NHMUK It 29318 is an assemblage of 9 dorsal exoskeletons of cephala of differing sizes, the smallest having a length (sag.) 37% of the largest. In the Devonian of the Anti-Atlas, it is very rare to find such a wide intraspecies size range in trilobite specimens at the same locality. For some yet to be explained reason, differing holaspid development stages are poorly represented. The Upper Ordovician, Silurian and Devonian assemblages in obrution deposits figured by
