Joe90 Posted January 29, 2011 Share Posted January 29, 2011 Brilliant trilos one and all, some real rarites here. Did you all do your own prep jobs? Can anyone point me to instructions on reducing photo file size as all my pics are 1Mb+ and I note that the pics posted are considerably smaller. Anyone help?? Mike.

As far as I know you need some kind of photo-editing software like PhotoShop or PhotoStudio, do you have anything like this? You will be able to crop and/or shrink photos, and when you do make sure they are no more than 900 or so pixels wide, and make sure your resulting jpegs are saved at highest quality.

piranha Posted January 30, 2011 Share Posted January 30, 2011 Morocco is famous for many unique gigantic trilobites. This is a Pradoella sp., a shovel-prowed homalonotid of the Family Calymenidae. Other notable homalonotids are Dipeura dekayi and Trimerus delphinocephalus of NY. Pradoella sp. 5.5" (14cm) Middle Ordovician - Morocco Ktaoua Sandstone Formation Link to comment Share on other sites More sharing options...
piranha Posted January 30, 2011 Share Posted January 30, 2011 Another infamous homalonotid is the "ELVIS" bug AKA Burmeisteria, Burmeisterella, etc., but is actually assigned as Scabrella propradoana. Elvis bugs are usually fabricated molds. This is a ultra rare 'real' example. Scabrella propradoana 8.5" (22cm) Lower Devonian - Morocco RE: Müller, P. (2005): Revision of the genus Scabrella (Trilobita, Lower Devonian). Geologica et Palaeontologica, 39: 1-27, Figure 1-13, Table 1-4, PL 1-4; Marburg.

2ynpigo Posted January 30, 2011 Share Posted January 30, 2011 One of my favorites. I picked up this trilobite from Horst Burkard at the Holiday Inn as part of my Denver Show trip. It is a Coltraneia outfatenensis from Morocco. Link to comment Share on other sites More sharing options...

piranha Posted January 31, 2011 Share Posted January 31, 2011 OK, I'll 'bite, why is it called the ELVIS bug? I'm not positive but the obvious analogy might have something to do with all of the Elvis 'sightings' of popular urban legend fame. If anyone knows how this Elvis got the nickname please tell us!

palaeopix Posted January 31, 2011 Share Posted January 31, 2011 Here's a couple more of my favorite trilobites. OK four specimens to be exact. They're all a spiny Pytchopariid called Irvingella major and come from the upper Cambrian McKay Group of south Eastern British Columbia. There's also a spiny Olenid that comes from the same area that is equally cool! I'll see if I can get a decent photo of one to show here. Link to comment Share on other sites More sharing options...
palaeopix Posted January 31, 2011 Share Posted January 31, 2011 (edited) OK so here's that spiny Olenid I mentioned before. It's called Aciculolenus palmeri and is also from the upper Cambrian McKay Group of south Eastern British Columbia. This one is only 6mm long and the largest they get is about 10mm. And here's another Irvingella major. This one is 20mm long. I love spiny trilobites!!!!! Edited February 4, 2011 by palaeopix Link to comment Share on other sites More sharing options...
Caleb Posted January 31, 2011 Share Posted January 31, 2011 Here is my personal favorite, the Cybeloides iowensis from the Maquoketa formation of Northeast Iowa. After finding this bug, I was hooked on trilobites. All the spines are natural to this bug, there is no restoration. This specimen was prepped by Gerald Kloc and photographed by T.E. Whiteley My other favorite is the Gabriceraurus sp. from the Platteville formation of Western Wisconsin. This specimen was found ventral and was flipped during prep. This specimen was also prepped by Gerald Kloc and photographed by T.E. Whiteley. 1 Caleb Midwestpaleo.com Link to comment Share on other sites More sharing options...

paleozoicfish Posted January 31, 2011 Author Share Posted January 31, 2011 (edited) I was taking a look at my soft-body ventral bugs and noticed that there really is quite a bit going on in their cephalon. There appears to be grasping legs, which is really no surprise. I just found it interesting. Does anyone know if there is any terminology for the various soft parts in the cephalon. One of the specimens seems to have a hypostome as well. Does anyone know how the hypostome was actually used or any theories would be nice. I also noticed that there appear to be sections of limbs in the rest of the body that function as units. Anyone have anymore information on this? The pictures should be detailed enough that they can be blown up a fair amount. cheers, PzF Edited January 31, 2011 by paleozoicfish Link to comment Share on other sites More sharing options...
frenchtrilobite Posted January 31, 2011 Share Posted January 31, 2011 WOw! I love these pyritized trilobites with soft tissues, I wish someday have one in my collec !

There are several great sources of information on trilobite ventral morphology, probably the best of which is Sam Gon's, A Guide to the Orders of Trilobites. Here's a link to the section on ventral morphology (http://www.trilobite...o/trilovent.htm), here's the link to the section on hypostomes (http://www.trilobite...o/hypoterms.htm) and here's the link to trilobite feeding habits (http://www.trilobites.info/feeding.htm). Another very useful source of information on the function of hypostomes comes from Richard Fortey, a world expert on trilobite life styles. Have a look at this YouTube video (http://www.thefossil...richard-fortey/), where Dr. Fortey speculates about how various types of hypostomes functioned. I hope these links answer all your questions.
