| Includes fossils? | Y |
| Lithology description: "at the base of a 2.1 m thick sandstone layer interbedded within a ca. 23 m thick series of alternating sandstone, mudstone, and claystone rich in plant macrofossils and minor coal seams."; "...large slab of thinly bedded, fine-grained, bioturbated, current ripple-marked sandstone" | |
