  1. Vertabra

    Searching through some matrix I found this partial vertebra. Wish it was a bit more complete but maybe next one. This was found in marine sediment from near Richmond in Central Queensland Australia. It is from the Toolebuc formation witch is Cretaceous Albian about 98 - 100 million years old The longest length dimension is 6.5 millimetres so the animal it comes from must have been huge Also interested in where on spine this would have been situated if sufficient information can be gleaned for this partial. Thanks in advance for all input. Mike
  2. Can't ID bivalve

    This is probably an easy one for you guys. I have around 20 of these, so they must be common, I just can't seem to find one online that matches them. Sw Fl. Thanks!
  3. Sand dollar pieces?

    I keep finding these, always broken, always in the kind of ground that looks like and literally has the texture of the inside of a Butterfinger candy bar. Kinda look like little rock tacos, lol. They're rough like sandpaper and brittle. Bits of sand dollar? There's just not enough for me to tell. Sw Fl. Thanks in advance!
  4. Bones or shell?

    Good afternoon all! Finding myself confused again. Pulled this out of the ground this morning, SW Fl, and not sure what these are embedded in there. They remind me of fish or rodent bones, but I'm just stabbing at a guess. Could just as easily be tricky shell bits. I haven't done anything to it, because I don't know what it is yet. If it's shell, it goes away, if not, I clean it. (Sorry pics not so crisp...tremors...)
  5. Something coiled

    Is this an ammonite? It's not exactly round, and I don't know if an ammonite would compress like this. It would be cool if my daughter had found one, though!
  6. Is this horn coral?

    Today I have some more playground finds. I think these fossils are agatized? They are very shiny and have a striated, yet bumpy texture. The only thing I can think is that they're some kind of inside cast of horn coral, but they almost seem to have had branches due to the knot-hole appearance on two of them. Two of them have hollowed-out ends.
  7. Hi, I found these while pulling apart loose shale eroding from the rockface at the Lady's Walk Shale, Scotland. Be interested for any thoughts...! Can upload better pics if needed.
  8. Cool fossils in NE Alabama

    Guys, I’m totally new at this but I think I found a super cool formation of sedimentary rock with marine fossils in it in Northern Eastern Huntsville, AL area. I’m going to take a wild guess and say these are Mississippian (one looks like a crinoid stem) but you guys would know better than me. Anyway, it was awesome to pick through a little bit.
  9. Tiny something...

    Apologies, but this was hard to get a pic of. I had to use a magnifying glass under my camera. I don't know what it is, other than tiny and black, and I *think* it's fossil, but I could very well be wrong. But I'm curious! Just popped out of matrix around an oyster when I was digging it out. Any ideas? (In sw Fl.)
  10. Shark tooth

    I found this tooth with shells from the Plio Pleistocene, I'd imagine that it'd be from the same time frame? I'm awful at shark teeth, any help is immensely appreciated. (I forgot to put Fl.)
  11. Where the heck?

    The Delaware Bay and Delaware River shores are littered with lovely marine erratics. They aren't local. They aren't young. You have to dig pretty darn deep in Delaware just to get to the Cretaceous in some places. These are Paleozoic. Many pieces are limestone and probably from the Mahantango FM. But, I find just as many that are definitely not limestone. They are silicified to cert and other shades of SiO2 plus a bit of dark blue/black mineral. I'm thjingking they are ordovician, based on the Foerstiphyllum sp. corals here. The puzzle is, where do they and the other silicified corals, sponges, bryozoa etc, come from? The DE geological Survey doesn't even mention the erratics. I was told that it's been washed down from the Appalachians. Okay, there are definitely ordovician layers there that could have eroded into the river, but all I can find are formations of limestone and fine-to-very-fine grained sandstone. Been doing all kinds of searching through descriptions of geological formations in the area and I'm coming up blank. Anyone have any ideas?
  12. Cast of what?

    I picked this bit of oyster shell up because it has pretty barnacles on it. I started cleaning mud out and a chunk fell off revealing this. I thought maybe a gastropod cast that's settled in, but it looks attached? It's also not evenly spiraled. It doesn't show in the pictures, but the fatter section has an undulation to it. Worm cast? Anyone know what it is? (Sw Florida)
  13. Triassic mystery bone

    Hi all! I've found this strange bone (unprepared yet) in triassic aged sandstone from the anisian. In the same location there have been many shark, fish, and Marine reptile species reported. I can't seem to I'd what part of the body this bone represent, not even talking about the species... The bumps on the surface are half spheres, some of them protruding half way without squere encourage, I think they can be teeth or some kind of dermal plate. So, does anybody care to share their thoughts on the matter?
  14. Vertebra Queensland

    Looking through my usual matrix I came across this partial vertebra that has me stumped. Both sections were sitting together in the matrix so assume they are part of the same vertebra. Definitely not fish so some type of reptile ? Hopping the process end is diagnostic enough to determine species. Second piece in post below Mike
  15. Fish scales

    I came across some interesting fish scales when looking trough some matrix. ruler scale is .5 off a millimeter so all are about 3.5 mm in width so fairly small. The scale on the left has a small curve and the others are flat. the specimen on the right is fairly common but the other two are the only ones I have found and both were in the same small batch so could be from the same fish. Any ideas on what family of fish they come from? Mike
  16. Cretaceous Bird

    looking trough some matrix I came across this little specimen. When it was complete it would have been 40 mm in length. Unsure of the orientation of the section of bone on left end and small section in middle is upside down, but due to this being very delicate, I am not going to play with it. The bone is hollow, thin walled and filled with calcite but the bone will chip easily so this is the only photo as specimen now in small case so as to not damage further. I am comfortable with this being bird as it matches the preservation of the other pieces found in the area. I assume it is an ulna due to the curve so it would be the only one known from this species. The other bird specimens from this local are assumed to be enantiornithine, but only time will tell for sure. Mike D'Arcy
  17. Inner part of something, or worm?

    Found 2 of these, identical in size, in sw Florida. What the heck are the wormy things? Is it internal bits, or worm casts? It's really hard to find online because I lack the terms to use to search effectively. Really appreciate all your amazing help lately. Hopefully I don't get the boot for too many questions! lol
  18. Same pattern on many rocks?

    Does anyone know what this pattern is from? It is on the surface of a large number of rocks in the area. Those rocks are always rich with fossils, if that's pertinent. Is it from sponge? Shell? Its circles in oval-ish shapes. Its hard to get it to show on camera, sorry. When I go outside today I'll try and get a pic of one in situ if you think that might help. (In sw Florida.)
  19. Bone identification

    Got pulled out of a few hundred feet of water near nova Scotia.. not sure there's enough to ID it. About 14 inches long and maybe 3.5 inches wide at widest point. img]http://pooncheese.com/images/2018/06/05/86fb790edcb634f95ec1795e1c204a51.jpg[/img] ,
  20. What kind of shell?

    I found this little guy with a cluster of barnacles in sand in the woods in sw Florida. I can't figure out what shape it was, or is it two stuck together? Looks like just one, but I'm no expert. Can anyone ID? I have more pictures if needed. Thanks!
  21. Newbie needing an ID

    Hello everyone, I’m a newbie to fossil hunting. I found this yesterday, my first time out since taking up this hobby. I found it along a creek in Shawnee, Kansas, USA. Some of the rock in the area had clearly been trucked in and some was from the area so I don’t know how this particular fossil arrived at the location. The fossil is about 28 mm in diameter. There are clear pores that are on the outside surface. Where it is broken, you can see the pores extending inside the specimen. My first thought is a coral or some kind but I’m not sure what kind. Any ideas? If you need any information, let me know.
  22. Marine? and mammal? fossils from a collection

    I recently acquired a large collection of fossils and I need help identifying them. #1 This was found along Charmouth beach in the pebbles so I don't know the geological age. #2 These are from Petersfield from a stream. Again, no idea of the age of it. #3 and #4 I don't know where these were found but I'm pretty sure they belonged to some sort of mammal.
  23. Fossilized Whale Bone?

    HI. I'm a rock hunter and found some fossils along the way but it's not my expertise. This may be a rock but I'll let the Forum decide. This piece is about 1 1/4" long by 3/4" wide and is blackish with a rust color interior on the broken end. I found it on the Dunedin Causeway, Florida and it resembles whale bone that I've found in the Venice Beach area, but it doesn't have the ocean tumbled shape. What do you think??? Thanks again, BronzViking
  24. Corsicana Bouillabaisse

    Buried in my prep bin I found a marl nodule from the Corsicana Formation that I snagged for the gastropod/bivalve association. Longing for the days before the site was built over, I pulled this thing out for prep. Well surprise, surprise! Beneath the Neithea bexarensis and Gyrodes rotundus was a Dakoticancer australis carapace completely hidden. I’m lucky I didn’t run my scribe through it while reducing matrix. The movable finger from the right chela is poking out from under the Neithea, but I opted not to blow apart the other fossils exploring for appendages. Anyway, it’ll keep.
  25. nj cretaceous id fang or tooth?
