piranha Posted August 18, 2011 Share Posted August 18, 2011 Hi Russ, Thanks for posting the photos of your giant homalonotid (Scabrella=Elvis ) from Morocco. To me it appears to be one of the better examples with most of the exoskeleton preserved. My vote would be that you acquired a complete individual and not a composite. The cephalon, thorax and pygidium line up just as they should. No problems that I can detect and the price paid for such a fine articulated specimen was an absolute bargain. Congratulations! Btw, awesome avatar change to the Olenoides! Link to comment Share on other sites More sharing options...

Btw, awesome avatar change to the Olenoides! Thanks, Looking at all the shell material and stuff I starting to thing that this is so. But having another opinion is good to have on this. I have been dealing with Doc Fossil and Brahime (sp?) for sometime on our Tucson trip and have found they have good material. We buy enough stuff for collections and one of the two fossil businesses I am in that they give me good prices on specimens. But I did wonder about this one.

trilobiteruss Posted August 19, 2011 Share Posted August 19, 2011 Hi on another thread in response to question I posted my best Ameura as examples to compare. Going to try to repost the thread here. Is there a way to cross post that I do know know about? anyway here goes: Ok here is the first 2 of my 4 best of my 6 ameura (with best cephalons). sorta also fits in the trilobite collection thread: Link to comment Share on other sites More sharing options...
trilobiteruss Posted August 19, 2011 Share Posted August 19, 2011 Here are other 2 Ameura: One more from same Iowa site: And finally one from MIddle Penn Strawn Group, MIneral Wells, Tx. Link to comment Share on other sites More sharing options...
piranha Posted August 26, 2011 Share Posted August 26, 2011 These two middle Cambrian Czech trilobites are interesting to consider as eyes have been 'lost' to the repeated evolution of blindness. The blind Conocoryphe (left) has sightless sister taxa that have vestigial or marooned eye ridges for example but without eyes that quite convincingly make the case. The sighted Ptychoparia (right) has been used in cladistic analysis as an outgroup in comparison to conocoryphids that demonstrates further the convergent nature of eye loss across many disparate families. Although the scholars concede that the methods are mixed with bias and error, still fascinating to contemplate the evolutionary process and relationships of trilobites.

Another world class trilobite Russ! Should be Pennsylvanian. I do have that one. Brezinski send me most of his reprints one time when I was doing some research on my two undescribed trilobites from the Lodgepole Ls in Idaho.

Plantguy Posted September 1, 2011 Share Posted September 1, 2011 Hey gang, so, I was moving things around again in one of the boxes in the garage and ran across my favorite trilo and thought about this thread.....it actually almost made me a bug person, (almost).... Anyways, this cant compare with the outrageous soft bodied, mind-numbing specimens or those sci-fi spectacular looking spiny things that seem to have more spines than my old dog has moles/warts (that aint easy to do), or all of the other crazy variant species, but, for a sweet $25 (US) almost 35 years ago I bought me what they told me then was a Phacops rana milleri from the Silica Shale in Ohio. I guess its now an Eldredgeops rana ...I still like the little rascal no matter what you call it. Here are a quick two views---measuring only 1.75in/4.4 cm's in length---it holds a very special place in my collection from the day it arrived in the mail. Some outrageous examples you all have! Thanks for sharing and educating! Regards, Chris Link to comment Share on other sites More sharing options...

Sinopaleus Posted September 1, 2011 Share Posted September 1, 2011 Haha...... yes, happy to accommodate that request! Attached is a spiny lichid trilobite from Morocco. As much of the Moroccan material awaits proper description, this one has simply been assigned over the years as the European equivalent type species; Ceratarges (Lichas) armatus (Goldfuss, 1839). Now in 2011 it has finally achieved a long overdue classification courtesy of Allart P. Van Viersen & Harald Prescher. Follow the link for the open access pdf paper of this and three other Ceratarges species. Always a pleasure to sort the Moroccan trilobites with specificity. Many folks need to make new labels! LINK Ceratarges ziregensis 2" Middle Devonian (Eifelian) El Otfal Fm - Jbel Zireg, Morocco so if ceratarges is lichas... does that mean i can find ceratarges in my new high school????!!!!!! btw, amazing specimen scott!!! :D Link to comment Share on other sites More sharing options...
trilobiteruss Posted September 13, 2011 Share Posted September 13, 2011 Hi, all. My favourite in my collection. Silurian trilobite Dicranopeltis scabra propinqua (Barrande 1846) Locality-Loděnice, Barrande´s pits, Bohemia, Czech republic. Silurian, Wenlock,Motol-formation,zone: Cyrtograptus lungreni, subzone: Testograptus testis. Photo 1-Before preparation (The original finding) Photo 2-After preparation Photo 3-Positive photo 4-Negative Awesome specimen, thanks for sharing. I love lichids....

piranha Posted September 13, 2011 Share Posted September 13, 2011 Spectacular trilobite and the extraction had to be a knee-knocker I bet! Did you actually find this one? I'm guessing that this bug measures around the two inch mark. I can see why you have declared it to be your favorite. Thanks for posting! Link to comment Share on other sites More sharing options...
Dicranurus Posted September 20, 2011 Share Posted September 20, 2011 1.Dicranopeltis is very rare lichid trilobite. 2.Because the second will never find. 3.The locality is inaccessible. Wow. That is a really nice lichid! "It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest.

piranha Posted October 15, 2011 Share Posted October 15, 2011 The trilobite posted recently by Kitron is definitely a tough act to follow. Dicranopeltis is certainly one of the rarer lichids but my favorite example will always be the classic Arctinurus boltoni from the Silurian Rochester Shale of New York. I waited patiently for a few years for a large complete specimen and this behemoth measuring in at six inches came up for sale from an old collection. The original label is still attached on the back identifying it from the legendary Ray Meyer Quarry in Middleport, New York. With nearly perfect preservation, pyritized pygidium and at the approximate maximum size for this taxon, it easily ranks among the very best. Enjoy!

Thanks Eric... if anything happens I will just send it to you! lol That will be the perfect time to find the next "old collection sale" Don't get too excited though, in the last 15 years it has not changed one bit!

piranha Posted October 17, 2011 Share Posted October 17, 2011 Congratulations. Very nice and very rare lichids trilobite. :bow: I like all lichids trilobite, i like N.Y Thanks Kitron! Since we both enjoy the lichid trilobites so much I will post my next favorite example. Listed previously as a Hoplolichoides, a friend and esteemed trilobite specialist recently suggested that this Russian specimen is best placed within the genus of Hoplolichas. By any name an incredible pincushion array on this super-spiny bug reminds me of an Amped Amphilichas on steroids!
