I've been a rock junkie my whole life. I can't help but look for minerals and evidence of organization in lithic form in one shape or other. It's a key for me to entry to learning about our world and reality. Thanks for letting me into this realm. What most recently brings here is that I have proposed and had the proposal accepted, to carve a gate based on the concept of crinoids found in the Shenandoah Valley of Virginia. As this is a fairly specific geographic area I was hoping some folks here might have some species specific information that might help me "flesh out" this concept to turn this functional sculpture into a bit of a learning tool. This will be carved from catalpa, assembled and painted. My website is https://www.sawaddict.com You can see some of my other work there. I hope to work more along these lines in the future. Hope you folks can help-Glenn

Hi! Please excuse us if we aren’t following decorum with our photo sizes, staging, etc. Since the quarantine has us unexpectedly homeschooling, we took our 5th grader to collect some fossils and though I’m sure they are pretty basic, I’m having a hard time helping her ID all of them. Any info is appreciated, as we are absolute beginners. ☺️ These were collected at a random roadcut in northern PA, another in West Virginia, and also at Beltsville Lake (where we searched all day for a trilobite until I realized I probably don’t even know what the fragments would look like).

Lots of ordinary things lately at Etobicoke Creek and Joshua Creek. Of course, when I began hunting in April 2019, I couldn't imagine finding such treasures, but there you have it. At the former location, we seem to have fun finding "How many decent-size orthocone nautiloids can fit on one rock," and the number appears to be 10 or 12 in some cases ! We also seem to be able to find snakes when we lift rocks, which can be disconcerting. Recently I noticed some unpromising "wavy surface" rocks, but they had a layer underneath with branching bryozoan fragments. Turns out, there are lots of them, and some are the largest chunks I've ever seen. So today I was out in the rain, getting muddy. I had to leave lots of great rocks...they were reasonably heavy chunks. Tree roots along the creek had split up the shales, pushed some promising rocks through to the forest floor, and dumped lots of slabs onto the creekbank. When I get some of these rocks cleaned up, I hope to post some pictures. Meanwhile, here is a group of recent finds.

Hello everyone! New to this site, and semi-new to fossil hunting. I have a 31 year old from Huntsville, Alabama and I have recently really gotten into all things earth-history after reading a handful of books that sparked my interest. I've always been interested in science, and natural history, but didn't find out until recently how interesting the whole story of life on earth is, and also how easy it can be to find these relics of the past right in your own neighborhood. Anyways, here's a pic of my beginner's collection. Mostly crinoid stems as they just fall out of the banks of waterways here. Also maybe some brachiopods? Thanks and happy hunting!

I found this piece of gravel a while back with a bunch of crinoids and the pygidium of a trilobite sticking out. Been curious ever since as to what the oval with the ridge running through the center and small hole in the middle is.

2 inch by 1/2 inch with Crinoids, Bryozoans, more and did not expect to see the 3/8th inch 0.9 cm pyrite on it. Allegan County, Michigan From my dig site Yesterday. I believe it is limestone. Would like the approximate age for the fossils and about when did the pyrite form on it?

The sun is exposed, snows melting, and many a birds chirping means it's nice enough to go scope out some Missouri Mississippian limestone! With the randomness of the weather this state gets, this is the first chance this year I've had to return to one of my favorite spots. This is one of many Burlington Formation exposures in Missouri. There are spots where the limestone consists of almost entirely crinoidal bits and pieces! Being the picky man I am, I mainly collect and prepare calyxs and brachs. Crinoids are king here, and will be by far the most common critter. They dominated the early shallow sea Missouri once was covered by. Its cool to see how many crinoidal bits some rock has just weathering away. There is about a good 12-16 feet (guesstimate) of the limestone currently exposed, much of remains underwater still. Eventually as time takes it toll, more pieces will weather, crumble, and eventually roll down hill. This area is constantly going above and under water. There is really no reliable time to hunt this spot, unless you know when water levels are low in the area. Rarely, one may find a nice crinoid calyx among the countless stems and other crinoid pieces. Usually they are pretty weathered like this one if they don't require any prep. Many of the calyxs found are just pieces, distorted, or crushed. It usually takes my eyes a hour or so before I can recognize calyxs quickly. I thought this chunk was cool. Its a heavily weathered calyx, with a small chunk of the stem at the base. I was shirtless today with it being the nice 60 degree weather. Seems Mr. Snake was enjoying it as well. That's all of the photos I got to take out at the lake. Finds coming soon when I'm home to take better pictures. I've only got a 30 minute drive from home, so here are the finds! I'll ID most of what I found later when I'm home with literature. I found a nice assortment of crinoidal calyxs, cups, plates, stems, and a few spines. Everything in the upper portion of the photo needs cleaned with some scribe/ abbrasive work. The rest should look good after I clean them with a pick, toothbrush, and warm soapy water. I also managed to pick up a nice rugose coral, a blastoid, a bryozoan, and a few brachiopods as well. March 3, 2020. My favorite find of the day And for those of you who like minerals, I found some nice calcite crystal as well. My favorite the honey color calcite Thanks for reading.

I found one of my most interesting and productive fossil sites ever east of Phoenix near Superior, Arizona in late November. The hill contained outcrops of the Devonian Martin Formation and the Mississippian Escabrosa Formation which is roughly the same age as the Redwall Limestone found further north. My first interesting find was several Pachyphyllum corals with very small corallites. The “craters” within the corallites averages just under 2 mm which suggested that these were the P. nevadense species which is not common in the Payson area further to the north. The coral is about mm across. I found a relatively rare Iowaphyllum nisbeti coral that was found by Gladys Nisbet, a botanist from the Phoenix area. The colonial coral is noted for its large corallites with prominent ridges in between. Coral colony is about 9 cm x 8 cm. Here is partially silicified Alveolites coral with very distinctive compressed fish-scale like corallite tops. This piece is about 65 mm across. Here is a nice massive Thamnopora coral 17 cm across. Along with the Alveolites were two types of stromatoporoid sponges. The first is an approximately 15 cm across Amphipora sp. with mound like mamelons. The second stromatoporoid has nice laminations with some vertical pillars. View is about 4 cm across. The most amazing find was several silicified calyxes of a blastoid and at least three species of crinoids found in the Mississippian Escabrosa Limestone. Interior and exterior molds of crinoids and blastoids are occasionally found further to the north in the Paleozoic rocks. Originals or casts are rare in Arizona especially when they are found in a few square meter area. This is the best spot that I have ever found for blastoids and crinoids. The largest and best blastoid was a 31 mm wide Orophocrinus saltensis that I have entered in the current Fossil of the Month contest. It was near maximum size for the species. I have seen no finer blastoid on the internet from Arizona. Cast your vote for the battle of the blastoids. I found at least three species of silicified crinoids. If you know what they are, please let me know. Species 1 is 11 mm across by 14 mm high. Species 2 is a cup that is 17 mm across by 18 mm high. Species 3 has interesting triangular patterns and is about 2 cm across by about 2 cm high. It is in a large rock that I need to break down so that I can carry it away. I planning on going back to the site to look for more goodies.

Hi, i'm Anne, hello everybody. I love fossils and also pareidolias. I'm here to learn and i'm sure to learn a lot from you. Nice to meet you people !

Hello again, I find these crinoid parts (I think) all the time and just want another opinion on what it is. I think number 1 is crinoid pinnules. Number two is the first and only one of these I've found so far here.(Mississippian redwall limestone, Mooney member). It's about 1/4 inch long and I'm guessing perhaps an echinoid spine? I appreciate any input you guys might offer. Thank you Bob

Hi guys, This is my first posting on the forum, constructive criticism is appreciated. Each year, when the water level in the lake is lowered in late fall, I go there in search of crinoids The first set of photos shows one of my better finds of 2017. This small slab (approximately 9 x 12 inches) had partially eroded from the shore. I was more than pleased to see all crinoids exposed along the weathered edge. Hopefully, there are some nice ones hidden in the center. Last year, while walking up a watershed near the lake, I found a slab of bedded limestone with the calyx pictured below. I decided to downsize the slab. The rock split along the bedding plane to reveal this: There were a couple of similar but smaller slabs nearby. I carried them back to the truck to split at home. I found one more nice calyx embedded in the rock. Pictured below are two more of last year's finds: While walking next to the waterline, I found the fragmented cephalopod pictured below. I was not sure if I wanted to keep it, so I set it aside to examine more closely on my way back. It was only after I looked at it again on my return that I noticed the tooth at the top. This year has not proven to be as fruitful as last year. The first photo pictures a calyx in somewhat rotten matrix. What should I use to stabilize it? One more Does anyone know the bryozoan to which the funnel shaped appendage pictured below belong? Thanks for looking

New Mexico - Sacramento Mountains; Mississippian Lake Valley Formation
Kato posted a topic in Fossil Hunting Trips
Mother Nature graced us locally with another temperate day so I had time to squeeze in a long exploration into some hidden canyons that comprise a large subset of the local Mississippian formation known as 'Lake Valley' To get to the canyons of interest I walked through Silurian-Devonian exposures but I did not stop to explore for anything. Here was my first view toward the hidden Lake Valley Formation canyons. You can see deformation from the mud mounding. More to follow.

Hi all, this fossil hash plate is like a super hard gray mud with cracks. Even using a wood rasp to smooth much off. Mostly a trial or training piece. The shell was broken and in layers, with much covered. I have removed a lot of the cover, can I get an I'd, and is it worth continuing? I also see two Brachiapods, and they still some material stuck on the surface. I do not know of a way to dissolve the matrix, to recover the fossils. ultrasonic does nothing.

Hi I was wondering if anyone could help me identify some of the key anatomical features of the calyx of this crinoid (Apiocrinites elegans) and any anatomical features of this brachiopod (specimen unknown). I have trawled and searched but am having limited success so thought there might be a fair few people that would be able to lend a helping hand on here! cheers mark

Hi, I pulled this Crinoids fossil hash plate out of a hill today. I may have seen the mystery in Lake Michigan mud stone, but not raised up or nearly as large. Ideas? Thanks. item is 4 in x 2 5/8th x 7/8th thick. unknown item is 1 in long x 1/2 inch wide.

I am back from my trip to morocco. It is a 14 days trip and I got 4 days for fossil hunting. It was so imagine, fossils are everywhere and even though I won't be able to dig, I still get plenty to bring home. Since my guide doesn't speak good English, I am not be able to ask him must so I need help to identify the fossil. On the first day, my guide took me to a place near Erfoud to search for dinosaur teeth. It is very close to the highway. We found a well that the local people dig to get Spinosaur teeth and bone. My husband went down to one but couldn't find anything because the well is new and it is not deep enough. We didn't want to try the deeper one so we decide to bought some spinosaur teeth from the local people there. This tooth is a little over 4.5 inches and I think there are some prepare but I can't tell how much. I also bought 3 smaller teeth and was giving the broken one which I don't know what it is.

Hi, I collected this inland in South West Michigan this week. I see lot's of Crinoidia byrozoans, and what looks like a horn coral. or possibly Evactinopora Bryozoa in limestone. . Please help with I'd, and a better age or time period? Thanks, Bob

It was raining this morning, so my best site was near Yaxley. The fossils really pop there when wet. In one hour of searching I had 13 fragments of ammonite. I thought it was 14, but when washing them realised one was a miffed snail, who is now in the garden. Mostly the ammonites are pyratised, and preserve sutures and ornamentation well. I found 8 crinoid sections, including round ossicles - I normally only find star shaped ones.

Found this rock in Highwood, IL, north of Chicago. I used to give this rock not much thought, just assumed I had thin wavy crinoid stem molds. Looking at it closer, I'm not so sure any longer. The stems seem to me to be too neatly lined up, as if the individual stalks had been cemented together when buried. Also, the individual "stems" don't seem to each have their own outer skeleton, unless the white vertical lines contain both of the adjoining crinoid skeletons but just appear as one. What's the likelyhood of that? What do you all think?

Recently, the opportunity presented itself to me to hunt for crinoids in the Burlington Formation of Des Moines County, Iowa. It was not a scheduled trip, but one that occurred because I in the right place but the wrong time. My mistake gave me a full free day to hunt fossils in Iowa (what a bummer!!) , so I headed out to look for some crinoids. The Burlington is so different than any rock formation that I usually hunt. It is made up of 90% crinoidal remains. It must have been a spectacular ocean floor to see!! I envision it to have been an undersea garden. Fossils other than crinoids do show themselves and I did pick up a few. First some brachiopods: A few corals. At least I think the larger one looks like coral. My doubts come due to its thinness. Trilobites are uncommon in the Burlington. This is the first trilo-bit I have ever found.

I attended an estate sale last week and the homeowner collected rocks. Sifting through the 50-cent box, I came across this specimen. It's not a complete crinoid, but the size -- and the size variety -- of the stems was particularly enticing. I haven't a clue about where she may have collected it, but the coral, brachiopods and bryozoan fossils in the box look like those I've collected in Michigan.

New member here. I am from central Indiana. The glaciers turned the northern half of our state into a flat pancake, and destroyed almost all the fossils. There are a few fragments locally, left over from when Indiana was a warm, shallow sea. I collected them compulsively since childhood, not much to look at. Just a bit south of here, there are layered beds of the former shallow sea, and excellent trilobites, horn corals, and marine shells. The shells wash out of the clay on the side of cliffs, and you can sometimes scoop them into a bucket, just like any other ordinary beach. I have boxes from that location. Due west, and there were low islands in the shallow sea, and clumps of sandstone can be found with beautiful carbonized imprints of ferns. The fern leaves turned into the thinnest layer of coal, and look like someone pressed them into a book. I have boxes and boxes of fossils I've collected over the years, as I was reminded when I swept out the garage last week. Yesterday I was kayaking on White Water river, and found a rounded scrap of coral, and an interesting molar tooth on a gravel bar. Looking up the tooth on the internet, I came across your forum. Glad to meet fellow rock hounds. I'm the only person I know who picks up rocks everywhere. My kids are used to it, but the rest of the people in my family think it's weird. Usually when I come back to the house after a walk my pockets are bulging with seed pods, fossils, or flint cores. I'll enjoy reading the posts here. Thanks for the photos you people have posted. Looks like the tooth is from a cow. I'll put it in my treasure box with the trilobites, beaver skull, and shed snake skin. Just read a few more of the posts here, and a 'burn test' was recommended. I applied the flame from a lighter to the root of the molar, and there is a very faint smell.

Fossil plate with echinoderms, making sure I found the correct tag.
nivek1969 posted a topic in Fossil ID
Hello. I have still been going through boxes of mostly cave mineral from a large estate sale purchase, mostly consisting of cave minerals. The tags that remain are not attached to the pieces and usually scattered among many boxes. This amazing plate I found recently and believe I finally found the label. I just need justification. I haven't found any other plates like this one. It's stunning in person!
