  1. Hello all! I was lucky enough to spend the afternoon today in the warm-but-not-too-hot sunshine at Mimico Creek in Toronto, ON (Georgian Bay Formation, Upper Ordovician), and I have a couple of things that I'd like you to have a look at: Picture #1: A view of Mimico Creek Pictures #2 and #3: A bivalve and a possible graptolite - what do you think? Pictures #4 and #5: An ichnofossil - do you think it could be Cruziana, or is it something else? Thanks so much for your help!!! Monica
  2. Possible Batrachopus Track

    From the album FreeRuin's Finds

    It looks the part of a Batrachopus footprint (missing a toe) with the proper size and location but I cannot say for sure. Hartford Basin Portland Formation Western Massachusetts
  3. Small Footprint

    From the album FreeRuin's Finds

    Either a small footprint or a partial one I believe it to be a Grallator due to its shape and size. Picked it up while hiking. Hartford Basin Portland Formation Massachusetts
  4. Ichnofossil ID

    Hello, I found these ichnofossils in a Eocene formation. Can you help me identifying them? Thank you
  5. Ichnofossil?

    I found these near the Valley of Fire in Nevada. From what I've researched, the area used to be underwater from 500 million years ago to 250 million years ago. I presume these are ichnofossils of a burrow made by some animal (brachiopod)? The first photo is a burrow in situ. The second photo shows all three burrows. What do you guys think these are? - Seann
  6. Hi all, I was wondering: would the steinkern of for example a Turritella be considered a fossil or an ichnofossil? Because in fact, the shell itself didn’t become a fossil, and what we are looking at is just sediment that filled in the shell and then solidified. But then again I’ve never heard of a steinkern being referred as an ichnofossil... So what do you guys think: really a fossil, or just a trace fossil? I am curious to see everyone’s opinion Best regards, Max
  7. 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!

  9. What's this trace fossil?

    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.
  10. What is name of the trace fossil?

    Hellow Guys, I have the doubt, the trace fossil of the picture is a rhizocorallium, diplocraterion or taenidium? Or none of those three?
  11. Haida Gwaii trip

    I was holidaying on Haida Gwaii (previously known as Queen Charlotte Islands) and had an afternoon on a beach near Tlell. We were actually keeping our eyes peeled for agates but I did come up with one interesting nugget. Maybe somebody knows what this might be?
  12. Phycodes ottawense

    While going through some old trip buckets, I found this at the bottom. I had initially picked it up because of its interesting appearance but forgot I had it. As far as ichnofossils go, it is a neat one with all its tangled parts, culminating in a kind of "mop head" appearance. I don't generally pick up ichnofossils, but this one was a notable exception. These are formed when organisms such as worms repeatedly burrow into sediment.

  15. Hi all, I just acquired this interesting specimen that was identified by the seller as Helicodromites mobilis. However, when trying to verify this, the images and description I've been able to find really don't seem to match. The whorls on this are flat and attached to the core. To me, it looks more like a cast of a shark egg case. Are any of you familiar with H. mobilis? Thoughts? Thanks for taking a look!
  16. Curiosity question for any of you who may have some Plio-Pleistocene coral samples from Florida or possibly elsewhere... I'm wondering if any of you knowingly or unknowingly have one of these crescent shaped fossil crab burrows as shown below? I was checking with Roger Portell at FL Museum of Nat History about some other types of traces/things and he shared a recent article he coauthored. Trace fossil evidence of coral-inhabiting crabs (Cryptochiridae) and its implications for growth and paleobiogeography Adiël A. Klompmaker , Roger W. Portell & Sancia E.T. van der Meij Scientific Reports 6, Article number: 23443 (2016) 've begun going thru all my samples and cant find that I have an example yet. Darn it! I'm wondering if any of you have one of these little traces? If yes, I'd love to see a photo! Here's a shot of them in Figure 2 from his article but they have other figures with other types of corals and locales.. Joe (Fruitbat) has linked the document in his reference section in Scientific American. Way to go Joe! https://www.researchgate.net/profile/Sancia_Van_der_Meij/publication/299392850_Trace_fossil_evidence_of_coral-inhabiting_crabs_Cryptochiridae_and_its_implications_for_growth_and_paleobiogeography/links/56f3be8408ae7c1fda297721.pdf?origin=publication_detail I see its also in Nature.com as well--not sure if there is any difference-I do like the zoom feature they have for the figures. http://www.nature.com/articles/srep23443 Hoping one of you has one! Regards, Chris
  17. Found in Watchet UK last year

    Hi All Last year I was at Watchet Somerset Uk and found the fossil attached i think it is a trace. I did initially think it was a fish but unfortunately not. thoughts greatly appreciated. The last one is I think a trace of a echinoderm. this came from Charmouth.
  18. Diplichnites gouldi

    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.
  19. From the album Ichnofossils

    Collected at the Union Chapel Mine in north-central Alabama. Age is Pennsylvanian. This is the counterpart of an 'underprint' just a layer or two beneath the actual track layer. The little guy's claws penetrated the mud and made some scratch prints at this level. At the top of this piece, you can see a trace perhaps a layer above the actual print layer. Here, a tail drag mark is visible.

  21. Here is one that has me stumped. It was purchased as a possible coprolite. However, unless the critter ate a lot of dirt, I'm thinking it is some sort of steinkern. It has a smooth texture on the outside (like it was coating in a thin layer of iron-rich silt, but is very gritty on the inside. It was found near turtle remains. I will post a microscopic image in the next window. I have come across similar configurations (on a much smaller scale) in the Rattlesnake Creek micro matrix, but I don't know what those are either. I apologize in advance for the quality of this photo. I would happily retake it at a better resolution if anyone thinks it would help. Thanks for looking!
  22. From the album Double Duty

    Here is a microscopic view of the possible feeding trace. This to a YouTube video shows how the mouth parts of a modern urchin move while they eat. Age: Jurassic - Kimmeridgian Formation: Solnhofen Limestone (Plattenkalk) Location: Eichstätt, Bavaria, Germany

  23. Hi all, I came across this tiny star shaped ichnofossil while prepping Lumbricaria I recently received. It measures about 2 mm across. I know something like it was posted on the forum not that long ago, but I can't seem to find it. Do you think it's an ichnofossil or just a mineral deposit? I have included photos of the Lumbricaria as well, including some micros of what I think are partially digested pieces of brachial segments. As always, thanks for your help!
  24. Ichnofossil from Mimico Creek

    From the album Urban Fossils of Toronto (Georgian Bay Formation, Lower Member)

    Various ichnofossils made by the fauna of the Georgian Bay Formation. Found at Mimico Creek, late Ordovician.
