    Bird?

    My buddy found this on the beach in Florida. The fact that it's hollow makes me think it's a bird bone. Any ideas?

    Wood or bill/ beak/nail?

    Hello! Found in NW Alabama, Franklin county, near creek. Not sure if these are fossils, but there is a perfect hole near wide edge of the larger "half". Yes, the photos are of 2 peices that appear similar/same, as with the upper and lower bills/beaks of birds..Red Color from lighter can b seen in photos. Could it/they be from Native American adornment, or even much further back in time?? thanks! Chris

    Heron?

    Howdy all, Just purchased this avian coracoid. The seller claimed it was of Ardea herodias, and after comparing it to actual heron coracoids (using images on the web) I find this to he the case. However, I would like a second opinion. Size: 3 inches North Florida
  4. Here is plate with a big fish (sturgeon?) and a bird (unknow species, look like a cormorant!) from Liaoning Province, China. The bird even has its feathers preserved (if not painted). What do you think? Are they genuine? And what species if genuine?

    Bird outline with beak in a rock

    I found a split rock and it has the faint outline of a bird, but there is a piece of beak inside the rock. I am curious. Would anyone be able to tell me what it is? Thank you.
  7. This is a green Honeycreeper, half male half female. I did not know this existed in nature, quite fascinating. Included link to full article and video. https://petapixel.com/2023/12/14/rare-half-male-half-female-bird-is-photographed-in-once-in-century-event/

    Help ID’ing

    Hi all! New here and I’ve already spent hours down the rabbit hole. I’m a body piercer and jewelry professional but I love rockhounding. I live in Arkansas and we are know for our quartz. I collect rocks literally everywhere I go so I can’t say for certain where I picked this up. I put it in my tumbler with a load and I check the rocks often during the process. This was in the tumbler with first stage grit for about 2 days. When I was doing my routine check, this rock really stuck out to me. I swear I see a bird embryo. Not only that but it feels 3 dimensionally like a bird body. I know the pareidolia is real with my brain but I’m kind of obsessing at this point so I need someone to bust my bubble.

    Anyone know or have any ideas?

    Just wondered if anyone could tell me what they think of these pieces.
  10. I’m going through my collection of unknowns, and came across this little guy. It is a small, ornate vertebra collected from the Pliocene Yorktown Formation at the Lee Creek Mine in North Carolina,, USA. Scale in the photos for size. Bird? Snake? Other? thanks

    Bird wing bone
  12. This came into my email inbox just now. This bird looks very familiar to many of us.... https://cowboystatedaily.com/2023/11/06/rare-first-of-its-kind-wyoming-fossil-bird-donated-to-chicago-museum/?utm_source=Klaviyo&utm_medium=campaign&_kx=FNPCgSCz7FplU90B8_ouKgYat5AOYRhTA2s_dLpzjqBx2CdT-fhicfAJbOddWJMi.UXPtrV

    Prehistoric bird?

    Ancient bird like creature
  14. I've got a few bones that I've been scratching my head over for a couple days. They are from the Hell Creek Formation in Garfield County, Montana. They're extremely thin and hollow, and only one seems to have undergone some compression. I'm including measurements with the photos below. Curious to hear what you all think.
  15. Considering getting this guy, don’t have anything like it in my collection yet. Any red flags here? Sorry for not the greatest photos it’s behind a glass case.
  16. looks fake to me but maybe im wrong?
  17. Is this a genuine fossil bird from China?
  18. This is an Enantiornithes bird found at Liaoning of China. Note the chest region in which it looks like remnant of skin (and feathers around the body too). Also, there is a pair of long tail feathers. What do you think about its authenticity?

    Hastings Tooth and Claw?

    Hello, I wanted to ask about a couple fossils from the Hastings subgroup, Wealden supergroup, Wealden of Sussex. One is a tooth labeled Baryonyx and measures 0.4 cm. At that size I'm assuming this is just a tooth tip or from a juvenile? The other is a "theropod" claw measuring 0.7 cm. It's very tiny and has an odd protrusion on the underside towards the articulating end, which reminds me more of some bird claw cores. Is this even dinosaurian?

    Bird egg?

    Hello fossil lovers! Please accept my apology in advance, but here it comes: is this a fossilized bird/duck egg? It is too round to be a reptile egg and the white part looks like shell. The inside is crystallized. Sadly I can't provide provenance, as I bought this at an antique's shop from a deceased collector (for those who know him, it is from the collection of the writer of Bob Morane)... Doesn't look like just a concretion to me. Thank you for your time, have a good day!

    Is this a fossil foot?

    I found this near Logan utah, I have another “bone” fossil I found there that I would like to post also. A hater told me it was natural who looked at it in person. I just want to know. I am a proud rock hound. This seems odd to me. I found several horn coral fossils and sea life proof near by. This would have been near a lake bonneville shore at some point. The surrounding seems very sedimentary while the inside seems agatized. Following what looks to be an actual foot and not a print seems you can see the actual outline of how a toe was curled into the mud. There looks to be a total of 3 toes but doesn’t look to be all forward facing by Dino prints I’ve seen so maybe big bird or just the way it laid to rest. I need help please!

    Help with Santa Fe river fossils

    Here are a few things from a recent trip to the Santa Fe river that I was not able to identify. Guesses: A/B: Since these bones are hollow, does that mean they had to belong to a large bird? C/D: smaller bird bones? E: Mastodon or gomphothere tooth enamel? F: part of a tortoise foot or maybe a sesamoid bone? G: Translucent in the light, making me wonder if this is fossilized sap or something of the sort Appreciate any help!

    Could it be a fossil bird egg?

    Collected on a beach in Central California. The length is 6 cm.
  24. These two (partial) bones were collected two summers ago (2021) on private land in Weld County, Colorado. They’re from a super fossiliferous bit of exposure which, based on the Oreodont fauna, is likely to be part of the Poleslide Member, which dates to the early Oligocene. These bones have puzzled me since I collected them, and I had for quite a while hypothesized that they must be some sort of ungulate metatarsal. I decided to pull them out again tonight, and having more experience with osteology generally I have decided that these look decidedly avian - specifically, the proximal ends of a right tarsometatarsus. The White River Formation has a rather diverse formally described avifauna: Benton et al. (2015) lists six genera in five families along with several different morphologies of bird eggs in The White River Badlands: Geology and Paleontology, however only one family (the Bathornithidae) has more than one described genus. Bird fossils are well-documented from the WRF, and incidentally quite a few avian holotypes have been described from the White River Formation in Colorado, so perhaps the preservational bias favors them more in that general region. However, bird fossils are simply generally rare in the fossil record due to their delicate nature, so I thought I’d post on the forum before I make a (relatively) extraordinary claim. Now, these two bones aren’t in any way associated, but they’re the exact same sort of bone. They’re identical (with the exception of the shorter one being slightly larger) - same bone, same taxon (as far as I can tell, the shorter one has some weathering). This is what puts me off even more - what are the odds that not only did I come across bird fossils, but that I independently found the exact same end of the exact same bone from the exact same avian taxon in the same week? Tarsometatarsus bones do seem to be a fairly commonly preserved isolated element for fossil birds, many genera are described based of a single tarsometatarsus and the same summer I found these I happened to find an avian tarsometatarsus in the Hell Creek Formation. But it would still be odd. Here are the pictures: I should also add that these bones are in fact thin-walled and hollow, though getting the camera to focus on the broken ends is difficult. But that doesn’t automatically make them avian, bones are fairly frequently hollowed out by simple decay. Below is an image from Benton et al. (2015), with an illustration of the holotype tarsometatarsus of Badistornis aramus, an extinct relative of the living limpkin, for comparison: My bones actually compare quite well to this illustration, though there are differences so I wouldn’t assign them to this genus/species even if I could confirm that they are bird tarsometatarsi. I also don’t think that they’re Bathornithid bones, even though those are the most famous birds from this rock unit. Of the genera from the WRF only Bathornis has a known tarsometatarsus, and it’s both morphologically very different and much larger than my bones. I’ve also ruled out the Galliformes and Falconiformes (two bird orders with representatives in the WRF), again assuming these are avian bones. I think that it compares best with wading birds such as herons and, indeed, limpkins. But this is mostly informed speculation I admit. So does anyone have any thoughts? Is there a more obvious answer for what this bone could be, or does it truly have avian affinities in your opinion? Looking forward to hearing everyone’s thoughts. References: Benton, R.
