Palpebralia sp.

Feist, Raimund, 2002, Trilobites from the latest Frasnian Kellwasser Crisis in North Africa (Mrirt, central Moroccan Meseta), Acta Palaeontologica Polonica 47 (2), pp. 203-210 : 206

Palpebralia sp.

Material.—From section “1”, lower trilobite association: 2 cranidia ( UM 2− RF 207–208), 9 pygidia ( UM 2− RF 209–217). From section “2”, upper trilobite association: 1 cranidium ( UM 2− RF 218).

Remarks.—The cranidia resemble Palpebralia brecciae in the form of the facial suture and the absence of any remnant of palpebral lobes, which might indicate absence of eyes. In contrast, the glabella is slender and much longer than that of P. brecciae , whereas there is no diagnostic difference in the pygidia. More material, especially cephala, is needed before these specimens can be identified at the species level.
