Earlier this year I was fortunate enough to meet up with @digit in Gainesville Florida where he very graciously provided my wife and I the opportunity to do some matrix fossil hunting in a local stream. We sieved for a good long time collecting many nice shark and ray teeth as well as other items out of the large portion. At the end we nearly filled a five gallon bucket with gravel that we ran through essentially window screen in the creek to get out the silt and clay. My original trip report can be found here: http://www.thefossilforum.com/index.php?/topic/114209-north-florida-

While I am out in the badlands of the San Juan Basin, I keep an eye out for the trace fossil known as Asthenopodichnium...lozenge shaped overlapping pouches or cavities found in petrified wood. My first encounter with it was a number of years ago in an outcrop of Upper Cretaceous Menefee Formation. I threw a chunk of wood, with this very interesting texture, in my bag and took it home. Perplexed by what it might be, I showed it to Spencer Lucas at the New Mexico Museum of Natural History. He was happy to see this specimen and we discussed the theories of what it might represent, as it is not f

Hello everyone! ive got three slabs of prints created by an unknown prehistoric animal (if it’s even created by an animal) that had been in my collection for quite some time now. Since I’m on the forum and still requires a proper identification for it any identification help from ichnofossil experts are much appreciated! Here are some pictures of the fossils but since the prints might not be that clearly seen I uploaded some other pictures highlighting the “lumps” or the pattern made by the print. Hope that helps.

Hello all, Here are a few Diplichnites incertipies specimens that I found on a 2019 expedition in Nova Scotia. It is illegal to collect fossils in NS without a permit, however all the fossils found at this site (see large arthropluera tracks and tetrapod footprints in prior posts) have been brought to the local museums attention. Stay tuned for more! I hope you enjoy, FossilsNS

A giant undersea sand worm’s fossilized lair by Eleanor Imster, EARTH, EarthSkyOrg, January 28, 2021 In 20-million-year-old rock off the coast of Taiwan, researchers have discovered what they think is the fossilized burrow of a giant, predatory sand worm. https://earthsky.org/earth/scientists-find-evidence-of-giant-predatory-sand-worms the open access paper is; Pan, YY., Nara, M., Löwemark, L. et al.

Hi all So I took some pictures of some very interesting trace fossils. They are found in the upper Devonian, frasnian, Witteberg group, Swartruggens formation. Is it possible to get an identification on these?

Hi all! I found a rock that commanded my attention while goofing off at a friend's house along the TN River. I thought I saw trace fossil like marks on the large rocks we were crawling on but they were very worn. Then I spied a much smaller piece, covered in algae and plant matter, that had very pronounced markings like I was seeing on the large rocks but also some broken lines that were very curious. The markings extend down the side of the broken rock and there are some deep "dotted" lines that are at near 90 degree angles as well as some shallow "dotted" lines that follow the natural curve

Took me a little while to post this trip report, I'm always a busy person. This trip is from October 3rd, 2020 in Ellsworth County, Kansas at a reservoir. The predominant formation at the site I visited is Kiowa formation; which is known for marsh and delta environments in the early Cretaceous (Albian). I found some interesting things and I'll show below. Possibly some carbonized wood materials. Lignite or coal? It was flaky and would crumble if touched. It left some black powders on my hands after handling it. I found several large pieces of them together and partly encased in con

I have these fossils here from the early Jurassic, Northamptonshire. I was wondering if the one on the left could possibly be a coprolite, or some other fossil, although most likely not. It does stick to the tounge. I also have these bumps on bits of rock, and was wondering if they could possibly be due to bivalves? And lastly, a slightly curved thing that has equal thickness which I have no clue what it is. Many thanks

Hey all. Found this sort of trace fossil I'm assuming, in some shale shelves. My initial thought was Gryphaea but it lacks the proper lines and structure to be a shell. Now I'm leaning towards Zoophycos. Can anyone confirm if it is zoophycos, and help with the morphology of this specific find? I'm under the impression that zoophycos morphology changed throughout the ages, and I'm trying to reverse ID the age of rocks I found it in since the geological maps of my area are extremely vague and lack detail. Let me know if more angles are required for this ID.

I recently moved into a house with some friends on our university campus, and this nice cabinet was included right past the front door. So of course I had to put together a little museum! These are just the fossils I have on me at this time, but I’ll probably pick some more up to add next time I visit home or if I go on a hunt soon. I tried adding some fun blurbs with a couple that I felt had some really cool information hiding in them. If there’s any specific part you want to see, or if you have any fun suggestions, let me know!

Thought I would share some of my Acrocanthosaurus tracks in my collection from Texas. These are from the Glen Rose Formation. Anyone who has dino tracks, please feel free to post them here on this thread too...would love to see them! The associated pair are big...both over 20 inches long.

Hey everyone just wanted to check in with you all and see how you are doing. I also wanted to inquire about these Worm Borings/Concretions, and what our members consensus might be. Maybe our resident concretion collector @Ruger9a would be able to help me out. Anyway, here are the pictures: Here is a photo of the excavation site:

Found in the southern Adirondacks.. Northeastern Lake George. At about 600-700 feet above sea level. The stone itself measures about 12x14 cm.

Hi, newer member and fossil newbie, went on one of my first fossil hunting trips recently at a locality I learned about in part from this forum, so thanks. Found a piece of stone with (what I'm 90% sure is) most of a trilobite on the left, but the stone also had a rounded streak through the middle. Does anyone know if this some form of trace fossil, or just awkward shaping of the stone? The piece is from the middle Devonian and Needmore formation of West Virginia, and the streak is roughly four centimeters long.

I stopped by a new road cut today to see if it would be a viable hunting spot. One of the things I found there was this interesting piece. Maybe an Ichnofossil? Some type of burrow or feeding trails? According to the USGS map, the cut is Salem Limestone which is Upper Mississippian in age. Any ideas? This small piece that I picked up came from a larger slab that was over a meter wide. The whole rock was covered in these and they are in between the layers. The big ones are only about 1cm across and most are half that. A photo from the field... This is

I'm rather embarrassed but i need some ID help on something I purchased a few years ago. My chagrin is because I usually am very good at labeling purchases or at least taking a pic of a label if the seller does not provide one. I have this piece of shale that has some fossil claw or fin marks on it that I recall are swimming traces. The shale comes from the Triassic or Jurassic of the Newark Supergroup in Pennsylvania. Any help is appreciated!

Whenever I bring home a new batch of fossils, I pull out my UV rock lamp. Why? Some fossils glow in the dark, but not in a uniform way. Variations in the mineral composition make for a variety of colors, even when the specimen seems fairly uniform in color in daylight. This can make small, hidden details really stand out. Case in point: This afternoon I was putting away some petrified wood I'd collected awhile back. I pulled out my black light to examine them because some of the wood from this site shows a rainbow of color under UV. This one particular piece was mostly orange under

Hi Is this ichnofossil? I found a specimen under an overturned tree so I don't know what time it is. This trace is on both sides in the same place.

I think I am interpreting this correctly. Seems that this 2 B yo track is being interpreted as a slime mold trace on a paleosoil. https://m.phys.org/news/2019-10-ancient-fossils-reveal-fresh-clues.html

Zoophycos are swirling patterns in silt stone that may cover acres of flat ground. These trace fossils occur on the sea floor from the Ordovician to present, but no specific animal has been definitively identified. It is believed that they are created by movement and feeding patterns of polychaete worms.
