1.45" Spiny Ceratarges Trilobite - Top Quality Specimen

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.

This is a top quality, 1.45" long specimen of Ceratarges koumalii with excellent preparation including free-standing spines. Total restoration is only about 1-2%.

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:
