Planolites

Deltaic Environments. Deltas are depositional environments where a fluvial system’s mouth contacts an open or slow moving body of water, which typically is an ocean or sea. Deltas tend to form fan or triangular shaped deposits of sediment. [1] A delta’s morphology or shape is determined by sediment deposition and transport, as well as by ....

Planolites and Gordia (along with Harlaniella and Torrowangea) are interpreted to represent biodiffusive bioturbation. Both Planolites and Gordia are essentially surficial traces, although Droser et al. interpret Planolites as having been shallowly penetrative, in which case Planolites trace-makers could also have been biodiffusors.Recovery – 2011 CSPG CSEG CWLS Convention 2 many of the reservoirs in the Western Canada and Williston basins (Creaney and Allen, 1990; LeFever et al. 1991).

Planolites Nicholson, 1873 DESCRIPTION: Simple, unlined, unbranched cylindrical or subcylindrical infilled burrows, straight to gently curved, horizontal to oblique to bedding planes. Burrows may cross-over. Lithology of fill differs from that of host rock. BEHAVIOR(S): Fodinichnia (deposit feeding), domichnia (dwelling).Nov 1, 2019 · Trace fossils produced by terrestrial insects or annelids – Planolites, Taenidium, and Naktodemasis – support the notion of a continental setting (Savrda et al., 2000). On the other hand, unstructured to crudely structured muddy sandstone and sandy mudstone (F8; Fig. 5 F) suggests slow deposition rates between active zones of sediment delivery.
