| Includes fossils? | Y |
| Lithology description: "in an area with interbedded sandstone, mudstone, conglomerate, and bitumen-rich silty shale, with petrified logs in a few places." "The matrix remaining on some of the fossil bones is a dark grey sandy siltstone with carbonate cement and carbonaceous fragments...The fine-grained, poorly sorted matrix includes very few large grains with diameters of 2 to 5 mm...The sand fraction consists of quartz, feldspar, mica, and volcanic rock fragments...there are biotite-rich patches within the sample. Minor chlorite is also present...A large lithic clast was also observed." | |
