Kasibelinurus amicorum

The holotype (AM F 68969 View Materials ), from the Late Devonian-aged (Famennian, see Holland, 2010) Mandagery Sandstone in Australia was originally described as having LCEs on both sides of the prosoma (see Pickett, 1993). We found evidence for only a single LCE, preserved as an ovate structure on the right prosomal shield ( Fig. 6C–E View Figure 6 ). Ophthalmic ridges are absent. The LCE is located 10 mm from the anterior, 10 mm from the posterior and 18 mm from the lateral boarders and 8 mm from the prosomal midline. The eye has a small amount of relief (2 mm) when considered in profile view ( Fig. 6E View Figure 6 ).
