fossilized6s Posted July 9, 2019 Share Posted July 9, 2019 @piranha @GerryK Can anyone confirm this is Paladin transilis? I found this in the Carboniferous of Illinois. Not sure if they've ever been described here...... And yes it's preserved in pyrite. 8 ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

piranha Posted July 9, 2019 Share Posted July 9, 2019 Very nice colorful find! Paladin transilis is a Russian species. "Carboniferous of Illinois" is a broad term, what is the formation? This specimen has a median preoccipital lobe and pygidium that matches key features for Ditomopyge. 2 Link to comment Share on other sites More sharing options...

It's still unclear what formation this is, because there aren't any papers that i know of on this site. But i believe it is the Carbondale formation. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Was there a shale member above or below that you noticed? A coal seam? Limestone? You see what I'm getting at, right? Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

You see what I'm getting at, right? Glacial deposit, then gray shale (trilo layer), then black shale, then limestone. That's why I'm leaning towards Carbondale. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

deutscheben Posted July 10, 2019 Share Posted July 10, 2019 Wow! Those are stunning. I have found trilobites in the Pennsylvanian La Salle Limestone member of the Bond Formation in La Salle County, Illinois that look similar, and the guidebooks list Ditomopyge and Ameura as the only two genera present. 1 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted July 11, 2019 Share Posted July 11, 2019 The genal spine seems a bit on the short side to be the specie you mentioned in the OP. I'm getting better at trilos and I'm not even trying. I hold this forum responsible for that phenomenon. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

The species (species is singular and plural) frequently seen on the internet labeled as Paladin transilis is actually Ditompyge producta.

Only the images showed it at least twice the length of these drawings. Not necessarily. There is a mix of legitimate and illegitimate/irrelevant images available on Google. Keep in mind that the images supplied are based on what the bot crawler finds, and may include mislabelled information, or tangentially associated reference (a search for a specific trilobite yielded a picture of my friend that might have appeared on a site referencing the trilobite). Ideally, going to peer-reviewed academic sources is the gold standard, but some of the images referenced in a Google image search may include those. Navigating the images search requires some skills in curating information, and this remains true of anything found on the internet. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

The genal spines are variable depending on the species. Figure 5a from the Treatise on Invertebrate Paleontology is Ditomopyge scitula. In comparing the Russian species of Paladin transilis and Ditomopyge producta, besides the absence of a preoccipital lobe, the genal spines of P. transilis extend only to the 7th thoracic segment. The genal spines of D. producta extend considerably further down to the pygidium. 3 Link to comment Share on other sites More sharing options...

Trilobites are somewhat complicated. It may be due to faunal provinces which account for the variation. This will account for some allopatric speciation. For example, the faunal range for a Ductina vietnamica might have been broader than, say, a Coltraneia oufatenensis. And, yes, trilobites can be complicated... but so, too, can be the most intriguing romances! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
