| Abstract: | A new galeaspid agnathan,Diploholcaspis daleensis gen.et sp.nov.,was collected from the middle part of the Dayaoshan Group of Dale,Xiangzhou County,Guangxi,China.The Dayaoshan Group is more than one thousand meters in thickness,but yields rare fossils.It is unconformable with pre-Devonian deposits whose age is likely to be the Cambrian(Bai et al.,1982). Based on the depositional sequence and the age of the overlying strata,the Dayaoshan Group was referred to the Lochkovian(Early Devonian) in age(Bai et al.,... |
