Trilobite ID

Recommended Posts

Ramon

I bought this fossil today at the Houston Museum of Natural Science. I want to know the genus of trilobite and maybe the species. It looks like Phacops. It is in a defensive pose. In total from the glabella to the pygidium is 6 1/2 centimeters. Any help would be appreciated!!!

 

Glabella

I agree it does look like phacops (or Eldredgeops) but I am not an expert could you get a close up of cephalon and one of the pygidium if it is exposed?

Unfortunately the Pygidium is not very well preserved.

Here are a couple pics of Eldredgeops rana that I collected from Deep Springs Road. I have one small complete enrolled one as well but it is to small for me to photograph well.I think mine and yours look the same.

Well I think it is Eldredgeops rana.

 

Thanks for the information.

The trilobite is from Morocco so it is definitely not Eldredgeops.  Barrandeops or Boeckops are the common Moroccan phacopids.

As I mentioned to you previously; eye lenses need to be counted.  You need to present a photo like this to determine the species.

The eyes aren't very well preserved in this fossil.

To me it looks like Barrandeops.

Without the lens files it is not possible to ID this trilobite. Boeckops also has similar tubercles on the glabella.

The morphology and lithology are typical for these.  Do a Google or ebay image search for comparison.

And It's very common that they come from there. Today more than 50,000 Moroccans earn their livelihoods in the fossil and mineral specimen mining and export business.

I'll just label it Phacopidae Ind.
