1.8" Alien Looking 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 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 quality of preservation and preparation on this specimen is top notch with no restoration. There is a slight shift to the right cheek, which accounts for the odd look to the right eye stalk.

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:
