UNDVA CLIFF, SAAREMAA, ESTONIA–I’ve never had anything good to say about rain during geological fieldwork, but our colleague Bill Ausich from Ohio State University insisted that it makes echinoderm fossils stand out better against the rock matrix. Turns out he’s right.

Two calices of the eucalpytocrinid crinoids at the Undva Cliff locality.  When wet the pure calcite of their skeletons contrasts brilliantly with the surrounding dark rock matrix.
