Paragassizocrinus tarri., North TX Mineral Wells Fm Feb, 2023 A stemless floating crinoid. -
I found the fossil attached a while ago in Tyrol, Austria. More preciselly, in the valley of Brandenberg in which many beautiful fossils can be found (mainly gastropods and ammonits). I am having a hard time to identify the fossil below and I am also not so experienced. Could i be a crown of a crinoid? The size of the fossil is around 8cm. Unfortunately, the stone is very porous and it almost falls apart.

I haven't posted in quite a while, so I thought I would post pics of some of my 2023 prep jobs. I have done a lot more than these but these are the only ones I took a before pic. Zacanthoides idahoensis Cambrian Spence Shale Richmond, Utah Pseudogygites latimarginatus Ordovician Lindsay Formation Bowmanville, Ontario, Canada Ceraurus plattinensis Ordovician Bobcaygeon Fm. Brechin, Ontario, Canada Archimedes wortheni Mississippian Warsaw Fm. Fenton, Missouri Platycrinites bozemanensis Missisippian Lodgepole Fm. Bozeman, Montana Aphelecrinus okawensis Mississippian Bangor Fm. Lacon, Alabama Glyptocystites multiporus Ordovician Bobcaygeon Fm. Brechin, Ontario, Canada Eldredgeops crassituberculata Devonian Silica Shale Paulding, Ohio This is one I really wish I had a before prep pic. The specimen underneath was a complete surprise.

Crows Feet? I’ve seen these in limestones but not in dolostones. Plenty of bits and pieces. I think Favosites and molds of crinoid columinals. More crinoid molds and both brachiopod molds and bits and pieces. Very very crystalized. But fun challenge.

A beautiful Dorycrinus crinoid calyx I found while out setting fish lines. This specimen will be very nice after preparation.-

This mold seems large to be from a Crinoid stem. It’s almost 1 cm in diameter. But I can see faint horizontal lines that the camera is not picking up. Any help or guidance appreciated.

What is the difference between crinoid and blastoid columnals. I know the difference between the calyx of a crinoid and the theca of a blastoid. I have a site I visit that has a mash up of both calyxes and thecas, but not with attached columnals. It is a Mississippian site, Warsaw formation.

An intriguing crinoid calyx from the Chouteau Formation of central Missouri, likely Aacocrinus boonensis . I'll clean and ID this specimen properly later this year.-

A recent fossil exploration trip in North MIssissippi resulted in a new Mississippi Fossils YouTube "How to" playlist. I believe I found a horn coral (top) and a crinoid stalk piece (bottom). A small quartz rock is also pictured in the middle. I also think I spotted an embedded oyster shell. darrell barnes

Today I went through some piles of weathering Fern Glen limestone I have outside, and I found the cutest little calyx. First thought was it was a chunk of stem, but after chipping it out of the rock that was definitely not the case. I compared it to some literature I had on hand, and believe it is small Agaricocrinus pracursor crinoid calyx. I Would like some second opinions. Unfortunately I don't have an air abbraider to clean this calyx further and it being so small as well as ironstained makes it tough to photograph well with my old phone, so I will add a couple more photos than usual. Thanks as always. -Jay

Hi TFF. I hope you can help me with this mystery. I found this unusual fossil at a rock shop in Northern California for only $15, so I figured I would grab it for that price and figure out what it is later. How hard could it be? I had the label and everything. Well, now it is home in New York and I think the label must have gotten switched because it looks like a mispelling of a trilobite. The fossil gives off crinoid or rhinocarid/phyllocarid vibes, but I just can't tell. Any ideas?

Found this in a cliff side in Colorado I am not sure but it looks like a mollusk or Crinoid bulb, DINOSAUR EGG!😆 Thanks!
