Found this on the beach today... At first I thought it was a screw. Seems to be the stem of a Crinoid, but totally surrounded by this white, chalky, calcium like substance. What exactly is going on here? Also, I live on Long Island NY which I know is not home to any native fossils due to its geology, so are most limestone fossils like this basically washed here from other locations?

Hi, I found this interesting piece in my landscaping rocks. Am I looking at just a broken up rock or could these be possible impressions? First photo is one side and the others photos are the flip side Thanks in advance for any opinions

Found this in a stream bed in upstate NY near Ravena, NY. It’s roughly 12x6in. To me it looks like the flower of a crinoid but I am no expert so I’m curious to hear some opinion from this forum. Thanks!

This piece of Madison limestone contains a hash of crinoid and rhombopora. I initially thought this was fenestella but as I look at it again years later I'm thinking the geometry isn't quite right. Thoughts?

I'm a collector from michigan and have a large amount of specimens to prep. I am starting this topic to help others and myself on the ID'S of criniods and blastoids I commonly find in michigan. I'll start this with a worn, but otherwise nice criniod my sister found last summer up in partridge point. I believe it is one of 3 species of Megistocrinus. Im waiting for my sister to send me the specimen so I can get a better look at it and add photos to this post. I'm leaning towards an M. regularis due to its shorter height than the other two examples. Just under 6cm in length and width and a little over 3cm in height. Please share your thoughts on which one you might think it is. Any additional papers or resources on echinoderms is appreciated! Classification Common: criniod Kingdom: Animalia Phylum: Echinodermata Class: Criniodia Order: Camerata Family: Reteocrinidae? Genus: Megistocrinus LOCATION Country: U.S.A. State: Michigan County: Alpena township City: Alpena Latitude: 45.0056405 Longitude: -83.4332667 Geochronology Eon: Phanerezoic Era: Paleozoic Period: Devonian Epoch: Middle Devonian Lithostratigraphy Group: Traverse group Formation: Partridge point Member: Thunderbay limestone Dimensions Length (cm) 6 Width (cm) 6 Height (cm) 3.7 Notes Identifier Kyle Eichhorn Collector Kyle Eichhorn Event Date 02/01/2021 Field Notes: exposed by tides at partridge point park.

So I have this crinoid I wanted to prep with my new vaniman, but I am not skilled enough for this prep. I've done a couple crinoid calyx's and some with the arms, but this one has some fine detail showing through and I am worried I will destroy it. If there is anyone on here that I could turn to for help on this or any suggestions as to who to take it to would be phenomenal. The whole column wraps around the matrix. There are a few spots where the pinnules are showing. I have a terrible camera so I can only show a photo of the largest section showing. I'm not sure what species it is. Found on Partridge Point in Alpena. I believe the Thunder Bay Formation. Middle or Late Devonian.

Fossil hunting trip to Tontelange (Jurassic of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
On saturday I went on my first fossil hunting trip of 2021 with the BVP. Normally we would visit my favorite quarry "the Romontbos quarry" in Eben-Emael which is Maastrichtian in age, but due some complications that trip has been posponed till the end of September. Instead we went to the SETIM quarry in Tontelange in Belgian Luxembourg which was quite cool as it supposedly only the 2nd that this quarry allowed fossil hunting so everyone was quite excited. The rocks we hunted in this quarry are Jurassic in age, mainly Hettangian & Sinemurian. The lower levels of the quarry also had deposits of the Triassic (Rheatian) but those were not exposed at the moment unfortunately. But I had a great time at the quarry and I was very pleased with my finds. In a few of the quarry walls were used as nesting for sand martins (Riparia riparia) A piece of rock with the imprint left by a coral in it.

I was wondering who I would contact, aside from the property owner, if I had found a site that has something special. I would just like someone to look at a spot. I have never seen anything like it before. The area has never been cut or dug in any way as far as I can tell. There are slabs on the ground that have crinoid stalks in straight lines for 18-20 inches. There are stalks sticking out of the hillside. And not just a few. It is over 300 feet of creek bank with about a 2 foot layer of crinoid rich siltstone. I walked down the creek and in about 10 minutes I had filled all my pockets with stems. I am just curious what is at this site and would love to get someone to professionally take a look at the place. Who would I contact?

What would be the reason this stalk is so bloated?

sponge or crinoid? ... the way I am looking at is the small part is a stem?...and then the cup shape the other end?....or is the large cup shape is where it attached to something? and the small stem part is just that the base of a stem or it could be another miss.

Never purchased on of these. Just wanted yall's thoughts on authenticity. Are these commonly faked?
