Semi-micro fossils (echinoid, shell, bryozoans, others) from Aireys Inlet, Victoria, Australia (Oligocene)
Oli_fossil posted a topic in Fossil ID
Hi all, Following up from my previous thread (https://www.thefossilforum.com/topic/139153-sea-urchins-sand-dollars-and-brachiopods-aireys-inlet-victoria-australia/), I returned to the same site (Aireys Inlet, Victoria, Australia) and closely inspected the fine, freshly eroded material on the sandstone platform/overhang (presuming ~20-25Mya), finding a number of interesting semi-micro fossils (1-5mm in size). Would appreciate any thoughts and ID! Will post in separate posts for clarity. First off, this beautiful little echinoid, ~3mm in diameter:

Sea urchins, sand dollars and brachiopods, Aireys Inlet, Victoria, Australia
Oli_fossil posted a topic in Fossil ID
Hi all, See attached - most of these are 5-10mm in size (cm/mm ruler in background). Found at/near base of sandstone cliffs near Aireys Inlet, Victoria, Australia. I have previously found Lovenia fossils in the area (and found a couple more today), but these are much smaller and flatter - more like sand dollars? IDs appreciated, and also suggestions re further cleaning - I just soaked them in water (~30min) and tried to remove loose material, but haven't done anything further. Would it be worth soaking/cleaning them further to try to remove more matrix? Also, do you think the small spines/tripods in 2a/2b/23c are the original spines of the sea urchin? I think 4 is probably the top lid of a similar brachiopod to 3/3a - does that seem reasonable? Cheers & thanks in advance, Oli

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!

Microtrilobites and Other Microfossils of the Pooleville Member
Isotelus2883 posted a topic in Micro-paleontology
Recently I acquired some microfossil matrix from the Bromide Formation, in Oklahoma. They were of the Pooleville and Mountain Lake Members, containing a very diverse fauna, mostly bryozoans and crinoid arm fragments. While searching through the matrix, my main aim was to find some of the small and young trilobites that are often found here. Also, I had bought a trilobite meraspis previously, from the same locality. It is an enrolled meraspis of a Lonchodomas mcgeheei, from the Pooleville member. Views of the Cephalon and pygidium.  Now, here are the finds. A Cyclospira parva, these were very common and found in all samples of the Pooleville Mbr. These are the trilobites of the Lower Pooleville. What may be a partial Lonchodomas mcgeheei pygidium. It is more likely a brachiopod fragment, however. A proetid free cheek, I think. This one is more likely to be a Homotelus bromidensis cheek. I'm not sure for this cheek. Eoceraurus? Here are the trilobites of the Middle Pooleville Member. Calliops armatus partial pygidium.It is rather fragmented, as sadly most of the microfossils in this material are. This may be a trilobite pygidium, but it seems now that I look at it, it may be a brachiopod. Now here is one of my better finds from the matrix. It is a partial trilobite, with the hypostome in place, unusually. Because the dorsal side is not preserved, I don't know what species it is. Here are the fossils of the Upper Pooleville Member. A picture of some of what I found in the sample. A healthy sized proetid free cheek. Two partial cephalons of Frencrinurus capitonis. Though partial, they still show exquisite detail, including several sharp spines. Last, there is this specimen. I am hoping it is a protaspis of some trilobite, but... Yeah. Doesn't look like it. These samples gave a clear picture of the Bromide Formation, and they were rich with fossil fragments, an excellent test for my microscope.

I have a lofty goal to collect at least one species of every brachiopod found in the USA that I can possibly obtain. I recently started a spreadsheet to itemize my collection. Spread sheet is attached. I will also periodically add photos. So far I've added: Cambrian, Silurian, Devonian, Permian, Triassic, Jurassic, Cretaceous, Paleocene, Eocene, and Pliocene Brachiopods of the USA.xlsx

As I've been cataloging my Devonian finds, in my research I've come across both mucrospirifer and mediospirifer. I'm not certain of the characteristics that would set the two apart. Can anyone provide some clarity or point me towards a resource that could?

Found these specimens when hunting just outside Danville, PA in a roadcut near the Susquehanna river. The location is Trimmers Rock formation. I'm fairly certain that these are brachiopods but I haven't been able to ID them with any certainty. Mainly at that site we find beautiful Mucrospirifer specimens. However, these specimens appear larger and don't, to me, seem to be Mucrospifier. Most of the research I've done has yielded IDs that seem to be typically smaller than what I found. The first image shows the two parts together, the second shows them side by side with the top piece flipped over, the third shows the bottom piece and the fourth shows the top piece. My best guess is Leiorhynchus.

Recently received this Brachiopod that was said to come from the Miocene Topanga formation. No species was listed and I haven't found any documentation that says there are brachiopods from this formation. I know there are some from nearby formations but unsure what those look like.

Is this a Bivalve or brachiopod? Seller lists it as both. Found near Somis California, no other information given

Dear fellow TFF members, I purchased this one from Creede Colorado but it is likely it does not originate there. I understand not having a definite location will make identification hard. Thank you for your time and expertise. Measures a little under 3 cm.

I have a find from my hunt last Tuesday that has me stumped. As I took a break from pounding rock I took a walk around the site to surface scan the surroundings. I saw a slab with a high concentration of spiriferids. I decided ti try to break the grouping off the slab. This resulted in a Mystery (for me) brachiopods coming out with one of the spiriferids attached as well as some imprints. The item does not photograph well but hopefully someone can make out what it is. It measures 3 inches across. Found in Middle Devonian Hamilton Group Moscow Formation. @Fossildude19 @Jeffrey P
