    Found in France

    Hi! My son found this in France in a river, region center , it’s quite unusual so I thought I’d show it to you guys. Any thought? IMG_3992.MOV

    That's a great find, Jeff!

    I'm leaning towards it being a coprolite. Is it about 2 to 2-1/2 inches long?
  6. Howdy y'all! I have found a few interesting things that I could use some help with ID. These are all either Eagle Ford, Del Rio or Georgetown Formation. Any help is appreciated! First are the teeth: Are these Protoshyraena teeth? That's what I was able to find online because they look an awful lot like Barracuda teeth I've found in the Miocene. 1 and 2 :Two teeth - top row and bottom row. Both are about 1/4 inch 3, Assuming this is some kind of Fish Tooth 1/8 inch 4. This is an odd thing. I have found Ray teeth here, but this doesn't look
  7. If I remember correctly it's around 6 cm long. I don't take photos with scale, sorry.

    At least I have an excuse and it's not pure laziness this time.

    That fits nicely. (Note that Hederella is no longer thought to be a bryozoan.)

    Baked mud or skin?

    Looks like weathering of a sedimentary rock which accentuated the pattern. I'm not sure if drying is how the pattern was created though. .
  11. I’m so jealous, that’s beautiful! What’s the scale on this?
  12. I guess we start over the count-down: Ediacaran, Andiva ivantsovi, Russia.

    Thank you! The first was found in a rock with brachiopods, horn corals, crinoids, and a trilobite. The third is Devonian so that kind of bryozoan is very possible:)

    Fossilized mud?

    The last view is clamish looking.

    Baked mud or skin?

    Hi folks! I'm a total newbie at this but found an unusual block at West Runton beach, Norfolk. It's 3" x 1" x 1" approx, with a clearly defined print on one face. The whole block is quite uniform in colour, but there appears to be an underlying structure which can be seen at a couple of corners. I've not seen anything remotely like it at West Runton before so it stands out a bit. My best amateurish guesses are either solidified baked mud or some kind of skin print- but given the find location I'm not sure either are very likely! I hope someone can be more definite!

    Really lousy paint job. Skull is deformed. Result = squidward.

    Already posted this on on another forum.  Had one gent or gal say was a horse tooth which I agree.  But also stated was modern. 
     

    it is pretty much fossilized and rock. Say semi fossilized etc.  river and weather worn also.  
     

    have found many other bison tooth’s that are old and brittle and jaw bones with teeth nothing like the composition of this tooth that makes almost rock. 

     

    Any others has ideas.  A extinct horse that roamed north tx long time ago ?

  19. That's the left "nostril". The right side is missing, as is the back portion of the skull. I think it may be of the American Black Vulture.

    It does look like a Knightia eocaena. It is very poorly painted over, however. They do this to make the fish "more attractive" to buyers. You can see where they missed the real fossil with paint. It probably wouldn't have any color otherwise, and would just be an imprint. Not sure the paint can be removed, however, as Green River matrix is very porous. Cropped and contrasted:

    Fossilized mud?

    This is a steinkern partially covered with minerals that would make a pseudomorph of the shell if the process was complete. Sort of what Rockwood says. Aragonitic shell is dissolved and then gap is refilled with calcite.

    Let's see your latest mailbox score!

    It's an excellent specimen, and I hope I'll at one point have opportunity to add a fossil like this to my own collection. It's just such a cool specimen! As to which of the two polycotylid plesiosaurs the jaw could be from is indeed somewhat problematic, since no adult Manemergus anguirostris individuals are known, while no juveniles are known from Thililua longicollis. Since your specimen conforms very well to the holotype of M. anguirostris in size, and that's a juvenile, I suspect that your individual was also a juvenile. Further complicating matters is that Fischer, Benson, Dr

    Is this a Khightia? If so, why does it look like squidward? Im only assuming it's from the Green River because I found it in a box with stuff that is definitely from the Green River.

    The first one looks very much like a trilobite eye. The third is possibly Hederella.

    Reminds me of an elephant's foot.

    looks like amygdaloidal basalt

    Fossilized mud?

    Interesting; it looks like the (clayey) core of a concretion with an outer layer of gypsum, although we are not sure that the gypsum layer formed a complete envelope around the mud core (or have you seen some like that?). But the direction of growth of the crystals is towards the surface of the clay core, so the surface from which the crystals enucleated is missing. I have seen selenitic gypsum crystals growing on muddy layers triggered by bacterial activity, but that was in a cave environment. ciao

    Nautiloid or crinoid?

    Interesting one, do you have a pic of the cross-section? Reminds me to a orthocone cephalopode, something like Gorbyoceras / Striatocyloceras but, when I see your tags seems to come from wisconsin perhaps Spyroceras, when I compare plate 6, fig a in Common Paleozoic fossils of Wisconsin
