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.

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- 1 reply

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...

Unknown "Growth" on Chesapecten Fragment - Boring Sponge or Bryozoan?
Echinoid Express posted a topic in Fossil ID
Hello there! On my revisit to the James River in Surry County, Virginia, I found something interesting on a broken fragment of a Chesapecten I can't quite narrow down myself! The area contains primarily Late Miocene Eastover formation, with a bit of Early Pliocene Yorktown formation as well. Most of my resources for the area's fossils I have are related to the molluscan fauna of the formations, so I haven't found anything reliable yet as to the identity. I initially picked it up thinking it was some sort of crab, but I realized I was looking at a much simpler animal after a few moments! The whole mass is about 5.334 cm (2.1 inches) "long" and 2.794 cm (1.1 inches) "wide", and wraps around the fragment. The fragment of shell has a lot of bore holes related to Clionaidae sponges, so I was wondering if this is what this is. I don't have a lot of experience with sponges, although I do have one from Tennessee I got from an online acquisition. I do know that the structure of sponges tend to be somewhat chaotic and overlap each other, and this appears to be the case. However, the unusual shape also reminds me of a bryozoan colony as well, so I just want some additional input with this. I don't know if there are described sponges from the area. I have a few angles taken with my trusty (and tricky) phone camera, and I tried out my USB microscope I got for my Aurora, NC microfossils. Although the quality isn't perfect on the microscope, I tried to find more "pristine" pores on the surface to take images of.- 4 replies
