Abstract
Infauna trails (trace fossils) have been identified in rocks of the Bazhenov and Georgiev Formations of the Upper Jurassic of the West Siberian Plate. Two types of trace fossils, Zoophycos and Chondrites, are found in deposits of the Bazhenov Formation, and three types of trails, Chondrites, Thalassinoides, and Skolithos, are recognized in the Georgiev Formation. Conditions of formation have been determined for each type of trace fossils.
