Headed back to area where these were collected this weekend (Crane Hill, AL) & would like to know if I should keep collecting similar rocks? If fossils present, how can they be better delineated? 3 Specimens: 31-trackway? 30- 29- Not sure the best angle for this one so multiple pics. Last 2 pics are the back.

I’m probably getting close to my question limit for today, yet I can’t stop thinking about the pattern on the rocks. Are they trace fossils or just pretty iron staining? I’m headed back to where I collected these (Crane Hill, AL) tomorrow & it would be nice to be able to explain to my nieces. I was thinking about Graptolites, though I can’t match up the patterns to those I see in my books. Google search of pic 1/2 pulls up Stromatolites. Pic 3 is the back of pic 1/2 pic 4 includes more examples Thanks for looking.

went hunting in virginia triassic looking through red stones in construction zones. Didnt find much, the one thing I found looks like a trace fossil to me, though I dont recognize it. I am open to suggestions, the trace is 8c m by one cm of a looking like series of circular flat disks on a thread.

Upper Ordovician ichnofossil - bifungites (?)
Rogue Embryo posted a gallery image in Members Gallery
From the album: Camille's fossils - Georgian Bay Formation
This dumbbell-shaped ichnofossil measures about 7.5 cm long, including the terminations -- considerably longer than the Ordovician and Devonian bifungites specimens described in Pickerill and Forbes, "Bifungites of Halli from the Ordovician (Caradocian) Trenton Limestone of the Quebec City Area" (1977).

I came back across this fossil after taking another look through my Mazon creek collection. It looks like some type of creature with a preserved trail? I had previously missed it, thinking it was part of plant material that it is associated with.

My son found this in Lost Creek in Russellville, Alabama. I am assuming it is a marine trace fossil but someone locally had another idea that is so far fetched I won't even mention it here, LOL. I figured I would check with the experts to see if they agreed with the simple explanation first. Thanks! Ramona

Trace fossils aren't always as exciting, but I like the ones I've found. This looks like a burrow cast. From the "mottled member" of the Chinle Formation, Temple Mountain, San Rafael Swell, Utah, US. Posting also to check my identification. My references indicate that the mottled member at this locale is known to have lungfish burrows ... unless they're crustacean burrows. This one seems large for a crawdad (even a Triassic crawdad) but small for a lungfish.

A fossil buddy sent me these photos. His thought was trace fossils, but looking more closely, it seems to me these might be graptolites. I confess I've mostly hunted in beds well past the geological peak of graptolites and are not as familiar as I might like.

I just found this piece in a parking lot in Ann Arbor, Michigan. The stone was taken from some quarry and dumped here, so there is no geographic or temporal control, but I was wondering if it was a trilobite (since that's what it looks like to me). Thanks!

Hi everyone! I recently found a trace fossil near my house. I live in Southeast Colorado Springs and there's a lot of marine fossils near where I live. I found what I believe is an ammonite trace fossil. I'm having some trouble identifying it though. I'm not exactly sure what ammonite it's from as well as what formation it's from and what type of stone it's in. I brought it in to the museum I volunteer at and it was determined by the curator that it is not sandstone and it's most likely from the Late Cretaceous. I think it might be from a Hoploscaphites cheyennensis in silt-stone from maybe th

I already had 2 little piles of worm tubes then I found this larger single one today and appears the tube broke and exposed the worm. Examined the smaller ones more closely and noticed they have pyritized insides and cracks like on shell, started to wonder if they were gastropods, I see shiny spots and know the worm isn't preserved and tubes aren't shiny so doubting if they are Serpulid tubes. Also see what appears to be apeture on larger worm, so what are they? Last picture is backside of large one.

trace fossils. I hadn't really found that much variety in trace fossils from the area. The largest is easily 2 inches in diameter -
Eagle Ford sandstone, found a cool trace fossil and curious what made it. Could only find one somewhat distinguishable thing and really can't tell what it is other than looks like shell. Lots of burrows and maybe worm? Found several little circles with dot in the middle but hard to get all images. The trace looks like a sperm best way to describe it.

From the album: Ichnofossils of Platteville to Decorah Formation Twin Cities
The fun part is when I lifted it out of the ground a chuck fell off, revealing this gorgeous calcite geode inside where sediments didn't fill this burrow 100%. -
I am just stumped on these. All came from banks of canal at the bottom of a hill. These are all on the shallow level side of canal amongst sandstone, and they are everywhere. On other side of canal a little further down it's grey clay with big red concretions and fossils shown but these aren't present. These whatever they are aren't very heavy but hard like limestone. Only found one with inclusion, and broke one open and it's smooth. Included pictures of both. They kinda stick to tongue.

Why is the difference between fossils and trace fossils important?
Daniel Fischer posted a topic in Questions & Answers
First of all I want to make it clear that I know what are trace fossils an I know the difference between fossils and trace fossils, but I feel like I am missing something. In a few posts here on the forum I saw people saying things like "this is not a fossil, maybe a trace fossil" and things like this and I do understand that regular fossils give more information but can anyone please explain to me why it seems like trace fossils are worthless compared to regular fossils? -
I found a few plates of sandstone that I really liked a few years back in Lockport, NY. I believe they are from the Silurian Grimsby formation. I don't remember nearly anything about trace fossils. My first guess from just googling before making this post was arthrophycus. Can anyone tell me what kind of trace fossil is present in these pieces? 1. 2. 3. 4.

This came from Eagle Ford Kef creek, I have collected odd burrows but this one appears to have things in it. Anyone recognize anything? Can there be concretions inside a burrow? Pictures show wet and dry.

Found this on the Elm fork of Trinity river bank, Cretaceous Alluvium. I have found clams, baculites, ammonites and crabs there. This slightly resembles a piece of baculite, size suggests clam burrow. Appreciate an ID!

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. The 20-million-year old lair of an ambush predatory worm preserved in northeast Taiwan. Sci Rep 11, 1174 (2021). https:// doi.org/10

Hello everyone, I have posted about this fossil before but I was not able to get it Identified. I have decided to create a separate topic for it because I am quite interested in if this is really what I initially thought it was. The fossil is from Eifel (Middle Devonian) and on one side there are a bunch of Crinoids columnals, but upon flipping it over I noticed this darkened branching structure on the rock, to me it looked very reminiscent of certain algae, although I have never seen anything like that from the Devonian so it's probably something else. So my question is:

I don’t know anything about ID’ing footprints so hopefully you guys can help me. It doesn’t look like one to me but I’m still curious. I don’t know exactly where this was found as it was given to me so unfortunately I don’t know the formation.

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.

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
