For the Columbus Day weekend my girlfriend planned a three-day trip down to Southwestern Virginia as a birthday present to me. The plan was to do a little sightseeing, go on some hikes, enjoy the fall foliage, and, most importantly, collect some fossils. Unfortunately Hurricane Delta had other plans for us. As the weekend approached it looked like the entire weekend would be soaked with rain. We tried to change our reservations, but we were not allowed to postpone. Not knowing what to expect for the weekend, we made our trip. Sunday was to be my big day of fossil collecting. It was also the day that Hurricane Delta was expected to pass through Southwestern Virginia... Lucky for me, luck turned out to be on my side (at least in part). I had an all-day fossil trip planned, but due to the weather, I had to cut the trip in half. After a later start to the day than I had hoped for, we headed towards two sites that I had identified for the day. Both were exposures of the Middle Ordovician Benbolt Formation. A few showers on the drive but for the most part the rain held off while we collected. Our first stop was a large, open road cut. The limestone there is just covered with brachiopods, trilobite pieces and bryozoa I thought the number and orientation of all of the bryozoa in this hash plate were very cool There were a lot of bryozoa at this site. Some small and some large, like these thick pieces of Batostoma sevieri My favorite bryozoan found here though was Ceramoporella sp. This piece of Corynotrypa inflata comes in a close second. This bryozoan is encrusting and was often found on the inside of loose valves of larger brachiopods I am still trying to identify all of the brachiopods. I believe the left one in the second photo may be Strophomena amploides and the bottom center one may be Rafinesquina champlainensis Another really interesting fossil was this undetermined sponge One of the unfortunate things about this site is that because it is so exposed, the fossils there weather very quickly. This is most apparent on all of the trilobite pieces. Here are two cephalons and a pygidium of Illaenus fieldi I think this is a right cheek and eye of Eoharpes sp. Here is an additional mystery trilobite piece

Discoporella ? Pliocene/Pleistocene from Aurora Fossil Museum micro matrix Aurora, North Carolina Thanks to @Al Dente for the ID -
Recently I have taken interest in fossil hunting after discovering a plethora of fossils from some farmland in Southern Indiana. It is my understanding the fossils are from the Devonian period. My grandsons (5 and 6 years old) and I have collected several specimens I’ve the last couple of months. I have been searching the Internet for weeks trying to correctly identify our finds and just when I think I have something identified —I find other possibilities. I would like to make displays for the grandkids and label our other collections appropriately. I am in hopes this community would help identify the specimens, and provide advice on how best to label the fossils. I appreciate any assistance that can be provided. Thanks. —Bill Shingleton PS: All the fossils depicted are from Jeffersonville, IN.

Hello, FFers: I'm wondering if anyone can tell me anything about these filamental fossils from the U. Ord of Kenton County, Kentucky. Given the structure under the mike, I'm guessing bryozoan, but I'd never seen anything quite like this before. Can anyone tell me more? Including, maybe, an ID? (Or a different direction, if I'm wrong about their being bryozoa.) The scale in the first pic is in mm. Thanks!

Last weekend I got a chance to do some fossil hunting in a creek in Greene, New York. I am a unsure if the exact formation I was in but I know it was upper Devonian. Brachiopods were quite abundant, especially spiriferid ones. I also found a couple nice bivalves and some bryozoans/corals.

I was able to get some much needed "me time" yesterday. With all the worries of the world I have been in a foul mood lately, but I am happy to report that my mood has brightened significantly. . There is nothing like crawling around on a road cut, and hunting fossils, to really lift one's spirits! I spent a couple of hours at an upper Ordovician road cut that has been on my list to check out. It is an exposure of the Grant Lake Limestone. Shortly after I arrived, I realized that I was in for a real treat! This particular exposure is more fossil than limestone. Brachiopods are everywhere! Vinlandostrophia dominate the exposure; with Hebertella coming in a close second. Other brachs are also found, but less abundant. Orthoconic nautiloid fragments are frequently found and bryozoan encrusting is a common sight. I also found a few gastropods, and one trilobite piece that I am excited about. Unfortunately I did not take pictures in the field. It was a conscious decision. I just wanted to enjoy my time, relax, and focus on the hunt. I'll get some next time as I will definitely be going back. I did take a few pics of my better finds at home. Enjoy! First up are the Brachiopods. I found some nice whole Vinlandostrophia, and Hebertella, and what I think is Rafinesquina ( @Tidgy's Dad ) . I also took home a few single valves for study of the internal structure. I think with a little bit of clean up these will look great! I was happy to find some orthoconic nautiloids. They have been sorely lacking in my collection. I will have to research what species are found in this formation to come up with an ID. I have a few ideas, but need to confirm. Here are a few gastropods and bryozoans. I can't resist the alluring whirls of a gastropod. They seem to be uncommon in the areas that I hunt so I grab them whenever I see them. I believe these are new species of bryozoa that I will be adding to my collection. Which is exciting! Here is a tril-o-bit that I found. I'm very happy with it. Typical trilobite fragments from this area are not usually identifiable. Except to say they are possible trilobite pieces. This is a cephalic doublure of an Isotelus. Thanks to @piranha for help with the ID. All in all it was a great time. I got to relax a bit, forget my troubles, and brighten my mood. I also added some nice pieces to my collection. It was a good day!

My first attempt here. I'm having a great time exploring the Mogollon Rim area near our home here in Arizona. The Kohl's Ranch area near Payson is famous for its Carboniferous brachiopods, but I have a piece that has obvious bryozoans. But in this photo there are two pieces that are "fern" shape. The longer of the two is about 1/2 inch long. They have me stumpred.

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

I recently purchased some Mid Devonian silica shale pieces with trilo-bits from @connorp. And by recently I mean last month... last year..(January is always confusing that way). Just several small pieces with partial molts I'm using for practice prepping. So after picking at a few all year... one of them has gone from a practice piece to an almost show piece. 1st pic is the original sales pic with the piece circled. In it you can see part of the trilo-bit, but not really anything else. I got a nose w/ a partial eye (base only), bryozoa scattered about here & there, some tiny crinoid pieces and a thing I can't decide on. Pic labeled with a 1 is an overall shot, 2 is a close up of the nose, 3 is a bryozoa (I think) & 4 is the question one. The entire stone is 7.5 cm x 6.5 cm. Nose is 1 cm wide, the small bryozoa fan thingy is 0.5 cm wide & the question one is 2.5 cm long. I'm using a needle in a pin vise, fine scribe tip in another pin vise, dental picks & a stiff(ish) nylon brush with hydrogen peroxide, 3x led magnifying lamp & 10x loupe.

Hi All, I picked up this rock in my back yard a couple of days ago. I picked it up because I saw a couple cross sections of rugose coral and some fenestrate bryozoan fossil pieces. When looking at it later, I noticed this feature. I haven't found anything like this before. Is this just a different type of bryozoa? These little marks also look like some tiny Platycrinite crinoid pieces. This was found in Howell County, Missouri, USA. It came from the Ordovician Period. These lines measure approximately 23mm in length and measure approximately 0.79mm wide. The individual spots are oval in shape and measure approximately 0.38x0.79mm. I don't know if it shows well in the first image, but this feature appears to be in a fracture in the host rock. There is still some rock covering the feature in the fracture. Any assistance or direction that you can give me is greatly appreciated. Thanks for your time, Doug

Are these two samples (from northcentral IN) bryozoans? The first image is 18 cm x 12 cm; the second is egg-shaped, same dimensions but has a dome. Thanks!

I am studying a tiny area of a fossiliferous limestone rock from our yard and trying to determine the different items in it. The fan shaped item in the lower left corner didn't really look like the fenestella bryozoa that I am used to seeing, so I did a bit of research. I found a page with a similar image and was wondering if I am correct (or even close) in identifying that particular item as a cheilostome? Here is the page I was looking at: https://www.researchgate.net/figure/A-sample-of-bryozoa-sand-sample-number-71-from-a-depth-of-130-m-on-the-Lacepede-Shelf_fig1_238417060. Would the fenestella bryozoa be seen next to the cheilostomes? And what about the little flower like item that is above and to the right of the fan shaped item? It's kind of hard to see - I can circle it if needed. This area covered by this image is approximately 2cm across. That is what caught my eye - how tiny the fan shaped item was. This rock is from Huntsville, AL. Thanks guys and gals!!

Hello gang, This is one of the first fossils I prepped a long time ago. It may not be the best job, but I still like it. I know it Bryozoa, but not much else. It was an unprepped flea market find. Any ideas?

Any ideas about the type of Bryozoa in the left rock? I found several of these long string types this past weekend in the Devonian shale at Beltzville State Park in PA. Very different from the other bryozoa I have found there in the past. Thanks, Mike

Are all of these bryozoans? If yes, what are their specific names?
Pippa posted a topic in Fossil ID
Hello, I think the rocks below contain at least two different species of bryozoa fossils. Is it possible to identify them by name? If not, would better specimens with more visible detail make that possible? Some, as in the first pic appear as b/w, narrow lacy (sometimes striped) leaf like shapes. Others, as in the second pic, look more animal like, sometimes "hairy", but sometimes are just wide blobs with no visible detail. I'd really appreciate this forum's fossil experts superior knowledge. Thanks in advance. -
Atactotoechus fruticosus Took me about 12 hours to reassemble this Bryozoan colony. Found Tuesday 8/27. The majority of the colony is very nice with all the fronds complete to tips. Its getting heavy with every new piece added. I was lucky that most of the colony was in shale and preserved from weathering. Thank you and Happy Collecting.

How to properly dissolve matrix to reveal microfossils? Tips & tricks needed
ziggycardon posted a topic in Micro-paleontology
Hi, a few days ago I went on my first ever fossil hunting trip to Eben-Emael, a Limestone quarry in Belgium that dates to the Maastrichtian and is part from the type location (the historical ENCI quarry being only a 3,5 km to the north. The trip was orginized by the BVP (Belgische Vereniging voor Paleontologie) and a short report of the trip with phot's and some of the finds can be found in this topic by @Manticocerasman who I was lucky enough to tag along with, cause I doubt I would have found many mention worthy fossils without the guidance of Kevin. But since I am into microfossils I decided to collect some samples of the limestone without the obvious fossils home to later be able to look for microfossils as it should be quite rich. I think I have around 1 - 3 kg of matrix left to look for microfossils. But I have never myself dissolved matrix, and although it seems easy, I don't want to make any mistakes. During the trip they advised me on two different approaches, depending on what kind of fossils I wanted to find. One approach was dissolving in water and the other in vinegar, but now the seeming obvious question. How exactly do I do that? Should I just take a bucket of a glass, fill it halfway with said liquids and just wait? Or should I use a sieve and lay the block there so only fossils remain in the sieve and the rest goes to the buttom. Does the limestone just dissolve or does some kind of putty residu where the microfossils will be in? If so, how to properly remove the fossils when you pour out the liquids without pouring out the fossils? I know I have many questions and some might be very obvious and straigh-forward, but I really haven't done this before and I would like to do it the right way from start. So thanks in advance for any tips & tricks, I would really appreciate any help!- 4 replies

Hello gang, As promised this is where I will share specimens from my personal collection, my grandfather's collection, and the collection that was donated to the university I work for. The latter is interesting as it is literally boxes of rock and fossils, with no information and my university does not have a geology or paleontology department. I'll be updating it every so often. Enjoy! NOTE: Some of the donated items have old school "labels" on them. If you see initials or such that you recognize, please PM me, as I am doing my best to properly catalog them properly as part of my job!

Tonight I found a new limestone ledge sitting 6 inches from a stream water level. My father and I started hammering away at the shallow edges and removed a ton of interesting specimens. While there were some nice cephalopods, lots of brachiopods and clams, this piece caught my eye. I’ve read about Bryozoa and I’ve seen similar things on fossil plates. I believe I remember seeing pieces of them in limestone while digging, but never anything big. So, is it a Fenestella? Or something else? I’ve never found one worth showing. I saw a species list for it and it is very long.
