Rock of the day

Found last weekend during digging activities by Jonathon, another cobble of lias, with striations etched out along laminations and cleavage (?).

This weekend, Brockers recovered this fragmented stalagmite from within the sediment as digging progressed. The cave must have been open a long time for this to form. The image above was taken with LED illumination, the one below using subdued flash.
