Stratigraphy
Lithology and environment
| Primary lithology: | gray conglomeratic sandstone |
| Includes fossils? | Y |
| Lithology description: a series of predominantly red and grey sandstones and siltstones outcrop. The whole series is approximately 1 m thick and in its middle part there is a bed of indurated, dark grey conglomeratic sandstone, which is 30 cm thick, and which outcrops on a surface of approximately 40 m2. All the fossils were collected from this bed, which is also rich in charcoal. | |
| Environment: | marine indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils,mesofossils |
| Preservation of anatomical detail: | good |
| Fragmentation: | occasional |
