I recently chiseled this piece out of a Mississippian road cut exposure in north Tn, Fort Payne Formation, with a generous assist from TFF member @Herb. I apologize for lack of proper scale, measuring approximately 6cm x 7cm x 5cm x 10cm. I used a dremel, soaking, and scrapping method to remove as much of the hard limestone, but cannot remove the rest as the dremel bounces off the solid crinoid hash remaining. I am having difficulty with identifying where this would fit on the crinoid unless it is something similar to the proximal stem and branching arms shown on the illustrated figure by Ausich, W., Brett, C., Hess, H., & Simms, M. (1999). Crinoid form and function. Fossil Crinoids. http://paleoinver.materias.gl.fcen.uba.ar/index.php/download_file/view/106/129/ I appreciate the help! Thank you, Leah Bottom Front (for reference) Side Top

I while back I acquired a collection of fossils,minerals, and rocks. They were apparently found at an estate sale before being bought and sold online, hence the prices on the labels (not what I paid for them). It was rather large and confusing, but I managed to figure a lot of it out. One bag, however, has crinoid and blastoid stems and calyxs (calyxi? Calyxese?) and six labels, none attached to the specimens. I was wonder if y'all could help me sort them out, because I'm confused. A few of the labels are just "crinoid stems", is it possible to get a better ID on them? I can take more pictures if needed.

Here's a crinoid I found the other day in the Menard Limestone (Chesterian series). I'm not so sure of what genus it may belong to.

A TFF Gathering in an Upstate New York Middle Devonian Paradise
Jeffrey P posted a topic in Fossil Hunting Trips
Yesterday was a planned get together of TFF member friends at one of my favorite Middle Devonian localities- Deep Springs Road in Madison County southwest of Hamilton. It is the easternmost exposure of the Moscow Formation and the Windom Shale- the same formation exposed at Penn Dixie- but a very different faunal content. Biodiversity is the primary feature of this site and this outing added to an already long species list. This trip was actually a long time in planning. Frank (frank8147), a long time collector in New Jersey's Cretaceous streams, had been expressing to me a desire to visit Upstate New York and try his hand at Paleozoic collecting. He told me he and his girlfriend were planning a trip and once we were able to set a date- which was right on the heels of my own trip to Germany, I decided to invite a few other TFF friends. Tim (fossildude19), Dave (Darktooth), Diane (Mediospirifer), Dom (Dsailor), and Tony (njfossilhunter) were able to make it. Tony and I drove up together. Thanks Tony for all of that driving. Dom and Frank were new to the site. Tim and Dave brought family members and a good time was had by all. A rain shower in the middle of the afternoon drove some away, Diane and her husband, Tony, and I remained and I made most of my best finds late in the day. Here's a few pics: Here is (left to right) Dave, Tim, Tony, and Dave's older son.

Trying to get someone to lead my wife and I in the right direction for a good day of fossil hunting. We live in the Knoxville/Oak Ridge area of East Tennessee. Any directions to good sites would be greatly appreciated. Any good prospects in our area? Thanks guys!!

Two questions here, what are general things to look for when deciding whether a fossil is fake or real? Guidance asked for especially when it comes to Moroccan imports, and mosasaur anything, crinoids, and trilobites, as well as pleistocene mammal fossils. The latter question, is there any massive list of information sort of like an identification guide for fossils? I saw this massive list fruitbat had and its very impressive and I shall put it to use, but i feel it's almost a little bit beyond me at certain times, is there any just general all encompassing guide to identification?

This may be a long shot, but here are a couple of crinoids I picked up at a roadcut near St. Louis. They aren't in the best condition, but they were a nice surprise. The roadcut exposes a portion of the Valmeyeran series (Mississippian).

Hey Guys, family member are going to meet up at Sodus Point, NY for an outing during June 7 thru June 11. Sodus Point is located on Lake Ontario east of Rochester. Although I know of some fossil hunting locations in upper NY, they are all located around Buffalo. I would like to take my 5 year old niece out on a fossil hunting excursion. She is well on her way to being a rock nut and wants to be the first paleontologist on Mars. Love it. If any of you guys know of some productive sites that would be kid friendly and would be willing to share the location(s) it would be greatly appreciated. If you'd like PM me. I am aware of the Penn Dixie site, but that may be too far to go. Thanks )s

I found several mixed pieces last weekend while out in southwest Virginia; bits that had tumbled down the hillside and into the road. This was along a road that follows the Holston River, in mostly limestone/shale. One piece was filled with crinoids (stems), from tiny to pencil diameter; one had meshy bryozoan pieces and brachiopods, then there was the piece that had this. Please bear with me, I've looked online, and in my books, but since I have no idea what I'm looking for, it complicates things, and I want to learn. In both examples, the coral-looking chamber/pore sections are alongside the mesh/bryozoan-looking sections, so I'm not even sure if I'm looking for one, or two separate, organisms. I'm sure whatever it is, it's probably very common in this area, but if someone could help ID it so I'll know next time, or at least point me in the direction of what I need to research, I'd be grateful. Thank you!

Hello everyone! I found this site because my son and I are constantly picking up rocks from our property with little fossils in them. Cool site...I look forward to chatting with you all!

Last week, after checking the weather wunderground numerous times, I decided to drive 3.5 hours from Chicago to St. Paul Stone Quarry. It was the last "open house" day according to the ESCONI website. I arrived at 7:45, the first and only person there. Shortly thereafter, after a brief safety instruction, I followed the manager to the collecting site, heaps and heaps of Waldron shale. Even though I dressed in layers, I still had to take breaks and warm up in the car for a few minutes, but I much rather prefer collecting in cold weather as opposed to hot summer sun with mosquitoes, any day. It didn't take too long to start finding fossils. Here are just a few of my finds: Eospirifer Platystrophia brachiopods with pyrite Platyceras niagarense encrusted with strophomenid, bryozoa and pyrite. front: back: Partial Dalmanitid Trilobite in matrix When prepping, it's really wonderful how the waldron "butter" shale just crumbles apart around the predictable morphology of an enrolled trilobite. The trip just wouldn't seem complete without a short drive east to the Cincinnati Arch roadcuts. I first went to South Gate and found a flexicalymene eroding right out of the cut. It is interesting to see the comparisons here. The trilobite on the left is from St Paul (Silurian) and has beautiful pyritized eyes. The one on the right is from South Gate (Ordovician). Both trilobites have 21 articulated segments; does this make them both the same age as "adults"? Interesting to note the difference in size, being 40 million years apart, same species.. Thanks for looking!

Hi everyone, I've no exact location for this crinoid fossils, only just to say they are from the UK. Although there is some obvious crystal on the reverse and around the side if that's any help. Any additional help will be gladly received.

New project I'm working on prepping. I grabbed this plate from Penn Dixie earlier in the season, and it's just loaded with bits of all different things. I've taken it on as a long term projects to prep out this section as best as possible exposing as much as possible. I don't have an actual before photo, because I didn't think it was worth photographing until I started playing with it. I will keep updates as I go!

I have what I think are somewhat technical questions for those more knowledgeable than myself. Wandering the wonderland that is the Wilson Clay Pits of central Texas, you tend to run across numerous examples of these fossils... The above photo shows only one side of the spines. The other side is smooth... In the University of Texas Bulletin #2132 Stratigraphy of the Pennsylvanian Formations of North-Central Texas (1921), Plummer and Moore have them identified as Hydreionocrinus sp. spines. So, for my first question, is Hydreionocrinus still a valid genus? If not, what is the new name? While I knew that they were spines, I have been confused by the placement on the animal itself. I had seen reconstructions of Delocrinus sp. with the spines radiating from the top of the cup. But these looked different. I then stumbled across a paper from the Ohio Journal of Science called TEGMEN ROOF OF PLAXOCRINUS MOORSI (WHITFIELD) by J.J. Burke. He describes very similar plate spines on the tegmen roof of the anal sac of Plaxocrinus sp. Below is the figure in his paper that caught my attention. So, I tried a quick sketch of what I thought Hydreionocrinus might look like. Am I correct in assuming the spines are located at the tip of the anal sac? I'm guessing that the textured plate surface is attached to the sac. Is there a complete Hydreionocrinus calyx that I could look at (I'm kinda visually minded...)? I'm sure the drawing is out of proportion. I was drawing from memory and imagination more than anything. It could be a crinoid chimaera... Your comments are welcome and appreciated...

Incredible 3 Generation Fossil Hunt with LOTS of Pictures!
Bev posted a topic in Fossil Hunting Trips
This was a truly incredible hunt. Please be patient with me as this will take several replies as there are LOTS of pictures and a story to tell. I will say "The End" when I'm done. :-) This was a private hunt booked through the Eagle Bluff Environmental Learning Center, Ecotours, for three generations of the same family. They were experienced fossil hunters and it showed! I'll give you a teaser of the TWO best finds! Praecupulocrinus conjugans as IDed for crinoid expert Crinus in this post: http://www.thefossilforum.com/index.php?/topic/66595-beautifully-articulated-ordovician-crinoid/ AND A beautiful whole trilobite from the Decorah Shale which I believe to be an Anataphrus borreaus, that is what we usually pull out of this site, but it needs more prep to be sure. Read on for the WHOLE trip report... It was a beautiful July day in southeast Minnesota for fossil hunting. Temps in the 70s, sunshine, a breeze, low humidity and we had just had two torrential rains that washed out a whole new batch of fossils. The bluff country if SE MN is part of the Driftless... http://www.bluffcountryfossils.net/blog/mysteries-of-the-driftless-video/ and considered one of the most beautiful areas in North America - and very fossiliferous! The Eagle Bluff bus arrived and we started out with about an hour tour at my place, Whispering Winds in Spring Valley, of the fossil gardens and fossil prep barn. With three children ages 5-9, I set up my dino area and showed them a young pigeon as an example of what a baby dinosaur may have looked like as all birds are descended from the dinosaurs. Thanks to the generosity of TFF members I was able to give them a REAL dinosaur bone collected in Wyoming and fossil shark and stingray teeth collected in Morocco. And they had a blast in the fossil sandbox fill with St. Peter Formation sand, fossils and minerals. Then off to Masonic Park which too me is the perfect fossil park! This limestone cliff shows the Prosser and Stewartville members of the Galena Formation wonderfully. A branch of the Root River runs below the cliff and not only Ordovician fossils but also Native American artifacts and Ice Age fossils (mammoth teeth) have been collected here. It also has a cave, an abandoned quarry, and even a hidden stream coming out from beneath a bluff with great fossil hunting on both sides of the road. Hunting the roadside ditches. From there we went to a lovely long road cut that includes both the Stewartville and Prosser members of the Galena Formation. Continued...

got this slab of fossilies here theres plenty of crinoid, but also some other little peices. they look to me like the front shape of a trilobite. there are no other trilobite signs on the slab other than these. am i correct in saying these are the front peices of trilobites? just asking for future finds. thanks! heres a seperate gastropod that i didnt actually take home. Still new to this whole forum thing. Working my way through highschool, and hopefully into a college or something and into paleontology. Thats the dream, anyway! idk im rambling.

My son (12) and I are going back to my home state of Wisconsin for a trip this week. Can anyone point us to a few spots that do not need permission to collect, or provide the names/numbers/places of the good places? We will be in the Madison area for several days, and then north to near Phillips (side trips okay). Nik wants to be a paleotologist and the fossils here in California are few and far between relative to WI. Your help would be greatly appreciated. I want to continue his interest in fossils, but it is hard to peak their interest if you can't find anything!

I have had my nose in creek rocks since I discovered my first crinoid stem at a camp in Fairview TN when I was 8. Back then I thought it was indian money, but now I know that it is an even better treasure from the past. Currently my collection is composed of crinoids and rugosa corals, but I hope to find many other sea species. I continue my modest creek digging and hope to share my finds with you all and hopefully get help when I can't identify something. Attatched is a photo of the stems and segments I found as a kid. But I have many more fossils where those came from and will love to share in future posts. Thanks! -Alexandra
