Adrian Edwards Posted August 9, 2010 Share Posted August 9, 2010 (edited) I had some requests for more photos in the Drotops Armatus thread, so here goes.. This is an extremely spiny Ceratarges Spinosus from the Devonian of Morocco. It has a pair of long, arching "horn" spines - both of which were prepared in a free-standing manner. The large eyes are on the ends of long stalks and have also been prepared free of matrix. A very unsual feature in trilobite morphology is that all four tailspines have a series of spines growing on the long spines. Please let me know if you'd like to any different type of photo of this particular specimen. Adrian.

Rover Posted August 11, 2010 Share Posted August 11, 2010 Well, a picture of the front of it would be nice. Great trilobite, though - the spiny ones are always nice to see, though probably a pain to prep. Link to comment Share on other sites More sharing options...

FrozenInTime Posted August 24, 2010 Share Posted August 24, 2010 Nice trilobite Adrian, this one definetly exceeds the majority you see from Morocco! Good going. Link to comment Share on other sites More sharing options...
Plantguy Posted August 24, 2010 Share Posted August 24, 2010 Hi Adrian, welcome to the forum! I'm really fascinated by the spines and the eye stalks especially on those dudes. Are there any details of the eyes themselves present? What an interesting adaptation! Also, it looks like you've got a couple of them? Is that right? In that 3rd set of pictures the 1st picture is a view from behind which appears to show one that has longer horn spines that cross the eyestalks and then in the 3rd picture the frontal view shows one with the horns that do not cross the shorter eyestalks. Is the latter a juvenile of the same species--or maybe is that just a variation within the species? It almost looks like the eye stalks had to grow laterally in the one specimen to see around the horns! Really strange, strange creatures....thanks for sharing.

Ludwigia Posted August 25, 2010 Share Posted August 25, 2010 Hi Adrian, Nice Trilo! I'd suggest you check out the latest issue of the German magazine "Fossilien". One of our Steinkern Forum Members has written an article about the preparation of similar Trilobites from Marocco. Here's a link to a thread about Maroccan Trilobites in the Forum: http://www.steinkern.de/forum/viewtopic.php?t=7144 Best wishes,Roger Greetings from the Lake of Constance.

The way the eyes and horns are formed do look quite different in the two photos you mention, but it's actually the same specimen. I don't know how to explain it better than being because of the camera perspective.

Jon (on behalf of Adrian) Hi Adrian/Jon. Been away for a while and forgot to punch the Watch this Topic button. Glad you liked the pics anyway. Too bad about the language barrier, cause there's lots of info there. Trilos are fascinating creatures. I'm so glad to have finally been able to have found some myself on my recent trip to Ontario. Best wishes, Roger. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
