• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Dzunbain Formation, Aptian to Aptian (125.0 - 100.5 Ma)

• "Lower Cretaceous (possibly Aptian)" and from the Khukhtekskaya Svita = Dzunbayn = Dzunbain Formation according to Dashzeveg 1975, but "? Aptian or Albian" according to Wible et al. 2001. Shown in column as "Khobur" beds (Shuvalov, 1974).

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; poorly lithified sandstone

• from illustrated section column in Shuvalov 1974: "unconsolidated and weakly cemented sandstones"

Size classes: macrofossils, mesofossils

Collected by SMPE (1970s), MAE (1990s) in 1970s, 1991, 1997, 1999; reposited in the PIN

Collection methods: bulk, sieve,

• original collections consisted of "About seven tons of sediments... have been washed and screened" and the collection "is housed in the Palaeontological Institute of the USSR Academy of Sciences" under the charge of B. A. Trofimov

Taxonomic list

• Dashzeveg reports that four taxa have been "named but not described" by Trofimov in Beliayeva et al. 1974: Gobioconodon borissiaki, Gobiodon infinitus, Prokennalestes kozlovi, and Prozalambdalestes simpsoni

•numerous later papers by Trofimov, Kielan-Jaworowska, Dashzeveg, and others report the remaining fauna
