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!

I've been looking at these for sometime and am stumped as to what they may be. Found in Lansing NY. First up, photo's labeled #1 and #2 (hourglass shapes). I believe the matrix to be Tully Limestone. I have the scale written on one photo as 1.5 cm x 7 cm. They are of similar size. I wondered if they could be orthocone or crinoid but am unable to find any information or photos to compare them to as they are weathered. Both have the same somewhat zig zagging cross hatching patterns. Lastly, (#3) Believed to also be in Tully Limestone. I found what appears to be some type of a shell (2 cm x 3 cm) but it's shape doesn't resemble any of the gastropods, brachiopods, or bivalves in my area and I can't see any hinge. It appears that the outer shell has worn off and I think I'm looking at the internal mold? I don't want to try and prep it to reveal what may be hiding without any clue as to what it is. Thank you in advance
