最近从藏北安多地区中侏罗统发现较丰富的菊石类化石,巴通期的菊石有Oxycerites oppeli Elmi,Homoeoplanulites cf. homoeomorphus (Buckman),H. cf. acuticosta (Roemer), Choffatia cf. vicenti Mangold, Siemiradzkia cf. matisconensis (Lissajous), Procerites sp. , Neuqueniceras cf. yokoyamai Kobayashi and Fukada 和 Indosphinctes sp. .卡洛夫期的菊石有Oxycerites cf.subcotarius(Oppel),Macrocephalites?sp.,Homoeoplanulitec cf.furculus(Neumayr),Indospinctes ( Elatmites ) cf. reveli Mangold 和 Reineckeites sp. . 其中 Indosphinctes, Indospinctes ( Elatmites ) , Neuqueniceras,Siemiradzkia和Procerites等属(或亚属)在西藏北部地区为首次报道.安多地区中-晚巴通期和早卡洛夫期菊石动物群凸现较强的地方性色彩;晚巴通期ORBIS菊石带和早卡洛夫期KOEMCI菊石带是藏北地区菊石动物群扩散的重要时期.
