Do trilobites have a typical arthropod cuticle?
£1.00
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.
