It’s Trilobite Tuesday! This crisply-preserved, 1-in- (2.5-cm-) long specimen is one the best examples of the trilobite Acanthopyge ever uncovered in the British Isles. Though trilobites from nearby Wren’s Nest are more renowned, over the last few decades an outcrop in Shropshire, England has begun yielding notable Middle Silurian material. It took over 25 hours of careful preparation (often using only hand tools) to free this trilobite from its limestone matrix.
