Where: Chita, Russian Federation (52.0° N, 113.2° E: paleocoordinates 55.2° N, 111.5° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Doronino Formation (Chernovskaya Group), Barremian (129.4 - 125.0 Ma)
• Fish fauna is very similar to Aptian Turga and Semen localities, but Chernovskie Kopi is considered to be slightly older by paleoentomologists, so a Barremian age is assigned. Latest Jurassic or Jurassic/Cretaceous boundary ages in the literature are most likely incorrect.
