I found these fossils on Jebel Hafeet, Al Ain, UAE. The second rock looks like there is a criniod in it, but is more possibly a type of sponge. The first rock has quite a few things in it, including some type of coral. I would like to know what these really are.

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

A Devonian coral site in Louisville, Kentucky, USA
-
Corals such as this one I found around the Much Wenlock UK area are a species of Favosites (not sure which one though). In this instance the colony looks to have possibly grown around a crinoid stem. And could almost be described as ‘coral balls’ they are quite common ranging in size from 1cm to over 12 cm in diameter. I thought you might like to see it.

Some Fossils from the Plabutsch-Formation of the Palaeozoic of Graz, Styria, Austria (Devonian – Eifelian)
FranzBernhard posted a topic in Member Collections
Supplementing the post in “Fossil Hunting Trips” about the Devonian Plabutsch-formation in Styria, Austria (with some background info): http://www.thefossilforum.com/index.php?/topic/90431-some-fossil-hunting-in-the-plabutsch-formation-of-the-palaeozoic-of-graz-styria-austria-devonian-–-eifelian/ I would like to post some more fossil specimens in this thread. More specimens will follow from time to time (hopefully). The first two specimens contain abundant branches of the tabulate coral Striatopora? suessi. Field pics of these specimens are already posted in the hunting trip, but here you can see also their side views, showing the alingment of the individual coral branches. (I don´t know why pics don´t look good here, but if you are zooming in, they are ok). -
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.

i picked these up seperately the horse tooth in italy and the corals in barbados a few years ago, i was just wondering if they are fossils or modern as as far as i know the places where i was weren't known for fossils but the look kind of like fossils

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.

This all started over a year ago. I was selected as Member of the Month and a couple of TFF members from Texas invited me down to the big state to collect. I primarily collect in my home region, the northeast, but I've taken fossil forays to New Mexico, Kentucky, and Germany and was willing to consider a trip to Texas and the opportunity to visit some classic fossil sites and collect fossils that are outside my usual focus. I began planning this about ten months ago, contacted potential fossil collecting partners and did my own research on fossil sites, geology, and the types of fossils I would likely encounter. I had never been to Texas let alone fossil collected there. From the Forum I knew there was a lot of great hunting. Then there was all of the logistics, what to stay, what to bring. Since I wanted to bring back a lot driving appeared to be my best option, but I hadn't driven that far solo in over thirty years. Timing of my trip; mid-late September, came right after my daughter went away to college and I was in the middle of moving to a new place. So things couldn't have been more hectic. Finally, early in the morning on September 8th I set out. Things went okay until I was in Kentucky. Just as it was turning nightfall, torrential rain hit, traffic was stopped on the interstate for two and a half hours, and the last two hours of the trip I struggled with wet conditions and poor visibility. I finally arrived at my parents' house just after one in the morning. The next day on my way over to my sister's I took a small detour and stopped at an outcrop I was well familiar with in Leitchfield, the Upper Mississippian Glen Dean Formation.

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. -
Good Bye to my Crinoid Avatar
crinus posted a topic in Partners in Paleontology - Member Contributions to Science
Yesterday I signed over my prized crinoid (my avatar) along with 20 other specimens to the University of Michigan, Museum of Paleontology. With this crinoid I donated 7 other prized crinoids, 2 blastoids, 4 Tully Monsters, 2 brachiopods, 1 Mazon insect wing, 2 corals and a Cooksonia. These will then be loaned to the Museum of Natural History to go on permanent display in the new museum to open in 2019. Hardest part was parting with my avatar crinoid. It is what I consider the finest example of an Arthroacantha from the Arkona Formation at Arkona, Ontario. Not that parting with 4 exquisite Tullys wasn't hard. Hey, I offered and they came and took. I just wanted the museum to open with very nice examples of fossils.- 37 replies

Hi everyone. Here are some specimens from an Upper Campanian - Lower Maastrichtian reef in the Catalan Pyrenees, which species’ diversity amazes me. In fact, they are collected in a 30 meter-radius point. I’ve only been able to approximate their genus (thanks to @Pachy, mostly) . So, I’ll strongly appreciate any help. Well, let’s start with the tiniest ones: Heliopora sp. (=Polytremacis), an Octocorallian: Columactinastrea sp.: Synastrea ? (Only my guess)
