Can you ID where a square crinoid columnal fits in it's morphology
Denis Arcand posted a topic in Fossil ID
The crinoid columnals i have found are usually round, pentagonal and star shaped, but today I found one that is square Among a thousand crinoids columnals, this is the only square one I have ever found, why? To which part of the crinoid does it belong to? -
I found this fossile last summer at the beach of Randsfjorden in Norway, Kalvsjøen formation, from late Katian, late Ordovician, but cannot figure out what it is. The speciemen is about 3 cm long and geodized in the middle. Does anyone have an idea what it can be? Thanks for any suggestions. Martin

Fishing for fossils might sound like a strange hobby, but I've discovered that it's the perfect combination of relaxation and excitement. Instead of reeling in fish, I'm reeling in ancient fossils from the Richelieu river. And while I might not have any fish tales to tell, I do have some great stories about my fossil-hunting adventures. It might not be the most conventional hobby, but it's certainly a fun one. And the best part? No fishing license required! The Lorraine Group is known for its abundance of fossils, which provides valuable information about the region's past environments and evolution. The fossils found in the Lorraine Group are mainly marine invertebrates, such as brachiopods, trilobites, bryozoans, crinoids, and gastropods. It is a geologic formation in the Canadian province of Quebec. It is part of the St. Lawrence Platform, which is a large region of sedimentary rocks that underlies much of eastern North America. The erosion of these formations over time creates a variety of rocks with different mineralogical characteristics, which can be found on the beaches in the area. The Lorraine Group is an important source of geological information about the history of the St. Lawrence Platform and the tectonic events that shaped it. These fossils, including crinoid and sowerbyella, offer a glimpse into the rich biodiversity of the area during the Ordovician period, and are estimated to be around 450 million years old. I had spent times meticulously photographing this sowerbyella I had found from the Richelieu river. When I finally found the perfect shot, I snapped the picture with satisfaction. But it wasn't until later, after I had added the picture to The Fossils Forum, that I noticed something small and unexpected in the upper right corner of the image. Upon closer inspection, I realized that two tiny gastropods had photobombed my perfect shot! These little intruders are a fun and quirky addition to the photo, and it gave me a great story to tell. After all, when you're fishing for fossils, you never know what unexpected surprises you might find along the way. I stumbled upon the remains of a previous campfire. As I looked closer, I noticed something white sticking out of the dark ash and debris - it was a coupe of bleached fossils! The colors and patterns of the fossils are truly beautiful, and provide a glimpse into the rich biodiversity of the area during the Ordovician period. I feel fortunate to have found these fossils and to be able to share them with you. I have a funny story to share about the day I took this picture, I was so focused on capturing the perfect shot of a crinoid fossil that I didn't notice the waves getting closer and closer. Suddenly, a wave came splashing on my running shoes, soaking my feet completely! Although it was a bit uncomfortable, I couldn't help but laugh at myself for getting so absorbed in my photography that I didn't even realize I was getting my feet wet. Despite getting my feet wet, I was determined to capture the stunning colors and patterns of these fossils, The diverse composition of the Lorraine Group's formations, with the Nicolet Formation being siliceous and the Pontgravé Formation being carbonate-rich, can explain the variety of rocks found on the beaches in the area. The erosion of these formations over time results in a mix of sediments with different mineralogical characteristics, creating a range of textures and colors in the rocks. These pictures were taken at the beginning of spring, after the winter erosion caused by ice and water waves, which creates a new harvest of fossils that are ready to be collected, with no preparation necessary. I found some really cool fossils! I was crouching down to take pictures of them when I noticed some other people walking by and giving me curious looks. I got a little self-conscious, but I decided to smile and explain to them that I was just taking pictures of the fossils. To my surprise, they seemed interested and even came over to take a closer look with me. We ended up having a nice conversation about the Lorraine Group formation and the abundance of fossils in the area. It was really cool to connect with some strangers over a shared interest, and I'm glad I didn't let my initial self-consciousness stop me from taking a closer look at those fossils! When I take pictures of fossils in bubbling water, it's a really exciting and fun experience. The water creates these amazing patterns and textures around the fossil, making the whole image really dynamic and cool to look at. But it's not always easy! Sometimes the water creates glare or reflections that can be distracting and hard to deal with. And because the water is always moving, it can be tricky to get a good, clear shot of the fossil. Despite the challenges, getting a great photo of a fossil in bubbling water is really rewarding. The water creates a sense of movement and energy around the ancient remains, which makes the photo feel really alive and vibrant. To get the perfect shot, I usually try different camera settings and angles until I find what works best. I'll use a polarizing filter to cut down on glare and improve clarity, and I'll often use a tripod and a slower shutter speed to capture the motion of the water while still keeping the fossil in sharp focus. The fossils that I've discovered are estimated to be around 450 million years old, and have been preserved in amazing detail. It's experiences like these that make me appreciate the beauty and power of nature even more. As someone who combines my passion for photography and fossil collecting, I was delighted to capture the stunning colors and patterns of these fossils. I had been carefully photographing some beautiful crinoid segments that I had found while fishing for fossils in the Richelieu river. I had finally found the perfect angle, when suddenly something appeared in my frame. It was a white feather that had drifted into the shot, obscuring part of my subject. At first, I was frustrated that my perfect shot had been ruined by this unexpected intruder. But then, I took a step back and looked at the composition as a whole. I realized that the feather actually added an interesting element to the photo, creating a sense of movement and adding a touch of whimsy. So instead of deleting the photo or trying to edit out the feather, I decided to keep it in the shot, embracing the unexpected twist that nature had thrown my way. And in the end, the photo was even more appealing and unique because of it. Despite the mishap, I managed to capture some stunning pictures of the fossils, including this sowerbyella, which I'm thrilled to share with you. The abundance of fossils in the Lorraine Group is a testament to the richness of marine life that existed in the region during the Paleozoic era. These fossils have contributed greatly to our understanding of the geological history of eastern North America and continue to be a valuable resource for scientists studying the evolution of life on Earth. To end my day, I couldn't resist capturing theses naturally formed ice sculptures in water , they can be incredibly appealing because they represent a unique and fleeting moment in time. These sculptures are created by the forces of nature, as water and ice interact in complex ways to form stunning and intricate shapes. Each sculpture is completely unique, shaped by the specific conditions of the water and the temperature at the time it was formed. This means that no two sculptures are ever exactly alike, making them a true work of art created by the natural world. Additionally, the way that light interacts with the ice can create a stunning visual effect, with the ice taking on a glittering and iridescent appearance that is truly mesmerizing to behold. Overall, naturally formed ice sculptures in water represent a beautiful and awe-inspiring aspect of the natural world, one that is both visually stunning and endlessly fascinating to explore.

From the album: Fossil Art
These crinoid segments look amazing in their natural color -
What ancient creature is this? it has small bumps, no holes so i don't think it's a bryozoan? I will appreciate if anyone can identify this little fossil for me. Thanks!

I found the following fossils hunting the Nicolet River Formation (Upper Ordovician). The layer where the specimens are is really friable, which makes them really fragile to remove, so I will have to remove a large piece of rock as a support. They measure approximately 2 and 1 inches respectively. I have two questions: 1. What is it ? 2. Is it worth taking it home?

Fall promises to be spectacular in many ways. If you dream of colors, you will like the following. I like fossil hunting in the fall, although it's not really hunting, the fossils are underwater so it's more like fishing. Anyway, this is one of my many trips to this place, it's not very far and it allows me to go for a weekend nature walk. This is Ordovician, the site is not as beautiful or rich in fossils as the other sites we see in this forum, but it is rich in brachiopods, crinoids, bryozoans and gastropods. This time, I chose a theme to showcase my special finds of the day. It's autumn in Quebec, we see all the colors! This year the province offers an extraordinary spectacle. Due to favorable conditions, autumn 2022 is marked by an extraordinary color season. This summer the trees have not been under great stress, which is favorable for an autumn with intense colors, the next few weeks should be just as much. Indeed, the season promises to be particularly hot and sufficiently sunny. According to the expert, clear nights will follow these beautiful days, which favors the coloring of the leaves. Enjoy! For more information about my hunting site, look at my previous post which took place during winter: The day I went fishing for fossils (part I) (winter) The day I went fishing for fossils (part II) (winter) This is my little special place were I go fishing for fossils

I found several kinds of gastropods and two other uknown fossiles in the Kalvsjøen formation, late Ordovivcian at Hadeland in the Oslo field, which I like to share. The limestones in this formation are called 'the Gastropod limestones'. Can anyone please help ID some of these fossils. I guess some of the gastropods cannot be ID-ed, but I hope some of them can be at some level and the other unknown animals. Any help are appreciated. The first rock (the first 3 pictures) has one strange fossile (to the left) and several small gastropods, some very small, which I could only see by taking several pictures from different angles and by using different light sources: Enlarged left side: Picture 3, the right side enlarged: The next, rock no. 2, has a nice shape of the cross-section of a gastropod with 5 levels or spirals: It also has a strange very small fossil, near my finger. Picture 4 Pict. 5 Pic. 6-8, enlaged small fossile: Rock 3, picture 9, another gastropod in cross section, size is about 2 cm broad: Rock 4-5, picture 10-11, two very small and nice gastropods, which I did see only after I enlaged a picture I took of the rock with a microscope:

Hi, I am still new at identifying brachiopods, I know there is a great diversity of similar species, which makes it even more difficult for me. Can you help me identify these two brachiopods, they both feature a semicircular outline, concavo-convex profile, and small size (~1.0 cm wide). They also have a wide, straight hinge numerous and very fine lines and ribs. Not sure if they are the same species, one of them has a larger size with a bit smaller width compared to length. So I don't think they are the same species. The plate was found in the Nicolet River Formation south of Montreal, QC Any help would be appreciated, thanks !
