elusive Olenoides trispinus is certainly one of the most sought
after and desirable of all Utah trilobite species. Only a handful
have ever been collected in this amazing state of preservation.
Master preparator Dave Comfort of Canada is responsible for this
esthetic display. The specimen is a dark chocolate color, and is
well centered on a large tan colored, well-proportioned plate. It
is fully prone and 3D, with an array of spines characteristic of
the species. The free standing axial spines are in place. When collected,
the specimen was “ghosted” upon discovery. This means
that only a light outline was visible below the overlying matrix.
The matrix was skillfully removed by means of air abrasion. Various
hues of overlying strata are silhouetted around the specimen. There
was no reconstruction, or repairs done. This is a true centerpiece
specimen worthy of a world-class trilobite collection.
are found each year, and very rarely of such high quality. Add in
the professional preparation, and this specimen would be hard to
