Uncommon Lichid Trilobite Leonaspis chacaltayensis from Bolivia

Here is a trilobite almost never available from the Icla Lutita Formation near La Paz, Bolivia. Variously called Leonaspis chacaltayensis, Leonaspis sp. or Odontopleura sp., this member of trilobite Order Lichida bears striking resemblance to Kettneraspis williamsi from Oklahoma and the various manifestations of Leonaspis from Morocco. There is also debate whether the trilobite is Upper Silurian or Devonian.
