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.

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

Hello, I found this interesting looking specimen in Port Charlotte, Fl. It is 2 inches (50.8 mm) long and 1.25 inches (31.75 mm) wide. It has teeny tiny honey colored calcite crystals in the segments and in the crack in the one end. I can see the crystals with a flashlight. I have many shrimp burrow casts but none of them are segmented, this is what it reminds me of though. Thanks for looking. Marie

Found in Pennsylvanian layers; shale, mudstone, lignite, in Illinois; petrified wood nearby. Is this dinosaur poop?

I've been adventuring my family property in north-western Pottawatomie county, Oklahoma, for 15 years or so and I've always thought all this sandstone was kinda boring - there didn't seem to be any obvious strata, or differences in composition and no fossils. On Christmas day, however, I went out on the family property to do a bit of photogrammetry of the sandstone outcrops on the property and I stumbled upon a very interesting pattern in the sandstone: I have been told that it looks like bioturbated sandstone, and it certainly looks like some kind of biological pattern. This sands

Hello everyone, what is that?

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.

Attached are photos of a fossil rock my son found in the eastern TN mountains in May 2017. We had stopped near the top of amountain in the Clinch Mountain range and this was sitting in small wash pile on the side of the road (it had recently rained; I had been told by a UTK Paleobiology professor that the mountains around Bean Station and road cuts along highway 25E in that area might yield Ordovician fossils, as many would weather out and could be found lying on the ground). I believe that these are mostly trace fossils - fossil burrows or thalassinoides, along with some corals and brachiopod

Hi all, Is this a trace fossil, worm holes? If yes, that would be the first I've found. The holes measure about 1mm to 2mm in diameter. I think it's odd that all of the larger diameter holes are perfectly parallel to each other, while the smaller diameter holes seem to run perpendicular to the larger ones. Also, what are the dark thread-like shapes all over this rock. I've never seen those on my finds either. Rock measures 2cm tall, 1.5cm wide. Lake Michigan beach find, WI, this could be either ordovician, silurian or devonian. TIA! front:

I'm not too hopeful about this one. But still a cool rock.

I picked this up at Salamonie State Park in Huntington County, IN. Someone suggested it might be an icno fossil? 4.5 cm x 1.5 cm. Thx!

Hello, first post, so apologies in advance for any unintended transgressions. I found this one in Big Brook, New Jersey among the plethora of trace fossils usually attributed to shrimp, that are usually disregarded by most hunters here. (I personally find them kind of interesting, and have a lot of fun when I bring them home and tell my wife they are "witch's fingers.") Usually the tube is more rounded and longer and yes, "finger-like." This one is tear shaped and flat on one side. I have seen similar shaped fossils online attributed to insects. There is also an old post here of a simila
