THE VERTEBRATE FAUNA OF THE PRIMAEVA BEDS OF THE FRæNKELRYGGEN FORMATION OF VESTSPITSBERGEN AND ITS BIOSTRATI-GRAPHIC SIGNIFICANCE

New occurrences of Traquairaspis sp., Oniscolepis? sp., Turinia sp., Cephalaspis (Zenaspis) cf. excellens Wängsjö, Nostolepis sp. and Ischna-canthidae gen. et sp. indet. are recorded from the primaeva Beds. Taken as a whole, the vertebrate fauna of these beds shows a general resemblance to those of the upper part of the symondsi zone and the lowermost part of the leathensis zone in the Welsh Borderland. For this and other reasons it is suggested that the Frænkelryggen Formation should be correlated approximately with the symondsi and leathensis zones of the British ‘Psammosteus’ Limestones Group and that the equivalent of the boundary between these zones should be placed either in, or just above, the primaeva Beds.

东北二龙湾玛珥湖晚更新世晚期植被与环境变化的孢粉记录

东北二龙湾玛珥湖孢粉记录显示,34 ka B.P.以来,该区植被和气候经历了以下变化:34-29.3 ka B.P.,发育山地寒温性针叶林,气候冷湿.29.3-12.6 ka B.P.,该区以寒温性针叶林、桦树林为主,气候转向冷干发展,尤其在20.6-18.7 ka B.P.(LGM)时,表现最为突出.12.6-8.9 ka B.P.,该区植被为针阔叶混交林,气候由冷干向温湿逐渐过渡,8.9-4.6 ka B.P.,为落叶阔叶林,气候温暖湿润.4.6 ka B.P.至今,发育针阔叶混交林,气候向温凉转干方向发展.研究表明,MIS3a阶段,以二龙湾为代表的中国东北东部气候以冷湿为主要特征,而末次冰期对该区的影响直到12.6 ka B.P.以后才结束.
