  1. Scylla

    Oldest Bryzoan

    New Bryzoan fossils push back age of oldest Bryzoan and give clues to origins. https://ecoevocommunity.nature.com/amp/posts/a-cambrian-origin-for-the-colonial-phylum-bryozoa
  2. I found this water filled agate geode/vug in an area known for 22-26 million year old coral and shell fossils. I acid etched it from a chunk of limestone. It has unique patterns I have not seen before. It might not be a coral fossil, but that is my best guess. It could be a Bryzoan which have also been found in the area. It's 1.5 inches long. I'm hoping the detailed patterns and side structure can help one of your experts figure out what I found. The outer form also makes me think of coral, but brozoans would also fit.
  3. I am on a mission to determine if I have different types of fossils in the bottom of our creek bed than I do in the rocks in our yard. This is the first rock I have photographed and I saw a bryozoan fossil I didn't recognize! At least I think it is bryozoan... I have learned not to make assumptions... I recognize the fossils on the right of the photo as fenestellate bryozoans. The portion on the left is what I am not sure about - the honeycomb like part. It has some of the characteristics that I am used to finding in the fenestellate bryozoan fossil rocks, but it also reminds me of the trepostome bryozoan, since it has the appearance of being encrusted. I also read about Monticulipora bryozoa and lamellar cyclostome but I don't have the depth of knowledge to know the difference. And then there is coral? Honeycomb coral? Seems like this is too small? The small rock on top was part of the rock at first but it fell off when I was cleaning it. with a toothbrush and water. Also, as a bonus question - I get those, right?!! - what might the two types of lines on the side of the rock be? There is one type that is a single dashed line but the other one is a pair of dashed gray lines that separate and then come back together. There are quite a few of each of these on the rock - I can provide better photos if needed for identification. For those who have not been bored by my bryozoan posts yet, LOL, this rock was found in Huntsville, AL. Thanks!! Ramona
  4. 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.
  5. Folks, These photos are from a small section of shale I picked up in Northeastern Oklahoma. The shale contains marine fossils of Pennsylvanian age. I have questions about a couple of the labeled objects. I’m thinking the center one may be a brachiopod (or possibly a bryzoan--it's hard to tell because of the crinoid plate resting above it). The one on the right looks to me like a bryzoan. However, I’m a novice at identification so I’d appreciate any opinions. The putative bryzoan appears to have grown on the crinoid stem. Best wishes.
  6. I keep finding rocks with these bowl-like structures on them, so I took one to examine more closely. I cleaned it well with my vinegar/water solution and then started removing as much soft matrix as I could with a dental pick. These bowl like structures have a fairly thick edge to them. Once I took macro photos of them, I could see that they do seem to be comprised of fenestellan bryzoan fossils, although I believe I do see some crinoids, too (not sure if I included those in the photos). I have been learning about the fenestellan bryzoan anatomy, but I am not sure where/if this fits in. I will post photos of the "bowls" and the surrounding areas, where I have removed some matrix. You may need to zoom in to see the tiny details. Thanks for any information! (Located in Huntsville, AL) Ramona
  7. I am trying to wrap my head around what these things looked like in "real life" so I can recognize them better. This is a limestone rock with what I think are fenestella bryozoan fossils, found in Huntsville, AL. Mississipian age. This photo is looking down at what I call the "top" of the rock. The next photo will be from the side, looking at the same area but from the "inside" of the rock. Can anyone point me to a site where I might find a diagram of these to better help me understand what they looked like? Thanks! Ramona
  8. This is my first post in the Fossil ID section - I am SO excited to find this resource! A have found a few very helpful folks in other places, but this group is a huge wealth of information! A bit of background - we moved into a house just outside of the city limits of Huntsville, AL, a couple of months ago. After finding a couple of fossils laying around in the yard, I decided to investigate the wooded area at the back of our property a bit more. Whoa!!! There is a creek bed on the property and the closer you walk to the creek the more rocks you have to walk over. Every single rock I picked up had some kind of fossil in it. The sides of the creek have rocks embedded in them, too. It seems like someone may have looked around a bit in the past (found a small pile of rocks) but many (MANY) of these rocks are in their natural state. Most of them, in fact. It seems overwhelming to me, but I have been delving into understanding the treasures I am finding. I don't understand all of the classification systems, but I found a place online that seems to indicate that we are in the Mississipian Age? The rocks which have been identified so far are all limestone, so I am assuming this one is limestone as well. The soil is VERY red (someone called it ochre red?) and some of it always remains on the rocks after I clean them. The fossils that have been identified so far are fenestella, bryzoan, crinoid. And I think the word fossiliferous was also used? I am a photographer by trade and macro photography is my FAVORITE, so I will post plenty of photos. This particular rock is a very small one compared to most of them. It is also harder than the other ones I have worked with - less "crumbly". The first couple of photos are of the top and the bottom of the rock, to get a general idea of the size and shape of it. The rest of the images are close ups of various areas. Any and all input is appreciated! Is it common to find an area like this where rocks such as this one are very abundant? From what I can tell these are all common fossils, but a great springboard for learning! Hints on how to clean and store the rocks appreciated, too, since there are so very many of them? Thanks!! Ramona
  9. On my recent trip north, I was fortunate to be able to stop in Wax, Kentucky to look for blastoids. It was very hot and I had only about an hour to look. I didn't find any. But found some other fossils that I am happy to have. All that is left of one brachiapod is barely an outline...looking somewhat like a ponderosa and about the same size. Sorry, I didn't get a scale into any of these. But the nicest part of that fossil are the very typical beekites...sodalite pseudomorphs, I think they are called. They flouresce under black light and are classics. The little oval fossil looks to me all the world like a leaf. Could that even be possible. I know is is not current, because it fell out from the layers of a piece of shale I split at home. I don't know what the formation is at Wax, and would love someone's information about it. And lastly, one of my favorites, just form its shape is something I think belongs to the graptiloid family, though I am not sure. I am looking forward to getting them all cleaned a bit better.

    Archimedes with fronds, in Matrix SITE LOCATION: Chesterian Zone of the Bangor Limestone Formation, northern Alabama. TIME PERIOD: Mississippian Period (ca 350,000,000 yrs old) Data: The Archimedes is also termed moss animal, the Bryozoans are colonial animals that live as filter feeders, filtering nutrition from food through it's fenestrae, a screen-like structure that went around the axis of its screw-like central structure seen here. The Bryzoan Archimedes is named after its resemblance to Archimedes’ screw, a device invented by the famous Greek mathematician, engineer, and inventor to raise water above grade. Specimens in which the mesh remains attached to the central structure are rare. Like other bryozoans, Archimedes forms colonies, and like other fenestrates, the individuals (or zooids) lived on one side of the mesh, and can be recognized for the two rows of equally distanced rimmed pores. Inside the branches, neighbouring individuals were in contact through small canals. Bryozoans are stationary epifaunal suspension feeders. The majority of fossils of this genus are distributed throughout Europe and North America, but they have also been found in sediments of Afghanistan, Canada, Russia, and Australia. Kingdom: Animalia Phylum: Bryozoa Class: Stenolaemata Order: †Fenestrida Family: †Fenestellidae Genus: †Archimedes

    Polypora spinulifera Bryzoan fossil Chesterian Zone of the Bangor Limestone Formation in northern Alabama Mississippian Period c 325,000,000 years ago Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals), are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in a variety of freshwater environments, and a few members of a mostly marine class prefer brackish water. Over 4,000 living species are known. One genus is solitary and the rest are colonial. Kingdom: Animalia Phylum: Bryzoa Class: Stenolaemata Order: Fenestrida Family: Polyporidae Genus: Polypora Species: spinulifera

    Bryzoan - Archimedes screw wrapped in Fronds Chesterian Zone of the Bangor Limestone Formation in northern Alabama Mississippian Period c 325,000,000 years ago Archimedes is a genus of bryozoans belonging to the family Fenestellidae. The first use of the term "Archimedes" in relation to this genus was in 1838. This genus of bryozoans is named Archimedes because of its corkscrew shape, in analogy to the Archimedes' screw, a type of water pump which inspired modern ship propellers. These forms are pretty common as fossils but they have been extinct since the Permian. Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association with the "corkscrews", that are fairly common. Specimens in which the mesh remains attached to the central structure are rare. Like other bryozoans, Archimedes forms colonies, and like other fenestrates, the individuals (or zooids) lived on one side of the mesh, and can be recognized for the two rows of equally distanced rimmed pores.
