Can anyone recommend a good book or a good web site on current crinoid classification?

Hi everyone, its been a while since I posted here so wanted to share some of my favorite finds from the past few months. Ive mainly been hunting in the marine Blackhall Limestone at various sites across the Midland Valley of Scotland. Although there are several fossiliferous marine limestone and shale bands of similar age and depositional environment in the Midland Valley, the Blackhall seems to be by far the most productive and also tends to have the best preservation. Ive mainly been looking for chondrichthyan teeth, crinoid cups and jellyfish so I'll post these first, I have had a few nice

These Crinoids were found on a small cape, in Bali (GREECE).I know what species of Crinoids lived in that place, but I didn' found images of all those species to identify them. Species of Crinoids: Apographiocrinus nodosus Pindaxocrinus granulosus Moapacrinus sp. Protencrinus baliensis Synbathocrinus cretensis Artichthyocrinus koenigi Age; Asselian Can you help me identify them if it's posible? Thank you. 1,21 23

I just wanted to say thank you and Happy Holidays so to all of y'all. You've made my life a little bit richer all around. I hope the New Year brings us all many wonderful things...including new fossils! Sincerely, Jamie Lynn Crinoids are from Texas Cretaceous, Texas Pennsylvanian, New York Devonian and English Jurassic.

Its been a long time since I last posted any finds, so I thought I'd show you folks what Ive been finding so far. Ive been out a lot this year, and have done quite a bit of exploring. I haven't taken pics of everything yet but Ill add to this as I do. This past summer I took a trip to west Tennessee to an exposure of the Coffee Sands, a Late Cretaceous formation. I was able to find the site, but unfortunately, I found no fossils there. Luckily there was an exposure of the Lower Devonian Birdsong Shale nearby! This site exposes the 'brachiopod zone' which is the bottom of the format

Hi everyone. Interesting shapes on rock. Circular shapes both indented and extruding from rock. Found in Fairfield County CT. I'm pretty new to this and have no idea what this stuff is but interested to learn whether geologic or otherwise. Thank you.

Goodmorning/ afternoon all! Being a middle aged 20 year old, I've outgrown the need to go trick or treating for candy on Halloween. This year, my brother and I were supposed to have my nephew over for the weekend. We had originally planned some fun activities for the little guy (he's 4) as real trick or treating was out of the question this year. Turns out this week that 4 of his day care workers came down with the Covid, so he's now in quarantine at his mom's house for 3 (her choice, she won't budge) weeks. All alone for Saturday now, I decided to go out and look for the real treats, f

A Day in the Lower Devonian with the New York Paleontological Society
Jeffrey P posted a topic in Fossil Hunting Trips
Yesterday, Tim (Fossildude19) and myself met at our usual meeting spot and with Tim driving and his downloads playing, we headed north to a planned rendezvous with the New York Paleontological Society's outing at Cobleskill Stone Products just outside Schoharie, N.Y. The weather was gorgeous- perfect really, sunny mid-50s. Fall colors were in full swing. We drove through the northern edge of the Catskills, arriving early at our rendezvous, the parking lot at the Cobleskill Stone Company. It was my first time there since 2013. I went on two previous NY Paleontological Society outings to this si- 28 replies

Hi everyone! Today, a friend of mine from the Paleontology course at the University of Bristol and I went fossil hunting at the beach of Portishead, as we had heard it was an interesting and productive location. We were fairly confident that we would come home with at least some crinoid pieces, as these were meant to be rather abundant, but our real goal was to hopefully find some of the elusive eurypterid remains. It was about half an hour bus ride from the center of Bristol to Portishead, so it's relatively quick and easy for us to get there. It didn't take too long fo

Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State R

Planning a serious Iowa excursion for my Uni before winter hits. Was curious if any of you have done any rockhounding around the Le Grand area. Apparently is a site for exquisite crinoid plates. Just curious before I start calling the stone company and procure access/permits/etc. https://www.legrand.lib.ia.us/Library-information/fossils/crinoidfossils was sent a link to this by a contact at UNL...hence my sudden interest https://www.iihr.uiowa.edu/igs/publications/uploads/Em-04.pdf

I'm just easing back to regular life after a week of fossil collecting in the province of Quebec. We had a fantastic and highly productive time. There are a number of sites that I cannot mention publicly, and also some excellent specimens that I am sworn not to post anywhere, but I can show a few things. I haven't photographed everything yet, either. We collected mostly in the Neuville and Nicolet Formations. The first stop was Kingston, Ontario where we met up with a fellow fossil friend for a brief time. I obtained my own physical copy of Isotalo's book. I then meandered to a roc

Why are crinoids usually the only type of fossil in an area?
Digi posted a topic in Questions & Answers
As the title states, why do crinoids often show up alone as the sole type of fossil in an area? There's a quarry near my house I've been to a few times that has crinoid bearing marble. I've found a few crinoid stem pieces in rocks, but I don't really understand why they're the only type of fossil (unless you count chert.) The area is Permian-Devonian, so if crinoids fossilized shouldn't plenty of other common marine animals have fossilized too? Or am I thinking too narrowly and there's a good chance they DID fossilize and I simply have to look a little deeper? I'm not too knowledgable on the p -

I found this while searching for geodes and crinoids in a southern Indiana lake.

I recently acquired a small collection; and most specimens were well described....except for a few specimens that at least had age, locality etc .......the attached specimen containing two crinoids and calyx had VERY little information at all. I believe it may be from Illinois, as this was the only information supplied with the specimen. Any help with identification would be greatly appreciated.

I found all the crinoids below at Lake Michigan beaches in Illinois. (Silurian, Racine formation) I have to admit, I used to not pay too much attention to the ubiquitous crinoids on my hash rocks. That is, until I started to look at them with a clip-onto-the-phone microscope. I quickly found that crinoid disks aren't all the same and are actually quite beautiful and intriguing. Also, finding a pretty little crinoid calyx at the beach got me to look for more like it and low and behold, a short time later, I did find another one. I do believe they are very rarely found at Lake Michig
