• coordinate stated in text

• outcrop-level geographic resolution

When: Ilek Formation, Barremian to Barremian (129.4 - 113.0 Ma)

• "Ilekskaya Suite"; several bone-bearing layers within the main "Layer 1"

•

•Skutschas et al. 2017: The dating of the Shestakovo 3 locality within the Lower Cretaceous remains controversial: it has been dated as Berriasian (Alifanov et al. 1999), Aptian–Albian (Averianov et al. 2006), and Barremian–Aptian (Kurochkin et al. 2011) based on vertebrates.

•

•Age of Ilek Formation is poorly constrained but is currently believed to be Barremian-Aptian (see Averianov et al. 2018). The fossiliferous layer at Shestakovo 1 locality was dated to Aptian (Bugadeva et al. 2017). The overlying Kiya Formation has been assigned Albian age based on plant remains (Golovneva and Shchepetov 2010).
