    HELP ID PLEASE and THANK YOU

    This was found in a dried up creek bed in Arizona, near Tombstone, Arizona. At first I seen the crystals sparkling and thought, "cool an old 'Hag Stone'. ...in the desert???" On further inspection it kind of has a distinct shape. Also the hole look much like sinuses in a skull, possibly bird.
  3. I had the fantastic luck to find a 2" Otodus obliquus both of my last two trips out, one of which with a neat little pathology. The 2" striatolamia was another outsatnding find, I can still count on my fingers the number of teeth this size I've found in the Aquia Formation. Thanks for looking and happy hunting! .

    Can anyone help identify?

    I was hoping someone can help me identify? Rocks, not myself.

    ID help please

    Texas Gulf Coast finds. Rollover Pass, Galveston. What is the age of the specimens? What is the yellow stuff?
  9. Hello! I’m a new member but I have checked the forum many times to identify my fossils and shark teeth. Usually I’m up by Calvert cliffs Maryland but recently I found a nice tooth at Jupiter beach in Florida, if anyone has any ideas on what type it is that would be awesome! Im still new to fossil hunting and identifying!
  10. I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!
  11. I would like to share a beautiful and possibly important crinoid in my collection from the Pennsylvanian Holdenville Formation of Oklahoma, USA. This specimen is best identified as Plaxocrinus sp. aff. P. dornickensis as originally described by Harrell Strimple in his 1961 paper "Late Desmoinesian crinoid faunule from Oklahoma", and confirmed by Pennsylvanian crinoid expert Peter Holterhoff. It was prepared masterfully by Mike Meacher. It is a member of the family "Pirasocrinidae", which is a prevalent group of crinoids especially in the Pennsylvanian. They are characterized by a low, saucer-shaped cup with three anal plates, axillary first primibrachials and various spinosity on the arms, and most notably a prominent highly-specialized "umbrella-like" anal sac that terminates as a platform of plates surrounded by a circlet of laterally-projecting spines. Aside from simply wanting to show off one of my favorite fossils, there are a couple of reasons I think sharing this publicly could be useful. First off, articulated pirasocrinids are generally very rare in the fossil record, especially of this genus. It is thought that these crinoids had weak sutures between plates which made them highly-vulnerable to disarticulation. The vast majority of remains are found as loose anal/brachial spines and occasional calyxes, as shown below. https://snr.unl.edu/data/geologysoils/fossils/nebrinverthughes.aspx Likely because of this, formal descriptions and pictures of pirasocrinid crowns are scarce in the literature and it is difficult to find public references on what articulated specimens look like, especially of how the spines of the arms and anal sac are configured. Though on my specimen the arms are not 100% complete all-around, enough is preserved to describe the full structure of the arms and the nature of the spinose primibrachials. Moreover, the exceptionally-preserved and prepared anal sac shows nearly the full extent of its articulation. Note the couple of near-complete brachial and anal sac spines, whose extraordinary lengths exceed the width of the calyx. The second reason this specimen could be important is more specific. In Strimple 1961, Plaxocrinus sp. aff. P. dornickensis was described on just a single specimen; the calyx shown below: Atypically for the genus, this calyx has a very smooth outline owing to flat, non-bulbous basals and nonimpressed, almost imperceptible sutures. Strimple concluded this species to be closely-related to but not conspecific with true Plaxocrinus dornickensis (which is a slightly older species than the Holdenville fauna, according to Dr. Holterhoff); hence the "aff." in the identification. Essentially, as far as formal description in the literature is concerned, the full crown of this crinoid is unknown. I have also not personally seen any other confirmed crowns of this species from the Holdenville Formation. All-in-all, this specimen could be quite significant for showing the previously-unknown arms and anal sac of Plaxocrinus sp. aff. P. dornickensis on an articulated crown, which might help further its description.

    New member... old fossils

    Hello, New member who is discovering a love of fossil hunting. All of my collection comes from a large creek on our property in NE Ohio. Please check out the star fish, and possible bird track.....and comment if anyone can identify the last rib looking fossil I attached. Thanks!!
  13. I believe I have made quite well with collecting Moroccan mosasaurs, so I wish to set my eyes for new goals. And first US mosasaur material is already heading its way. I have been hoping to learn more about American mosasaurs in general and also basic tooth characteristic of more common species. Only one Im relatively familiar with is Tylosaurus proriger. With Platecarpus tympaniticus only by few articles. I managed to find information about most formations where material seem to come from, but not Ozan fm. What species were present besides Tylosaurus proriger? Thanks for replies.

    Andalusia, AL vertebrae

    Hi all! I made a journey down to Point A Dam today (despite high river levels) just to shuffle about. I came across these two vertebra, the smallest of which is clearly a fish, but I’m not quite sure what the other is. Cetacean? If you have any info on either, please share. Thank you! P.S. I somehow never have a ruler with me so I used the lines of a college ruled notebook, which are separated by 7.1 mm, as a makeshift scale. I apologize for this. 1: 2:

    Coastal Find

    Good morning all! I've had this potential fossil for a number of years, but am uncertain of it's origin as it was sold to me by a roommate for pizza money. He didn't remember the exact location he found it, but said it was from a beach in the south east. Potentially Alabama, Florida, Georgia or the Carolinas. He gave me a long bone and what appears to be a flat bone chunk that were found in the same area, but that may not be from the same creature. I had these pictures already with a lighter for scale, but can take pictures with a ruler when I get home from work. I've done a lot of googling, but as I'm an amateur I don't know that I can draw any real conclusions. Excited to hear what others think and if it confirms what I suspect!

    Hell Creek Tooth ID

    2.7mm long “raptor” tooth found in Garfield County, Montana. Isn’t curved and has serrations. Possibly enat tooth.
  17. Hello! I have been fossil hunting for quite a bit now and this is my first ever (what appears to me at least) fossilized bone! I would love just a general direction on what kind of animal it could’ve been- I know this area is very well-known for marine fossils, so of course my first thought would be some find of fish bone? Or I could be totally wrong, and it could be a more recent mammal! Any insight is so much appreciated- all I want to do is expand my knowledge. Thank you!

    Please help me identify!

    I have had this fossil that I always thought it was an egg . I have thought it might be something more and have kept it for over 20 years. The outside is like a clay matter when holding it leaves a moisture spot of your handprint on outside. It has cracked so you can see what’s somewhat inside of fossil it was always like that. On the other side, you see a bone sticking out on the bottom. I brought it to a couple fossil shows around me, but it has no identification of what it could be. It’s something. They told me my best shot would be to get it scanned because I should not cut it.

    Bones - Old Orchard Beach, Maine

    Curious about these - and they may not be fossils (more modern), but the color of them intrigued me as they are not white. These were washed up on the beach after a storm and I think are associated as they were found in the same general area. They have similar features, and maybe are the same type of bone with different levels of wear? They were found on the beach near where the Goosfare Brook empties out in the the Atlantic Ocean. 43°29'42.0"N 70°23'04.8"W Thoughts?
