Hoping someone easily recognizes these and its an easy answer...my initial searches have been fruitless... So I was supposed to be looking for more Florida coprolites in the garage piles of fossils and got sidetracked looking as this large Turbinella columella and just noticed these tan circular markings on it and wanted to know if they were traces of serpulids? Probably Pliocene Tamiami formation, Sarasota County, Florida. Whats fascinating to me is their spiral?/concentric, ornamented/segmented? shape which appears to actually be etched into the gastropod shell itself. Almost look like cross sections of forams. I've scraped a number of the small white serpulid tubes off thinking I'd see a similar pattern but there is no marking beneath them--its perfectly smooth. If it is a tube, I wasnt aware that they could actually score the surface of the gastropod shell--seems pretty neat if thats what going on but maybe its something entirely different. The gastropod, aside from being badly damaged has sponge borings, barnacle and coral encrustration, and serpulid tubes. Most of the circular traces are around 1mm in diameter and a few push the 2 or 3mm size. Thanks for the help! Regards, Chris

Everyone, Any help appreciated. It has been cast and is being referred to others as well. This is a large shale slab fro the Devonian which appears to have been flipped over from stream bottom during a heavy flood event. So this is most likely a positive of an actual negative trace. i.e. a perfect squiggly "groove" 3 feet long. Marc

If this is a trace fossil, does it have a scientific name?
corporateidentity posted a topic in Fossil ID
Hello everyone! I found this specimen also in a creek on a walk through a local park north of Pittsburgh. Thinking it may be a burrow fossil, but if it is, was wondering if there is an actual scientific name for it, so I know how to file it away accordingly under the proper name. Found the term Cruziana online, and wondering if this would qualify. Does anyone have any opinions? Or, if it is a burrow, is there any way of narrowing down what might have made it i.e. trilobites/arthropods etc? Details: 1) Found in isolation/there were no other similar pieces nearby. 2) Measures about 8-12 inches long. Burrow notches are about the width of a penny. 3) Again, found in Carboniferous territory in Western Pennsylvania found in a creek. Thanks everyone!

I bought this fossil the other day, a Pennsylvanian amphibian or reptile print from Alabama (Carbon Hill). I have a fern fossil from the same site. I'm going to try and mount it to my wall if possible. Maybe put a wood backing with silicone glue, as it is fairly thin.

Trace in sandstone/ mudstone. Can anyone see more or ideas of source? About 4 inches across.

Found this, and a ton more, with my daughter over the years. Found this on Lake Michigan, near South Haven - Coldwater Shale Formation/Mississippian/Devonian There are lots of braciopods, from what I can see. Some having an amber looking coating, others having a metallic coating. Can anyone help with this, before I start to polish it (and let me know if I shouldn't). I've always just picked up rocks and coral fossils at the beach, and just now have really started to get curious....so I'm new to this, forgive me if I've missed anything. There are some close up shots, with a tootsie roll for scale...only thing I could find lol.

All-- On top of the ridge where we have built a home in the Missouri Ozarks, near Rockbridge, about 26 miles north of the Arkansas border, there are many, many fossils. Coral abounds. (Even I can identify coral.) There is a lot of other stuff, too. Here is a sample of that other stuff. I think it is a worm trace (is that the correct nomenclature?). If you have a moment, tell me what you think. It was found 300 feet about the level of a river. It was at some depth between 0 and 10 feet, doubtless closer to the 0 number than the 10 foot number. I discovered it on May 7, 2017. (Maybe I should make another GUESS just to be safe(r)!) Thanks. --Bill

What tracks have you found left on slabs of ancient sea/forest floor? Show-off here! My Crustacean burrow from Stratford Hall's Calvert exposures (SH being Robert E. Lee's home, so you get a mix of prehistory and history): Entrance: And the tunnel into the ancient seabed:

Arthropod resting trace

I found these in the creek back in September, this is the only pic I took (just now happened upon it in my files) and I can't find them to retake pics. The largest rock, the black one in the right of the frame, is no bigger than 2" at it's widest measurement, if that helps. I'm just really curious about what would make these little bubble-like formations printed on a rock like this. Bubbles?

Just an ID, please, there's a lot going on in this piece.

I'm not sure if this is an impression or trace fossil, so educate me on the difference please, but it's definitely something. I enhanced the color only slightly so y'all can see it better.

Footprint? New Jersey Late Triassic/Early Jurassic Continued
Kurufossils posted a topic in Fossil ID
Hello, this is a part 2 of my last thread with some of my other finds that I've found this at a site in new jersey where some footprints have been found from the Late Triassic/Early Jurassic, I am unsure about if these are footprints of sorts, any help will be appreciated thank you!.thumb.jpg.199bfe7f0722cff28ed302cdfb98578d.jpg)

Found this slab today. Early Pennsylvanian. The brown blotches are lepidodendron leaves I believe. They've stained the surrounding stone. Edit: I should probably add that it's from southern Indiana.

Last weekend decided to drive down to Missouri to catch the solar eclipse and look for some fossils in the Upper Cambrian Davis formation. My time was pretty limited so was only able to check out a couple different spots for short periods of time. Lots of worm burrows, disarticulated trilobites and weird trace fossils. The shale was pretty dusty so it was difficult to see what I was looking at in the field. I feel like I barely scratched the surface. Here's an interesting one with what looks like a long genal spine and water ripples (?). My understanding is this was a back reef lagoon surrounded by a microbial reef and the St Francois mountains were islands during the Cambrian. Not sure what's going here.... any ichnologists out there? Another plate with a lot going on. There are some small tracks on the middle far right.. Trilobite parts... Possible Cliffia lataegenae cephalon? Hard to tell for sure after half a billion years... Thanks for looking and for any insight!

Hi, I'd appreciate some help with this one, it's got me completely foxed and I can't find anything similar online. The matrix is a mudstone, it was a loose rock in a stream, the rocks in the area are all Brigantian (Upper Visean) - Carboniferous Cyclothem deposits (Northumberland, UK). There were 3 of these, all about an inch long, oval shaped, but fairly irregular, with faint radial lines/corrugations from a central 'spine'. They are three dimensional about a quarter of an inch thick. Small spiriferid brachiopod shell fragments in the same rock are undeformed, so I think the irregular shape is original. They remind me of small jellyfish but I think that's highly unlikely to have fossilised so I'm guessing some sort of trace fossil. All three are similar in shape and size so I'm wondering if there's a specific name for these, and whether it's known sort of creature made them? Cheers Steve

Can anyone with Devonian expertise chime in? I acquired this from sylvania shale. The fossil is about 4.5 cm in length total, and the tiny markings each measure anywhere from 1-2 mm. The markings vary in closeness and wideness. First thought was a trilo trail.

Gettings, I was recently visiting the north coast of the Balearic Island of Menorca and what I found there was a moon like landscape formed apparently between the Cambrian and the Devonian period, the area of the island is called Favaritx in case someone feels interested and I saw this strange drawings at some rocks, which I suspect that may be ichnofossils or trace fossils from echinoids or molluscs... What do you think? Thank you very much.

I have two Triassic coprolites from the Bull Canyon Formation, Quay County, NM. The first one has an impression/imprint that I have not been able to identify. The second has a protrusion sticking out of it. I had hoped that by prepping out the the protrusion, I would get lucky and it would match up with the marks on the other. Unfortunately, I now have two things that I can't identify. @Carl 1. Is there anyone out there that wants to take a stab at identifying the imprint in this one? It does appear that there are some remnants (white) of whatever it was that made the marks.

Came across this one along Hurricane Creek in Pope County Arkansas. At first thought it was a crinoid imprint but now wonder if maybe its just a trace fossil.

From the album: Ichnofossils
This is a trace attributed to a myriapod athropod (centipede or millipede). It is on the obverse side as the Nanopus prints in the previous image. -
It's been a long time since I've posted anything. I've enclosed a few photos of a recent find. I'm thinking it could be some type of trace fossil, but I'm definitely not certain. Any ideas as to what it could be? If even a fossil at all?

Hi guys, Just wondering whether you guys you help me identify some trace fossils and body fossils I observed within the Kilbride formation, County Galway, Silurian age. The formation derived from a shallow marine high energy marine sedimentary facies. The first is a trace fossil I first believed was man made - however it is not perfect spherical! It has a triangular hole positioned near the centre - must be some form of burrowing species? Another trace fossil I observed I believe to be simple sprieten - however it does not appear to be bounded nor does it appear to be u-shaped, I initially believed it to be an arthropod trace, however it was perpendicular to bedding. I also observed these two body fossils in an out of situ boulder, which I believe is the same formation. If not the same formation, the fossil will still be of Silurian age! Lastly (I swear), I experienced these unusual boudin like indents near the fossils, unsure whether biologically realted - any ideas? Thank you and much appreciated, James
