During a recent (Sept.16) fossil hunting adventure I was searching for the source of the concretions containing fossil ammonites to get a better understanding of the stratigraphy I was standing in. So I went to the top of the slope/cuesta to check out the current highest layer. It was tons of saltine cracker sized bits of shale/sandstone and slabs of the same protruding out of of the lip of the ledge. No fossils were visually evident so I pulled the nearest slab out and flipped it over. The slab was smooth on the top and when flipped had a loose coating of either white calcite or shaly bits li

I havn't been fossil hunting a very long time....I've only been really serious about if for the last 6 years. And in Central Texas, there ARE a lot of fossils, but it is hard to find a new spot that has not already come under the hunting radar of the many fossil hunters in this state! And some of them have been at it for a LONG time so they've usually found all the really good spots! Which is one of the reasons I love the Paleo Society of Austin, because I learned of some of these good spots from them....they are typically still productive, if not over hunted, so I love finding stuff there.

Recently found this rock on a trip to the Keasey formation near Mist Oregon. There are several crinoid stars visible on the outside of the stone and some segmented sections visible as well. Seems like they run throughout the rock. I found this on the ground by the stream and water erosion did a bit of work on the outside. Really curious and excited about what might be inside but no idea how to start and scared to ruin it. Any advice would be very much appreciated. Thanks.

Hi, I suppose Crinoid head on the first picture, and stem segments o the second one?

I collected this plate at an outcrop of Bailey limestone yesterday while looking for trilobites. The crinoid fauna present is limited with Scyphocrinus and Lecanocrinus reported. This slab had a visible larger crinoid dorsal cup exposed on top. The plates that are exposed on the cup match well with Lecanocrinus anna (formerly Alsopocrinus anna). I removed some larger portions of stem, and exposed some free arms branching off of what looks like another crinoid. Any opinion if this is a different crinoid, or possibly just a piece of Scyphocrinus? I know preparation would likley be needed for a c

Can you ID where a square crinoid columnal fits in it's morphology
Denis Arcand posted a topic in Fossil ID
The crinoid columnals i have found are usually round, pentagonal and star shaped, but today I found one that is square Among a thousand crinoids columnals, this is the only square one I have ever found, why? To which part of the crinoid does it belong to? -
From an old collection, no data, may be from USA or Europe. The conical calyx has a two-inch diameter, a recessed attachment for the stem, and five very broad attachment points for arms. the calyx has a hole through the center which is surrounded by concentric layers of shell so that, except for the central hole, it is solid (unlike any other crinoid I have seen or read about.) The ovoid specimen is probably from the same locality. It apparently also is almost solid, has five bowl shaped arm attachment points and an irregular central bowl. The base is recessed but covered in limestone. Th

Hi could this possibly be a fossilized leaf? Or is it just my imagination. Found it in a creekbed near the Mississippi in Northern Missouri. Thanks in advance!

Beltzville State Park - Middle Devonian (Mahantango Formation)
Masonk posted a topic in Fossil Hunting Trips
Family and I took a trip to Beltzville State Park earlier this week. We stayed around the lake, looking along the shoreline and wading through water. Found some pretty cool Middle Devonian fossils. My wife lucked out with two Trilobite pieces, one of which is a really nice head imprint. I'm still working on identification, so please bare with me. Any help of course is appreciated. Coin is 22mm Shoreline Trilobite head (Phacops rana?) surrounded by Crinoid stems Trilobite (Phacops rana?) - lower abdomen- 15 replies

I collected this echinoderm part from Silurian Bainbridge Formation outcrops. There are two spike-like projections exposed, and two more that are buried in sediment. The rock unfortunately split in 2 pieces, and I noticed two other spike-like projections on the opposite side while glueing it. I thought it looked somewhat similar to an Ancyrocrinus holdfast, but the age is wrong and I haven't found them reported from here. I apologize for the poor quality photos, I will update with better quality ones when I relocate the specimen. Any clue if this is a holdfast indeed, and if so what crinoid it

The first Macrostylocrinus crown from the Waldron Shale
Mochaccino posted a topic in Member Collections
Hello, I don't usually make separate posts to show off individual fossils, but I had to make an exception because this one is very special. It is a near-complete crown of a crinoid known as Macrostylocrinus striatus from the Silurian Waldron Shale of Shelby Co. Indiana, USA. I didn't really know what it was until I had it prepped and identified by experienced collectors. Though small (2 cm) and seemingly unassuming, this fossil is exceptional because as far as I know and am told, no crown of this species has ever been found from the Waldron Shale. Until now this crinoid- 9 replies

Age: Ordovician: Approx. 454-452 Mya Formation: Decorah Shale Location Grant County, Wi Amidst the frequent outcroppings of Platteville Limestone in Southern Wisconsin, you occasionally encounter the overlying Decorah Shale. From what I read this formation is more frequent north of Grant County, and in Minnesota as well. The outcrop itself is roughly 200 feet in length, and only extends about 6 feet from the ground. Its located in a very remote area, amongst a sea of corn fields. Here are a couple finds from my third trip to this locality. Here is a complete crinoid

Found these last summer but just getting the energy to find somewhere to ID them. I'm not sure what the crystallized impression is, but I know at the very least that the others are probably crinoids of some kind. Thank y'all, even if nobody can ID at least others can enjoy.

Hi I found this in a creek bed in Missouri not far from the Mississippi River. Need help identifying please. If I were to guess, it's some piece of a crinoid? It's my best find since I started this new hobby. Thanks

Hello! I’m new to the forum and come across fossils and interesting rocks regularly. I would love to learn more about my findings from anyone here that has a keen interest in helping someone like me expand my knowledge! These photos are of my most recent finding, but I don’t know what it is/ where it’s from/ when I dates back to.
