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!

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 believe this is an Evactinopora grandis from the Mississippian aged Burlington Formation limestone, but am not certain and would like other opinions. 2 of the "rays" are pretty weathered away and one is smaller than all of the others, but it looks apparent that it had 4 rays. I checked some of the references I keep downloaded on my phone, but none of them have bryozoan illustrative plates. I traded away the only other specimen I've found like this long ago, and didn't take any pictures. As found Dry Wetted

Middle Devonian Fossils - Swatara State Park (Pine Grove, PA)
Masonk posted a topic in Fossil Hunting Trips
Hi All, Took a trip last weekend to break rock @ Swatara State Park. Formation is Mahantango, however as I understand, the material itself is a roadcut transplant from nearby I-81. Spent about 5 hours looking and did fairly well overall. Main goal was trilobites (have yet to find any personally - goal achieved). Highlight is a possible Phyllocarid (suggested species - Echinocaris). I've attempted to ID mostly everything, however please feel free to correct me as I'm still learing. Few photos from the site: Looking down from atop the formation In situ Brachiopod - Cyrtina hamiltonensis? Brachipod?, Mucrospirifer?, Unsure of the 3rd photo. Coral and Sponge have been suggested. Possibly Receptaculites? Or maybe Bryozoan? Trilobite - Trinucleus? Trilobite - Greenops pygidum? Trilobite - Greenops pygidum? Trilobite - Greenops pygidum Crinoid stem?

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 :

Dark gray limestone matrix with unknown fossils, corals? bryozoans? something else?
SPrice posted a topic in Fossil ID
The Utah geologic map describes the location/formation as Manning Canyon Shale (lower Pennsylvanian and upper Mississippian) with black to brown shale with numerous thin beds of light-brown-weathering, gray, fine- grained, shaly sandstone, some lenses or beds of rusty-weathering grit, and one or more thick beds of gray to black, cherty limestone; at least in west contains some beds of light-brown quartzite; shale is carbonaceous with occasional nodules of marcasite. The area I was exploring the most was this type of rock - thick beds of gray to black, cherty limestone - as described above. There were several outcrops of limestone ridges along the rolling hills on the west side of Utah Lake. The area is BLM land with a sign at the gate reminding visitors that Shooting is Not allowed because of the ancient petroglyphs and risk of wildfires. Also, no collecting on this location. So I took only photos and left only footprints on this excursion. Here's the images of what I saw. Standing on an outcrop of limestone with Mt. Timpanogos in the left background, 11,752' summit. This elevation is around 4700' ASL. And just below the lizard's head is a fossil that I think might be bryozoa. There are also at least 3 lichen species mixed among the fossil. Brown bulbous, gray and orange ones. Zoom in to see the fossil best. Thanks for any responses. Steve

Hello, This is another old collection piece without provenance, and I was hoping someone could tell me if they recognize anything or guess its age. It's a plate of bryozoans, but I think I see a couple starfish peeking out from underneath.

My first (documented) fossil prep with hand tools bryozoan
C2fossils posted a topic in Fossil Preparation
I decided to document this prep so I am doing on a Bryozoan I found in Kansas. Not sure of the species, but that is part of why I am prepping it. Hope Y’all enjoy! this is what it looks like before I started. I will post an update once I get part way through.

In the annual TFF secret Santa I received a lot of cool fossils. One was a Mississippian aged bryozoan hash plate from the chesterian zone of the Bangor limestone. There are lots of interesting tiny details on the specimens so when looking through a microscope I spotted a tiny white sphere, only 150 micrometers in diameter. The question is, is it a fossil associated with the other bryozoans or is it just some synthetic foam or similar? The reason I ask is because it appears to be clean of matrix resting on top rather than imbedded. Stupid question? Maybe.

I went hunting yesterday. Running out of days, so I take any opportunity. Walked in over private land with owners permission. Hunted 5 hours "walking the river upstream". I like hunting in deep cool water, it is aerobic exercise. 1st location has shallow water and some colorful teeth. We were there 90 minutes. Between different locations , I frequently move finds from my collection bag to a ziploc bag in my backpack. That was fortunate since I left my collection bag and all the rest of my finds in the bed of Steve's truck. In a post 2 weeks ago , @Harry Pristis suggested Bryozoan as a ID for one of my Peace River finds (different location)... https://www.thefossilforum.com/topic/137631-peace-river-hunting/#comment-1458374 Yesterday I found a similar looking fossil. I almost tossed it back, but I am glad I did not. It is mostly round about 60-65 mm in diameter with a lot of attached concretion. I hung onto it because of this feature. Is this a holdfast, or Bryozoan remains or what ? I read that Bryozoa attach themselves to to anything hard on the sea floor like seashells or coral... Looks silicified.. Is that druzy ? Thanks for any and all Bryozoan comments. Is this identifiable to genus ? I hear there are 6000 + possibilities but this one in miocene or later.. A couple of other items in the box above... A Sand dollar or at least a piece of one...
