Friends, this time I seek the help of a connoisseur of fossil corals, they are from the Neocomiano (Lower Cretaceous), from a town near Tehuacán, in the State of Puebla (Mexico). The scale is in centimeters. I appreciate your help because although I have dedicated myself to reading the scientific literature of the area, I am an amateur, and many of them are very similar. Of those who have an idea, I put their name for them to say. regards

Some Fossil Hunting in the Plabutsch-Formation of the Palaeozoic of Graz, Styria, Austria (Devonian – Eifelian)
FranzBernhard posted a topic in Fossil Hunting Trips
As there are some polished fossil-rock specimens from this formation in the Christmas auction, I would like to present some background info with (mostly) some field photographs, so I have put this in “Fossil Hunting Trips”. The Palaeozoic of Graz is a thrust sheet within the Eastern Alps, composed of Silurian to Pennsylvanian sediments. It consists of three separate nappes, the most fossiliferous formation is the Plabutsch-formation within the Rannach nappe. This Devonian formation is of Eifelian age (ca. 395 Ma), about 100 m thick and mostly made up of a very dark, gray-blueish to black, fine-grained, thickly bedded limestone. Superficially, it weathers to a medium to light grey color. Geological map of Styria with the Palaeozoic of Graz situated north of Graz. Stratigraphic column of the Rannach nappe of the Palaeozoic of Graz, Plabutsch-formation is Nr. 4. From Hubmann & Gross, 2015. Thicknesses of formations are not to scale! The Plabutsch-formation crops out at various places to the west and north of Graz and more than 100 fossil sites are known within this formation. The most abundant fossils are corals, brachiopods, stromatoporids and crinoid fragments. Other fossils like gastropods, bivalves or trilo-bits are very rare. In a paper from 1975, about 50 coral species are listed, but less than 10 are abundant: Tabulata: Favosites styriacus Penecke, 1894 Pachycanalicula barrandei (Penecke, 1887) Thamnopora boloniensis (Gosselet, 1877) Thamnopora reticulata (Blainville, 1830) Striatiopora? suessi Penecke, 1894 Rugosa: Thamnophyllum stachei Penecke, 1894 Zelophyllia cornuvaccinum (Penecke, 1894) Do you feel that there is something strange with this list? Yes, it is! Most species have their type locality within this formation and were first described by Penecke, except T. boloniensis (T. reticulata was also erected by Penecke as Pachypora orthostachys and later synonymized with an earlier described species). In my opinion, this does not reflect a high degree of endemism, but an urgent need for revision… The most abundant fossil is Favosites styriacus, which can form massive colonies up to 0.5 m in size. Here is an example from Hohe Rannach Mt. (1018 m) north of Graz, photo 05/26/2018, Col-Nr. 4093, length of pocket knife is 9 cm: As most fossils in this formation, it was found in scree and float in a wooded area. Nr. 4093 is waiting near the pocket knife toward the lower right corner… Another Favosites styriacus, north of Fürstenstand Mt. (754 m), northwest of Graz, photo 10/30/2015, not in collection. Tabulae are very well visible, weathering is usually your friend there!

I just got two big slabs of seabed from Kentucky from a friend of mine. As soon as I got home I took my hammer and chisels to them, and I found a lot of stuff in them. They are both 12 inches wide, and the smaller one is 12 inches long while the larger one is 18 inches long. I found a lot of interesting things, and I'm not done yet. It's going to be an ongoing project because the slabs are thick and one of them has a shell sticking out if it that I will have to work around, it is rooted to deep to get it out without breaking it. But it has been a lot of fun, and found a lot of cool stuff, including this weird stringy stuff that I have never seen before. It might be the burrows of marine worms, but I'm not sure. I also found what I think are fish vertebrae, but I haven't had a chance to photograph those yet, I will probably put those in a separate post later. If you have any idea what these three are please tell me, I am working on labels for all my specimens but without a plausible ID I can't do these yet. This is far from all I have found, I have found sponges, corals, shells, and what sort of looks like a crinoid stem, but I'm not sure because it is standing vertically in the slab, making it really hard to remove. I sent a small piece of the weird stringy stuff (fig. 2) to a friend of a friend who is a geologist, so hopefully that will provide some answers. I would rather have a paleontologist look at it but I will take what I can get, I'm lucky too have access to an expert at all so I shouldn't complain. Anyway, thanks for reading this, even if you can't identify any of these.

Dear TFF members, I need help with confirming the age of fossils I have found during the trip to the chalk mine in Mielnik. These specimens were found in the slopes and on the road leading to the mine, so a few tens of metres above the chalk deposits. I have read about the Ordovician deposits streching from Białowieża to Mielnik, so maybe they indeed come from this time? The specimens comprise corals, crinoids and brachiopods. I will appreciate your comments/ suggestions.

Has anyone visited Mazourka Canyon Road East of Independence? YouTube videos in the last year show a reasonable road and Donald Kenney [http://donaldkenney.x10.mx/SITES/CAMAZOURKA/CAMAZOURKA.HTM] lists a number of sites and the possible fossils. BFLADY

Aulocystis dichotoma (branching tabulate coral) Middle Devonian Moscow Formation Windom Shale Hamilton Group Deep Springs Road Quarry Lebanon, N.Y. This tiny tabulate coral- approx. 2 inches wide, was on a large slab which Shamalama Dave carried for me to my parked car. Unfortunately split when I was trying to cut down the size of the slab, but should be mostly repairable. -
Last week I drove out to Kentucky to spend a week with my family. Of course I also hit the fossil beds. The first day I visited the two Mississippian sites- Wax and Leitchfield that I visited last year. Here are some of the highlight finds of that day. First- Wax: Blastoids and bryozoans:

Again with the lips stuck to the mud. It is a good position to meditate while collecting small corals. I remembered @Kim Texan and @Coco, they liked these little Astrocoenia numisma. The gastropod I think it's Solarium. If not, someone will correct me, for sure. We always bring a little friend of the corals at home. Nobody is perfect. I also remembered @HansTheLoser. GAB2, Hans, you know. By the way, Hans, summer is coming. Do not forget something you owe me. Greetings to all.

Hi, Last weekend, in the limestone rudist-coral reef I'm working on I found this beautiful piece (not fully prepared yet). Upper-Cretaceous (Maastrichtean) strata. I'm aware that corals ID is very difficult, so I shall be well content if family or genus ID is possible. Thanks,

Hello, all! So I am cleaning out my workshop to make room for a lot of new material coming in and to prepare for the upcoming season. I have wayyyyyy too much Penn Dixie material. I have, at this point, committed all of my complete bugs away. But I still have quite literally, TONS, of other material. What I am offering is Edlredgeops rana partials, this includes entire prepped bugs that are missing cephalons, stand alone cephalons, pygidiums, large but broken cephalons, half bugs, etc. (Please note, I am not offering any of these as complete. There is the real chance that some of the unprepped material COULD be complete, but I am not offering them as such. I also have Greenops pygidiums and partials, beat up examples with broken cephalons, etc. I also have a few Bellacartwrightia pygidiums laying around, and perhaps a few broken and partials of them as well. I also have massive quantities of hash plates from the Bay View coral layer, brachipods (Mucrospirifer, Pseudoatrypa, Rhipidomella, Spinatrypa), Spyroceras cephalopod partials, rugose and tablulate corals, clams, and other random bits. I am interested in trading for similar material from other locales. I am not expecting anyone to offer up prime specimens for any of this material, but I would love anyone else's throw-aways that include vertebrate material, plants, small fish, and the like. I am also considering minerals and gems. (Again, throw-aways are all I'm looking for, quantity beats quality on this one.) I will cover shipping domestically in the US, but can't really afford to ship out a ton of international packages this month. (I will still do international, we just might have to work something out.) If anyone is interested, please message me! I want this stuff gone as quickly as possible, it's getting to the point where I can't walk in my workshop anymore! If you let me know what you're interested in I will take photos of some examples, but it would take me a full weekend at least to photograph everything that I have available. This is perfect for anyone wanting to practice prepping as the Windom shale that most of these bits are in is relatively easy to work and there are lots of attractive pieces that will look very nice prepped, just aren't worth the time and effort for me at this point. Cheers!

Most come from Illinois, and are as I figure corals and spines; question is what kind, and which? I apologize in advance, but instead of posting 20 threads for each one, I’m going to spam this one with all my sponge, coral, etc inquiries. So please be patient! (Thanks again guys for all your help! I only post the ones I cannot 100% identify via books and internet; unfortunately I gotta snarge ton more yet to come.) Here are items #1-3...

Lack of snow cover and warmer than average temps allowed me to explore and collect sponges and corals from the Pennsylvanian Naco Formation in central Arizona, north of Payson. Widespread chert of the Beta Member suggests that silicious sponges may have been common. Several have been identified but many more exist. I have seen and collected several undescribed species. Dilliard and Rigby have described several sponges including Chaunactis olsoni which I found in the area: The New Demosponges, Chaunactis olsoni and. Haplistion nacoense, and Associated Sponges from the.

Hello, I want to put together some pics of some of the reef material that I have found in Streetsville, Mississauga, Ontario on the banks of the Credit River. It is now winter and I am missing the warm days in which I can go and wade in the warm waters of the river for fun. I just want to compile and share some specimens that whose photos I have not shared with. All the fossils belong to the Georgian Bay formation, Upper Member, which is late Ordovician in age. First is the common coral that displays an enormity of growth forms, Favistella alveolata (Goldfuss, 1826).
