On the basis of studies of the graptolite sequence at the Xiaoyangqiao section in the vicinity of Dayangcha Village and at the Qinggouzi and Muxiantougou sections near Hunjiang City, southeastern Jilin, five graptolite zones may be recognized in the ‘Yeli Formation’ in ascending order: 1. Rhabdinopora parabola zone, 2. Anisograptus zone, 3. Psigraptus zone, 4. Callograptus? taizehoensis zone, and 5. Adelograptus‐Clonograptus zone. The correlation of each zone with its equivalents in other areas both in China and abroad and the Cambrian‐Ordovician boundary are discussed.
