Lioharpes aff. venulosus (Hawle & Corda 1847)

Here is a unusual Morocco Harpes Trilobite from the lower Devonian of Atchana in the south western Maider Basin. This Lioharpes is a rare split finish. The Trilobite was nearly completely revealed by just splitting the limestone matrix. This is very unlikely to happen and also unusual for Trilobites from Devonian Limestone. Therefore this Trilobite comes with a positive and negative side. It would be of course still possible to prepare this trilobite further and even transfer the carapace substance from the negative back on the positive side. But in this progress the negative (or external cast) would be simply chiselled away. This Trilobite shows a affinity to the Czech Harpes species Lioharpes venulosus (Hawle & Corda 1847). The eyes are relative wide to the front, the shape and surface sculpture of the Cephalon very similar. On the other side seems the Glabella to be a little lees inflated and the rim furrow of the Glabella seems also less clearly developed. This specimen shows also a faint similarity to Fritchaspis ruderalis Hawle & Corda, 1847. This Harpas was found in the Kohlihapeltis couche what is deeper Pagan age.
