Summary of site: |
This site is important because it yielded 29 species of Devonian plant spores, allowing the age of these rocks to be firmly established. | A temporary excavation into a little under 2m of green, laminated mudstones and thin coarse grained sandstones near the base yielded fairly well preserved spores (of the 8 mudstones present, 5 were sampled). | Sites rich in spore floras are rare and this prolific site should be designated and protected. |
