Help on identifying species, age, and region of this pelecypod found in Michigan, US?
Zippy.Shrimp.Feet posted a topic in Fossil ID
I recently found a large stone hosting many of these pelecypods. I assume this is a limestone, as it has a slight reaction to acid, and there didn't seem to be any other super identifiable fossils, aside from some possible crinoid remnants. Its hinge is located far off to the side. These were found from rock placed along the Saginaw River in a small park in Michigan, so I can't say they were naturally from this area, but are local to Michigan. The ones I found range in size from about 25mm to 57mm. I would appreciate it greatly if anyone has any insight on the possible species, geological age, and where they might have originated from in the state? Thanks in advance for any help that can be provided..thumb.jpg.6360f52d61816c80248b8c39c7192d1a.jpg)

Cretaceous bivalve? South Central TX, USA (I know this is a long shot)
Jiesen posted a topic in Fossil ID
Any thoughts on this? I know it's a stab in the dark, due to the small partial remnant. This is embedded in a large landscaping stone that was quarried in South Central TX, USA, almost certainly between San Antonio and Austin. So it's Cretaceous, for sure. It measures about 60 mm in length (house key for additional scale). What you see here is all that's visible, unfortunately. I appreciate the feedback!

I found this odd fossil jutting out of a weathered large landscaping stone, probably locally quarried from just north of San Antonio, TX. House key for scale. I'm thinking Inoperna? That same stone has lots of worm tubes and other little conglomerated bivalves. Thanks for any input!

Found on a beach walk near Port Townsend WA. Approximately 3.5" long with some enamel/varnish at the tip.

Quick Stops throughout Canada-NY, Focusing on Toronto
Isotelus2883 posted a topic in Fossil Hunting Trips
This week, I had an opportunity to make some very quick (>30 min) stops along the way to a conference in Toronto, and on the way back. 1. The first stop was in Montreal, pretty close to the hotel. It was an exposure of the Tétreauville Formation. A 20 minute stop, coupled with the fact that even fragments of shale had to be pried out of the frozen ground, and that the shale was mostly empty, made this not the most productive stop. I did manage, however, to find some trilobite fragments. Starting with some small shell-less Sowerbyella sp. And of course trilobite bits, negatives, of course because my luck is just like that. Flexicalymene senaria Cheiruridae indet.

Hi there! I’m working on a project and I’m having trouble ID-ing this specimen. I wanted to ask if anyone can identify this bivalve? It is from the Nashua Formation in northern Florida. This specimen is slightly larger than 5mm x 5mm Any assistance, even a family or sub family is appreciated!

I recently came across this specimen in a chalk cliff in Normandy, France, near the town of Livarot. I was wondering if anyone could advise me what it might be? Fish, or shell, or something else? In advance, thanks.

2 cm shell fossil found in Normandy chalk cliff. Any ideas?
Philip Ogley posted a topic in Fossil ID
I recently came across a fossilised shell in a chalk cliff in Normandy, France, near the town of Livarot. There were other shells and invertebrates, but this was very clear and beautiful. It's only about 2 cm wide, and I was wondering if anyone could advise me what it might be? In advance, thanks.

I was at Atwater Beach at Shorewood, WI for a couple of hours today because a cursory online search showed that it’s a place where people have supposedly found Silurian Reef fossils. I did not find anything of note except this rock that looks like a bunch of clams fell on wet concrete. I’m only second-guessing myself because the beach is littered with tiny mussel shells, as well, and I know it would not that that long under the right conditions for bivalve shells and sediment to become squished together into one mass. I have found some rocks that definitely looked like that. But, this one is much heavier and I only see what looks like indentations, not the shells themselves. Not to mention, the patterns on the ridges do not look like those of the native mussel shells that litter the beach. The second picture is the back of the thing.

Here is a quick and (hopefully) easy question for all you Penn Dixie (New York, Erie County) or bivalve experts out there. In going through some of the material I collected last summer, I came across this very nice, but small (1.1 X 1.0 CM) bivalve. It looks most like Lunulicardium eriensis figured on page 160/161 of Wilsons Field Guide to the Fossil of New York. But the book lists it as from the Upper Devonian Canadaway Group and I can't seem to find any reference to it (after a quick search) from the Middle Devonian Moscow Group present at Penn Dixie. My question is: is my ID incorrect or did I just not dig deep enough to find reference to it from Penn Dixie or the Middle Devonian? Thanks for any help. @Fossildude19 @Kane, @Jeffrey P and any others.

From the album: Invertebrates
Typhloesus wellsi Melton & Scott, 1973 Early Carboniferous Serpukhovian Heath Formation Bear Gulch Montana USA In the beginning, it used to be believed that Typhloesus were conodont animals, a group of extinct agnathan vertebrates. The conodont teeth however were actually located in the gut contents of the Typhloesus, meaning that while it wasn't a conodont, they were a part of its diet. A new paper published revealed several potential mollusk-like features of the animal. -
Good morning! Asking for help identifying 3 fossils (two on one rock) found in riverbed in Val Verde county near Del Rio, Texas. The first 4 images are of one rock with two features. The shell imprint might be a Pecten Texana bivalve (from online fossil ID site)? The other feature might be some form of sponge like the family Clionaida?? Both features are covered with fine crystals giving a lovely glitter - any thoughts on how/why that process happened? Final three images I think are a random rock, but the shape does mimic an image online of a vertebrate toe-claw of some sort, so curious about this. Thanks in advance for any thoughts!
