Lithology and environment
| Primary lithology: | paleosol/pedogenic,concretionary,brown,red calcareous mudstone |
| Secondary lithology: | current ripples,medium,coarse,intraclastic,gray sandstone |
| Includes fossils? | Y |
| Lithology description: "The medium- to coarse-grained gray sandstones...contains rip-up clasts in the base and indicates trough cross-lamination occasionally. Reddish brown fine-grained sandstone, siltstone, and mudstone often include drab-halo root traces and calcareous nodules." | |
| Environment: | lacustrine - small |
| Geology comments: Sandstones might be channel or crevasse splay deposits, mudstones are paleosols. Shallow lacustrine environment near tracksite. | |
