“…The present fossils most likely originated from the Cretaceous strata, although it is not possible to determine in which formation of the Cretaceous they were preserved. The fossils were accompanied by abundant Tempskya trunks (Yang et al, 2018), fern stems of the Cyatheaceae (Cheng and Liu, 2017;Cheng and Yang, 2018), some gymnosperm woods and a few angiosperm woods (Cheng et al, 2021a). In addition, stem and petiole base fossils of the Osmundaceae were found in the area near Keshan (Cheng et al, 2019(Cheng et al, , 2020(Cheng et al, , 2021b.…”

“…The present fossils undoubtedly come from Cretaceous strata, although it is difficult to determine from which formation precisely they derive. Several trunk fossils, including those of the common Cretaceous taxa Tempskya zhangii Yang et al 2018 and Cycadeoidea Buckland, 1828, have been described from Keshan, approximately 100 km from the fossil locality (Liu et al, 2017; Yang et al, 2018). Other fossils discovered in the same region include tree fern trunks ( Heilongjiangcaulis keshanensis Cheng & Yang, 2018, and Cyathocaulis Ogura, 1927 or Cibotiocaulis Ogura, 1927; Cheng & Liu, 2017; Cheng & Yang, 2018), and conifer wood ( Sequoioxylon zhangii Tian et al, 2018b).…”
