  1. Wrangellian

    Couple of Mazon Creek IDs needed

    This one was sold to me as the acorn worm Mazoglossus ramsdelli... it seems to match photos I see, but I'd like a second opinion, please: This one was sold to me as Archisymplectes rhothon ('ribbon worm') but I'm less confident about this one, so, same question as above. If it's not that, what is it?
  2. Another day of great finds in Saskatoon! This time, some trace fossils. With my wonderful collaboration with the University of Saskatchewan's Museum of Natural Sciences still continuing, recently I have been very lucky to make multiple trips out to a beautiful site just outside the city of Saskatoon where massive deposits of glacial lake silt are exposed. This silt produces pristine grass and other plant fossils in abundance (I'd like to make a post about them soon as well), but also seems to be teeming with various invertebrate trace fossils. All are very small (under 1 centimetre wide). I've attached some of my best pictures below. 1 - 6: Overlapping Planolites sp. closeups 7 - 11: Edaphichnium sp. 12 - 14: Taenidium sp. closeups 15 - 16: Taenidium sp. wide shots 17: Taenidium sp. closeup

  4. I found this rock in a creek bed in Colorado springs. There are a few worms that are almost a dark glass color that seem to have gone through the rock. There is also evidence of the impression of the head of a worm at one point and the "side view" of a more squiggly worm on the front. Question 1. Anyone know what types of worms are those? Question 2. Why are the worms stuck inside made up of a different type of rock? Question 3. Should I cut the rock to get a better look at the shiny worms inside? Thank you!

    Fossil worm burrows

    Hi all I found this today on rt51 between Anna and Carbondale in southern Illinois. Can anyone tell me if I'm right thinking they are work burrows or something else Thank you

    worms?

    Hi all, I've been finding pebbles in a park with paleozoic age fossils in them - rugosa, goniatite and this one has something that reminds me of worm trace fossils. I believe the gravel is from the Drava river, which may carry it all the way from Slovenia and beyond.. Any ideas?
  7. I have no information about the location. Is this a sponge or is it a worm colony? Modern or fossil? It has a waxy texture to it, I originally thought it was plastic. Thank you!

    Worm?

    Hi Firstly location, I live in South Norfolk. Recently, when rotovating my garden, the blades split a piece of flint and one half had the impression shown on the attached photo. It looks a little like a worm but that’s the guess of a novice. Can more enlightened forum members suggest what it could be. Regards Les Wilcock
  10. Hi everyone. I'm doing a project on earthworms, and I was hoping you might be able to provide the names of some dinosaurs that existed in at the same time and in the same geographical locations as early earthworms, in periods of both extreme cold, and extreme heat. So for example: X Dinos existed along side worms during the extreme cold of period (or dates) X X Dinos existed along side worms during the extreme heat of period (or dates) X I've been cobbling together bits and pieces from Google and thought it couldn't hurt to seek the advice of experts. Any help would be greatly appreciated. Thanks in advance. Best regards Mike.

    Serpulid Reef?

    Awhile back @Rockwood posted something similar to this and was given the ID Serpulid Reef, which I had never heard of until then. Would that be what this is? This is from creek in Eagle Ford, what's most curious is how the wad of spaghetti perfectly comes together at the mouth(?)end. Pictures I've seen of these reefs show worms poking out out in every direction.@erose
  12. I found this fossil in the thar desert near jaisalmer india Is it a worm or corals or any other prehistoric marine creature I found this near akal fossil park , sam sand dunes Please help me identify it Moreover I also found a ammonite fossil near it.

    Help identifying

    Found this rock that's smaller than a dime this evening outside my house. Noticed it looked like worms in there. Information if it's a fossil, and if so, other information greatly appreciated

  16. So.....I was splitting my last piece of Pennsylvanian stark shale member, between Winterset and Bethany Falls limestone from a 2x2' 2" thick piece, I found some cool conodonts, a lot of scolecodonts, and amassing a pile of split shale, when I came upon yet another listracanthus/fish spine, about 5-6cm in length and very slender (2-3mm in width). I have both positive and negative pieces (depicted here). I scan all of these to see the pattern, faint impressions of a wider segment (as seen in photo 6 ), and in this particular specimen noted the shiny black cracks and creases surrounding the fossil. I see this very commonly in shale (and my understanding is it reflects rapid cooling of heated material?). In addition however, I saw what simply appeared to be conglomerations of, for lack of a better term, "worms" (Circled in blue in photo 2 and red in photo 6). Now stay with me on this one! Under microscopic evaluation numerous ''nematode" shaped objects adjacent to the spine are present, measuring 0.3-0.8mm in length are noted. Most are broken but there are some mostly intact. Several demonstrate fine "annelid" rings, (denoted by arrows) but I don't think these are annelids? At first I thought the preservation was too good to be real, but I have denoted numerous impressions in the shapes of worms, even to the point of the "rings". In reviewing nematode and annelid taxa, I don't see any mouthparts to make these polychaetes, and found reference to "ringed" nematodes. I hope someone can confirm or tell me if these are something else. I have placed circles (blue and red) around the groups, and arrows on salient features of impressions and the worms themselves. Also labeled a couple more intact individuals with an "N", but most are broken. If this is a reasonable observation, then this is one of the coolest things I have ever found!!!!! Fingers crossed I am on the right track!!!....Worst case, it is a plant piece with adjacent plant nematodes, which are very common nowadays and worst worst case, I am totally off track . There are 13 photos, with some seemingly one image but if you look close, they are separate if that helps. as always, thanks all!!! Have fun with these and let me know!! Bone

    Some worms?

    Hello! What it could be, for me looks some worms, but may be I am wrong. Max length - 0.9 cm Western Ukraine. (Cretaceus-Neogene) Thanks!

    Annilids?

    Hello! Here are several photos of a fossilized colony of some sort of worm, or so it appears to me. Please excuse the remnants of clear nail polish I used years ago to increase contrast before I knew better. I came across this in Santa Paula canyon about 2 miles northwest of highway 150 where it turns west at Thomas Aquinas College, Santa Paula, CA. It had washed down decades ago from probably a Matilija Formation exposure. The matrix grain seems quite fine and the rock is very heavy. Although I've been up and down the creek countless times, I've never seen the source bed. Eocene oysters, clams and echinoderms have been collected in the canyon. Thanks for your help.

    Worms?

    I found these on a beach in Illinois in a small lens of pyritic sand. I believe they are worm tubes but not entirely sure. They are only visible under microscope and occur with pyrite framboids. So my question is, are they indeed worm tubes, pellets, or something else? I can only assume they occur at the beach because of erosion of Silurian rocks placed there, but not sure of that either. In this pic below, you can see partially inside the tube which features spheres of pyrite. It's my understanding can be produced by worms. framboid Thanks for any help!

    GIANT BACTERIA?

    After my move to Florida, as I unpacked my fossils, I came across this. Any ideas? Possibly giant bacterium or microscopic, cigar-shaped alien space craft? Algae? They are ~3mm long. Salona Formation. Trenton Group Middle Ordovician Antes Gap, PA Tom

    Trace fossils? Coral? Anemone? Worms?!?

    Hey there! This is my first post on The Fossil Forum. I don't have a lot of knowledge about fossils, but I sure do know how to find them. Hopefully these aren't too obvious and boring, but I'm incredibly curious anyway. I found these near Sheep Bridge north of Phoenix, Arizona. Here the Verde river has cut through deep layers of ancient lava, sandstone, mudstone, etc. I was exploring for crystals up on a steep hill along the river's canyon walls when I came across a whole lot of these things. They are very fragile and I didn't want to break apart some of the 2-3 foot wide boulders of them so as to preserve them for others to find. Anyway, my understanding is that this area was once a sea floor, so I'm assuming they are some type of coral, anemone or something similar. The fossils are composed mostly of the same sediment which encases them, so I suppose they must be trace fossils, but please correct me if I am wrong. Other not-so-filled-in ones even had crystals and other minerals lining the cavity. As well, I looked at a geological map of Arizona and the area I was exploring is composed of the following... Late to Middle Miocene Basaltic Rocks (8-16 Ma): Mostly dark, mesa-forming basalt deposited as lava flows. Pliocene to Middle Miocene Deposits (2-16 Ma): Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. There are a couple photos of some ball shaped objects which were very easy to knock apart from the surrounding stone. I have no idea what those could be. The rest of the photos are of the coral looking objects. Some of them, if still intact, were nearly 24 inches long, but I left those behind and only took smaller samples. Please note how the "head" of the corals appears to flare out and is larger than the rest of the stem. Finally, some of them appear to have a little node sticking out of the "head," but I suspect that may be due to weathering as these are very fragile fossils. Thank you all so much for your interest and help and I look forward to learning more!

    Fossil ID needed

    Hi everyone, I was doing a beach cleanup on Sunday along the Port Tobacco River, & I noticed this little rock sitting next to an old beer can. It is 3 cm wide at it's widest point. The whitish grey color made it a challenge to photograph, so I added a slight wash to it. Any help with an ID would be greatly appreciated. I looked at many images of worms last night, but I didn't see anything with the same shape or length, & without knowing the age of the rock, I am not sure how to identify it. While it is whited out in the middle, when I look at it under a magnifying glass I can see that the horizontal lines extend through almost the whole length of the ovalish shape. This photo was magnified 2x. Thanks for looking!

    Fossils??

    Found Glen Rose TX area... this is very interesting to me. It has many different imprints. Could someone tell me if they are plants, insects, worms or all of the above I would really appreciate it
  24. From the album: 1925 Body & Trace Fossil Collection - Ocean

    Once you start looking at this specimen the tiny Crinoid Ossicles just keep appearing. Worm holes have not been vacated.
