Permian Trilobite from so many pieces...

Recommended Posts

Hi all,

 

Im no paleo artist, but here is my one small step beyond stick figures drawing of what we got when we put together all the parts of the trilobite from the Fort Apache Limestone near Payson.  We never found a whole one, but all the parts from molts were eventually revealed.  While the major paper on the trilobites from 1960s listed the only trilobite found here was Anisopyge, we are not seeing this - I think it is Ditomopyge.  All three pygidiums found do not match anisopyge!  Anyway, here is my attempt at the recreation.  Ok, you can start throwing tomatoes now.

Looks very realistic! I'm no trilobite expert but it sure looks good to me

Great drawing! My only feedback is to remove the border around the thoracic pleurae. This border should only be around the pygidum.

 

The AMNH has a wonderful Ditomopyge that illustrates this point: https://www.amnh.org/our-research/paleontology/paleontology-faq/trilobite-website/gallery-of-trilobites/permian-period-trilobites/permian-trilobites/

That one looks great!

 

I attempted drawing trilobites a few times, but to no avail. They seem a lot easier to draw than they actually are...

Well, this is my first attempts ever at drawing paleo stuff.  Yeah, lots of mistakes.  the next drawing I promise will be more accurate!

Previously I pointed out to you that Anisopyge has a medial preoccipital lobe.

Ditomopyge also has this feature, absent from your specimens.  I would label it: Phillipsiidae indet.

Thank you Scott for your invaluable input.  I feel more confident now that I have finally been able to get a rough re creation of this enigmatic trilobite from the scores of small pieces we have collected.  With this new interpretation, and your highly observant advice, I will now go to my paleo page on this trilobite and update the new information and feel confident we have indeed a different trilobite than Winters had found in Memoir 89. (Anisopyge inornata).   Until we find a totally compete one, this is the best we can do at this time.  Thank you all for your helpful inputs, and helping make my very first paleo drawing a success!
