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

From the album: My collection in progress
Cyrtospirifer verneuilli Murchinson 1840 Location: Barvaux-sur-Ourthe, Wallonia, Belgium Age: 382 - 372 Mya (Frasnian, Upper Devonian) Measurements: 6,6x3,5 cm Kingdom: Animalia Phylum: Brachiopoda Subphylum: Rhynconelliformea Class: Rhynconellata Order: Spiriferida Family: Cyrtospiriferidae -
Hi fellow fossil collector, can you identify this brachiopod for me? I recently found a very different brachiopod, where I usually collect my fossils in an Upper Ordovician formation (Click here to see the site). I can easily find hundreds of swerbyella, but this fossil is very different from what I usually find, its huge size, 3 times larger than any fossil i usually find, and its different shape puzzles me. It measures approximately 3cm x 2.5cm. It also has intriguing concentric protuberances composed of a primary and secondary shell on external shell surface. As you can see it is very fragile, there is a crack going through it which is about to break it in half. Is there a way to consolidate the crack without damaging it further? Thank you!

Ordovician, Nicolet River Formation, Sowerbyella
Denis Arcand posted a gallery image in Member Collections
From the album: Fossil Art
This picture was taken as is, it was not photoshopped, everything is real in the picture. Only the contrast has been adjusted a little bit. I took this picture at a small beach where the fossils are underwater, so I literarily fish for the fossils. You can read my two articles on the subject by clicking on the following links: The day I went fishing for fossils (part I) The day I went fishing for fossils (part II)-

My first post was so popular that I decided to do a second. I went to the same place, and found more many rich and colorful fossils, and got enough material to write to you about it. For those who missed my first post, you will find it HERE As you will see in this article, I combine my two passions, collecting fossils and color photography. I love color, creating black and white photographs of fossils is good for scientific research, when you are a paleontologist and want to record the small details for science and posterity. But for people who are just starting to explore the world of fossils, we need something more inspiring, because to be fair, fossil photos are generally drab, and generally unappealing to the general public. Not that fossil collectors don't take great photos, I see fantastic photos all the time on TFF, but usually in a different context. I'm just trying to be a little different and take a picture of the fossils as I see them, in their natural environment. Maybe this will inspire the next generation of fossils collectors. This site is part of the Lorraine group (Chambly sub-formation). It contains the most recent sedimentary rock in the region, a series of clay and limestone schists that are redder towards the top. It's made up of clay schists, a sedimentary rocks of dynamic origin, formed by the splitting of existing rocks and calcareous schists, a sedimentary rocks formed by the accumulation of animal or plant matter in bodies of water. This region also bears the marks of the Quaternary geological era. Immediately after the last ice age, the whole St. Lawrence Valley and its waterways became a vast inland sea (the Champlain Sea) that stretched as far as today's Lake Champlain. The site is not as gorgeous or rich in fossils as the other sites we see in this forum, but it is rich in brachiopods, crinoids, bryozoans, and a few gastropods. Sorry @Kane no trilobites. Here are some photos to give you an idea of the site, it's a small beach where the fossils are underwater, so I'm literarily fishing for fossils. The formation is made up of many colorful stairs and steps leading to the water's edge. Like a time machine, each step takes you back a thousand years, where you can discover at each staircase the remains of a thriving fauna, long extinct. Don't expect to see anything bigger than a few inches, this is the Late Ordovician historically rock formation in the Richelieu River Valley in the St. Lawrence Lowlands rests on sedimentary rocks. which are some 450 million years old and formed during the Cambrian Period of the Paleozoic Era. I was able to photograph this hash plate full of sowerbyella at that special moment, when the water was receding after a previous wave. This is not a painting, just a photograph of what typical Ordovician fauna might have looked like 500 million years ago, almost as if we were there. I try to keep my hand dry and out of the freezing water, picking up the fossils between two waves, leaving the fossils out of the water. It was difficult to photograph the fossils underwater, because of the waves I took the photo at a time when the water was calmer and just before a wave came crashing on it. A lonely sowerbyella taking her beauty bath I found bi_valve playing hide and seek, with the bubbles A lot of times I hear that fossil and water aren't a good mix, but in my case it's a perfect match. The water acts as a sort of magical act, bringing these 450 million year old fossils back to life, infusing them with vibrant colors and hiding the passage of time. These normally terness fossils have a second life in this freezing water, small imperfections are hidden, making the texture smooth and lustrous, with beautiful vibrant colors. In homage of the Beatles, I call this one the Yellow Submarine Some brachiopod pile up over each other, I don't know what cause this rainbow of colors, the diffraction, the translucidities' of the fossils. Whatever the reason, it's a beautiful effect and a total surprise. A colorful brachiopod on a colorful rock I really like the contrast of theses two plate Don't need to search, no fossil here. Just a color full formation. Crinoid columnals are the most commonly recognized crinoid fossils, they are individual pieces of the column, or stalk, these resemble small washers. Olympic logos gone wild or Crinoid columnals, you choses. I particularly like the circles with a small star inside Columnals are joined together in life by elastic ligaments and skin. However, when the animal dies these soft tissues quickly decay and the stem break apart into individual ossicles, they leave behind a great many fossils. After the crashing waves, they sometimes cover themselves with air bubbles, giving this strange old world a new dimension. The hole in the center of the columnal is called the axial canal. It is most commonly round but may also be pentagonal or star-shaped, like this 1 millimeter fossil. Despite their small size some fossils can still be the star of the show. Bryozoans consist of a skeletal structure of calcium carbonate that has numerous tiny holes or openings dotting the surface. These holes once housed individual bryozoan animals called zooids, that derived their nutrients from the seawater. Atlas Of Ancient Life I found this briozoma all alone on this big boulder, strangely it comes out of the rock and comes back in right away. This is another bryozoan, it was on a smaller rock and I was able to collect it for my collection Most colonies were only a few inches in diameter but a colony of an Ordovician form found in the Cincinnati region ( Florence, Kentucky) is more than 26 inches in diameter and is one of the largest known bryozoan colonies. I really like this formation for it's richness of colors Photo taken in direct sunlight of a wet bi-valve Again, mother nature was playing with ice producing these wonderful sculptures everywhere we look. It was such a nice day, I couldn't resist taking some in picture. See other Ice sculpture Here. Crinoid columnals trapped under translucent ice. I found all theses fossils in just haft a day at that very special place. For those of you that did not see my previous post about my first fossil fishing trip, your in luck because it is still available HERE.

Dive Into an Ordovician Ocean—Trilobites—And a Rare Find
FossilSniper posted a topic in Fossil Hunting Trips
On July 1st, 2021, I went for the first time to a public, personal site and was very pleased with the results of my fossil excursion. The locale consists of several exposed formations, namely the Liberty formation I was hunting in. In my region of southwestern Ohio, that's known to be one of the best fossil-hunting formations due to its remarkable preservation of particularly fragile Ordovician life, even when compared to the excellent fossil preservation quality of other formations in the area. The thirty-three degrees Celsius heat was rather hot by itself, and as the sun's rays made me question my latitude, the rainwater in the ground from the rain several hours prior was evaporating and creating a blanket of humidity-saturated air which prevented my body from transpiring. That was lovely. On top of that, this was above a very tall cutaway, so there was this constant updraft of hot, humid air coming from the bottom. Needless to say, conditions were extremely hot and humid. A thermos filled to the brim with refreshing, ice-cold cranberry-grape juice was a lifesaver, as otherwise I would have certainly overheated and becoming a sizzling omelet atop a frying pan of Ordovician fossils under that laser of a sun! With that being said, this is my first post regarding a fossil hunting trip in three years! While I have not been active on this forum, my paleontological trips have been ever more numerous. I remember you all, as I have been secretly watching in the meantime. I am a fossil sniper, after all. I should mention that I am an adult now, and I would prefer to have the "Youth Member" tag removed from my name. I plan to conduct a full survey of my entire collection before attending university, so look out for that. My collection is considerably sizeable now, having nine years of fossil-hunting under my belt. Here are my finds! Best & rarest for last, though all of them are incredible in their own right. Every edge of a square on the grid is half a centimeter. Assorted rugose corals. Gastropods. Branching bryozoan. The central branching bryozoan specimen in the prior figure under 200x microscope magnification. The skeletal cavity wherein individual zooids once resided 440 million years ago are evident, each 0.2 millimeters in diameter. The sheer level of detail in the preservation is as mind-blowing as this fossil's age. This photo is the product of using a computer to compile 140 photos focused at different layers of the specimen, as microscopes have a very narrow depth of field. I'm sure you all find as this fascinating as I do, so I compiled a photo for you guys. Assorted brachiopods, with two bivalves on the top left. I collected some superb Rafinesquina alternata, which don't tend to come with both fragile and thin halves intact, together, and out of the matrix. There were also some Leptaena that I did not photograph, but were lovely and undulating. The rest are common genera here, except for the fourth one from the right in the bottom row and the partial one of the same species immediately northwest of it, which I would like help identifying. Expect to see it soon on the ID forum. Assorted associated, straight-shelled nautiloid cephalopod septa. A larger example of associated, straight-shelled nautiloid cephalopod septa and a partial living chamber. Calcified straight-shelled nautiloid cephalopod. I always love the crystals on these. Flexicalymene meeki on the left and right. The left one is perfect, and is a very large example of what I generally find--my largest self-found complete trilobite, in fact--so I'm very happy with him. The right one is heavily weathered along its left and right, but the medial length of the pygidium, thorax, and cephalon are all present in some way, and the pleurae and glabella are resonant with Flexicalymene meeki, and I'm very happy with him, too. Adorable, curled little finger hugnuzzles of the ancient sea. Drum roll please! Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 This is a huge living chamber of a straight-shelled nautiloid cephalopod! Unlike the septal segments, the living chamber is very fragile with its thin, unsupported walls. This means it is very rarely preserved. Hence, in my near-decade of fossil hunting, I have never found a complete living chamber with its outer shell included until now. Let alone of this size! The only reason this one survived is because of the encrusting bryozoan that grew over its walls and thus strengthened them after the animal died--Figure 5 demonstrates the layers of the bryozoan well. This is also demonstrated on the side without bryozoan strengthening it in Figure 4, and how it simply crumpled due to the weight of sediments that accumulated on top of it after the animal died. Interestingly, one side has much more encrusting bryozoan than the other--this suggests that immediately after the animal died, part of the shell was resting on the silt of the ocean floor, preventing bryozoan from growing on it. The contrast in the thickness of walls of the living chamber & encrusting bryozoan growth on opposite sides of the fossil is evident between Figures 1 and 2, where in Figure 1 the walls of the living chamber are quite thin (one can tell from the thickness of the dark cracks on the bottom left), whereas in Figure 2 the walls are visibly significantly thicker (and layered from the encrusting bryozoan, upon zooming in). Deducing all of this is so cool. Additionally, Figure 3 zooms in on the bottom left fraction of the visible living chamber in Figure 2, and it actually shows the bryozoan growing around the edge of the living chamber walls and into the living chamber. This means that's the very outer rim of the living chamber! (In Figure 3, the white line is the living chamber wall, and the layers around it are the encrusting bryozoan. The light tan stone inside is just limestone.) On top of the sheer rarity of a fossilized living chamber, especially of this enormous size, having the edge of the living chamber preserved with enough detail to show the bryozoan that that grew into it over its rim—almost half a billion years ago—fascinates me. To finish this post off, there really is a mystery in every fossil. With the encrusting bryozoan only growing one side of the living chamber in the final specimen, and the subtle, hard-to-spot detail of how it grew around the rim and into the living chamber, it's like every fossil is a murder mystery (literally) and we have to be Sherlock Holmes and figure out details about how the animal died. Considering this was 440 million years ago, we're all some pretty hardcore forensic scientists!

My collection of some really cool fossils on the land most of the fossils I have in my collection are bought so it’s always nice to find something actually in the field. Now my main goal with this post is to try to identify the trilobite I found today although it only has the head piece, it clearly shows the eye and part of the gabella. The horn coral which are the sort of conical fossils should help identify the age of the rocks. if anyone else can give an ID on the rest of the fossils that would help thanks. By the way these were all found in Dane County, Wisconsin. (PS) I have no clue what the fossil is with the weird holes.

I've had some difficulty narrowing down the identity on some assorted brachiopods. The diagnostic features may not be preserved but I figured I'd post them here to see if anyone knew. @Tidgy's Dad Any ideas? The first is a single large valve from the Warsaw Formation in Fenton, Missouri (The old Meramec Bridge site). I've been able to track down most species reported from here and identify everything else but this one is harder. The wear doesn't help. The second are a couple o Echinoconchidae valve casts in chert from a creek in Lincoln County, Missouri. It could be residual chert. The area is otherwise Ordovician. 2.8 cm width x 2.5 cm height. 3.8 cm x 3.2 cm

Request for feedback on fossil field guide visual layout
pefty posted a topic in Questions & Answers
I'm working up a series of fossil field guides for various formations. I'd like to provide a visual indicator of which fossils are rare, which are common, and which are abundant, without getting in the way of the visual layout of the fossils & identifying information. The complete set of categories I am working with is {Abundant, Common, Rare, Very Rare, Common to Abundant, Rare to Abundant, Rare to Common, Present, and Questionable}. Has anyone seen a good way that a field guide of any kind has provided such a visual indicator as a page-wide element of visual layout? Attached is my first draft for the brachiopods of the Zaleski Flint Member of the Allegheny Formation (Pennsylvanian) of Ohio. All feedback welcome! Thanks.

I found this beauty yesterday in a gravel in central Poland, so it's an ice age gift from Baltic Sea or Scandinavia, Ordovician or Silurian in age. Any ideas? I'm thinking... maybe a billingsellid of some sort? I'm not good at Palaeozoic brachiopods.

Paleo Society access to Treatise on Invert Paleo
Wendell Ricketts posted a topic in Questions & Answers
Though I have a feeling I'm going to be embarrassed for asking what turns out to be obvious, but: I was hoping someone would be willing to give me a hand getting access to the 2007 Suppl. to Part H (Brachiopoda), Vol. 6 of the Treatise. The archives only appear to go back to 2010. Do Paleontological Society members not have access to earlier volumes? Thanks! Wendell -
Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA

I found this apparently silicified pedicle valve as an erratic boulder. The age is unknown, but presumably Ordovician or Silurian. Provenance of Baltica (found in Poland, but in gravel parking lot). Any clues on the order? The rest of the shell is hardly preserved. Can you help to verify my anatomical identifications?
