“…The Korsaröd woods have similar ring characteristics to the Purbeck woods, including the possession of intra-annual (false) rings that reflect growth within harsh and variable conditions. Middle-Late Jurassic mid-palaeolatitude woods from Liaoning, China, have generally broader growth rings (average 2.24 mm) but mean sensitivity values (0.33) within the range recorded from the Skåne woods (Tian et al 2015). Middle-latitude woods from the Early Cretaceous of Western Australia have average ring widths of 0.177-9.390 mm and highly variable mean sensitivities (0.148-0.673), although these samples preserved in nearshore marine deposits possibly derive from a broad range of hinterland forest biomes (McLoughlin et al 1995;McLoughlin 1996).…”

Central Skåne (Scania) in southern Sweden hosts evidence of extensive Jurassic volcanism in the form of mafic volcanic plugs and associated volcaniclastic deposits that entomb wellpreserved macro-plant and spore-pollen assemblages. Palynological assemblages recovered from the Höör Sandstone are of Hettangian-Pliensbachian age and those from the overlying lahar deposits are dated as Pliensbachian-early Toarcian (?). Palynomorph assemblages from these units reveal significantly different ecosystems, particularly with respect to the gymnospermous components that represented the main canopy plants. Both palynofloras are dominated by osmundacean, marattiacean and cyatheacean fern spore taxa but, whereas the Höör Sandstone hosts abundant Chasmatosporites spp. pollen produced by plants related to cycadophytes, the volcanogenic deposits are dominated by cypress family pollen (Perinopollenites) with an understorey component rich in putative Erdtmanithecales (or possibly Gnetales), and collectively representing vegetation of disturbed habitats. Permineralized conifer wood attributed to Protophyllocladoxylon sp., belonging to plants that probably produced the abundant Perinopollenites grains, is abundant in the volcanigenic strata, and shows sporadic intraseasonal and multi-year episodes of growth disruption. Together with the relatively narrow but marked annual growth rings, and the annual and mean sensitivity values that span the complacent-sensitive domains, these features suggest growth within Mediterranean-type biomes subject to episodic disturbance.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.

In total, around 26 species across 17 genera of conifer wood have been described in this formation, although most of them are only preserved with secondary xylem (Jiang et al, 2019).…”

“…The Middle to Upper Jurassic Tiaojishan Formation is well developed and widely distributed in western Liaoning Province, north‐east China (Jiang, Yao, Niu, Rao & Li, 2010; Xu, Yang, Tao, & Liang, 2003). Diverse and abundant permineralized plant remains are represented by fern rhizomes (Cheng & Li, 2007; Cheng, Wang, & Li, 2007; Tian et al, 2013, 2014,b; Zhang & Zheng, 1991), cycad stems (Zhang, Wang, Saiki, Li, & Zheng, 2006), as well as ginkgo and coniferous woods (e.g., Jiang et al, 2012; Jiang, Ferguson, Li, & Cheng, 2008; Tian et al, 2015; Wang, Saiki, Zhang, & Zheng, 2006), have been reported.

A new structurally preserved fossil umbrella pine from the Jurassic of East Asia

The Sciadopityaceae are today a monotypic and relict family of the Coniferales, restricted to Japan with an endemic species of Sciadopitys verticillata Sieb. et Zucc., known as umbrella pine. Megafossil remains assigned to the Sciadopityaceae have been reported from various parts of the boreal hemisphere. However, structurally preserved fossil wood of the Sciadopityaceae is poorly documented. Here we present an anatomically preserved fossil wood of the Sciadopityaceae from the Jurassic of East Asia. A new fossil wood Zhangoxylon yanliaoense gen. et sp. nov. is proposed for the specimens, which are anatomically characterized by a heterogeneous pith, endarch primary xylem, and special secondary xylem. The anatomical structures of the new genus are similar to those of the living Sciadopitys except for the type of radial pitting. The present specimen has an araucarian radial pitting, while that of the living Sciadopitys is abietinean. Therefore, Zhangoxylon gen. nov. from the Middle to Late Jurassic (Callovian to Kimmeridgian) in western Liaoning may represent the Sciadopitys‐like petrified wood which bears pith and primary xylem. This new fossil, so far, the best‐known fossil wood of the family Sciadopityaceae, sheds light on the early evolutionary history of the family Sciadopityaceae, and contributes to a better understanding of the palaeoenvironment of the Jurassic Yanliao Biota in East Asia.

“…Xylofloras of China received progressively greater attention over the past decades. An increasing number of Mesozoic petrified woods have been reported from series of horizons in all over China (e.g., Jiang et al 2008;Wang et al 2009Wang et al , 2017Jiang et al 2012Jiang et al , 2016Yang et al 2013;Feng et al 2015;Shi et al 2015;Tian et al 2015Zhang et al 2015Zhang et al , 2016Ding et al 2016;Wan et al 2016). For the Cretaceous records of petrified woods in China, the spatial-temporal distribution pattern is notably unbalanced.…”

The Lower Cretaceous Guantou Formation is known as an important horizon for the Cretaceous petrified woods in southern China. Though abundant Cretaceous wood remains have been found in this formation, only one species has been recognized. A new coniferous wood, Brachyoxylon zhejiangense sp. nov. is described from the Lower Cretaceous Guantou Formation in Xinchang of Zhejiang Province, southeastern China. Anatomically, the new species is characterized by obscure annual rings, mixed type of radial pitting, araucarioid cross-field pits and uniseriate xylem rays. The finding of Brachyoxylon zhejiangense sp. nov. represents the first well-defined record of Brachyoxylon in southeastern China, and enriches the diversity of the Early Cretaceous petrified wood in southern China. Additionally, the new finding sheds new light on further understanding the floral composition, especially the forest vegetation type of the southern phytoprovince in the late Early Cretaceous. Diverse compressed leaf fossils of Cheirolepidiaceae have been described from the Guantou Formation in the fossil locality of the present petrified wood. The co-occurrence of Brachyoxylon zhejiangense sp. nov. and those cheirolepidiaceous leaf fossils provide additional evidences to support that Brachyoxylon may be systematically related to the Cheirolepidiaceae.
