Trilobite
Kettneraspis
Spiny odontopleurid
Kettneraspis is a small Devonian odontopleurid bristling with paired spines along every segment, prepared from the Moroccan Anti-Atlas and, as K. williamsi, from Oklahoma's Haragan Formation at Black Cat Mountain. The Oklahoma specimens are prepared by a few specialists and are among the finest trilobites sold; Moroccan ones need the usual restoration check.
