I purchased this specimen at a fossil convention and no longer remember what type of fossil the merchant said it contained. I noticed that the series of bands on the rock resemble images I've seen of Favosite coral. What do you think of these bands?

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

Pleurodictyum lenticularis Tabulate coral Lower Devonian Glenerie Limestone Tristates group Eastern NY -
My husband and I like to go on walks along the wooded dirt trails behind our home. Last winter, we stumbled upon a particular stretch of path. It was constructed using refractory bricks smack dab in the middle of the woods. It wasn’t until recently when we decided to revisit the area. One does not simply stumble upon an old brick path in the middle of the woods. It had to have once led somewhere. We did, in fact, find an old stone well nearby. Across from the well, there’s the foundation of a house that’s nothing but rubble. I also found an A&W Root Beer can amongst the rubble. It was the 1968 to 1995 A&W logo. Most of the bricks were branded, but I could hardly make out the wording. The name Louis was clear as day on quite a few of the smaller fragments, but the more intact bricks had lettering that was harder to read. I managed to find a single brick that wasn’t so weathered. I knelt down to read what was branded on it, but this little coral fragment caught my attention. It was wedged between the bricks in the center of the path, almost as if it were placed there intentionally. I don’t see how else it could have gotten there. After further inspection, the coral (a honeycomb coral) appears to be fused to an unidentifiable species of mollusk. Fossilized oysters and clams are common finds in my area, but this is the first fossilized coral I’ve found. FullSizeRender.MOV

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

Found this in a recent deep wash along Muskegon river just showing in the sand. Thought I had a small shelf till I pulled it out. It has individual cell walls standing in many locations and multiple free and open cells. 7 full perforated passages naturally formed in various locations and directions throughout. Not one recent chip or broken edge visible. I about fell over, is this for sure Favocites Favosus? Anyone seem something like this? Thanks Jason

Found two of these fossils now. Both on beaches that are probably Devonian in age. One is from SW Wisconsin on Lake Michigan and the other is in the Lower peninsula of Michigan from the shores of Lake Huron. Organ pipe coral or some sort of burrow trace fossil? Thanks!

Back in Oct. the Dayton Gem and Mineral Society had a field trip to the St Paul Stone Quarry in IN. Waldron shale. I've been slowly prepping my finds (along with other stuff) and finally completed my task. By far the most different piece I've found in a long time....a Rafinesquina-type brach covered in a bryozoan, with a Calymene face sitting on top, surrounded by pyrite. Size = 1.5" W x 1" D x 1" T. A complete, 3/4 prone Calymene. About 1.25" long. Some complete gastropods, all whose brown "shell" is pyrite. Some gastropods that aren't pyrite. A few brachiopods. Some crinoid calyxes. #7 Some some small pyrite brachiopods. And some tabulate corals.

I have some exciting news, thanks to the help of @TqB, who suggested that this tabulate coral I found in southwest Michigan glacial drift a few days ago is much more interesting and unusual than I could have imagined! After thinking about and dismissing a number of favositid possibilities, we realized that this is a cerioid syringoporid. Tarquin suggested that, due to the appearance of domed and/or infundibuliform tabulae inside the transverse and longitudinal sections, along with a few apparent mural pores and a possible syrinx (mural pore tunnel) structure, this might be a roemeriid. This is exciting because, besides a documentation from the Devonian Canadian Arctic on Fossilworks, this family has not been found before on the American continent, certainly not in the U.S. I emailed photos to the tabulate coral specialist Dr. Mikolaj Zapalski, who confirmed Tarquin's diagnosis! Here's his reply this morning: I think that your diagnosis is correct - it is a roemeriid. . . . as far as I can tell, it resembles Roemeripora - but the corallites are much larger than any Roemeripora I have seen. On the other hand I have experience only with some Polish and Russian taxa, so these species may be different. An isolated specimen may not be very helpful, but if further specimens are found, this could be potentially interesting for research. Mikołaj K. Zapalski Ph. D., D. Sc., FLS University of Warsaw, Faculty of Geology So, it looks as though this could be the first known discovery of a roemeriid, possibly a new species of Roemeripora, from the U.S.! Here are photos! I'm sending the specimen to Tarquin in hopes that he can prep it a little better or notice more details that I've missed. Best! Lisa An annotation of the previous photo, showing possible mural pore and syrinx structure:

Hi, all, A friend over on the Facebook group "Great Lakes Rocks and Minerals" recently posted this little silicified pebble she found along the shore of Lake Michigan, northern lower peninsula. The tiny pores got several of us on the group curious about whether we could narrow down a possible ID. Someone initially suggested heliolitid, but I think we ruled that out because there doesn't seem to be enough room between corallites for coenenchyme. We decided it must be some species of small-celled favositid, but is it possible to narrow beyond that? (My gut says probably not, since we don't have thin sections or better views!) I was curious about Astrocerium (referred to as Favosites venustus in older descriptions). It's described from the Silurian (Niagaran) of Michigan, which seems to fit with this style of silicification. Also, I think I see what might be interpreted as spinules in some of the corallites, but maybe this is just an effect of silicification. Plus, I guess spinules are pretty common in favositid species, so it could be any number of small-celled species of Favosites or Emmonsia. If anyone has examples of Astrocerium from their collection, I would love to see photos! P.S. Hope it's okay to tag you two, @TqB and @FossilDAWG -- wasn't sure of other coral experts to ask, though I know they are around! Thanks much! Lisa

Two weeks ago, I visited the Carmeuse Calcite Quarry in Rogers City, Michigan (Devonian). I spent an hour trying to dig under and around this specimen. With the help of another, I was able to dislodge it. It weights about 60 pounds and the top surface measures 38 cm x 43 cm. Looks like a Hexagonaria pericarinita, though am not sure.
