  1. Egg Mold from Jordan

    hello, I found this egg mold close to my house, there were an excavation, i found it in the dirt they bulldozed away. (it wasn't broken when i first found it, it fell by mistake). from the other side it's just a normal orange-ish sedimentary stone(i don't have enough media MBs left). And, I see these orange lines in the bottom of the stone too often on other stones i want to know what they are. thank you.
  2. Fossil tooth mold?

    Dunno if this is wishful thinking, or a real tooth mold, but here it is. Longest side (right) of the tooth is 2.25cm long. The whole thing is 6cm x 4cm with the odd dome to the left being 2cm thick. I have pics of other angles and the backside as well. Just saw it laying partially buried in the ground in an empty field in Central Washington State this morning.
  3. These are all in the same stone. Wondering if it's 3 different preservation types of the same species. Found in Sw fl, in the sand. Trying to learn to recognize familiar players in their various forms and stages of erosion. Couldn't get the tape measure next to two of them, but they're both 2.5 inches long on the nose. The one that looks like a unicorn horn(w/ tape measure) was what caught my eye, rimmed with grass it really stood out! Its shimmery and beautiful. Is it ok to chip it out? Far from its margins, of course. 3rd pic following...
  4. Snail?

    I found this cast? Mold? Unsure of the correct terminology. I looked at the usgs website and they said snails were unlisted. I wondered if anyone had any helpful information they would share.
  5. Exoskeleton

    Any ideas on names?
  6. Tiny bubbles

    I found these in the creek back in September, this is the only pic I took (just now happened upon it in my files) and I can't find them to retake pics. The largest rock, the black one in the right of the frame, is no bigger than 2" at it's widest measurement, if that helps. I'm just really curious about what would make these little bubble-like formations printed on a rock like this. Bubbles?
  7. Tiny calyx ?

    I found this the other day, in the cab of my pickup, while looking for ski wax. I often pick things like this out of the gravel I'm shoveling during the fall. The bulk of this material is Devonian marine rock. Bits of plant do show up now and then.
  8. One more before my phone dies!

    Just an ID, please, there's a lot going on in this piece.
  9. I think I see a crinoid, but what else?

    I'm getting braver and will venture that there is at least one crinoid columnal mold preserved in this formation. I'm fairly certain, however, that the other two most prominent molds are not of a crinoid. How am I doing?
  10. Devonian shell

    Another shoreline glacial find. Most likely lower Devonian marine delta related. The first shot shows part with scale, and inverted counterpart to the left. The last shot is of the under side of the fractured section in the photo before it.
  11. Is this a trilobite mold?

    Howdy. Found this in Central NJ. Is this a real fossil? Anyone know the type? Thanks
  12. Mussle Shell Steinkern

    This is a particularly fragile type of shell, made of many fine layers, and is prone to disintegrate as these did. This rare steinkern was found on a block of matrix submerged in the Chesapeake Bay. Dimensions are for the best-exposed steinkern on the block. The entire block is 14 cm wide x 10 cm high x 5 cm deep.
  13. Please clarify for local discussion. Referencing the attached sketch: First is a coin simulating a fossil. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Second is a lens shape, like a saucer or moult of a pygidium. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Third is an egg or complete bivalve. If split at the red line, there would be 2 pieces of external mold and 1 internal mold. Correct ? or incorrect ? All 3 assume that the specimens have dissolved an left a void which if filled would be the cast. Correct ? or incorrect ? The local argument is that the pygidium moult example is 1 external mold (top) and 1 internal mold (bottom) because it is the "internal" side of the animal. I don't think that is correct. Just a local discussion needing clarification, thanks. ref: http://www.ucmp.berkeley.edu/paleo/fossilsarchive/casmol.html
  14. I found this crystalline calcite replacement fossil mold after breaking open the width of a 2" to 3" thick Eagle Ford limestone layer loose fragment. The rock broke along the circular arc of the fossil mold. The mold is somewhat mushroom shaped with a small inoceramus clam attached to the side. It is about 4.25" wide. A full circular arc might be more than 6 inches in diameter. The mold appears to be fragmented and hollow on the top of "mushroom shaped" side. The narrower bottom of the mold also flared out a little, but not as much as the top. I think that the thin base layer cutting at 30 degrees to the mold is an oyster shell hash layer that it was deposited with - although at the mold top the hash layer to be unusually smooth faced. Some of the calcite mushroom lip broke out on the other fragment (the 4th photo shows it upside down on the bottom). The lip was not likely to be easily recovered. So, I cut that face of the limestone fragment back from the lip so that the two can fit together where you can still see the concave fossil surface inside. I worked off the convex outer matrix of the mold and the micrite limestone matrix until there was little else left but the mold. The oyster hash (or other) layer and the small inoceramus are also attached. The limestone layers in the outcrop area has some 15mm or less tooth width sized Ptychodus and up to 12 to 20 mm long cutter shark's teeth. There were also two ammonite molds (10" to 12") preserved in similar crystalline manner. There are a few shark verts and fish/ray teeth also. The few Paleontological Society of Austin folks I showed it to at the recent meeting could only see the concave face before I had carved it out more. They would not try to guess its origin. My first inclination was that it is a large vertebrate bone fragment. That might have been just well wishing. A giant inoceramus hinge plate or other large invertebrate (like ammonite or nautiloid) interior mold seems more likely. Any educated guesses? Thanks in advance for your time.
  15. Stromatoporoid 2

    Is this one more recognizable ? It occurred to me that a lot of people may not know what the real structure of these is. Figured it wouldn't hurt to make sure I'm not one of them
  16. Devonian Delta

    Found in Maine glacial material. It was among Mucrospirifers, in what seems likely to have been a marine river delta (Taratine formation).
