Good evening to everyone who comes to see my post, I thank you in advance for the time you take to read the question you presented, which would be the first of several specimens that I have not been able to identify. About two years ago I started hunting for fossils almost by luck as I was looking for minerals until I found the first turritellas, on one of these trips I find a rock of considerable size and weight with a curved linear pattern similar to "worms" although I honestly don't really know what it is, I have found trace fossils but never horizontal, and less than that thick, I have found specimens of what could be crinoids (or belenmites because of their shape) and a lot of unidentified things due to the large conglomerate in which they are found, what I have been able to identify are trilobite tails and spikes (perhaps), all this separately, never a complete specimen in a type of black rock with a slight percentage of pyrite, a stone very different from the "worm" specimen, which is more of the sedimentary type - quartzite when sectioning this stone to see if other specimens were found in any other layer of this stone I have only counted 2 or 3 oysters of about a centimeter. I found the rock in a river where apparently there is an exposed rocky stratum and in the seasons of crescents they go down with the torrential river. I have found other stones with total conglomerate of oysters others assorted with trilobite tails and oysters and shiny clams, and the aforementioned type of black rock beautifully preserved i have never found a complete trilobite specimen (if this helps in identification) the rocks come down from one area called "eastern mountain range" in Jujuy, Argentina, where several things related to trilobites and a species were discovered (connoisseurs will recognize Jujuyaspis keideli Kobayashi (1936). For the rest, I cannot provide more information since I do not know the real location where this rock came from. I attach the images of the specimen. The rock measures more than 40 centimeters and weighs something around 2 or 3 kilograms. All the best. Thank you!

Hello all! Recently I have been obsessed with cephalopods and realized there is a real lack of reconstructions of the color patterns on extinct nautiloids and ammonites! This led me to compile a list of known fossil color patterns on cephalopods. After a year of on and off research, I found about 90 species of cephalopods retaining official or undescribed, original patterning on their shells. These are the first 15 species on my list. The color markings are based both on descriptions and photographs of the fossil material. The shades of the markings are based on the fossils, but also inferred. I Hope you will appreciate my work!

Found this larger chunk of rock (too hard to be modern charcoal) while sifting for microfossils. It has a metallic look to it and is fairly brittle. It was found on bradford beach on Lake Michigan and was likely eroded out of the mid Devonian Milwaukee formation which is known for its coalified trees and giant fungi. this looks like a lot of coalified wood I’ve seen pictures of, but I’m pretty new when it comes to plant fossils so this might just be mineral. Thanks!

Found at work among crinoid, brachiopods, silicified corals as well as a possible cephalopod and some silicified stromatoporoids. Silurian SW Wisconsin. Looks kind of like a cartoon bone in shape

Found two of these fossils now. Both on beaches that are probably Devonian in age. One is from SW Wisconsin on Lake Michigan and the other is in the Lower peninsula of Michigan from the shores of Lake Huron. Organ pipe coral or some sort of burrow trace fossil? Thanks!

Found on a Devonian beach on Lake Huron in port Huron. Thanks!

Location shows huge die-off of Sowerbyella sericea and other brachiopods in smaller numbers. The specific layer could not be determined as it was discovered at ground level on the beach. Loose as float,. The following reference has been used to aid in identification Geologie des Region de Saint-Jean (parti nord) et de Beloeil (1985) Gouvernement du Quebec - Ministere de l'energie et des Ressources Direction General de l'Exploration geologique et minerale Geologie des Region de Saint-Jean (parti nord) et de Beloeil

Can anyone identify this Paleozoic marine invertebrate fossil in my collection? I know some of you might say the whole rock is a piece of fossilized coral but I don't think the entire rock is a fossil. I believe the pores might be invertebrate burrows but I'm not certain. I purchased it at a fossil convention so the context is lost.

Anyone know anything about Californian Helicoprion fossils? I know they’ve been found in Eastern California, but that’s about it and I’d like to learn more.

Can anyone help me narrow down these maybe gastropods?

Crane Hill, AL Carboniferous Thoughts about this textured layer of this rock? A few weeks ago, I realized this specimen was too fragile to be cleaned by a newbie. The surface looks sort of like pebbled leather, but it is extremely brittle. I put it in a box to explore later when I have learned how to clean something like this. Tonight, I came across a pic of megaloolithus in old thread about Dino eggs emphasizing texture. I realize my specimen is is not from the correct time period to be an egg shell of anything - but, it piqued my curiosity again. Dino Egg thread Any thoughts? My inexperienced wild guesses: arthropod carapace? Under surface of exoskeleton? I hope the texture comes across in the photos. Thanks for looking:)

Hopefully I'm not breaking any rules here posting a link. I spent my weekend finally putting my catalog into a proper database, and creating a user interface for it. I used to use Google Sheets, which is pretty great. If I wanted to, I could use them as the source of data, but I decided to create a proper MYSQL database so I can keep relationships across tables, such as the stratigraphy of particular find locations. I have many more improvements coming for it, but it is at least functional right now. Everything from CG-0001 to CG-0161 is from the Glenshaw Formation, Conemaugh Group. https://fossil.15656.com/catalog/ I also maintain a thread with individual photos here, just not everything: https://www.thefossilforum.com/index.php?/topic/94495-pennsylvanian-fossils-from-the-glenshaw-formation/- 6 replies

Stromatoporids, other sponges, or not a fossil? Thanks!

All collected in gravel and beach rocks from SW Wisconsin. Thanks so much for the help! I love this community:)

I found these back in January but apparently never posted them here (can't find any thread), I'm post mostly to my FB nowadays. I found these in about 30 minutes. They are typically assigned as "Petrodus" but who really knows. Years ago at this site I found teeth from at least 3 shark species including "Edestus". These are from the "Mingus Formation" I believe.

Vestavia Hills, AL (Ordovician to Mississippian) I found these very odd rocks exposed by recent flooding. i wondered about a tree root mold or burrow for the first one, but figured low chance of identifying. Just in case, I did a vinegar soak to remove more of the mud. Today, I saw a tiny little spiral shell. Is it a fossil? (vs a modern snail that got trapped in this sediment). Any thoughts about the overall shape of the rock? Since it was found nearby, I’m including a pic of the other weird rock. I considered part of a horseshoe crab or trilobite molt, but I can think of more arguments against than for these. Thanks for looking.

Despite weathering, I was hoping there may be enough features for an ID. My initial impression was that it could potentially be a bivalve. However, after seeing a photo of fossil sponges from the area (see last pic), I think that is a reasonable consideration as well. Thanks for looking!

Pottsville Formation, Alabama I would like to peek under the mud on the specimen in the first pic to determine if it is a compression fossil. This film on this particular sample seems brittle so I have to be careful. I can see pigmentation under some of the mud - that is where I want to work. Ideas? I hope I’m using these terms (carbon film, compression fossil) properly. I included other pics of other specimens that have carbon film or some type of mineral imprint (not sure what the term for this is) that I am to cleaning, sorting and comparing to potential compression fossils from Carboniferous. I was initially ignoring the specimens that look like pattern could be iron staining- thinking all were Liesegang rings, but I’m not sure that explains all of them.
