So I am driving on RT. 47 which leads to Vernonia and Mist, Oregon and a road cut that looks very similar to the Keasey locations I have been picking talus and for the first time it appears dry (seems to be a seep at the the top). In Oregon unless on private or in special circumstances BLM land you can not dig, you have to surface troll. I found a safe parking space and then crossed the road to enter the ditch. Once again close to traffic but people on this somewhat used road either slowed or pulled over, except for the truck who stopped and gave me directions to "a secret" place:), now that's cool. I had stopped here during winter but it was really wet and I left after finding a mollusc taking an image so I had the GPS. This day it was very different quite a few concretions had fallen out of the formation. These are very, very had carbonate concretions. So I decided to pickup 3 or 4 and see what I could find. There are lots of sociological items on this piece. However the object of interest in the focus of these images. I have an assumption (I'll post mine after a day or two) of what this is due to the formation (if I am right and the location of this outcrop in relationship to Vernonia and Mist, Oregon). That being said what is your best guess?

Total fossil newbie here. A few weeks ago while running, I randomly noticed a weird rock that I thought might be a fossil, and some nice folks here helped me ID it as crinoidal sandstone with a few brachiopod impressions. I figured it was a one-time thing, but when I ran the same route today, I could help but keep an eye out and was shocked to find , now that my brain is primed to see them, that the ground in that area is just littered with crinoids and brachiopods. I've been running right over them on almost a weekly basis for a couple of decades without ever noticing. I know these are probably boring fossils for most of you, but I still find them fascinating. I have a couple of questions about a few details on these that I hope someone will answer. Here's a few general photos of them. I know the one is crinoid pieces. I think the other is a brachiopod - is this correct? And the few details: is this part just a side view of a crinoid stalk, or is it something else? And this - another part of a crinoid? Or something else? And finally, from the one I think is a brachiopod, it looks like there might be an impression of something else just above it (closup below). Is this something? Or just a feature of the rock? Thanks for any help!

I think the first post I made here was about Partridge Point. I'm still not a fossil expert, but I thought this video I made might be useful for someone thinking about visiting this spot. It gives a good idea of the types of fossils that you can find. Maybe someone can help me identify a couple things I wasn't sure about.

This specimen is from the Ordovician Platteville Formation of Wisconsin. The top part looks like a crinoid stem, but the larger disc at the bottom is throwing me off. My only thought was possibly a holdfast. Any thoughts?

This is an enlargment of a photograph I took a while back, where only later did I spot the odd fossil. Apologies for the low quality. I'm curious about the star-shaped object with seven corners. This is from the Madera Group in the Jemez Mountains of New Mexico, which is a Pennsylvanian carbonate shelf formation with abundant crinoids, brachiopods, and bryozoans. I've heard of star-shaped crinoid stem segments with five points, but not seven before. Any ideas?

Texas Pennsylvanian Weekend - Trilo, Crinoids, Goniatites and More!
JamieLynn posted a topic in Fossil Hunting Trips
The Paleontolocigal Society of Austin monthly field trip was last weekend - we planned to hit a couple of spots in Brownwood. Well it's a bit of a drive from San Marcos, so I decided to make a mini two day trip out of it and stay in an Air BNB (a great option for traveling these days - no shared air source like a hotel!) . So instead of just the two sites on Saturday with the Society, I headed up to Lake Jacksboro for some solo hunting! And boy was it solo.....not a SINGLE person at the site! I was astounded. Had the whole place to myself for HOURS! It was a beautiful day - 70s and sunny. I can't believe no one was there! I was really hoping to find a whole Goniatite (had found one small fragment in the past) and thought I had hit the jackpot when I saw that arced edge sticking out of the dirt - praying to whatever omnipresence was available that it please please be a whole one! Alas....it was not. But still a better piece than I had! Found a couple of other nice goniatite fragments too. Goniatite Gonioloboceras sp. 2 inches Goniatite Pennoceras sp. (I think - if anyone has a better ID, lemme know) 1 inch I was super excited to find a couple of Conularias too (I'd not found them before) 1/2 inch Also found this odd Cephalopod Poterioceras sp ( I think) 1 1/2 inches Then I found this weird thing - I think it is an odd brachiopod called Collemataria nobilis 1/2 inch And lastly I finally found a nice (honking big) Derbyia crassa bivalve 3 inches So after a really nice time at Jacksboro, I headed back south to hit Mineral Wells fossil park - a great little public fossil hunting spot. I pulled up and there must have been 25 cars in the parking lot! SPRING BREAK! Each car had a family of at least 4 (mostly little kids) out digging in the dirt. Fortunately, it's a big place, so you could avoid everyone, but so many people had been out there digging instead of surface collecting, that is was pretty much a waste of time. I found a few nice little things, but left pretty quickly. A nice Crinoid cup fragment 1/2 inch a tiny bit of echinoid spine 1/4 inch and a nice sized Gastropod Goniasma lasallensis 1 inch My last stop of the day was a roadcut I had found last time up in that area - unfortunately, there was a very large, very dead hog t the site and it was, of course, upwind. So I didn't stay long because that's just unpleasant. Did find a couple of nice things there, though! What I think might be a Stenopoceras nautiloid 1 inch and a whole mess of really gorgeously preserved echinoid plates - Archeocidarid I think I stayed in a little Cottage (Air BnB) in Dublin Texas - and yes, they have outdone themselves with the Irish theme in the town (plus it was just 2 days after St. Patricks Day so there may have been a little "extra irish" going on). Nice little town. Got up early and met the Society for our fieldtrip. We started out going to the Brownwood Spillway - a dramatic landscape for sure! Huge overhangs of heavy limestone (stay away from those overhangs, y'all). The fossiking was sparse, but the finds were amazing....those who found stuff. I came away with a really nice 6 inch hashplate full of bryozoans and crinoid bits. Then, we headed out to the second site where I KNEW the fossiling would be good! And boy was it....first I found my first trilobite from this spot (just the trilobutt, but hey, I'm not picky) Ditomopyge sp. 1/2 inch and then, my next best find (or first best, depending on your preferences!) I found the arm fragment first, uphill, and then the base downhill!! An "almost' crinoid crown! Delocrinus sp 2 1/4 inches My last and final adventure of the day (I decided I'd had quite enough fun and was ready to go home after this....) My First Rattlesnake Encounter! Yep, was poking around some big rocks up a hillside looking for shark teeth when I heard that distinctive rattle......I think I actually flew down the hillside (I know I leapt over a couple of cactus and some really large rocks on my way down). So that was enough fun for one weekend! (See the snake? He's under that big rock....hahhaha!! The one halfway up the hillside.....)- 24 replies

The club went to the Brownwood Spillway and Wilson Clay Pit Saturday. Weather was spectacular! I decided to skip the spillway and head straight to the old clay pit. Had the place virtually to myself for the first two hours. I headed for a spot that has always panned out with good crinoid material and some nice teeth. I had joked around with the other members that I needed to go there and find the complete crinoid calyx and arms I saw in a dream. Well I found it. But you know how things are always bigger in dreams...

can anyone tell me what all these fossils are in this rock ?
matthew textor posted a topic in Fossil ID
Hi everyone this is Matt again I have a rock I found with a lot fossils in it but I have no clue what they are ? I found it in the creek next to 28th creek rd. in kennedy N.Y. can anyone tell me what the fossils are ? here is a photo -
My wife found this in some talus. It is 5mm long axis. Image was taken with a G9/Oly 60mm with extension tubes (2x). Is this a Crinoid? Looks like the feeding part. Any Ideas on what this fossils is? Keasey Formation, late Eocene. Mostly Mollusk and Gastropods however Crinoids are listed as being found in this location but rare.

I did my first microfossil sifting on the sandbars of the Kaw river in Kansas (I posted the trip on the forum ). Anywho, I found this microfossil that reminds me of modern day cowrie in pattern but I'm guessing its a coral? The second I am pretty sure is coral, the third is a worn crinoid segment? and the fourth, ummm I don't have a clue- one side has three parallel ridges- thoughts? Appreciate all the help as always!

I had some spare time this past weekend, and a fossil hunt sounded nice. Bad weather had made that impossible the previous month. The weather was great out finally, so I went out Sunday (3/7/2021) to good old Truman Lake to look for Burlington Formation crinoids. I mainly just wanted to find and keep nicer, intact crinoids that day. It's a good walk to the crinoid hunting grounds from my car, and there is fossiliferous chert material along the way. I decided to split one chunk of chert, which contained only one single platyceras gastropod steinkern. After finishing work on it, I hid the snail along the trail behind a tree because it was to delicate to carry along. I actually ended up forgetting it, and will have to retrieve it next weekend. Once I got done walking and hit the encrinite rock, I decided to hunker down and look for recently fallen debris. Within 5 minutes I found my nice first possible complete calyx. Only prep would tell if this was complete, but it was worth throwing in the backpack. Looking low was paying off, because 3 feet away and right where the water level dropped was another one. I could tell right off the bat it was an Azygocrinus rotundus. It looked complete, but being lodged upright and inbetween two more pieces of rock, it was almost guaranteed to either be missing plates or extremely weathered. It was weathered, but actually better than I had thought! As I kept going, I kept flipping rock. Its always good to look at the underside of fossiliferous rock, because I've found some nice pieces that way. The next find was found doing just that, and looked to be a complete Macrocrinus verneuilianus. This is what I saw before flipping it over. And the backside after some rinsing in the lake. After throwing that in the backpack, I kept scrounging. Macrocrinus was the most common find of the day, and I found another within minutes. This one was buried in some sediment on a bigger chunk of rock. Can you find it? It will definitely clean up well. I spent another hour or so looking around and also managed to find a nice Uperocrinus pyriformis crinoid and another partial Macrocrinus verneuilianus calyx, but I didn't get pictures of those in the field. I cleaned up everything with soap and water when I got home, but I only had time to prep one crinoid and partially prep another one. Well, heres the calyxs cleaned up. Uperocrinus pyriformis Macrocrinus verneuilianus #1 (first crinoid find after final prep) macrocrinus verneuilianus #2 Macrocrinus verneuilianus #3 Azygocrinus rotundus Macrocrinus verneuilianus #4 And why not end on a brachiopod! Thanks for reading.

From the album: Platteville to Decorah formation Ordovician Twin Cities
Larger picture of the same trilobite. Just to show an example of upper Decorah twin cities hash plates. Certain crinoid species are very strongly represent compare to middle and lower Decorah Formation. The largest crinoid species is often in single pieces or sizable stem pieces but head and suction portion are unusually absent. In Middle and Lower Decorah formation, the density of crinoid fossils tend to be lower. -
Brachiopods orthoceras crinoids all found right here in Hendersonville TN Sumner county just north of Nashville. Love to fossil hunt and see what I can find while imagining worlds of the past.

I needed to get out of the house for a few hours and so went to try my luck at finding some local Silurian fossils. First outing of the year. My first best find was this crinoid which I believe is a Eucalyptocrinites crassus calyx. A good size. On the reverse side is a small Encrinurus egani. This next find I was pretty excited about. A large D. platycaudus cephalon. I took it home to prep... Unfortunately, the preservation was not ideal, but that's the way the cookie crumbles. I placed a nicer example next to it that I found last year for comparison. 7cm across. Thanks for looking.

Work and weather have kept me from doing much fossil collecting these last couple of months. But I was finally able to photograph finds from my last outing. I found some interesting stuff I think. We'll start with my favorite find.. This is the large blastoid Xyeleblastus magnificus. They're always found crushed to some extent (even the holotype.) This is only the second blastoid I've found in the Fort Payne! Did well with the crinoids that day A very nice Agaricocrinus sp. with the stem attachment point exposed (they usually have that area filled with matrix.) Also shows an unusual texture that I havent seen on other specimen in my collection. Another Agaricocrinus sp. calyx slightly damaged and with calcite coming out from between the plates. Agaricocrinus is one of the three most common genus from that formation. Another being..... Alloprosallocrinus conicus. I never find one with the anal tube intact, most likely from them being transported and deposited. Heres a slightly rarer one... Gaulocrinus veryi I normally don't collect stem sections anymore, but I did decide to grab this large section.... Its a Platycrinites sp. stem. They are distinctively twisted. This is my second favorite find of that trip.. Its and Auloporid coral (most likely Cladochonus sp.) wrapped around a crinoid stem section! More later...

From what I've learned crinoids aren't from around here, prob from way upstream fill rock. Here being Dallas creekbed in Eagle Ford shale. Its so unique with the patterns, almost looks carved, just guessing part of a crinoid because of the cylinder shape. What the heck is it?

Invert fossils from Devonian of Bundenbach
Shelley newbie collector posted a topic in Is It Real? How to Recognize Fossil Fabrications
Any feedback on the authenticity and quality of these 2 fossils? I'm assuming the quality of the brittle star is not top notch, as the seller didnt provide close up photos but fir the right price, I might still buy it if it is authentic. Any advice will be much appreciated as I learned a lot from my recent post of a similar nature!- 10 replies

Hello this is my first visit here, and no I didn't go on airport property but was on the border at a small tributary. I have found a lot of crinoid stems on the past and this looked similar, my best guess was part of crown. Am I close? I included couple pics of bivalves and an ammonite found in same place if that helps.

Hello, I believe this to be a "holdfast" from the Crawfordsville Indiana crinoid locality. I am hoping that someone could help with identification of the particular species, and also if there is a scientific name for "holdfast." Thank you!
