中晚侏罗世过渡期是陆生脊椎动物演化的关键时期，但全球从这一时期开始的化石记录相对贫乏。这一时期的石树沟动物群最近产生了重要的恐龙和其他脊椎动物群的化石遗骸，其中一些代表了几个恐龙群和其他脊椎动物群的最早已知成员，一些代表了他们群体中最着名的标本。这些发现对于我们理解几种脊椎动物谱系的起源和进化具有重要意义。放射性测年表明，该动物群的年龄约为159-164 Ma。通过与沙溪庙、燕寮等相似年代的陆生动物群的比较，发现这些动物群在分类学上既有相似之处，也有不同之处，表明准噶尔沉积可能保存了中晚侏罗世劳亚世陆生动物群中最完整的脊椎动物化石记录。
The Middle–Late Jurassic transition period is a critical period for the evolution of terrestrial vertebrates, but the global fossil record from this time is relatively poor. The Shishugou Fauna of this period has recently produced significant fossil remains of dinosaurs and other vertebrate groups, some representing the earliest known members of several dinosaurian groups and other vertebrate groups and some representing the best‐known specimens of their group. These discoveries are significant for our understanding of the origin and evolution of several vertebrate lineages. Radiometric dating indicates that the fauna is aged approximately 159–164 Ma. Comparisons with other similarly‐aged terrestrial faunas such as Shaximiao and Yanliao show both taxonomic similarities and differences between these faunas and indicate that the Junggar deposits might have preserved the most complete vertebrate fossil record for a Middle–Late Jurassic Laurasian terrestrial fauna.
