| 摘 要： | 在蒙古南戈壁的Bayan—Khoshuu Ruins剖面原归入到志留系Mandalovoo组尕屋(Gavuu)段的地层中发现了牙形刺Caudicriodus woschimidti woschmidti，这是泥盆纪最早期牙形刺带化石在蒙古的首次发现。尕屋(Gavuu)段的下部属志留系，但其上部，即采集牙形刺样品M-9～M-12的层位肯定属下泥盆统(下洛霍考夫阶)，而不是下志留统。Mandalovoo组应当改为Mandalovoo群，它的三个段应提升为三个组。 |

| Abstract: | Conodont Caudicriodus woschimidti woschmidti has been found from a big outcrop (hill) of the Bayan-Khoshuu Ruins Section which had been previously assigned to the Silurian Gavuu Member of the Mandalovoo Formation. This is first time to find the lowermost Devonian conodont zonal fossil in Mongolia. The lower part of the Gavuu Member is of Silurian. But the strata from where we collected 4 samples numbered from M-9 to M-12 definitely belong to Lower Devonian(lower Lochkovian)rather than Lower Silurian. The Mandalovoo Formation should be named Mandalovoo Group, its three members should be changed into three formations. |
