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.

Western PA Specimen Collection - Fossils of Parks Township
cngodles posted a topic in Member Collections
Hopefully I'm not breaking any rules here posting a link. I spent my weekend finally putting my catalog into a proper database, and creating a user interface for it. I used to use Google Sheets, which is pretty great. If I wanted to, I could use them as the source of data, but I decided to create a proper MYSQL database so I can keep relationships across tables, such as the stratigraphy of particular find locations. I have many more improvements coming for it, but it is at least functional right now. Everything from CG-0001 to CG-0161 is from the Glenshaw Formation, Conemaugh Group- 4 replies

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.

While at a local Barnes & Noble the other day, I saw a book I had heard about last year (published in September). It's "Beasts before Us: The Untold Story of Mammal Origins and Evolution (Bloomsbury Sigma, 2021). I leafed through it and it looks like a good read if you're into the evolution of terrestrial land vertebrates and specifically, synapsids.

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 metamor

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 mi- 6 replies

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?

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 Missour-

COMPLETED, THANKS!: Request for a missing plate from a classic trilobite paper
pefty posted a topic in Documents
Hi, I'm looking for help locating a plate that seems to be inexplicably missing from the online version of a classic trilobite paper. The plate I'm seeking is PLATE XXVI (26) from Lehi Hintze's 1952 paper Lower Ordovician trilobites from western Utah and eastern Nevada. Utah Geological and Mineralogical Survey Bulletin 48: 249 p. The only online version I've found, which seems to be missing plate XXVI, is here: https://ugspub.nr.utah.gov/publications/bulletins/b-48.pdf If anyone has access to a paper copy and can post a scan of PLATE XXVI (26) here -
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.

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 d -

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 st

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 j
