Onega stepanovi placed in phylum Proarticulata, as the segments in recently discovered, exceptionally well-preserved fossils display the glide, or "staggered", symmetry characteristic of the majority of proarticulatans. Imprints of "Onega stepanovi" have been found in the Verkhovka and Zimnie Gory Formations of the Ediacaran (Vendian) rocks of the Arkhangelsk Region, Russia. All the fossil specimens are negative imprints on the bases of fine-grained sandstone beds with the "elephant skin" and tubercle texture diagnostic of microbial mats. The same bedding planes contain various other Ediacaran species: "Cyclomedusa", "Ediacaria", palaeopascichnids, "Eoporpita", "Yorgia", "Andiva", "Archaeaspinus", "Vendia", "Dickinsonia", "Anfesta", "Albumares", "Tribrachidium", "Kimberella", "Parvancorina", "Charniodiscus" and others.
Lake Country Limited Lake Country Limited The Lake Country Limited was a short-lived Amtrak route which connected Chicago, Illinois, with Janesville, Wisconsin. The route was part of Amtrak's Network Growth Strategy, which envisioned an expanded role for mail and express business. The "Lake Country Limited" would have exchanged goods with a new Chicago—New York train named the "Skyline Connection", which in the end never began operation. Trains originated at Chicago's Union Station and ran north over the tracks of Metra's Milwaukee District/North Line. Northwest of Fox Lake, Illinois, it ran over tracks owned by the Wisconsin and Southern Railroad to a temporary platform
