| Abstract: | The great majority of plant fossils discussed in this paper were collected from Changliangzi,Dabu and Sangeling Formation in Tianshifu and Saima Basins,Liaoning. They consist of 34 genera and 77 species of plants. We call them Tianshifu Flora. The Tianshifu Flora may be subdivided into three assemblages. 1. Early assemblage. This assemblage represented by fossil plants from the Changliangzi Formation, may be designated as late Early Jurassic in age. It consists of 30 species plants: Equiseturn laterale, Neocalamites carrerei, Todttes denticulata, T. williarnsoni, Coniopieris hymenophylloides, C. simplex, Clathropteris meniscioides, Hausmanma cf. dentata, Cladophlebis asiaiica, C.haiburnensis, C. nebbensis, C. raciborskii, Pterophyllum aequale,P. nathorsti,Anomozamites cf. minor,Nilssonia d,acuminata,N .tenuinervis,Ctenis kaneharia,Gmkgo beijingensis, G. obrutschewi, Baiera gracihs, B. cf. hndleyana, Czekanowskia rigida, Sphenarton atifolia, Phoemcopsis specwsa, "Elandes" chinensis, Elatocladus (Cephalotaxopsisi) angustifohus, E. hndongensis, Slorgaardta mentoukouensis, Lmdleycladus lanceolatus. 2. Middle assemblage. This assemblage represented by fossil plants from the Dabu and Sangeling Formations,may be designated as early-middle Middle Jurassic in age. It consists of 68 species plants. Lycopodites falcaius, Equisetum beani, E. laterale, Neocalamites carrerei, N. hoerensis, Marattiopsis hoerensts, M. muenstert, Todites denticulata, T. ivilliamsoni, Conwpiens hymenophylloides, C. karatiubensis, C. simplex, Dicksonia concinna, D. kendalh, Eboracia lobifoha, Clathropteris meniscioides, C, pekingensis, Hausmanma cf. dentata, Cladophlebis asiatica, C. cf. fukiensis, C. haiburnensis, C. nebbensis, C. raciborskii, C. shansiensis,Plerophyllum aequale,P.angustum, P.issekkulensis,P. nathorsti,P. propinquum,Tyrmia grandifolia, Anomozamites cf. major, Anomozamites spp.,Williamsomella buracovae,W .dabuensis, W. minima, Nilssonia cf. acuminata, N. compta, N. mosserayi, N. orientahs, N. tenuinervis, Ctenis kaneharai, C. lingyuanensis, Kuandiania crassicauhs, Ginkgo beijingensis, G. concinna, G. obrutschewi, G.manchunca,G. sibirica, Baitra asadal, B. furcata, Sphenobaiera gyron, S. huangi, Czekanowskia rigida, Solenites vimineus, Sphenarion latifolia, Phoenicopsis angustifolia,P.aff.speciosa,Leptostrobus laxiflora, Ixostrobus heeri,Pityophyllum longifolium,P.nordenskioldi,Elatides ovalis, "Elatides" chinensis, Slorgaardia mentoukouensis, Ferganiella cf. podozamioides, Linsleycladus lanceolatus. 3. Late assemblage cf Conioptans-Phonicopsis Flora. This assemblage represented by fossil plants from the Houjiatun Formation in Liuhe and Xinbin Basins, may be designated as late Middle Jurassic in age. It consists of 18 species plants: Conioptens burejensis, C. hymenophylloides, C.simplex,Cladophlebis cf. denticulata, pterophyllun sp., Anomozamites cf. minor. Ctems cf. chinensis, Nilssonia sp.,Ginkgo sp., Baiera furcata, Czekanowskia rigida, Phoenicopsis angustifolia, Pityophyllum longifolium, Elatocladus sp., Pagiophyllum sp., Lindleycladus lanceolatus. The Tianshifu Flora and all floras of similar age in North China differ from that of the European-Chinese region in having a very rich representation of the Czekanowskiales, particularly the Phoenicopsis, and a poor record of Bennettitales and Family Matoniaceae.This indicates that the Tianshifu Flora belong to the warmtemprate Siberian palaeofloristic region. |
