    Geode, crinoid(?) and a mess

    Hello everyone! Mr. N here, I teach elementary special education and my students and I found a couple things from the crushed rock from the retaining wall. Item 1: limestone (?) with what I believe is a crinoid calyx exposed partially and scattered crinoid arm segments. Not confident on this one I'm super new to this. (Calyx most visible in last image, what I think are tentacle segments are most visible in the penultimate). Please excuse the green lichen that I haven't cleaned off, I'm afraid of I clean it I will not be able to keep from trying to dig that calyx or whatever out immediately . ________________________________________________________________________________________________________________________ Next is a geode or inclusion of some kind that was buried in fill dirt. We cracked it open together and found crystal formations and varied rock. I am tentatively identifying the brown as some kind of calcite crystal as it is reactive with vinegar and in the general hardness range of calcite. However I don't know how to tell fossil from rock and it's just weird enough I wanted extra eyes. This is also from Crawford county. 3rd and 5th images in this set show what might be a very small fossil tooth or edge of a shell? It's at the 8.5cm mark in image 3 and 5.

    Help for Newbie with ID

    Would love some help on identifying what's in this rock. Total newbie here and found this site after doing an internet search. I found this rock that was left in the garden by the previous home owners. Not sure where it's from, but we are in Missouri so could be from this area. This looked similar to pictures I found on the web of crinoid stems, but these seemed smoother. Anyone know if this is a fossil or just some neat rock formation? Also, any tips on cleaning/preserving? I sprayed it down with the hose to get off the loose dirt. Thanks for all your help.

    Echinoderm plate

    From the album: Fossildude's Middle Devonian Fossils

    Echinoderm plate from Arkona. Possibly a crinoid calyx plate.

    Niobrara Chalk Mystery Find

    Found this fragment in a Niobrara chalk outcropping in southeast SD. Entire rock is about the length of a pen cap, clip included. It has some indentations on the top edge that I think resemble a crinoid imprint, but I'm obviously not sure. Back isn't pictured, but nondescript. Advice would be appreciated!

    A bunch of old collection unknowns

    Hello, Here are a bunch of old collection fossils that have me stumped...almost no info on provenance so tricky, but I'm hoping I can get at least a fossil identity for them if possible. There are 13 in total, here goes: 1. Crustacean/brachiopod steinkern? 2. Crustacean? Brachiopod? 3. Is this a coral? 4. No clue...thought orthocone but seems too thin? 5. No clue 6. Thought some sort of echinoderm but almost looks six-sided? Reminds me of a construction nut used for screws. 7. Some sort of brachiopod? 8. This seems like a trilobite pygidium, appears to be on a white block of matrix? Any guesses as to specific ID? 9. These seem echinoderm. The one with the protrusion in the center might be an echinoid plate, the rest crinoid plates? 10. I'm guessing these are echinoid spines 11. Looks like some heteromorphic ammonite sections. The one on the right with a double row of tubercles might be Nostoceras or Didymoceras? 12. I'm pretty sure these are Conulariids but does the preservation inform the provenance or ID further? EDIT: one more: 13. Orthocone? Thanks!

    Fossil found at Saltburn beach

    Hi all, I posted yesterday about an interesting rock found at Saltburn Beach and was informed it was crinoid stem sections. I also found this rock on the same day which appears to have some fossils in it? I’m wondering if these are also from Crinoids? They are only visible when the rock is wet. Thanks! - Eloise
  7. Hello, I came across this listing with no ID/locality info and poor photos, can anyone identify at least what it is? About 5 cm across. From what I can barely make out it has some symmetry and regularity in structure/patterning so I think it is indeed a fossil, perhaps a cystoid theca or crinoid calyx or even float bulb?

    Indiana crinoid? Brachiopod?

    Hello, Some help with another unidentified piece please. The seller's label is "Crinoid (?) - central Indiana, Mississippian ~340 mya", but I don't see any ossicles or radial symmetry. A flattened brachiopod perhaps? Measures ~2cm.

    Nautiloid or crinoid?

    Found in a culvert outside of fast food place. Paleozoic limestone of unknown age. Help!

    Fossil/mineral ID

    Sorry I’ve been posting a lot but it’s been so exciting finally being able to identify some of my mystery fossils! I got this out of a box of random minerals and fossils at the last chance mine in Creed Colorado but I think they might have been brought from somewhere else but don’t know for sure. My first thought was coral but don’t really know. Thanks ahead of time!

    Crinoid or something even cooler?

    Hi all! Please tell me this is more than a concretion! Edit to add location: Found in Lansing, NY. The matrix is a dark grey/black shale that breaks under it's own weight when I lift pieces and it breaks off into big chunks unlike thinner layered shale also in the area. I think I see crinoid stems and wonder if there are other fossils (Hallotheca acils ?) under a shallow layer of sediment making the cone shape appear to have rounded sides or is this something completely different (I think I've been finding nice molds of Hallotheca acils in close proximity to where I found this guy today). I hope to return tomorrow and find the other half to try and glean more information from the molded half. It was the only fossil in this piece of stone but I found two species of Rugosa and multiple species of Brachiopods in similar stones lying within a foot of it. It's delicate and I've wrapped it in wet paper towels and placed in a shallow dish with water. The entire item measures 2cm wide x 8 cm long. Thank you for your time

    Crinoid stems and calyxes ?

    Found on another creek walk this week near an outcrop of Moscow fm and Ludlowville fm. Could this be multiple Crinoid stems and possible a calyx or two? Was broken when I found it. Matrix is much harder than the brittle Moscow shale and a dark grey. Still working hard to decipher the many types of shale that I am finding in the Lansing, NY area. The orange spot (pyritized?) goes all the way through the stone.
  13. I'm not totally sure what I got here, some friends said the first few are Crinoid segments and a brachiopod, but aren't sure of the last one, I think might be another part of a Crinoid, but not sure. If so, how old could that make them? Any thoughts? I find them in flint, I believe.

    Found in my ‘crystal’ pile

    Any ideas??? I found these in what I refer to as my ‘crystal pile’. it’s an area in my new construction neighborhood in north east Bexar County, Texas. The soil in which I found these was a rich black that reminds me of Irish peat bogs. It’s rich, black soil with a crumbly texture. The crystalline structures some which I believe are also petrified trees and these mystery creatures all have an orange color (possibly due to the heavy iron deposits also in the area). The crystalline structures and these creatures were found beside limestone. I was digging for the beautiful crystals and found these. They stood out and I immediately thought one looked like an esophagus and the other like a vertebrae, although I knew they weren’t what they initially appeared to be. One which was like a half ‘ring’, appeared to have the same ‘ribbing’ as the one resembling an esophagus. The ribbed worm like one is about 4” long including the broken portion which laying in the ground with a part broken off .it’s about 1.5 “ high. The vertebrae looking one is about 2” wide by 1” by 1” high. The half ‘ring’ one is about 1.5” and the thickness if the ring is about .5”. any help is, as always appreciated!
  15. Hello everyone. As usual, I need your help with one of my finds. It seems this small rugose coral has a buddy. At first I thought the the tiny "bump" was just a bit of debris sitting on top of the coral. But now that it's enlarged, it looks to me somewhat similar to a crinoid. I'm not really sure though, I've never seen a crinoid preserved anything like this. Surely it's not part of the horn coral itself, or is it? Thanks to all for your input. Detail:
  16. Last week, I was walking along a creek in Indiana close to where nice crinoids are often found. There in the water was what appeared to be a nice crinoid crown. After snatching it out of the cold water, I placed it in a safe place for my drive home. After arriving back in Minnesota, I spent close to an hour trying to identify it. No ID was able to be determined, so I decided to photograph it and ask for help on the Fossil Forum. Here it is, and by the way, I don't need help anymore with an ID. The solution came to me as I was editing my photographs. I must be honest, I photo shopped the last picture as to hide the solution to it's identity. Now the real picture. And yes I am blushing as I post this, knowing I had been fooled and admitting it to the world. I better make an appointment for the Eye Doctor!!

    ID requested for fossil

    The seller purchased this at a flea market and I couldn't pass it up because it's odd...… I have no information on it, but hope it's easily identifiable to someone.

    Fossil help please

    Hi there, I've never come across a fossil like this one, it goes straight through a rock, the width being about 3.5cm. The diameter of the fossil itself is about 2/2.5cm. Found in Seaham beach, which is in the north east of the UK. So the North Sea. Any help greatly appreciated, I have a six year old who doesn't know why I dont know what it is Haha.

    Permian crinoid

    Hello helpful fossiliers, Help please. These fossils came from outside Moab close to the Colorado River, but on a high shelf. The river is not visible from this location. Roadside Geology of Utah identifies this area as Permian, as did a BLM paleontologist. They are from about 10-15 miles SW from Moab. The rocks are largely a red base (clay?) with a gray-er surface. These three pictures are actually 3 different locations on the rock, but I think (wonder if) they are the same life form. The first is about 2 mm long. The ruler shows a mm scale. You can see the cross section end of the item on the fossil closest to the ruler. The second is a round disc from elsewhere on the surface and the third is a connected series of round discs. My sense is that the disc and connect discs are crinoid segments. Is the first picture also a crinoid, or am I way off on all this? I can post additional pictures if anyone asks. Thanks. Tom
  20. I am using a deer calcaneum for comparison. From a creek in Dallas/Ft. Worth. Am I correct about the crinoids?
