WebPlanar and helical Zoophycos, Helminthopsis, Helminthoida, Sclarituba (Neonereites form), and Chondrites are characteristic. In most schemes, the Zoophycos ichnofacies occurs below storm wave base. At Bluefield, it has displaced the Cruziana ichnofacies above storm wave base due to the maintenance of a dysaerobic environment.

The ichnogenus Nereites includes Nereites irregularis (formerly Helminthoida labyrinthica and Helminthoida crassa). They are relatively small Nereites characterized by large numbers of closely packed deeply meandering trails that tend to coil. The trails are usually horizontal and may be regular to irregular in guidance. The central tunnel is usually thicker than the envelope zone. In dense meanders, the envelope zone may touch or overlap, but it displays low-amplitude lobes i… WebDOI: 10.31390/gradschool_dissertations.3892 Corpus ID: 134078046; Using Trace Fossils to Determine the Role of Oceanic Anoxic Event II on the Cretaceous Western Interior Seaway Paleoenvironment
