fossilized6s Posted October 12, 2015 Share Posted October 12, 2015 (edited) I'm happy to report that the fossil Gods were kind. This is only my second trilobite hunt ever, and I found a gem. I also found some other things, some I know, some I don't. First I'll post the ones I know. I'm posting this in "Fossil ID" and not "Trip reports", because I have more questions than answers. A nice bit of Conulariid that goes through the matrix. I still need to finish the prep. Cephalopod Bivalve, gastropods, cephalopod A nice hash plate. Now down to my mystery items. These are all from the Ordovician period. Unknown Brachiopod #1 Big mystery item (eurypterid material???) #2 Big mystery item (this has the exoskeleton look of a trilobite) I was thinking a single lateral pleural from a very large trilobite.

fossilized6s Posted October 12, 2015 Author Share Posted October 12, 2015 #3 mystery item (gastropod?) #4 mystery trilobite bit(s) #5 mystery trilobite bit (I could not prep this anymore, it was getting too sticky)(this item also has an exoskeleton similar to a trilobite). Now for my BEST trilobite find so far! Can someone please confirm this is a Dolichoharpes reticulatus.

Rob Russell Posted October 12, 2015 Share Posted October 12, 2015 (edited) Your mystery items appear to be invert fossils from the Ordovician period. Perhaps you knew that.

Haha I wish I knew more about the Ordovician period. Does anyone know of a picture heavy book about the Ordovician period? ~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...
Fossildude19 Posted October 12, 2015 Share Posted October 12, 2015 Nice finds, Charlie! I believe your mystery trilobite item is a hypostome, maybe from an Isotelus trilobite. Can't wait to see what the rest are.

GerryK Posted October 12, 2015 Share Posted October 12, 2015 #2 fragment of Isotelus #3 free cheek of Ceraurus #4 The small piece at the bottom of the last picture is a hypostome of Ceraurus #5 hypostome pf Isotelus 2 Link to comment Share on other sites More sharing options...
Doctor Mud Posted October 12, 2015 Share Posted October 12, 2015 Nice find Charlie! How did you prep that neat trilobite cephalon? Sure looks like Dolichoharpes to my untrained eye, but some features appear different to D. reticulatus. I'll leave that for the experts though. I just compared and contrasted with some online images and noted a few differences. Picture from AMNH website with yours for comparison. Bring on the trilobite experts!

fossilized6s Posted October 12, 2015 Author Share Posted October 12, 2015 Thank you, everyone for the help. Doc mud, I prepped it with a needle and patience. This is broken up quite a bit and it appears to be different because of that, but I think it is the same if whole. ~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 October 12, 2015 Share Posted October 12, 2015 Dolichoharpes reticulata is correct. This monograph has a comprehensive description: Chatterton, B.D.E., & Ludvigsen, R. (1976) Silicified Middle Ordovician trilobites from the south Nahanni River area, District of Mackenzie, Canada.

fossilized6s Posted October 12, 2015 Author Share Posted October 12, 2015 (edited) Any thoughts on mystery item #1??? Maybe a large Ceraurus "tail spike" off the pygidium?

Palaeontographica Abt.A, 154:1-106 Dolichoharpes.pdf You were one of the experts I had in mind Piranha :-) I noticed in the monograph they used "aff." for the described specimens short for affinis or affinity to. I imagine I might be opening up a taxonomic can of worms, but what is intraspecific variation and when is it different enough to use aff. I guess this comes from examining variation in multiple specimens and noting differences in the species affinis that don't fall within intraspecific variation but haven't resulted in the description of a new species. Thanks for humoring the taxonomic curiosity of a trilobite newbie. Link to comment Share on other sites More sharing options...
FossilDAWG Posted October 13, 2015 Share Posted October 13, 2015 Your "unknown brachiopod" is a gastropod, probably Pterotheca. See here, you'll have to scroll down a bit. Don 1 Link to comment Share on other sites More sharing options...

Ludwigia Posted October 13, 2015 Share Posted October 13, 2015 Everyone else has beat me to the ids, but I probably wouldn't have been of much help anyway. Just wanted to say congratulations to your success on your new exploratory project. Greetings from the Lake of Constance.
