I've wanted one of these Moroccan crinoid blocks for ages, so I couldn't turn this one down when I was able to get it for £10 ($13 US). All I had to go on were some poor quality images and I had no idea how big it was. (it's 10 inches across at the widest point). However, because I've never handled one of these before, or seen one in the flesh, I don't really know what to look for in terms of fakery, compositing or restoring. It does have a really horrible surface, making it look like plastic - I'm hoping this is just some sort of thick, ugly substance that has been applied to consolidate the surface, since it doesn't appear to be a cast. I'd be grateful for any opinions, or suggestions of what to look for. Sorry the photos aren't ideal - I tried it outdoors in natural light, and indoors with flash, but the horrible surface made it difficult to photograph well.

Good Bye to my Crinoid Avatar
crinus posted a topic in Partners in Paleontology - Member Contributions to Science
Yesterday I signed over my prized crinoid (my avatar) along with 20 other specimens to the University of Michigan, Museum of Paleontology. With this crinoid I donated 7 other prized crinoids, 2 blastoids, 4 Tully Monsters, 2 brachiopods, 1 Mazon insect wing, 2 corals and a Cooksonia. These will then be loaned to the Museum of Natural History to go on permanent display in the new museum to open in 2019. Hardest part was parting with my avatar crinoid. It is what I consider the finest example of an Arthroacantha from the Arkona Formation at Arkona, Ontario. Not that parting with 4 exquisite Tullys wasn't hard. Hey, I offered and they came and took. I just wanted the museum to open with very nice examples of fossils.- 21 replies

I found this a couple of years ago and have periodically taken it out to examine it as I've found the accumulation of fauna adhering to it's surface as very interesting. For awhile I affectionately referred to it as an accretion (as opposed to a concretion), envisioning a clump of mud rolling around in the wave action of a shoreline picking up bits of dead fauna. But now, with the fairly recent posts that have come up about crustacean burrows, I'm second guessing. On the exterior of this piece are brachiopod shell bits and molds, possible pectinid shell molds, crinoid columnals, and tiny gastropod steinkerns and exterior molds with decoration. The dark clumps appear to be pyrite. There are two depression areas, one on the large end, and a smaller one that is offset of the smaller end. These I speculate to be the exposed chamber, should this be a burrow. Notably within these depressions are oval shaped pellets and an interesting fibrous texture. So, I now defer to your opinions! Thank you for looking!

My crinoid collection on the web was updated and expanded by many background informations. So enjoy it, if you like that stuff: http://www.fossilcrinoids.com/gallery.html Any additional informations or publications to the described classic crinoid sites for upload are appreciated - please give me notice. Please feel also free to contact me in case you like to offer crinoids, that I am (most) missing in my collection (see "Bid") - thanks! -
Hello guys and gals, I greatly appreciate this forum and thanks for welcoming me. I have a set of 4 teeth that I only know that are from Florida. I’m thinking Carcharias but I’m a noob so I’m not confident. As far as the crinoids, I got them as a “gift” after purchasing a tooth from a dealer. All he knew is they were crinoids from Dakhla, Morocco. I’m guessing Pennsylvanian? Any information would be awesome. Thanks guys/gals

From the album MY FOSSIL Collection - Dpaul7
Fifeocrinus Crinoid Arms SITE LOCATION: Chesterian Zone of the Bangor Limestone Formation in northern Alabama TIME PERIOD: Mississippian Period (ca 325,000,000 yrs old) Data: Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults.

Hi. Around year ago I was exploring the area around Lough Hackett 20 km north from Galway. I found few fossils on the shore with much different fauna than typical late Visean fauna in Co. Galway. The main problem here is stratigraphy. It's similar to british Avon group of Mendips. I think all of them are Tournaisian. Fig1. Large piece of iron-stained black crinoidal limestone.

Solnhofen fossils/ Polish ammonites for exchange
Kasia posted a topic in Member Fossil Trades Bulletin Board
Dear Forum Members, I will gladly exchange Solnhofen fossils (there are several floating crinoids plates of different sizes, coprolites, aptychi of ammonites) and Polish Oxfordian ammonites (from Ogrodzieniec quarry) for Ordovician cystoids or Jurassic crinoids. If you need more detailed pictures, please send me a private message Regards, Kasia -
Arizona, Redwall limestone, Mooney member. I've found several examples of what look like plants but because they are around crinoids I'm thinking possibly crinoid arms. Anyone know what these are? Thanks

My beautiful wife scheduled a three night stay at a cabin in a Thousand Trails campground near Lake Texoma. We were to arrive on Sunday and check out on Wednesday. So, I figured that, since I hadn't been fossil hunting in months, I would schedule a trip to central Texas to follow the Texoma trip. I set up a rendezvous point in Fairfield, Texas to meet my dad on that Wednesday, and head off toward Brownwood and Cisco, Texas. I figured that the fossil hunt would begin then. But that's not quite how things played out... My two oldest daughters and I met my wife and youngest daughter in Salado, Texas on Saturday, October 14th. They had left the previous morning to spend a day with my mother-in-law in Waco and Salado. We spent Saturday night in Salado and then parted ways with my mother-in-law on Sunday morning and headed toward Lake Texoma. As we drove through Waco, my wife asked if we wanted to take a detour. She had never been to Dinosaur Valley State Park in Glen Rose, Texas, and she thought the girls would enjoy seeing the dinosaur tracks in the Paluxy River. I got really excited. I hadn't been there since I was a kid, and at that time, the river was high and the tracks were not visible. So we adjusted our GPS to take us to Glen Rose. We pulled in and stopped off to get a map of the park. We then drove straight to the spot where Roland T. Bird made his first discovery. It was amazing. The water was low and gave us a clear view of the trackways in the river. Above you can see both the sauropod and theropod tracks, They are a little obscured by mud, but they are still very visible. We left the R.T. Bird site and went to another place called the Ballroom Track Site, where so many tracks go in so many directions, it was like the theropods were dancing. It was in slightly deeper water, but it was still beautiful! The rippling water was crystal clear and the girls couldn't help but get into the water, even as a cool front brought chilly winds down the river valley. My wife loved it. She told me that Dinosaur Valley State Park was our next camping destination. Before we left, we stopped off by the iconic Tyrannosaurus Rex and Apatosaurus models built for the 1964-65 World's Fair in New York. They were permanently installed at Dinosaur Valley in 1970 at the park's dedication. We left Dinosaur Valley and drove the rest of the way to our cabin at Lake Texoma, arriving just after dark. We settled in and tried to decide what we wanted to do the next day. It was Monday, and we figured there had to be something for the girls to do nearby. We quickly discovered that our options were limited. It had turned too cold for the pool at the campgrounds. The putt-putt at the campground was okay, but the girls quickly tired of it. And most of the other recreational equipment was not well kept, or available. So, we decided to leave the campground to find something for the girls to do. I had mentioned that I would like to check out the Permian site at Waurika, Oklahoma. It was only two hours away, and this was the closest I had ever been to the site. My wife was a bit miffed by the lack of things for the girls to do, so she said "Let's go." I jumped at the chance. I had done no research on the site, other than what I had read about it on TFF. I wish I had consulted the TFF experts before we left, because I had no idea of the best places to look. We focused mainly on the sandy floor and reddish rocks, and found nothing. When we returned to the cabin, I asked where we should have looked. Jesuslover340 informed me that the gray colored exposures were the places to find the best material. So, we came away empty handed, with only one major discovery. My wife wouldn't let me take it home, though... Continued in next post...

This is probably a rookie question, so I ask for your indulgence. I have several thousand fossils collected over 50 years. I have a couple of hundred that I keep in plastic storage boxes in the house (crinoid stems and segments, bivalves, some horn coral and other corals, the one trilobite that I purchased that is probably a fake). But the rest are outside in a rock garden in the backyard. We're talking about a lot of fossils. The first question is: When you have so many fossils, what do you do with them all? And secondly, I have many fossils found in clay (see images). Will the elements have any negative effect on them? I live in Michigan, so we get lots of rain, snow and freezing temperatures.

Last week I drove out to Kentucky to spend a week with my family. Of course I also hit the fossil beds. The first day I visited the two Mississippian sites- Wax and Leitchfield that I visited last year. Here are some of the highlight finds of that day. First- Wax: Blastoids and bryozoans:

I have three fossils I collected last week in Kentucky during a family visit. The first I know is a partial crinoid head, missing most of the calyx, but what genus/species? It was found near Leitchfield, KY in the Leitchfield Limestone, the Jimmy Dean member. The second, I don't know what it is. It was found in a layer that was rich in crinoid stem pieces. The locality is just north of Elizabethtown , KY. I don't know the formation, but it is certainly Mississippian. The last object I'm not sure is even a fossil though the thing on the bottom is a crinoid stem piece. I don't know if it is attached to the object in question. It was found at the same locality as the second fossil. I would like to thank TFF member Herb for leading me to these two localities. I welcome and all input. Thank you.

When our Plan A was killed we had to go to Plan B. Plan A was to visit a couple of old mines and sample the mine dumps for pyrite crystals and to try my hand at gold panning some of the tailings a little. This couldn't happen as there was some sort of bike race going up and down the canyon the mines were at the top of. Not wanting to waste the drive over there, we decided to visit the nearby limestone outcrops and viola! Pentacrinus crinoids! More pics

Help planning large fossil trip in Pennsylvania
Fossil123 posted a topic in General Fossil Discussion
(Note: this was originally posted under fossil trips) Hey there! I'm sorry its been so long since I've posted on here but suffice it to say I need your help. I'm planning a six to seven day fossil hunting trip in Pennsylvania (sometime in mid august) and I need your help verifying that the sites I've picked to visit from Robert Beards guide Rock Hounding Pennsylvania are still accessible to collecting as well as coverable given my time frame. The places I'm looking at hunting are sites 27. Beltzville State Park (Outcrops on shoreline), 28. Lehighton, Lehigh Canal (Former borrow pit and outcrop),30. Deer Lake (Borrow Pit), 33. Suedberg (Outcrop in former borrow pit), 35. Centralia (Former strip mine outcrop), 38. Rockville (Former quarry), 48. Walker Lake (Hillside and unpaved road), 51. PPL Montour Preserve (Hillside, Former borrow pit), 57. Uniontown (Former quarry). Any insights as to whether or not theses sites are still accessible to collecting, weather our not you believe covering all these sites within 6 to 7 days is possible, and any other tips and tidbits of information on the sites, and or planning a large trip like this etc, would be greatly appreciated! When I go I'm planning to take notes and pictures and then, when i get back, write a few essays illustrated with pics that I will post on here! Thank you in advance, and thank you to Fossil-Hound for directing me on were to properly post this! Glenn aka Fossil123 -

Brechin, Ontario with Malcolm and the New York Paleontological Society
Jeffrey P posted a topic in Fossil Hunting Trips
The weekend of June 24th and 25th I participated in an outing with the New York Paleontological Society led by my friend, Ray McKinney to Brechin, Ontario. TFF Member Malcolm led our group into the James Dick quarry where both Bobycaygeon and Verulam Formations are exposed. These are Middle Ordovician from the Trenton Group and contain a wide variety of invertebrate fossil fauna. Also met other TFF members Kevin (Northern Sharks) and Joe (crinus). Most of the quarry is the Bobycaygeon and the very top is the Verulam- only accessible near the entrance, but I got some excellent well preserved matrix plates from there. I spent the second day combing the spoil piles. This first picture is Lake Simco by Beaverton where we stayed.

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.
