Lithology and environment
| Primary lithology: | desiccation cracks,wave ripples,bioturbation,gray sandstone |
| Includes fossils? | Y |
| Lithology description: "fine-grained, well-sorted light grey sandstone...heavily dinoturbated surface...irregular patches of wave ripple marks on the surface are evidence that at least some of the track area was under shallow water at some point. Invertebrate traces and syneretic mud cracks are also observed on the surface. Invertebrate traces are represented by Skolithos associated with algal mats, which are indicative of shoreline faces." | |
| Environment: | "floodplain" |
| Geology comments: "low-lying coastal plain" | |
