| Romanovka (PIN collection 2361) | Fleck G., Bechly G., et al (2004) | Zaza | Equivalent to Baissa. C. longipoda, E. trisetalis and Lycoptera all occur in the Zaza Formation indicating that this formation could be correlated with the upper Yixian Formation and the lower Jiufotang Formation in western Liaoning, which have a duration of 122.5-120 Ma. So it is possible to assign the Zaza Formation to an Aptian age. Also correlated with Barremian-Aptian based on plants and pollen. | marl | 125 - 113 Ma Early/Lower Cretaceous |
| Romanovka (PIN collection 3002) | Alexeev A. V. (2011) | Zaza | Correlative with Baissa locality. C. longipoda, E. trisetalis and Lycoptera all occur in the Zaza Formation indicating that this formation could be correlated with the upper Yixian Formation and the lower Jiufotang Formation in western Liaoning, which have a duration of 122.5-120 Ma. So it is possible to assign the Zaza Formation to an Aptian age. Also correlated with Barremian-Aptian based on plants and pollen. | "siliciclastic" | 125 - 113 Ma Early/Lower Cretaceous |
