Found in Crane Hill, AL (Carboniferous) Could the (presumed) burrows be part of an Asterosoma sp? Thanks for looking

Hi! Looking for help with IDs & also What is this type of fossil called (counter-impression? cast?). Specimen from Crane Hill, Alabama. Thanks for looking Pics 1-plate overview- several potential invertebrates? 2- Potential invertebrate? Some of my newbie guesses: Trilobite (side view) Eurypterid- can’t find definitive info about if locale only had the giant type Crinoid (eg saggital view) Bryzoan Gooseneck barnacle- not sure when these appeared 3- same critter, different angle 4-other invertebrates? 5-stellate shaped imprint? 6-another area of plate showing black ‘spots’ 7-black ‘spots’ look angular, maybe cubic) on high power. No idea if or how this helps, but I wanted to see if it was mold (seems less likely). Included pic for fun (apologies for the quality).

Found last week in small stream in my yard south of Bham, AL which contains mainly early/mid Paleozoic era and potentially some late. This specimen resembles a crab fossil specimen from AL, but the time period doesn’t match up. Encyclopedia of AL Thus, what could it be? IMO, does not resemble the pics I find for Eurypterus pinchers. Another possibility is that it could have been mixed in with landscape river rocks rocks uphill from the stream?

I saw this chunk on a sales table at the recent Rendezvous of BC rockhound clubs here on the Island. Had to have it, though I keep telling myself to avoid fossils with no provenance. Anyone recognize it or have any hunches as to ID and especially location of origin? I guess somewhere on the eastern half of the continent... It appears to be a mix of cherty and crystallized composition. Whoever owned it before didn't treat it very kindly (lapidary types)... Apparently there once was a label of some sort glued to the top, and the rough saw cut which I hope to flatten better and polish someday.

Found this Paleozoic echinoderm. I’ve found thousands of crinoid bits but nothing like this.

Found in yard after heavy rain storm. The last photo is prior to cleaning off thick clay -like coating. I may have overdone it. Thanks for looking:)

Did I find my first cephalopod(s)? Last one could be a crinoid

Went to the local gravel pit. Walked away with this gorgeous gastropod and a beautiful bryozoan in jasper. Will be returning

Found this fossil in an agate of unknown age from a gravel pit ...
SilurianSalamander posted a topic in Fossil ID
I think it looks shockingly similar to charnia. Maybe a cephalopod, snail, or plant? What could it be?

Burrow? Coral? Bryozoan?
-
Can anyone identify this Paleozoic marine invertebrate fossil in my collection? I know some of you might say the whole rock is a piece of fossilized coral but I don't think the entire rock is a fossil. I believe the pores might be invertebrate burrows but I'm not certain. I purchased it at a fossil convention so the context is lost.

What is the stratigraphic and paleogeographic range of Whitfieldoceras?
siteseer posted a topic in Questions & Answers
One of my friends has a Whitfieldoceras specimen from the Ordovician of Wisconsin. He asked me if I knew anything more about it. I didn't and didn't see much online. Does it have a record outside the Ordovician? Is it found elsewhere in the U.S./the world? I have the same question about Beloitoceras. He has one of those from the same site. I think I have one from a Minnesota site somewhere but couldn't find it. Is it known from elsewhere and did it survive beyond the Ordovician? Thanks, Jess -
Can someone please identify this fossil for me? I found it in Broome County, New York and I believe it to date from the Paleozoic era as I found it in association with bivalve fossils which means the fossil in question is likely a marine species and New York was underwater during the Paleozoic.

Birthday Fossil Hunting trip to Ardennes (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last weekend I took a couple of days off work for my birthday and I decided to visit a fossil spot in the ardennes which was recently recommended to me because there was a chance to find fossils of primitive plants as well as devonian fish (which is one of my main interests within the hobby). The site is relatively close by as well which was a huge plus as it only took an hour to drive. The fossils in this location date back to the late Devonian, Famennian to be exact (372.2 million years ago to 358.9 million years ago) After searching for a 45 minutes we finally found the top spot with the right layer rich in plant material, here are some in situ pictures of the larger examples (which we didn't extract). If I am correct I believe these are the remains of Rhacophyton condrusorum which is a primitive species of fern if I remember reading once. We were also lucky to find some fossils of devonian fish, which was the main reason for our visit. A lovely small Lungfish (Dipnoi indet) tooth An imprint of a fish scale of bone While it was quite a cold day, it was sunny and we had a quiet afternoon at the spot where we could search in peace.

Hi guys! I was in the Warsaw Geological Museum and there I came across this specimen which reminded me of Tabulate coral, but it was signed as a "sponge"... The sponge from the "maastrichtian age", when Tabulata already was extinct. I couldn't be more confused. This one still looks like coral to me. What do you think?

I'm working with Dr David Campbell on possible fossils found associated with the Murphy Marble Fm in Western North Carolina. In 1973. Don Hathaway was logging cores at the Nantahala Limestone Quarry when he found what looked to be organic remains in a couple of cores cut into the Murphy Marble Fm. The age of the Murphy Marble is enigmatic, because of the lack of fossils in it, and it doesn't have the minerals that could be used to determine radiometric ages. The metamorphic grade of the marble and associated formations are garnet to staurolite grade. It's believed that these units were metamorposed during the middle or late Paleozoic. Unfortunately we couldn't handle the cores, and we were only allowed to photograph them. Since neither of us hasn't done research on brachipods before we are looking for opinions on the of these apparent organic remains. I almost forgot to mention that these fossils were apparently in an unit above the Murphy Marble Fm in the base of the overlying Mineral Bluff Group. I didn't take the photos so I don't have a scale for them. I finally did dig up a old picture from a talk given back in 2019 at a NCFC meeting in Raleigh and got a screenshot of part of the article to give you an idea of the scale on these pics.

Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missouri: • Smithville Formation • Powell Formation • Cotter Formation • Jefferson City Formation Enjoy and share as you like. Full citation: J. S. Cullison, 1944: "The Stratigraphy Of Some Lower Ordovician Formations Of The Ozark Uplift."

Illusory erect spines(?) on a Kimmswick receptaculitid
pefty posted a topic in General Fossil Discussion
UPDATE: These seem to just be weirdly incomplete cross-sections through ordinary cylindrical meroms. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This weekend in the Kimmswick Limestone in eastern Missouri (Pike County) I saw plenty of receptaculitid algae, mostly of genus Fisherites. But one cross-section has a feature I've never seen before: a fringe of what look like erect spines on the external surface. Can someone point me to a reference for understanding this feature functionally and/or taxonomically? I've looked in the usual places but I don't seem to be finding anything about spines. (If I were a vertebrate paleontologist, I would be saying they were feathers and proclaiming receptaculitids' "Sinosauropteryx moment.") Thanks.

While doing security rounds at work, I stumbled across a nice slab chocked full of brachiopods, tucked in dock-side rip-rap from Northern Michigan. It's pretty dark outside, so the pictures aren't the best, but I do see several types in it. Better pictures will follow once I get it home.

Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not just western PA but West Virginia and eastern Ohio as well.

I took my wife out for a quiet weekend in San Saba, TX and vicinity to escape from work and busy city life. It was fun to visit the river, suspension bridges, and bump into a couple old Indian campsites denoted by snails, freshwater bivalves, and burned rock on the surface. But the first thing to really catch my eye there was the small fossil display in the historical museum at Mill Pond Park...one fossil in particular. This huge orthocone nautiloid was the highlight of the visit for me. It is said to be from western San Saba County, which has Ordovician through Pennsylvanian strata. There was no provenance, so I won’t get too far keying this one out. I’ll have to just appreciate it at face value for aesthetic appeal, and for it being the biggest orthocone I’ve ever seen from Texas.
