Abstract
Exceptionally rich and well-preserved silicified exuviae comprising numerou s immature growth stages allow the tracing of detailed morphological and mo rphogenetical features of the reduced-eyed phacopid species Cryphops? ensae (Richter and Richter, 1926) from the latest Famennian of Thuringia (Centra l Germany). Ontogenetic features of this species are more similar to those of Phacops than to Trimerocephalus.
