The Tsagaanbulag Formation of the Ulaan-Shand section in the Shine Jinst area was assigned to Silurian (Wenlock-Pridoli) previously. But the present authors have found some very important conodonts, including Lanea omoalpha, Amydrotaxis johnsoni, "Ozarkodina"planililingua, Pedavis sp., from the Tsagaanbulag and Amansair formations, clearly indicating that these two formations should be assigned to middle Lochkovian which are widely distributed in China and Mongolia. The existence of the marine Wenlockain and early Ludlovian deposits in Mongolia is a noteworthy problem.

蒙古南戈壁新金斯特(Shine Jinst)地区 Ulaan-Shand 剖面的查干安普拉格(Tsagaanbulag)组以前曾划归志留系(文洛克统至普里多利统).但在Tsagaanbulag 组及其上部的阿曼采尔(Amansair)组发现了非常重要的牙形刺,包括 Lanea omoalpha,Amydrotaxis johnsoni,“Ozarkodina” planililingua,Pedavis sp.,清楚地指明这两个组应当归下泥盆统中洛霍考夫阶.中洛霍考夫阶的海相地层在中国和蒙古国广泛分布.志留系文洛克统和洛德罗统下部的海相地层在蒙古是否存在是值得注意的问题.

Conodont Caudicriodus woschimidti woschmidti has been found from a big outcrop (hill) of the Bayan-Kho-shuu Ruins Section which was 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 Sil-urian. But the strata from where we collected samples M-9～M-12 definitely belong to Lower Devonian (lower Lochko-vian) rather than Lower Silurian. The Mandalovoo Formation should be named Mandalovoo Group, and its three mem-bers should be changed into three formations.

在蒙古南戈壁的Bayan KhoshuuRuins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Caudicrioduswoschimidtiwoschmidti,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。
