Gerastos cf. granulosis
This proetid trilobite from the Devonian of southeast Morocco has previously been called 'Proetus'. The native Berbers call this bug 'Eezee' or fly, as it sort of looks like one and is almost as common. Well-prepared specimens are a little harder to come by though. This particular specimen is from the 'Proetus' layers at Mrakib, Mad'er Region.
