From the album: Lime Creek Devonian Rockford Iowa
Lioclema occidens common. One weird thing about Lime Creek Formation is the numbers of bryozoan species which was much more diverse in Ordovician become much more less diverse even thought similar environment - muddy subtropical seas. This is the largest rugose bryozoan left. All the others (so far not identified yet) are much smaller, less than .2 of a centimeter in diameter. -
This is another fossil that has me stumped. I think that there is a possibility of bryozoan, because of the pits, but I remain unconvinced. It is from the Leighton Formation, which is Pridoli. The pictures below are of the fossil under raking lighting, to show the pits, then of it under lighting from directly above, and finally with scale (mm). Thanks everyone!

A few weeks back, I happened to accidentally find a fossil while out trail running - my first ever! I found this forum to get help identifying what it was, and figured that would be the end of it. But it turns out that the trail I have been running on for 20 years has lots of fossils, and now I can't stop seeing them! I have been reading this forum and following up with other resources to try to educate myself a little. My mother-in-law was super interested when I showed her a couple that I had picked up, so we decided to go back out there for our very first newbie fossil hunt. My MIL, in her late 70's, hiked up to the top of the mountain with me like it was nothing, and we had a great time poking around. The area we found these in is Devonian, Foreknobs formation. Here are a few of our finds - lots of brachiopods, more crinoids than you can shake a stick at, and some bryozoans! And it sounds like my MIL can't wait to go back - I think this will be a fun activity for the two of us.

Hello guys! These are the specimen from Ile Bizard. This seems to be some kind of Bryzoan, forming a shell structure. #1 1.1 1.2 1.3 1.4 1.5

From the album: Bryozoan of Minnesota Ordovician
Batostoma species from Mifflin portion of Platteville Formation. Since there hadn't been any official researches into platteville bryozoan, I would assume this to be a early forerunner of Batostoma fertile as it looks very similar to it but on average smaller. One rock have a different species running parallel but camera couldn't get more details. -
From the album: Bryozoan of Minnesota Ordovician
Unnamed species. I keep getting in over my head with all the vocabulary so most likely not new. I only found this species this year in a new Decorah dig site location. I would had almost tossed it aside if not for the first piece I found which is much longer than the usual rugose decorah twin cities Ordovician bryozoans. On closer inspects it is so different from my Batostoma species. Rarely branching which is very unusual for a rugose bryozoan, very variable wall thickness as seen as under digital microscope. Only found in this one location. -

Another digital microscope of Phylloporina sublaxa, this time a bleached out one. Note the zoarium. -

Digital microscope close up of Phylloporina sublaxa. Its the best I could do. -
From the album: Bryozoan of Minnesota Ordovician
Stictoporella frondifera. Very localized abundant in lower Decorah formation Minnesota, Ordovician, Twin Cities. -
From the album: Bryozoan of Minnesota Ordovician
Phylloporina sublaxa uncommon Decorah formation Ordovician Minnesota Twin Cities. I tend to find them in pretty small pieces and obviously easily overlooked. Much more finer laces than Stictoporellina cribrosa. -

The best I could do with digital microscope of close up of Batostoma fertile specimen. -
From the album: Bryozoan of Minnesota Ordovician
Batostoma fragile Decorah Shale Ordovician Twin Cities Minnesota. When comparing all bryozoan fossils from Ordovician this one stands out as having the largest zoarium. (fossil terms for the pores). Its also the largest branching bryozoan I had found in terms of masses. One thing I have noticed with this is compare to "Batostoma minnesotense" It tend to be ,more lumpy and more flexible into forms, even at times mistook for Prasopora conoidea if not for its larger zoariums. -
From the album: Bryozoan of Minnesota Ordovician
Prasopora conoidea - average sizes that makes them noticeable. Sometime in the future I will have to examine closer - but I suspects smaller colonies may exists on harder surfaces than most people thought. From my examinations Prasopora conoidea strongly prefers muddy sediments, as I hadn't found any in carbonate rich rocks. Seem to strongly prefers brachiopods of any sizes as starting point for their colonies though uncommonly occurs on bryozoans as well. Abundant in all layers of Decorah formation. -
From the album: Bryozoan of Minnesota Ordovician
Prasopora conoidea from Decorah Formation. Those are the largest ones I have found - seemly? (not 100% sure) only in upper Decorah Formation. The middle one is the largest I had found so far. -
Hello, friends! This bryozoan is tiny, about a mm wide. It seems to be made up of overlapping tubes arranges diagonally across the zooarium. It come from the Southgate Hill road cutting, St. Leon, Indiana and I think is from the Liberty Formation, Cincinnatian, Late Ordovician due to other species found in the same piece of rock. The other species include Xenocrinus baeri, Hebertella occidentalis, Zygospira modesta, Graptodictya perelegans, Bythopora deliculata, Batostoma sp. and Stictopora emacerata. I think. Thank you for looking.

Fossil forum, I recently found an interesting fossil. I was thinking coral or bryozoan, but was unable to identify it correctly. It is from the Leighton Fm Maine (again), which is Silurian. Any help would be greatly appreciated. Here are some pictures of it:

From the album: Bryozoan of Minnesota Ordovician
Strictoporellina cribrosa uncommon Decorah Formation. Least common of the porous frondose types. Pretty solid flat with pores ridden it. No other variability in shapes. -
Hello, I have personally collected these far from perfect samples on some hiking trips and from around the field I work in. I have included a Die in each picture that is 2cm³, and have the corresponding number on the die to each specimen/picture. Any help with ID would be cool! Thanks in advance! 1. Stromatolites? Devonian - Palliser FM. 2. Bryozoan? Devonian - Palliser FM 3. ?Buchia? Cretaceous - FM unknown could be Three possibilities and I am not familiar enough with how the formations lay for the elevations I was at. Bivalves were found in two very different locations but still I believe Cretaceous.

I love fossils and I love macro photography! If anyone is interested in having this photo to make a puzzle out of, let me know and I will send you a full res copy of it. This is part of a rock that I found in our backyard in Madison County, Alabama, just a couple of days ago. You could spend a lot of time studying it and finding a wide variety of fossils - mostly bryozoan - so I thought it might make a fun puzzle for these pandemic times. I'm not sure how this works, but I think there is a messaging option here where you could give me your email address so I could send the full resolution photo, right? It's large (over 10mb), so there's no way I can post it here. Blessings Ramona

I dug this rock up in my back yard today in Madison County, Alabama. I was not surprised to find the typical fenestellate bryozoan fossils that I normally find, but I am puzzled by a couple of things. I will post a some photos to show the bryozoan fossils on the rock and then macro photographs of the parts I have questions about. The pod like structures remind me of some that I found on another rock from TN, but with encrusting bryozoan fossils... The other "thing" looks like some type of stem? Are these structures of the bryozoan colonies? I see one crinoid fossil on here, too, but that stem didn't really look crinoid-ish to me? I have been known to be wrong (often), though... Thoughts and suggestions appreciated! Thanks!! Ramona
