Trimerocephalus

TRIMEROCEPHALUS Trilobites molted periodically as they grew, and the the trilobite molts of Trimerocephalus are often found preserved. A fossil can be recognized as a molt when all parts of the exoskeleton are present but separated. The head shield is relatively short. There are no eyes and no genal spines. The wide pleurae have down-turned tips. Habitat: This was a deep-water, bottom-dwelling trilobite. Remark: This genus is typically found in Devonian shales. © 1992 Cyril Walker, David Ward .
