Taimyr amber is known from a large number of localities in northern Krasnoyarsk Krai, Siberia, Russia. It ranges in age from Albian (Early/Lower Cretaceous, 113 to 100 mya) to Santonian (Late/Upper Cretaceous, 86.3 to 83.6 mya) (Perkovsky & Vasilenko, 2019).

While a wide range of insects are known from Taimyr amber, only a handful of ants have been found. These occur at two localities, Baikura-Neru Gulf (Late/Upper Albian to Late/Upper Albian, 105.3 - 94.3 mya) (map locality 18) and Yantardakh Hill (Kheta Formation, Late/Upper Santonian, 85.8 - 84.9 mya) (map locality 3).

Ants known from Baikura-Neru Gulf

The amber-bearing deposits of Baikura are layered loose sands, similar to those of the Kheta and Dolgan formations (Zherikhin and Eskov, 1999; Rasnitsyn and Quicke, 2002) dated back to the Santonian, but the only geological report (Saks et al., 1959) refers the locality to the Ognevka Formation (Albian). Upper Albian-?lower Cenomanian in Gumovsky et al., 2017 (fossilworks).
