Environment
Lithology: mudstone
Taphonomic context: fluvial deposit,overbank deposit
Habitat comments: "overlain by 60 cm thick clayey mud. The colour of this horizon changes... to dark grey and almost black" (Joniak et al 2020)
"The Fp facies composition lacks alteration marks, and thus was not subaerially exposed and represents a poorly-drained floodplain, possibly a shallow swamp" (Joniak et al 2020)
