I'm an invertebrate guy. When I split Devonian bedrock and find a trilobite It's pretty definite that I've found a Devonian trilobite. Now that I live in Florida, things are not quite as clear. During a walk on a NE Florida beach yesterday I came across a bone. I'm not an anatomist, but it looks like a bird's humerus. It is not heavy. It doesn't feel mineralized. It is hollow. Could this be from a prehistoric bird or just trash from a recent beach picnic? To be a fossil, something doesn't have to be mineralized. It could still contain some organic compounds. So.......what do you think? Thanks. Tom

First bone is modern from Trinity river so this for the sake of learning, assuming it is a Tarsometatarsus, my question is how can you tell if bone is from waterfowl and how hard to determine bird species? The dark bone is from Cretaceous Woodbine and I'm not familiar with preservation on them, this one is funky, scratch it with fingernail and it's powdery, might be modern and hoping it's not too worn for ID. Thanks for help!

Found an interesting fossil in my Nat Geo fossil and gemstone kit. Looks like the head of a bird, lizard, or maybe even a tiny dinosaur. Location unknown. US Quarter for scale. Fossil learning guide doesn't say anything about this fossil. Please help identify.

I am just going through some miscellaneous pieces that I have in my collection. I received these 3 pieces from my fossil mentor Walter Lietz, about 30 years ago, he received them in a trade with a fossil dealer from California named Judy Owyang. I met Ms. Owyang a couple of times when she would come up to the Chicagoland area and meet at Walter’s house. All 3 pieces are to have come from Maricopa Brea and are supposed to be bird fossils. I was wondering if someone knows what type of bird the claw belongs too, it looks like a raptor to me. This next piece is supposed to be a bird foot bone. This last piece is supposed to be a bird neck Vert. Any help would be appreciated.

Hi everyone! I found this claw while anthill hunting on the White River formation of northeastern Colorado. It's about 6 mm in length and 4 mm tall. Honestly I'm not certain that it's a fossil, but if it is I'm really excited to have found it. My first guess is that it's a small bird, but it could very well be mammalian or reptilian. Any input is appreciated.

Found in the Trinity River near the intersection of rt.157 and Green Oaks Blvd., Arlington TX. The default identification is likely large modern bird. Perhaps a humerus ? I thought it worth posting just in case someone should be able to offer hope that it is a fossil, however.

From the album: Hell Creek / Lance Formations
Avisaurus cf. archibaldi Hell Creek Fm., Garfield Co., MT, USA More information Avisaurus is an extinct, toothed Enantiornithine bird that lived at the very end of the Cretaceous. It likely held a similar niche that hawks/eagles do today, preying on small vertebrates like lizards and mammals. -
This is another fossil I found in a box at my grandfather’s house labeled fossils. Not sure what it is or where it came from.

Rooted mosasaur tooth morocco + bird bone
Jurassicz1 posted a topic in Is It Real? How to Recognize Fossil Fabrications
This is a rooted Liodon anceps mosasaur tooth from morocco and a bird bone from morocco. The mosasaur tooth is from a trusted seller that I have bought from before. But the bird is from a different seller. So is the mosasaur tooth real and is the bird bone also real?

Hey I recently got offered a fossil bird (Enantiornithes, but don’t know the exact species) and wanted to see what you guys think about it. The seller said the bones and feathers are 100% natural. It has no restoration, but repairs to the matrix and reinforcement to the back of the matrix. Seller is a reliable and I’ve purchased from him before. Just wanted to double check as i don’t know much about bird fossils IMG_0659.MOV

Hello Am I right that these are bird teeth? Yixian, China, Jehol Biota. Dawangzhangzi Bed. I have looked at pictures of Hell Creek bird teeth and they have a similar, triangular shape and two points at the bottom, which makes me think bird. Though, at almost 1cm it seems large for a bird tooth. From what I can see, Yixian birds are much smaller. And this tooth is even larger than Avisaurus. If not a bird, could it be a fish? Though, again nothing described seems to fit.

My sun found this in the mountains, in Aragon, Spain on a mountain by accidence, while playing. It looks like a little bird, we can see a print of little feathers. But the skeleton doesn't really look like the ones we found online. Who can help us? We are curieus.

From the album: Lance fm. Microsite Finds
I found this tooth while looking through matrix from a productive conglomerate site while at home. At first I had no clue what it could be, but the consensus on its ID thread was that likely belonged to Avisaurus. While its hard to conceptualize birds with teeth from our modern perspective, that was the norm for many genera in the Cretaceous. Glad to have found this one and recognize it as a tooth. -
Skull length around 10 inches, skull width around 4-5 inches, with a beak that seems to indicate that it's a fish-eating bird. Any help would be much appreciated!

Hello, Thoughts on this? It intrigued me because I don't see Cretaceous bird fossils for sale often and would be a nice, unusual addition. The only bird I see listed as from Judith River is Hesperornis. But the only picture really I can find of Hesperornis limbs, the bones look much too fat and too thick. It is listed as a bird limb bone, from Judith River Formation. Seller gave me quite specific location info in a message -- 20 miles South of the Canada border, on the edges of Milk River escarpment, Hill County, Montana. On a layer where Hadrosaurid fossils have been found by the seller. Thanks for the help

Hello, any thoughts on this? It is sold as pterosaur remains--jaw pieces and a vertebra, from Ouled Abdoun Basin, Morocco. From the Cretaceous--unfortunately from an old German collection, so the information is limited. 240mm x 105mm Now, I think it is misidentified and is actually a bird--possibly Dasornis because on the first pic, the jaw has a long tooth and then a few of the smaller mini "teeth" which matches a drawing I found in a paper of similar birds, which I've also attached. If it's Dasornis or a bird, then that would mean it isn't Cretaceous in age? The preservation seems odd to me though---Most bird fossils I see from Ouled Abdoun, the bones are much lighter in color. Any thoughts would be great. Thanks

Hi folks, I've found this object which, to my untrained eye, looks just like small unhatched bird. Would like to here your opinions! I've found it in my garden (NL)... I can post more and better pictures here later, for now I hope the image below suffices.

I have a hard time telling if bones are fossils unless they are stone or fresh enough to scrape easily. Any help would be appreciated in learning this. Didn't take pic of end but it's hollow.

I found this tiny, slender bone at a Hell Creek microsite during my trip to the Dakotas in 2019 with PaleoProspectors. I'm not sure what it came from, but I'm hoping it's theropod, avian or otherwise. It's missing a section of the outer layer of bone and I believe the interior is hollow & filled in with the ironstone common in the formation. The dimensions are 1.7 cm in length and about 3 mm in width. I would appreciate any feedback you may have. In situ shot from the site: The closeup shots did not come out exactly how I wanted them lighting and detail wise. If you would like me to retake them or get different angles I'll happily do so.

I found a couple of interesting fossil bones yesterday along the Calvert Cliffs (Miocene exposure) in Maryland. Any ideas to what these belonged? #1 - My guess is this one is a bird bone. It's smooth (inside and out) and hollow all the way through to the closed end. If this is from a bird, do you know what type of bone it is (anatomically)? And any thoughts on what type of bird it might be from? I realize that isolated and broken bones can't usually be identified too specifically, but this seems fairly large, so I'm wondering if there might be good candidates for type of bird. #2 - This spike-shaped/pointy bone is also at least partially hollow inside, though the walls of the bone are thicker/more robust than the one above. I'm not sure if the central cavity goes all the way through. I've only been able to confirm that it's a few centimeters deep, just past the longitudinal holes/borings on the outside of the bone; however, I think the cavity may extend further but is filled in with matrix (I don't have the tools handy at the moment to clean more of this out). Speaking of those holes on the outside, they're irregular/asymmetrical, and I'm guessing they're post-mortem invertebrate borings. As can be seen in the two photos on the bottom left there are two grooves on opposite sides that run the length of the bone--one of these is more distinct than the other, though the one on the other side might just be more worn. I haven't a clue what this one is, and would love to hear your thoughts!

Hi everyone! Last week I found this nice, rather big, bird bone on the Zandmotor (Netherlands). It is most likely late Pleistocene in Age (Weichselian) but could possibly be older (though I doubt this is any older than early Pleistocene, given the conservation). I believe it to be a femur of a rather large species of bird. My first thought was the great auk, Pinguinus impennis, but I think my bone is probably not sturdy/thick enough for such a heavy bird. I'm currently thinking it might be something like a large sea gull, but this is just guess work, and birds are definitely not my area of expertise. What do you guys think it might be? Also, if any of you has some kind of free identification guide/paper for bird bones (modern/fossil), could you please share it? I'll already tag @Auspex and @MarcoSr as I remember that you two have worked with bird bones before Thanks in advance for your help! Max
