I saw this potential fossil in the Jurassic age Navajo Sandstone in Zion National Park in Utah. I'm sorry that there is only one picture with no scale. I was hurrying down the precarious Angel's Landing trail with a long line of people behind me, so I only had time for a quick picture. The feature is probably about ~12 inches long, and I believe that it is situated on the plane of a cross-bed in a dune structure (example of the cross-bedded sandstone is also pictured). This feature might just be some sort of iron precipitation, but it looked so similar to an invertebrate trace fossil that I am

Loose on the cobble at Blue Beach, Nova Scotia. I believe this is a trace fossil. Just wondering if anyone can recommend some resources on how to interpret trace fossils? Thanks for your help with this.

A little over a month ago my dad and I checked out two exposure of the Mifflintown Formation (Late Silurian) in Western PA. While the sites are known mostly for their brachiopods, we ended up finding a couple of other fossils, including several Favosites niaragensis, Hormotoma, and some trace fossils. While I would normally leave the trace fossils alone, I was really awed by the size and appearance of the burrows. I love the bumpiness of the burrows and randomness of their direction. They are almost a work of art. So I decided to take one home. I am not very good at identifying trace fossils t

Found this on my last trip to the quarry just northeast of Rockwood. Barring an unexpected snow melt it will be the last for the season at least. It's thought (by me) to represent a marine delta environment. The quarry is likely to be in the Tomhegan formation. Seeing the photos makes me think the shapes are probably all trace fossils. But what would explain all the variation ?

Found this piece on a walk near a Triassic outcrop in Pennsylvania, has a pretty exact visual similiarity to the wing rib of a Triassic reptile but is likely just some form of sedimentary trace. It would be great to get some more opinions on this piece to see if its worth holding onto or I would label it to be definitely sedimentary and rid of it, which I feel is the case.

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.

A selection of Permian trace fossils
FF7_Yuffie posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, a bunch of Permian trace fossils that I am interested in buying as a bulk order. Before I can confirm, if anyone could take a peek and let me know that they seem ok, that would be great. All from French locations--but correct spelling may have been jumbled in autotranslate. I'm planning to buy the lot, but if anyone spots anything amiss, if you could let me know, that would be great. They do resemble other similar fossils I've seen for sale online. 1 - Dromopus lacertoides -- Lodeve France 2 - Anthichnium salamandroides - Lodeve France 3 -
Hi, what's the thought on these? Highlighted, as common. But seller says it comes off easy and kncluded some non highlighted pics too. From Connecticut River Valley.

After reviewing some of the identified fossils on this site, I think I may have a trace fossil..? But on the opposite side if this rock is another impression of a round “shell.” This was found in Southern Colorado. Any idea what the small shell-shape is in my second photo?

New to geology, so excuse my paltry terminology. Description: Tubes, many branching, between 1-3cm in diameter, in places as thick as a forest root system, material very sandstone-y, surrounding material clay. from my research these seem like burrow casts of... worms? tetrapods? do burrow casts form in such abundance?

Found this on my phone from two years ago not sure what i am supposed to be looking at? Threw water on it for some reason. Whole rock is about a foot long.

Hey guys, I got a couple of fossils I am struggling to ID. All fossils shown were found in Fallen Timber creek, Ab, Canada. They were found along a rock bed along the creek itself. The first set of pics is a rather common fossil I find, with it being a imprint of some kind on a black rock. Was wondering if somebody could ID the actually imprint itself as I am having trouble doing so (think it is some kind of coral or other "aquatic vegetation"). The next set is a bone shaped object, looks to be the end of a joint. But I am unsure if it is just fracturing in

Found on blackstone river NWT Canada. Not sure what formation it is but its either devonian or cretaceous nothing between. My best guess is Fort Simpson formation so late devonian.

NEED HELP!!! Is This Just an Iron Concretion or A Preserved Fossil?
Kurufossils posted a topic in Fossil ID
Hello everyone, I am in desperate need of help with a huge debate I have been having with a friend over fossils preserved in ironstone concretions. From some of what I had read to some advice from other members I it possible to find vertebrate bone among shells and other mollusks preserved in an ironstone concretion. Whether it leaves a trace of the organism, morphs the organic material into the structure of the iron concretion through the decomposition with preserving, or whatever else it may be it seems to be possible. So recently I have hunted a place known to have recorded mar -
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.

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

Figured I’d post one more while I’ve got the collection out. When I was younger, my grandfather had a gravel driveway put in. I assume it came from Ohio, although I have no idea in truth. I frequently picked through it and found a few fossils. The gravel is clearly made of marine sediment for the most part - I’ve found brachiopods, trilobite fragments, shells, etc. I just wonder what these two could be? The first one has a couple of different structures in it - I’m thinking sponge or coral for the main part. The second, I have no idea. It looks footprint-ish, but this

I found this near the 476 turnpike where they tore up all the ground and exposed the New Brunswick Formation. This formation is triassic. I went to a dump site where the construction company took all the rock. Is this possibly some sort of trace fossil from a lizard or sphenodontid? (If you neer to see it better flip your phone or device upside down)

This is another piece from the Platteville formation in Beloit Wisconsin. Inside a gastropod shell there is a hexagonal pattern that sort of looks likes Paleodictyon, but I think this fossil formed in too shallow of water for Paleodictyon to occur, but I am not sure. Its on a 3" post-it note for scale. (There is also a nice Pterotheca to the left!)

Short visit (1-2 hours) to famous locality near Las Vegas. I wish we would do better home work because some interesting trace fossils were identified only after we watched the video recordings. Perhaps, our "movie" will help you not to miss them when you will visit this unique place. It was a family Christmas trip, by the way. Also, if you know the species, please help with ID.

Do these appear to be trace fossils? Found in Western Colorado. Thank you

I found this on the foreshore at Penarth beach (rocky) close to cliffs. I assumed it could be a trace fossil of some kind? Somebody on Reddit suggested perhaps Fusulinids, and they certainly resemble those from what I’ve seen, but it doesn’t look to tie in with the age of the rocks at the site.

Okay so I found this specimen at the Taughannock Falls in Ithaca New York. I found it at the edge of the gorge which consists of Shale, composed of slit and clay that fell onto lime mud and hardened into rock. I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor. Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and w
