TOWE, K. M. 1978. Do trilobites have a typical arthropod cuticle?. Palaeontology21, 2, 459–461.

Kenneth M. Towe Problems with specimen preparation and diagenesis make it uncertain whether all trilobites had a laminated cuticle. However, in those trilobites that do show laminations, the cuticles are not only heavily calcified but also lack any evidence of microfibrils or parabolic structures. A heavily calcined cuticle lacking parabolic structures is contrary to that of the typical, generalized arthropod cuticle. The Palaeontological Association (Free Access)
