  1. Gastropods seem to be quite rare in the tracts of the Bearpaw formation I'm familiar with, so I'm incredibly curious about this lone specimen, the only one I've found. I found it in a hard layer of small conglomerated bivalves, pteria linguiformis, I believe, in sandstone dating roughly to the Campanian-Maastrichtian border. The specimen was collected from the western half of Diefenbaker Lake in southern Saskatchewan. Anyway, here are the photos. If more angles are needed please let me know: Pteria linguiformis (?), which constituted the conglomerate: Thanks for your time.
  2. Mini Miocene Marine Mammal

    I found this a few days ago along the Virginia side of the Potomac River along a miocene cliff. It's mostly if not all Choptank formation. Any ideas about a genus? Grid is in inches. Looks like maybe mature dolphin tailbone, but it's so small???
  3. Mystery Scapula

    I found this scapula this weekend along the Potomac River in Virginia. It's a vertebrate. That's all I know for sure. Most of the cliff next to the beach where I found it is miocene marine, but the very top is pleistocene terrestrial. The grid is in inches.
  4. I really have no idea what this is. Maybe I am missing something obvious. Maybe a nautiloid fragment? It was found in a fossil-rich hard miocene(I think) sand/mud stone. In the that piece of rock were some poorly preserved bivalve and gastropods. Lastly, what would cause those interesting markings on it? The NZ $1 coin is has a diameter of 23mm Thanks!
  5. Marine Fossil ID?

    I found this is Western Washington state in an Oligocene Era sediment. I was thinking baculite but I have no idea. Someone please help me out. I split open a huge piece of mudstone and it popped out negative and positive (so the rock on the left is the imprint and the right is the positive). A piece broke off so I had to glue it back together
  6. No idea about what this is.

    Recently re discovered a bunch of these things that we got from the Canary Islands. They were all washed up on the beaches and they do not look stricktly geological to me and looks kind of like some kind of modern calcified organism or trace of one. I stumbled upon a book at some point, I believe it was called Darwin's Fossils that said these were some kind of remains of algae that have fossilized, but when I looked that up there was no evidence I could find supporting this claim, maybe someone else knows what these things could be? Any new insight is appreciated, Thank you.
  7. Requesting assistance identifying the dark slug-looking forms, these look like they were once soft-bodied so I'm pretty lost. I haven't the foggiest idea what these are and my fossil reference books don't have anything that looks like this in the photos or illustrations from what I can see. This was a creek find in southeast Louisiana. Your time and expertise are very much appreciated by this fossil newbie, thanks.
  8. Couple of finds

    I think I may have found my first Devonian bryozoan. (From Sylvania, Ohio.) And I also am not sure if these are shell or plant impressions. The rock that I think has the bryozoan has many nifty whatnots to explore, but that pattern immediately caught my eye. I'm not sure if the fan shape on the second rock is plant or shell. And there's a small bit to the left of it that appears to be shell that I haven't started to ID yet. (Pics in second post) Thanks for any help.
  9. This comes from Centerville Beach, Humboldt County California. I've found alot bivalves and snails in the cliffs where I found this. Another Formation 5 miles away has had reports of turtles, shark and marine mammal teeth and even agatized whale bones. I'm sorry about the quality of the pictures. I do not currently have a very nice camera. Its sticks to my tongue and has a rough porous surface. The divet on the right side of the bone in the first picture is a place where is has apparently broken.
  10. Clearing some brush under an old red oak and found these
  11. Small Jaw

    I found this little specimen that I assume is a jaw section a while back when sieving through some matrix. The material that it came from is marine from the toolebuc formation in central Queensland Australia this is cretaceous albian in age. Any input I would be grateful for. The specimen is 4mm on the long so quite small Regards Mike
  12. Near the Dutch town of Winterswijk is an Eldorado for fossil lovers. A student has now analyzed pieces from museums and (primarily) private collections for his master's thesis. He found an amazing amount of almost completely preserved skeletons, between 242 and 247 million years old. The good condition is presumably due to particularly favorable development conditions. LINK
  13. Hi there, I'm wondering if anyone can help me identify what this belongs too? Location is morocco which we all know can be risky, however it doesn't look like a typical fake to me. Not my expertise but would like to know an ID for it? Please see bottom image! Typical Fake Is it real? What does it belong too? Thanks in advance
  14. Keichousaurus

    Hello I am letting go my Keichousaurus fossil for trade, size it's at 9 inch and looking for dinosaur fossils or nice Megalodon tooth for it.
  15. I found this last year on the Yorkshire Coast. It was just sitting ontop of a large chunk of shale that had come down. Just prepped it today and it's come out pretty well. It's very fragile though. Will be from a ichthyosaur, plesiosaur or large fish!
  16. I found this unusual finger-like fossil on a Tampa Bay beach in Florida. It's about 3 inches long by 1 1/4 inch wide. It has an oval indention with swirls on the end, that looks like an external bivalve mold. The finger-like piece has corallite markings on it. Is this a mold of a shell or a fossilized coral finger? Thanks!
  17. Mysterious sea tooth

    I have found this thing in a campanian marine phosphate deposit. It came along with fish and shark teeth. It looks like some kind of tooth, but I have no idea. The brown area is translucent and looks like enamel. Although the grey is thicker and sharp. Any experts on cretaceous fish would be welcome Ps. This is definately not just a rock, I am fairly familiar with this deposit and can judge a rock from a fossil. Could anybody I'd this please?
  18. I feel clammy

    Misaki_cretacjapasiaet_misakcommensmollusal-2014-Palaeontology.pdf COMMENSAL ANOMIID BIVALVES ON LATE CRETACEOUS HETEROMORPH AMMONITES FROM SOUTH-WEST JAPAN AKIHIRO MISAKI, HARUYOSHi MAEDA, TARO KUMAGAE and MASAHIRO ICHIDA Palaeontology, Vol. 57, Part 1, 2014, pp. 77–95 "Lagerstatt" is not among the keywords,but some ammonites are reasonably well preserved A long while back I said here that syn-vivo encrustation might be more common in the fossil record than usually assumed . @Heteromorph
  19. Pennsylvanian unknowns

    Pittsburgh county Oklahoma USA, Pennsylvanian period , found in association with shark denticles and small ammonites. About 8mm across.Asking for a friend.
  20. Happy holidays everyone. I would greatly appreciate help identifying the following specimen. It was collected in the Santa Susana Mountains of Simi Valley, Ventura County, California. It came from the Saugus or Pico Formation. Saugus is late Pleistocene to late Pliocene while Pico is middle Pleistocene to Pliocene. My uncertainty regarding the exact formation arises from the fact that (1) it was float material already weathered out of the formation it came from and (2) based on limited research and knowledge, I believe there has been a lack of consenus regarding differentiation of the two formations (see recent work by Richard Squires et al. in Valencia and R. Squires in Newhall). I assume it is marine since all of Pico is marine and Saugus is non-marine to marine. At first I thought it was a shark tooth when I picked it up but I threw that thought out the window when I realized it had three serrated edges. Measures 22 millimeters long and 6.5 millimeters wide. It is 4 millimeters tall on one end and 9.5 millimeters tall on he end that has the needle structure. There are three to four 'bumps' on both long sides on the end with the needle. The bumps look evenly spaced. I can and will do my best to provide additional info if needed.
  21. Unknown marine fossils

    During a trip I purchased a container of small marine fossils. I could identify almost all of them except for a few. Age, location, etc. unknown. Does anyone know what they could be? P.S. feel free to ask for more pictures.
  22. Fossil? Funny rock?

    Hi everyone! What about this one? It was found in a well-known fossil site, an old cretaceous sea, in central Spain (Maranchón, Guadalajara, Spain). I would say the texture suggests a living creature of some kind. Too bad it would be a small fragment.
  23. Virginia Miocene 10/21/18

    After an extremely successful and enjoyable first trip to the Miocene of Virginia, my dad and I decided to give it another go when we saw that another guided trip was being held in late October. Our first trip resulted in my two biggest teeth ever, massive mako and huge hastalis. This time around, there weren't as many people on the trip, which is typically a good sign because it means less competition. The conditions, however, were brutal. It was very cold, and on top of that there were extremely fast gusting winds that made the river look more like an angry sea. Luckily, the tide was remarkably low while we were there, so there was a TON of ground to cover. I ventured south in search of some large shark teeth, and was successful to an extent. I talked with a woman who showed me a decent meg she had just found, but that was just about the best find I saw all day. Although I didn't come away with anything spectacular this time, I still got a respectable haul consisting of lots of hemis, some decent makos, a couple massive Chesapectan, and more of the typical Miocene finds. A big thank you to @SailingAlongToo again, for his instrumental role in organizing and supervising the trip. Already can't wait to head out again. I know there's a meg out there somewhere with my name on it. I'll find it one of these days. Thanks for reading! ~David
  24. I spent a few hours fossil hunting on two separate trips on Forest Service land in Montana. The first trip was this past spring looking for Late Oligocene - Early Micoene flora about 90 minutes outside of Missoula. The second trip was during at stint over the summer at a fire lookout tower in the Flathead where I spent just a few hours one morning looking at Devonian and Mississippian marine layers. Besides the obvious, the trips were quite different. The spring trip was a drive to a road cut on a Forest Service road while the summer trip was a seven mile hike in. Additionally the medium is completely different; flakey, brittle shale compared with big, blocky limestone. You can keep non-vertebrate fossils as long as you don't plan to sell them. Prior to heading to an area, I look through publicly available research, lectures, field trips, etc. to find possible localities. I only found limited information on possible identification of the Late Oligocene - Early Micoene flora and most of if was unpublished graduate work from a nearby site with only some overlap on species. Please feel free to correct any id's or throw new ones out! I believe these are cercocarpus, a mahogany.
  25. Hey folks, I was wondering how you guys would approach something like this (or if samples like this are even worth your time!) There's so much going on I'm a little confused as to how and where to start. would you remove the gastropods individually, break the rock apart, sacrifice the broken ones in the search for more complete specimens, leave it as is? I went through the pinned messages and learned a lot, but was curious if anyone's come across similar types of rock and could give some insight. My goal is to hopefully find and extract some of the more complete specimens, and maybe discover some trilobites along the way! The plan was to chisel out as many surface fossils as possible, then strike the rocks with a sledge hammer to break up the pieces, give them a good hard scrubbing, then use my steel picks and chisels to poke around further however the resources provided to me by @FossilDAWG and @Kane (thanks again by the way!) described a number of rare, some now lost, trilobite specices from the same formation found in similar contexts alongside Ceratopea Canadensis, so maybe a lighter touch might be in order? I'm still a little scarred from the time I put a pickaxe right through an almost complete piece of 1st century terra sigillata once upon a dig </3 I'll definitely be looking into air pens/compressors (looking at you ME-9100) as well, but on my pay that's one of those 'somewhere down the line' sorts of purchases. If those are definitely the way to go however, I can always shelve these for that later day...they've been sitting around in a forest for this long, another few months wont hurt! I did notice while cleaning the sample below that there appeared to be two separate matrices, a softer one which I assume was the sand/silt and then the hard dark rock underneath. I've got a much bigger slab with a lot more going on, but I grabbed this little one to practice and learn on! My first target is that crystallized one which is slightly exposed on the top (bottom center of the picture on the right) followed by whatever that is beside it and that mussel looking fellow.
