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.- 21 replies

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.

Hey guys, I was wondering if ya'll could help me identify these. All were found in Texas to the best of my knowledge. I have what I believe to be the phyla of each but I'm not totally sure so take it with a grain of salt. Photo 1: Bryozoa Photo 2: Hemichordata Photo 3: Bryozoa Photo 4: Chordata, this is obviously a shark tooth I think but I'm unsure of the species

Back in May 2017, I brought back some nice fossil plates from Ohio, I believe Ordovician in age. First photo is plate 1. Next photo (of plate 1) shows a close-up of parts of the trilobite Isotelus, next photo - a nautiloid (unknown species), next photo shows valves of the brachiopod Strophomera, along with many bryozoan fossils. Next photo is a close-up of crinoids on plate 3. (Not much on plate 2). And last photo is of quite a few crinoids on plate 4.

Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you would like to see more, I'm busy posting a kazillion of 'em under the Nature Photography thread.

Day One; Locality Four Tizi N'Talghaumt Pass 19th February 2019 This pass runs through a slightly lower section of the eastern High Atlas along the course of the Ziz River which snakes its way right through to Algeria. These wonderful trees are common in the Sub Sahara, but I don't know what they are. We stopped by the altitude sign overlooking the Aoufous Oasis on the River Ziz. Whilst wifey and Abdulla admired the huge palmerie oasis, one of the largest in Morocco, Anouar and I nipped across the road to see what we could find :

Okay, I left this specimen where I could find it in the future, but the sun and atmosphere was such I could not get a crisp photo or achieve a decent zoom. It almost appears bryozoan in nature, but the regular spacing and rounded conic shapes might be something someone has seen before?

I should have posted this long ago, but am going to do it now, in the hope that then it is behind me and then I can look forward to future adventures. Due to ill health from 2012, finances and responsibilities, I have been unable to do any personal collecting except for this one wonderful trip which reminded me that I've still got it in me. In October 2016 wifey and I were relaxing in a bar on Tarifa beach, the southernmost point in mainland Europe, located at the south-western corner of Spain, opposite Tangier, the two Pillars of Hercules that are the entrance to the Mediterranean from the Atlantic. I noticed an island connected to the mainland by a man made causeway. it had a lighthouse on and some ruins, so I thought that being only a little distance, I'd go and explore. Here is the location, to the left of the picture is the Mediterranean, to the right, the Atlantic. There are no more location pics, I'm afraid, as wifey can't be prised away from bars very easily and she has the camera phone, but the island was closed to visitors without a guide or permit as it's a place for protected birds, the lighthouse and Napoleonic fortress ruins. But to the left of the causeway was a small beach with exposed rocks and even a little notice board explaining that the rocks were a Miocene oyster bed 5 to 10 million years old. My interest was aroused so I clambered about the beach and found the fossils in the next post. Very pleased with myself, I was, especially as I had no tools and the rock was really seriously hard. Had to use other bits of rock as hammer and chisels. And my breathing held out pretty well. I can still do this! Life's Good.

I found what appears to be a small sandstone on a Tampa Bay beach in Florida. It's about 1 inch by 1 1/4 inch. After looking at it under magnification I saw unusual vein-like strands on these raised tanner bumps on both sides. What is it? Is it a fossil? Thanks Guys! Front view angles

Brevicoceras casteri, with Hederella filiformis
Fossildude19 posted a gallery image in Member Collections
From the album: Fossildude's Middle Devonian Fossils
Brevicoceras casteri, with an example of Hederella filiformis. According to their 2008 paper, "Morphologies and Affinities of Hederelloid "Bryozoans" ", Paul D. Taylor and Mark A. Wilson "... interpret hederelloids as colonial, phoronid-like invertebrates, with retractable lophophores." Thanks to Scott (piranha) for the paper listed above.
