Abstract
Owing to its crater-like morphology as well as to geophysical (negative gravity) and geological (superimposed setting) features, the Filippovka (Philippe) buried depression near Novosibirsk, Siberia, can be considered as a possible deeply eroded impact crater of Triassic-Early Jurassic age, with an initial diameter of ~20 km.
