Bargain, 2.9" Spiny Ceratarges Trilobite - Zireg, Morocco

 
 
 
 
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 aries 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.

At almost 3" long this specimen is huge for the species and has been prepared with all of the spines free standing. It's bargain priced due to having around 10% shell restoration. The shell on the back of the head has been restored, about 1/3 of the left genal spine has been restored as well as several areas on the tail.

There are currently about 5 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:
