I'm still trying to find an example of a xenomorph for @Rockwood and I ran across this strange scene on my 57 pound rock (yes, we weighed it) from my son's land in Pulaski, TN. I know from what I learned here that the pink part is trepostome bryozoan fossils (I love the coloring, by the way!). It appears to have almost a shell over it, though? And in another place a portion of it is "peeking through" the shell like substance? Is that another type of encrusting bryozoan? If so, would that make this a xenomorph? Thanks! Ramona

The weather is exceptional in southern Ontario, these days. 25 degrees C! That’s 77 degrees Fahrenheit to my US friends and for here in November it is exceptional! We decided it was a great day to go to Big Bay which is situated on Georgian Bay between the Owen Sound and Colpoys Bay a beautiful place down a gravel road; it can be busy in the summer but we knew today it would be quiet. The trip was purposeful because I know it is just full of water washed fossils and I wanted to post pictures of what is there. I wanted to show you all how prolific the Silurian Ocean was. I also included a couple of photos of the beach it’s self. Hope you all enjoy.

I hope this is allowed in the Fossil ID portion of the forum. I have learned so much here that I just want to "give back" for a moment. I am a photographer by trade and I want to share a few photos that show the beauty of bryozoa - trepostome bryozoan fossils in this case (thanks to the help from folks on this forum!) These are not huge and monumental discoveries, but the more I study them, the more I am fascinated by them. The more I learn, the more I NEED to learn. These creatures are beautiful in form, color, and substance. I have no questions in this post - just wanted to say THANKS in the way I know best - through my photographs! These are macro photographs - up close and personal with a very large, bryozoan loaded rock from Pulaski, TN. I am not reducing the resolution as much this time, so this will take a few posts. Blessings! Ramona

Identification Help Requested ( Large Mississippian Bryozoa?)
Thomas.Dodson posted a topic in Fossil ID
Hi everyone, These unidentified specimens were collected in Union County, Illinois. It's from Mississippian strata, likely the Ste. Genevieve Limestone or St. Louis Limestone. I haven't been able to track down a proper map of this quadrangle yet. The smaller specimens resemble mound bryozoa like Prasopora and the cups of all of them display concentric layers like related bryozoans. There aren't any pores visible so I've been thinking about bisecting one of the smaller specimens to see if any radiating zooecia are visible. What does everyone else think? Does anyone have any idea on what they are?

I had a chance to look for rocks in a new location today and WOO HOO, I found a huge rock that should keep me busy for a while! This baby is filled with tons of interesting things! I am going to start with just a couple of questions that I THINK I may know the answers to. Are these samples of a type of Fenestrate Bryozoan fossil? If not, maybe coral of some type? These were found at the base of a small mountain/hill in Pulaski, TN, where no fossil hunting has been done (yet!). If these are a type of Fenestrate Bryozoan, it looks like they have more of the structure intact than I am used to - thoughts on that? Thanks again! Ramona

Hello all! I found this pretty cool bryozoan back in July and I decided to give it a prep. Its really easy matrix to work with so its good practice for someone like me who’s only done a handful of preps. Like my past preparations, this will all be done manually using mainly safety pins. Fenestella sp. ? Middle Devonian Hamilton Group Moscow Formation Windom Shale DSR, Lebanon, NY Enjoy!

I hope, hope, hope that I don't wear out my welcome by asking questions about rocks with Fenestellan Bryozoan fossils in them! That's about all I got around here, but I do get other items IN those rocks that I don't recognize, like this one. Thanks so much to those guys who take the time to read and answer my questions - over and over again, LOL! This is yet another rock that I found in my yard and it is filled with what looks like layers of a variety of fenestellan bryozoan fossils? I have included a photo that shows what I am talking about, so please correct me if I am wrong! There is this shell like structure, though, that I am puzzled about. Is it part of the fenestellan colony or something totally different. I have studied the post about 3D structure of the fenestellan colonies and I don't think there is anything like this in them... But I could easily have missed something. I have more photos if needed? I also think I see some Rugosa coral on this rock, along with a few other things, but I will only ask one question at a time. ;-) Thanks! Ramona

I think the curved part of this rock is probably just a coincidence, but since I have never seen anything like it before, I thought I would check. Like a lot of other rocks I find, it seems to have a layer of limestone fenestellan bryozoan fossils encrusted around it (that's about the only way I know to describe it) and lots of tiny impression fossils on the inside of the rock. Can anyone help me figure out the rock's story? What might have caused the curved and layered appearance? Is that just a coincidence? Or is this a particular "thing"? Found in Madison County, Alabama. I will post more photos in follow up comments. Thanks! Ramona

I am learning to pick apart the items I find in the limestone fossiliferous rocks from my yard, but I see some things here that I am not familiar with. What is the tubular item at the bottom of the photo? And what are the tiny round black things? They look like poop, LOL! One of them is inside of a crinoid fossil, but it may have fallen there? This was found in Madison County, Alabama. I find fossiliferous limestone mostly with fenestellan bryzoan fossils, crinoids, coral, etc. Thanks! Ramona

I found this stone with several circles and some pattern. Could it be a coral or is it a bryozoan? Seems too small for bryozoan. Anybody can help identify it? Size of diameter about 3cm. Late Ordovician.

Found this in our yard in Madison County, AL. We have tons of Fenestellan Bryzoan fossils, crinoids, etc (as you can see in this rock, also). Is this embedded fossil object a more complete bryozoan fossil? It looks like it would easily fall out, but I don't want to mess with it. This is a macro photo - the embedded object is about 3/4 inches long. Thanks! Ramona

I went up to the UP this week doing mostly sightseeing with my friends. They were aware of my predilection for rockhounding so we often made stops to areas that might bear good fossils/agates. In particular I knew there were some 'lagerstatten' in the Stonington Peninsula region of the UP. The most important formation I know of is the 'Big Hill formation' (correct me if I'm wrong). Some links about it here: https://www.researchgate.net/publication/308005515_A_new_Lagerstatte_from_the_Late_Ordovician_Big_Hill_Formation_Upper_Peninsula_Michigan https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6325806/ Now, I didn't have enough time to bother my friends into finding these exposures (and as far as I know, rock collecting in a national forest is not allowed)... However, while we were driving south on County Road 513 T on the west side of the Stonington Peninsula, headed for the lighthouse, I spied a small hillcut on the east side of the road. The hillcut was directly across from a large cemetery-- we pulled over and I had a quick look at some of the rocks there. The hillcut itself was about 20 feet tall, and maybe 600 feet long. I could see near the top of the cut a few feet of limestone bedding planes jutting out from the escarpment. Weathering had amassed a slopped pile of clay and fossils that nearly filled the ditch at the base of the hillcut. On the surface, I saw many brachiopods (different kinds of Platystrophia, possibly?) some of whom were larger than 2 inches across. I also found some small bryozoan colonies and possibly pieces of isotelus gigas molts. The pieces were too small to tell, I am unsure if this particular roadcut could yield anything fully articulated. The rock was very weak and almost clay like. Does anyone know about this roadcut? What formations might be there? I took a few small samples with me but I didn't want to start excavating, obviously. If anyone is interested I could post some pictures of what I picked up, or I could send more detailed directions. Best, Foss

I found this stone with several strange forms. Could they be bryozoans or corals, ans which kind? Martin

A few years ago I collected with the NYPS at a quarry exposing some Helderberg Group limestone. I failed to label some of my finds. I have a best guess on the trilobites but I was hoping to get some confirmation. I have struggled identifying a few of the brachiopods and a bryozoan and I could use some help with those. Any help is greatly appreciated. #1 - some type of bryozoan but I am not sure which one #2- ??? #3- ??? #4- Paciphacops logani? #5- Odontocephalus sp.? #6- Dalmanites pleuroptyx?

Hi everyone! I found this piece yesterday at my new spot along Etobicoke Creek here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). It's a bryozoan of some sort with some crinoid stems on it, along with an imprint that I think is either a Cruziana ichnofossil or a weathered crinoid stem imprint - what do you all think? I've boxed the imprint in red. Thanks in advance! Monica Views of the imprint: View of the other side of the rock/bryozoan: Close-up of the bryozoan:

I picked this up at the flea market. He told me it was petrified moss...which I dont think it is. Im thinking coral but I wasn't able to find the answer after some research. Its from Arizona and was collected in 1968 and its jurassic in age. Pretty cool fossil.

Identification for a large variety of different fossils (Georgian Bay Formation)
Emthegem posted a topic in Fossil ID
Hello all! So I've been looking through my collection and noticed a bunch of fossils that I haven't yet identified yet. Some of them are quite peculiar, as I've never seen some of them until now. This'll be a long post with 12 different fossils in need of a name so brace yourselves hahah: All fossils found in Toronto creeks - Ordovician Era - Georgian Bay Formation 1. I thought this was the typical Treptoceras crebriseptum that I always find at my local creek, but when I cracked it out from the matrix I noticed it was perfectly smooth. Maybe its the living chamber of the nautiloid? 2. I honestly have NO clue what this is. Never seen anything like it. I thought it was nothing, but it seems to have such a defined symmetrical shape... ...

Unidentified large bryozoan from the Lower Devonian Kalkberg formation. Collected 5/31/20 Rickard Hill Rd. Schoharie, NY -
Found these Midwest, likely Iowa, from either Carboniferous or Devonian rocks. Any help in IDing them would be much appreciated. Thanks!

Any help with identification of the following attached Bryozoans would be greatly appreciated. 001: Collected from Bungonia NSW Australia and is Upper Silurian in age. 002: Collected from Bowning NSW Australia and is Upper Silurian in age. (possibly a Penniretepora sp.) 003: Collected from Bowning NSW Australia and is Upper Silurian in age. and again, thank you for any help given.

Age is Miocene-Pliocene. Bryozoan is an immediate thought, but I'm pretty sure that they're quite rare post Paleozoic, and this kind of encrustation is very common in the locality where the specimen was found. Here is a picture: Bonus thanks if anyone knows with some certainty what the bivalve itself might be from the photo, though I doubt it.

Today I was able to get out to the outcrop along Rickard Hill in Schoharie, New York. I didn’t find a ton of interesting things because I was looking in a more crystalline layer of the Kalkberg formation that had less abundant fossils. I found a handful of nice orthid, spiriferid, and atrypid brachiopods and one fenestellid bryozoan. Next time I go I’m going to try and get into a different, more fossiliferous layer because the crystalline rock is hard to break and when it does it breaks randomly, often damaging the fossils.

Today on a hunt in the lower devonian of new york, I found on of the most unusual piece and I can't decide if its bryzoan or possible placoderm.

Hello everyone, This will be my final ID topic for a while as I am trying to get some labels for a few fossils in my collection. Here are two fossils of marine animals, the first I believe is a bryozoan, I have no idea of the location or age of either but this piece has a strong resemblance to the devonian Fistuliramus and Eridotrypella from Morocco. The second is a very white and chalky horn coral, I am guessing that it is from somewhere in the US as the person I got it from mostly has US fossils. Does anyone recognize the fossilization on this piece? I am trying to identify where it is from.
