[2] The Ukureyskaya Formation was mentioned by Sinitsa & Starukhina (1986),[3] and was first discovered by Sofia M. Sinitsa and her team from the Russian Academy of Sciences before being excavated in 2010 by a group of Russian and Belgian palaeontologists;[4] during this time, the holotype of Kulindadromeus zabaikalicus was discovered.

[6] The volcanic ash layers of the Ukureyskaya Formation form a Konservat-Lagerstätte with an exceptional preservation,[1] and it likely represents a nearshore lacustrine or estuarine-deltaic environment similar to the Yixian Formation.

Sinitsa & Starukhina (1986) and Sinitsa (2011) suggested that the Ukureyskaya Formation dated to the Late Jurassic-Early Cretaceous.

[3][4] Godefroit et al. (2014) and Alivanov & Saveliev (2014) have suggested that as a whole, the Ukureyskaya Formation dates to the Bajocian-Tithonian,[5][7] while more recent dating work by Cincotta et al. (2019) suggests that the layers containing the remains of Kulindadromeus are Bathonian in age.
