasia [31,32]. The absence of lycopods and ferns (as macrofossils, mesofossils, or megaspores), other than the epiphytic filmy fern Hymenophyllum [88], suggests there was little or no herbaceous vegetation.…”
