摘要(Abstract)：

贵州关岭一带的杨柳井组下部产安尼期与拉丁期界线附近的牙形刺Nicoraella kockeli(Tatge),Neogon-dolella constricta cornuta,Neog.constricta postcornuta,Neog.bulgarica,Neog.trammeri及Neog.alpinaalpina等;与匈牙利的Felsoors剖面相似,在该剖面上可以识别出Neogondolella constricta cornuta-Neog.constricta post-cornuta演化关系,据此推断,杨柳井组下部的时代为安尼晚期,杨柳井组上部的时代为拉丁期。牙形刺的发现为确定杨柳井组的时代提供了可靠的化石依据,并为该区安尼—拉丁期地层的划分和对比奠定了基础。
