I already had 2 little piles of worm tubes then I found this larger single one today and appears the tube broke and exposed the worm. Examined the smaller ones more closely and noticed they have pyritized insides and cracks like on shell, started to wonder if they were gastropods, I see shiny spots and know the worm isn't preserved and tubes aren't shiny so doubting if they are Serpulid tubes. Also see what appears to be apeture on larger worm, so what are they? Last picture is backside of large one.

Howdy. I found this gastropod in Comal County, Upper Glen Rose formation, and I'm drawing a blank. I'm unable to find any sources that show or describe a species with this ribbed morphology. Any help is greatly appreciated!

I found this piece outside Kansas City, Kansas. It was found with some other fossils from the Carboniferous (many shells). It looks like a cast or a mold? Maybe a really large Gastropod? Pictures attached.

So, I have been preparing this nice little gastropod. I have seen five other specimens that shared the same characteristics, but, unfortunately, some of them did not make it. Before I continued to prep this one, I was wondering if it is possible to roughly ID this gastropod. It would greatly facilitate prep work to have a good idea of its shape. All the specimens I have seen have had three whorls. The upper two whorl's ridges are almost absent, this has been consistent through all my specimens. The shape of the shell is coeloconoid. It was found in the Leighton Formation, Maine; which is Pridoli, Silurian. The pictures below are of the specimen under direct, then raking light. The third picture is the external mold under direct light. Thanks in advance for your help! @MikeR @Rockwood

This weekend I had the opportunity to spend a couple hours hunting in the Galena Group (Upper Ordovician) in northern Illinois. The Galena around here is mostly massive dolomite, so most fossils are preserved as molds. Mollusks dominate the fauna, especially gastropods, although other interesting specimens crop up from time to time. Burrows A large orthoconic nautiloid Fisherites are fairly common in some beds, although extracting complete specimens is challenging. Thaleops sp. Some better gastropod examples Interesting minerals can be found, such as these pyrite crystals. Fisherites On occasion, fossils with remnants of their original shells do show up. The most common seems to be Pseudolingula. The best find of the day was this conulariid. I have never found a conulariid in the Galena before, so it was quite a surprise. And that's all. Hope you enjoyed!

Hi all! This is another report from Oxfordian quarries in the vicinity of Moscow. Previous 1 (Peski) Previous 2 (Timonino) Peski again. If you read my fossil sites overview, you know that Peski quarry is a unique site where you could find lots of Carboniferous fossils, Middle Jurassic dinosaurs, calcitic Callovian ammonites and very good Oxfordian gastropods. The latter are the most numerous and easier to search for. My trip took place in April and was mostly a success with a good variety of finds

I accidently collected this one on a rock containing a bryozoan. The shell is 5 mm. tall x 3 mm. wide. it was collected from the Kanwaka Shale in Greenwod County Kansas. Does anyone have any idea what genus this one belongs in? Thanks.

Straparollus argutus seem to be the larger of the two species, also much more thicker in diameter when adult size. Common, maybe a bit less common than S. circinatus. -
From the album: Lime Creek Devonian Rockford Iowa
There are two similar species of Straparollus. Think of them like sundial snails. Straparollus circinatus seem to be the smaller of the two species and also the thinnest in diameter. Common. -

Bellerophon sp. Abundant. Look a lot like rams horn snails. -

Diaphorostoma antiquum Rare - very very distinct shapes, more like the freshwater nerites you find in pet stores. Only found one so far! There's some other smaller gastropods I hadn't identified yet. -

Naticopsis depressa Rare. Tightly whorled, like a giant bellerophon species. -

Reverse side of my largest Westerna gigantea. -
From the album: Lime Creek Devonian Rockford Iowa
My largest Westerna gigantea. Part of the shell is preserved, which is smooth and have no ridges. Compare to Turbonopsis and Floydia its more tightly coiled and lacks the ridges when shell are preserved. Uncommon - I suspect its more due to overharvested as I tend to find more juveniles than adults. -
Anyone help identify this? Its covered in gastropods or so I've been told. Is it considered a mortality plate?
