    Cephalopod Shell Color!

    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!

    Coalified wood?

    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!

    Beekitized stromatoporoid sponge?

    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

    Devonian worm burrows or organ pipe coral?

    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!
  5. SilurianSalamander

    What could this possibly be?!

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

    Sowerbyella, Nicolet River Formation

    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

    Marine Paleozoic Invertebrate Fossil

    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.
  8. 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.
  9. 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:)
  10. 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/
  11. 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.
  12. 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.

    Paleozoic Bivalve or sponge?

    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!
  14. 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.

    Help please! Unknown Paleozoic fossils.

    3 and 4 were found in the Devonian milwaukee formation.

    Nautiloid or crinoid?

    Found in a culvert outside of fast food place. Paleozoic limestone of unknown age. Help!

    Mazon Creek "Cone"

    Maybe 6-7 years ago, I was at a local gem/mineral show. There was really just one dealer with a variety of fossils. it was a mix of what was left of a family collection that he had bought plus other stuff he picked up. He had lowered the price on whatever hadn't sold at the previous show. He had several Mazon Creek specimens - mostly small "ferns" in nodules plus a weird arthropod-looking thing. I had hardly any Mazon Creek stuff other than what I think is a Paleoxyris so I asked him what he would take for the group. It was super-cheap so I bought the pile. I thought it was cool that I got both halves as it makes it a more interesting display piece. The nodule is about 2 1/2 inches (58mm) long It was labelled simply as "Will County, IL cone" so I was left to assume it's a Mazon Creek piece just out of what it looks like. is it a cone? If so, what plant?. If not, what is it? I have an older reference for the plants of the deposit, "Guide to Pennsylvanian Fossil Plants of Illinois" by james R. Jennings but it's buried in a box somewhere and may be outdated. I'll still try to dig that out just to see what it says. I request the opinions of the "Mazon Creek regulars," the names I see pop up when the subject of the fauna and flora comes up, plus anyone else with an interest. @RCFossils @Nimravis, @deutscheben, @connorp Thanks, Jess
  18. I did lots of online searching on which states trilobites have and haven't been found in, and compiled this. Its not as straight forward as you might think. Green means trilobites have been found in that state on the surface and are native to that area. Yellow means technically a trilobite has been found there but was found below the surface or the rocks are not native to the state. Red means no trilobite has ever been found in the state except for when humans have transported them there. Green: Alaska, Alabama, Alaska, Arizona, Arkansas, California, Colorado, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming Yellow: Florida, Louisiana, North Dakota Red: Connecticut, Delaware, Hawaii. No trilobites have been found in these states. The only trilobites in Florida and North Dakota came from cores that came from very far below the surface. Louisiana has trilobites from gravel that were transported via rivers from the Tennessee region. I have found very little references on trilobites coming from Oregon and Mississippi but have heard they exist. As far as Washington DC goes, I haven't seen anything that has said a trilobite has been found there but there are Paleozoic rocks at the surface according to macrostrat and trilobites have been found not too far away so I left it grey. Does anyone see anything incorrect with the above information? Before I undertook this task I knew trilobites were widespread but not this widespread. Trilobites are everywhere. I thought I'd share with the group.

    More Paleozoic finds

    The 1st few may be the strangest rocks I have found. Appreciate any input. Thanks! Rock 5Rock 6 & 7: could these be fossilized tree roots?Rock 7 - external surface Rock 7 - close up of internal side (smooth) side Are the following specimens too weather worn to make a general ID? I know they are pebble-ish, but on some, there are potentially ribs (very worn), etc. I’m wondering about echinoids, ostracods, possible small brachiopods. Potential bivalve?
  20. SilurianSalamander

    Giant Ostracod?

    Found in some Paleozoic chalk and limestone gravel along with crinoids and brachiopods.

    Asterosoma?

    Found in Crane Hill, AL (Carboniferous) Could the (presumed) burrows be part of an Asterosoma sp? Thanks for looking
