Preparation Sequence - Norwegian Pliomera Trilobite

Posted: 10/22/14 02:10 PM : By Matt Heaton : Comments

One new arrival is an unusual Pliomera trilobite from the Huk Formation near Oslo Norway.  These Ordovician trilobites are typically known from Russia but the material from Norway has a dark black shell.  It also is found in MUCH harder limestone so the preparation is more intensive and time consuming.  Below is a preparation sequence for the trilobite using airscribes and finally air abrasives to remove some final matrix from in between the segments.  This trilobite can be found for sale here.

This trilobite was found by breaking limestone and looking for thin cross sections in the rock.  This particular specimen was split through the center and also along the edge of the tail.
