<paragraph blockId="7.[810,1457,1364,2028]" pageId="7" pageNumber="1056">The cranidia range from 3.0 mm to 16.0 mm in width and from 2.0 mm to 11.0 mm in length. The shape of the glabella varies from slightly trapezoidal to more equal-sided, with a rounded to truncate front. Three to four pairs of glabellar furrows are preserved mainly in larger-sized specimens.In small-sized specimens, the glabella is steeply domed, while it is flatter in largesized specimens.Nevertheless, the glabella is always more domed than the cheeks.Eye ridges, if preserved, initiate near the front of the glabella and connect with the eye lobes in a horizontal line, some line in a backwards angle towards the sides. The occipital ring points backwards roughly triangularly and the length of the spine varies with size. Some moulds of cephala connected to the thorax spare spines to nodes on up to five axial segments. These and an ornamentation are usually preserved on moulds. Several cephala show up to three variably pronounced grooves. One of these reaches from the front of the glabella to the anterior margin.The other two are developed towards the sides, varying in position. The front of the cranidium is highly domed but a lateral view and microscope measurements indicate that this is an optical illusion and it is still rather flattened domed.</paragraph>
