Upper ordovician, Italy. Decalcified specimen (it means that you see the mould). Scale bar 5mm. These are 3 different specimens, but I guess of the same species. At first thought they seem a blastoid oral area (never reported blastoids from this formation). But, as 2 of 3 of these specimens are inscribed in a circle, I was thinking about a particular echinoderm stem mould.

Hello, I found these urchins near Jebel Hafeet in Al Ain, United Arab Emirates. I think they come from the eocene, but I am not quite sure. I forgot to add a ruler in the photos, sorry, just know the largest one is just under 4 cm long. I would appreciate any id's. I will also be posting a picture on the fossil preparation section of the forum to see if I can clean them up a bit.

Fossil hunting trip to Cap Blanc Nez (Cretaceous of France)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone, Last week after getting lots of recommendations from people I spend a couple of days at Cap Blanc Nez in France to look for some fossils. And while it wasn't to most bountyfull hunt I did have a lot of fun and I was very pleased with the little finds that I managed to do. We had very nice weather, it was sunny and the temperature was just perfect for fossil hunting, and the cliffs and beach (and landscape overall) were absolutely stunning. The fossils in Cap Blanc Nez date back to the Cretaceous and there are deposits from the Turonian, Cenoma -
Found this yesterday in Mason County, Kentucky in the general vicinity of Maysville where Ordovician limestone (Bellevue Formation?) is exposed in the roadcuts. Not an expert but hunted enough to immediately appreciate the rarity of the find. After some preliminary research and a tentative identification (Carneyella ulrichi) I seek an expert review and confirmation/correction. These animals seem to be sufficiently rare that a firm ID shouldn't be left up to an avowed un-expert ... who knows little about the differentiating characteristics of edrioasteroids (or even echinoderms) to do more t

Hello to all users! I found this little rock fragment (mudstone from the Tethys ocean floor I think) in a geosite at the Kozani-Grevena Geopark in greece .....I think that there is a fossil on it. Is it or not? And if yes what species is it? (Echinoderm maybe?) Thank you for your time!

This specimen was found in the Maquoketa Formation (Upper Ordovician) of Minnesota. My best guess is part of an echinoderm (crinoid or cystoid calyx?) but I'm not sure, I've never found anything similar. Any thoughts?

I had collected some fossils from Spring Branch, Texas from what I think is the Glen Rose fm near Canyon Lake and I'm wondering what all these little discs are. For some reason I thought they were called foraminifera but in looking on-line, I think that's not accurate. I'm not sure where I heard that these are called foraminifera. Perhaps someone told me that or, more likely, I misremembered something I read somewhere. In looking at Uncle Siphuncle's very, very, very helpful (Thank you. It's a must read!) pinned Comprehensive Guide heading this forum, it seems these little discs are calle

Nortonechinus primus a sea urchin - I suspects the spines is a bit more common than people thought but still rare. More overlooked due to its small size and resembles broken golf tees. -
I am hoping someone on the forum is familiar with Ordovician carpoids. i collected this specimen at a roadcut in Claremont Iowa. it is from the Maquoketa Formation. Any information on what species it might be would be greatly appreciated.

I found this fossilized sea biscuit a few years ago in Holden Beach, North Carolina. Curious what species it is, and the approximate age.

This fossil was found by a friend near Falls of the Ohio, so presumably Middle Devonian but who knows. The hollow elements are straight, with angular cross-sections, and seem to be organized in alternating orientations. Any and all insights appreciated. The coin is an American quarter dollar, about an inch (24.26 mm) in diameter.

Hey guys， I‘ve dug out some ’fossils‘ that I can't say for sure on a hill of Hubei Province,China. According to the local geological document,there’re exposed strata of middle Devonian and lower Permian around this area. There are some rocks with special patterns on it, which looks like trilobite and shellfish. On another rock, I can see a patch of dots, just like a tentacle of starfish. On this hillside, I also found some strange rocks in the shape of ’flat cylinder‘, with irregular patterns on them. I think it may be the remains of some kind of ancient creature.

Hi everyone, Sorry if this is a bit of a basic question, but I'm fairly new at this and seem to be finding conflicting information about what I'm looking for. I recently found a number of fossil urchins, and what I think look like will probably turn out to be shells enclosed in sandstone on a beach. Some are pretty clean and only have a small amount of sandstone adhering to them, but others are almost completely buried in the piece of rock with only little bits of the fossil exposed. I was wondering what the best way to remove the rock is without damaging the fossil? I've tried soaki

Asteroidea (starfish) from Ordovician of Pennsylvania
traveltip1 posted a topic in Fossil Hunting Trips
Saturday dawned a bit chilly, but the sun peeped out from lingering clouds to brighten a stellar day of fossil prospecting in the Ordovician bedrock of central Pennsylvania. We strolled along the limestone ground, like beachcombers peering in shallow shore waters, when my relatively newbie friend exclaimed, "That looks like a starfish!" Bingo...Indeed it was an Asteroidea. I'm guessing it's genus Urasterella, and I wonder how rare is this find. The specimen's longest ray is 1.75 inches (4.45 cm). Photos are the rock slab and a closeup of the mostly complete starfish, as f- 24 replies

Hello, Last saturday I had a trek in a mountain area in the northen Italy alps and I found this fossil (I'm not actaully 100% sure that it's a fossil, but I don't know what else could it be). It looks like an echinoderm fossil to me, but I'd like to ask your opinion about it. Thanks a lot, have a nice day. Oz

From the album: Delaware Fossils
So sweet! This is a very rare Cretaceous echinoid (sea urchin), Boletechinus. They are typically no more than a couple mm in diameter. This one is shown next to a pencil eraser. Most of the ones in the Smithsonian's collection come from sand and silt removed for the creation and maintenance of a canal, which exposed fossils well below the surface. This one comes from New Castle County, Delaware. -
Last month my dad and I took a four-day weekend trip to Western New York to visit some new fossil sites and to collect in the famous Beecher's Trilobite Beds. We had only once before been out to Western New York to collect fossils - a visit to Penn Dixie Fossil Park - so this time around we wanted to try out some different places that we had never collected in before. The trip was a lot of fun and I enjoyed putting my research skills to work in finding new places to visit. I greatly expanded my collection of Silurian and Devonian fossils and found quite a few things on my fossil bucket list. I

For the Columbus Day weekend my girlfriend planned a three-day trip down to Southwestern Virginia as a birthday present to me. The plan was to do a little sightseeing, go on some hikes, enjoy the fall foliage, and, most importantly, collect some fossils. Unfortunately Hurricane Delta had other plans for us. As the weekend approached it looked like the entire weekend would be soaked with rain. We tried to change our reservations, but we were not allowed to postpone. Not knowing what to expect for the weekend, we made our trip. Sunday was to be my big day of fossil collecting. It was also the da

Firstly, a big THANK YOU to @Jeffrey P for hanging out with me for the day! What a knowledgeable, generous, and all around swell guy! If you ever get the opportunity to hunt with Jeff, I highly encourage you to. Jeff and I met at around 8:30 am, and after a quick transfer of his gear to my truck, we were off. We first drove about 45 minutes south to the small town of Wax, to hunt the Upper Mississippian. Specifically to look for blastoids and crinoid calyxes that were known to be found in the area. As it happens, luck was with us! Unfortunately, I didn't take the fiel

Hello! This is an apparent “fossil” brittle star, looking much like those that come from the Ordovician of Morocco. However, these particular fossils are very often faked, and I have a strong gut feeling that this particular one has been carved into the matrix. What does everyone else think? For whatever reason that I can’t quantify this piece *looks* like a fake to me, especially due to the fact that it has a very distinctive obvious outline from an air tool, which often is a sign of carving, though that I’ve also often seen that done with genuine Knightia and such.
