微波炉爆米花摘要：A graptolite fauna from the Wallace Shale at Cheemans Creek, west of Orange, central west New South Wales, gives a clear Pridoli age for the lower half
of the Wallace Shale in that area. Previous identifications of species from the Wallace Shale are revid in a description of the fauna. The following taxa are described: Dictyonema delicatulum cf. barn
byensis, Pristiograptus shearsbyi, Monograptus transgrediens, M. prognatus, M. bouceki and M. hornyi. Three evolutionary lines are suggested for the M. bouceki species group: a) M. uncinatus praeprognatus M. prognatus M. uniformis; b) M. uncinatus s.l. M. pridoliensis; c) M. uncinatus s.l. M. hornyi M. bouceki.qq密码泄露
