Lithology and environment
| Primary lithology: | concretionary,pebbly,yellow sandstone |
| Secondary lithology: | mudstone |
| Includes fossils? | Y |
| Lithology description: "The specimen was found in a 40-mm-thick bed of yellowish, heterogeneous sandstone with rhizoliths, mudstone pebbles, carbonate concretions, coprolites, and vertebrate remains. Levels above and below show similar heterogeneity, especially the overlying levels that present alternations of mudstones, heterolithic sandstones, and clay pebble conglomerates." | |
| Environment: | fluvial-lacustrine indet. |
| Geology comments: "The Helsby Sandstone Formation achieves a maximum thickness of 210 m in Devon and is composed of reddish sandstones and subordinate conglomerates and mudstones; the depositional environment was a network of braided or meandering rivers, bringing water and life to an otherwise arid continental landscape (Ambrose et al., 2014; Coram et al., 2019). The origin of the rivers was located in modern-day France, and the waters flowed northward to the Irish Basin; outcrops of the Helsby Sandstone Formation track this ancient, huge river system, spanning from the south-west to the north of England" | |
