1.95" Spine-On-Spine Ceratarges Trilobite - Top Quality

 
 
 
 
 
 
Now this is one alien looking trilobite, it's almost hard to imagine that it was once alive inhabiting our oceans. It's a Ceratarges ziregensis from the Middle Devonian limestone of Morocco. One can imagine that the large spines may have served as defensive protection against fish that had just begun to develop hardened jaws and likely had trilobites on the dinner menu.

Including the spines this specimen is 1.95" long and the preparation is excellent with tiny spines in place on some of the larger spines. Only one tiny spot of restoration along the repaired crack.

There are currently about half a dozen different species of Certarges described from Morocco each a slight variation on the others. A paper describing some of these species can be found at:
