1.85" Alien Looking Ceratarges Trilobite

 
 
 
 
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 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.

The preparation on this specimen is good with great surface detail and free-standing spines. There is a head of a second specimen right next to the first. There are a few small patches of shell restoration on the head.

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 here. This one appears to be Ceratarges koumalii
