Septimopeltis and Basseiarges TrilobitesDescription: The location known as Jorf in Morocco has been a hotbed of new trilobite species for the past few years. This one is most like the trilobite known as Septimopeltis clementina. This one may well be a new genus and/or species yet to be described. For another spectacular example with the pygidial spines prepared free of matrix please see my other offerings. The second specimen in this natural double specimen has been assigned a new genus and species Basseiarges mellishae. The rugose leading edge to cephalon and trailing edge of pygidium is most unusual, and seems to have been taken to extremes in the closely related genus Akantharges (see my other listings). Specimens seem to span a broad spectrum of colors from an ivory to almost black, indicative of the unique mineral composition of the environment in which they have been preserved. The flattened round shape and spines along the edge of the pleural and pygidial lobes indicate to me a dweller of the seafloor. The body configuration would have served the same function as snowshoes.
