Our 3rd grader found this on a beach in Coos County, OR. Her first impression is that this is a snail fossil. We’re wondering 1) what is this and 2) if this is an internal mold? There’s also an impression on one side of the matrix that looks like a separate cast. But we’re really not sure… we are having a difficult time visualizing what’s going on here. When you look closely at the spiral it does appear to have shell in there. We’ve googled a ton and compared pictures of different spiral fossils, but still aren’t sure. Thanks for any info!

Last weekend I had the opportunity to spend a few hours collecting in a quarry in northern Illinois that exposes most of the Galena Group (Late Ordovician). There was lots of fresh rock to hunt through, and it was a good and productive trip. As usual, lots of gastropod molds were found. Hormotoma sp. Liospira sp. Sinuites sp. Lophospira sp. Subulites sp. Unknown gastropod. Looks like Liospira but appears to curl in the opposite direction. Brachiopods show up too. Most common are molds of what I believe are Rafinesquina (@Tidgy's Dad?). The inarticulate Pseudolingula iowensis is somewhat common. Specimens are almost always crushed and missing shell, but they usually have some shell preservation which contrasts nicely with the yellow matrix. Occasional bivalve molds are found. This one has calcite? crystals. Trilobite parts are uncommon, and the only species I've seen from this quarry is Thaleops, possibly Thaleops laurentiana. Here is a cephalon I found. Now for my favorite finds of the day. A partial specimen of the small receptaculitid Ischadites iowensis. Fisherites is very common at this site, but I had not come across Ischadites before. A partial conulariid. Judging by the visible cross section, the back side is present, so this should hopefully prep out nicely. And finally, what might end up being a complete trilobite. Not sure if there is any more buried, but it does look like at least some of the shell is preserved, so fingers crossed!

Three days ago, I made my first trip ever out to the St. Leon road cut in hopes of finding my first ever identifiable trilobite fossil. I had found only one trilobite before along the Ohio River, and much of it had eroded to where it was unrecognizable. St. Leon did not disappoint, even in spite of my cluelessness about which formation was which. After searching for awhile in the rain and beginning to feel discouraged about not finding a trilobite, I saw this fellow tucked away in a large rock. Unfortunately, I didn’t bring anything for scale, but the trilobite was roughly 2 cm across. I left the rock with the hopes of finding another trilobite that would be easier to take home. Just as I was beginning to trek back to my car, I found “Tilly” directly under my boot: It wasn’t a complete trilobite, but I was and am exceedingly happy with the features on this fossil. I left soon after for the day with this fossil in haul and a few others, which are included in the following images (it is worthy to note that in between my collection of the trilobite and my taking the picture below, I had done roughly 5 hours of prep work with a dental pick and a toothbrush): For the next time I post, I will certainly purchase a ruler or standard cm cube and find a better surface to place the fossils on, but this is all I have at home at the moment. I returned to St. Leon today with a similar objective as my first outing: trilobites. Once again, I was not disappointed. As you can see, these will need a lot more prep work than Tilly, but I’m excited for the challenge. I also found some other neat fossils whilst searching today: Overall, I am very happy with my trips down to St. Leon, and felt they were productive. For someone who is relatively new to the hobby, the road cut makes many types of fossils accessible in one small place, which is very neat. The area just requires cautious and careful movement, as much of the road cut is effectively cliffs of rock. If anyone feels the inclination to point out any genera or species of the fossils, I would greatly appreciate it, though I understand that the images I took are not of great quality. I know Tilly is a Flexi (F. meeki?), but that is admittedly the extent of my knowledge. Thank you for reading through this transcript of my journeys! P.S. I’m including another image of post-prep Tilly for fun. I tried to scrape more, but the fossil was just too fragile and kept breaking on me.

These specimens are from the Pittsburg Bluff (lower) formation - late Eocene. Given the body whorl differences as well as difference in penultimate whorl, suture, and apex/apical whorls (as much as one can tell from these specimens, I believe the Genus of the one on the left is Molopophorus. Any opinions?

Hello everyone, I am a new member and i do not understand much about fossil. Although i am very pationate about them. I found this fossil myself and i would like to remove the matrix attached to the fossil. I tried vinegar and a tooth brush. It kinda worked on the top of the fossil where you can see the tiniest spirals. That method cosumed about 2 days of work and only uncovered that tiny piece of the fossil. I am also concerned that the acid frrom the vinegarr will partially destrroy the fossil. What is the best way to do this? Best Regards, Bruno

Jv. Natica (Genus) from the Keasey Formation (marine deep water)
OregonFossil posted a topic in General Fossil Discussion
In Oregon Fossils by Elizabeth and William Orr, state that members of the Genus Natica live in a continental shelf environment. This specimen measured 8.99mm on the long axis of the image, and 7.39mm on cross section. Climate conditions changed from sub-tropical to temperate in between the Keasey and the Pittsburg Bluff formations. There is only about a 10% species overlap. The Genus Natica is still living today. I was unable to find a species ID reference for this specimen. I have found significantly larger specimens of this Genus in the Pittsburg Bluff formation. The specimen is partial shell and cast from the shell (basically the foot is cast).

Spring is almost upon the folks of Minnesota. There is still a bit of frost in the ground so 2022 collecting will soon begin. Until then, it is fossil ID time. This one is from Burlington, Iowa, the Burlington Formation, Mississippian. I have been looking at this one for a long time. Is it one of those predators of Burlington crinoids?? Is it a monoplacophoran? Species if so?
