Lithology and environment
Primary lithology: | green sandstone |
Secondary lithology: | sandstone |
Includes fossils? | Y |
Includes fossils? | Y |
Lithology description: At certain horizons near the top of fining-upwards sequences, bedding planes of buff to green, micaceous , fine-grained sandstones are covered with fragmentary plant remains. Larger axes of Prototaxites/Nematasketum occur in the coarser, massive sandstones. | |
Environment: | fluvial indet. |
Geology comments: sediments are typical of distal alluvial facies of the Old Red Sandstone (Edwards & Fanning, 1985) |
Taphonomy
Modes of preservation: | adpression,permineralized,coalified,original carbon,original sporopollenin,replaced with pyrite |
Size of fossils: | macrofossils,mesofossils,microfossils |
Spatial orientation: | random |
Preservation of anatomical detail: | variable |
Disassociated minor elements: | many |
Fragmentation: | frequent |
Temporal resolution: | snapshot |
Spatial resolution: | allochthonous |
Collection methods and comments
Collection methods: | chemical,mechanical,peel or thin section,field collection |
Reason for describing collection: | taxonomic analysis |
Collection method comments: Lang, 1937 only described Cooksonia; D. Edwards recollected later, but does not indicate how many times. All names except C. hemisphaerica, Parka, and Nematothallus were from the later Edwards' collection(s). | |
Taxonomic list comments:Taken from multiple sources. |
