I found this Saturday here in SE Texas on a river gravel bank... it's a skull piece with an ear bone... an inner ear bone. Periotic... petrosal? Not big enough for the big mammals I think... so horse, bison, cow? Thoughts appreciated.

Hey Gang, Happy New Year! I'm not sure this is exactly a fossil prep question but it relates to Identifying an unknown supposed Pleistocene fossil from Iowa so here goes. I'm trying to put together a comparative collection of extant/extinct mammal inner ear bones. I've got a number of fossil fragments from a number of critters and about to work on removing a couple of petrous bones/bulla (highlighted with red arrows) from a couple of extant skulls. Ive got to cut them out of 2 extant bovid skulls/cap--see photo below: The smaller example on the left is from a sheep and the other a much larger bovid I'm assuming a cow/Bos. I am thinking I can take my dremel with a cutting bit and remove the sheep petrous bone fairly easily by removing a surrounding section thru the skull cap along the blue line i've drawn. The larger skull on the right is more stout so I'm looking for any easy/cheap ideas from Harbour freight, hacksaw ideas or other to cut the ear bones free. Perhaps the dremel will have no problem cutting thru it as well. i've seen some pretty cool dissection equipment but I'm doing this on the cheap to satisfy the curiousity of how these bones are positioned/attached and identify their components and take some photos along the way. Any simple solutions for removal are welcomed. I'm ok with up/experimenting one side as I can always work on the opposite petrosal of each. Here's an unknown petrosal that I have that I want to compare against to compare the two extant bones too. I was told it might be possibly bison from the Pleistocene of Iowa. That ID has not been confirmed Thanks! Regards, Chris

For my last hunt of 2023 I got back out to the Calvert cliffs, launching my kayak a little after sunrise I made right to the beach. The water was still a little high when I arrived (I feel like it’s been higher on average this year) but I found a nice shark vertebrae and a 1.62” hastalis before low tide. Finding a few smaller teeth for most of the walk, I then at the end of the beach where I normally turn around found a nice epiphysis disk, sitting out in the water. Now for my walk back the water was nice and low, and freshly washed out, sitting on the water line was a gorgeous 1.78” Megalodon! The root is starting to wear, but the blade is perfect, great serrations, tip and all! Continuing back I find a nice tympanic bulla (whale ear bone) my first on this beach. Last but not least as I return to my kayak, sitting about two feet away is an amazing upper cow shark tooth! A lot of variety for the day in addition to the normal shark teeth finds, another great trip and a great way to end the year! Thanks for reading, see y’all next year!

Despite not really feeling up to hunting yesterday (I'm getting discouraged by my finds lately), I decided to go while the weather was still decent. And when you are not expecting to find much and/or set the bar pretty low, it makes it easy to exceed your expectations and have a pretty good trip. Here is what I brought home: First up are the odontocete fossils: My first ear bone ever: And a vert and related piece of bone that were sitting together under an uprooted tree: That's it for cetaceans, but that is pretty good for one trip for me. Other verts (not in good shape, though): Burrfish mouth plates (also not good condition): Ray mouth plate pieces and my biggest tail barb so far: Random osteoderms and bone pieces (I keep less than half of the bones I find): Various steinkerns, which I try to limit now as well, but the spiraling ones are cool: Gator tooth that was still partially in matrix: Fish jaw with teeth (maybe...let me know if you recognize it): Crab claw, I think: What I believe is my first piece of petrified wood here (again, feel free to correct me): And, of course, shark teeth: My best Great White so far: My first Angel shark tooth (shoulder and tip of crown are broken): A cool looking tooth - posterior sand tiger I believe: And the rest of the teeth (including a couple broken threshers, a barracuda, a sawfish/sawskate, etc.), which I won't show individually: As always, I wish my body could have handled a few more hours of hunting, but between little rain (no new wash-out), low creek water levels, rising heat, and health limitations, I think it turned out to be a pretty good haul. And no speeding ticket this trip! Thanks for reading!

As I was rummaging through my accumulated fossils, I found this whale otic bulla. It has an unusual appearance, and had a tiny bit of adherent limestone. I think it may be of the Late Oligocene Suwannee Limestone in North Florida. Can someone here identify this bulla? @Boesse

Hi All! I am a newbie & amateur, making my very first post. I picked this up whilst searching for sharks teeth along the beach. I am a very curious being and this is just a mystery to me. Any help or advice is greatly appreciated! Thanks again!!!

Is this a whale ear bone? Age: Miocene Loc: Poland

Here's a land mammal petrosal that I've just retrieved from storage. It's from the Santa Fe River, so it's Pliocene or later. It appears to be complete. These petrosals all look about the same to me. Help me out here.

Found this little fossil on the James River shoreline near Surry, Virginia (US). Wondered whether it might be an incomplete dolphin ear bone, but not entirely confident in that ID! It's just about an inch long.

Here’s another find from today I need an ID on - I’m almost positive it’s an ear bone, and a periotic at that - but I’m not sure if it’s deformed, worn away/broken, or just not cetacean, so once again - any help is appreciated! @Shellseeker @Boesse

Yesterday I was in a creek that I haven't been to in a while. I got the normal fossils, mainly shark teeth and the occasional meg frag or mako, but I also got these strange fossils that I have never seen before. The first one reminds me of a dolphin ear bone we got earlier this year, so I was wandering if it was some sort of ear bone. The second fossil I am very curious about. At first I thought fossil barnacle, but it appears to have enamel on top. The closest thing I could compare it to was a stingray dermal plate I saw in a book, but the bottom of mine seems more raised and the top seems less slanted. My only other guess would be fish tooth, but the flat bottom turns me away. any help is appreciated, thank you!

Hi guys, I found this bone cluster on the shore of the Black Sea, near the city of Balchik, Bulgaria. From the region there have been findings of Miocene cetaceans, seals and some ground megafauna. The more circular bone somewhat reminds me of an ear bone but comparing it with pictures of fossil dolphin ear bones I can't say if it really is one. So my question is if it is an ear bone and if it is, does that mean that´s a part of a skull? Any help on the identification of the fossil will be very much appreciated! Best regards!

I found this petrosal on a South Carolina beach near Charleston. I would love to know the animal it belonged to. Is it cetacean @Boesse by any chance? Thanks for looking. Scale is CM.

Here is an odd shaped bone that I think could possibly be an inner ear bone. It is nearly .5 inches long and .25 inches wide. What do you think it is? Any guess on what size/type of animal? It was found on a beach near Jensen, Florida. Thanks much for all your help.

Never seen fossil in my dig sites. Inland Venice, FL. Reddish tint. Longest length is 48mm. Width 33mm. Material from this site has Equus and Sloth fossils. I did find a "whale tooth" within 50 feet of this fossil. I have recovered other whale ear bones that did not look like this one. Thank you in advance for your ID assistance. Regards, Michael

Hello all! Sorry for the not-so-great photos here. My phone camera is... kind of a fossil. I found this mystery fossil on the beach in North Carolina, USA, somewhere near Emerald Isle if I'm recalling correctly. My best guess is that it's a periotic bone from a dolphin, porpoise, or something of the like, but it doesn't totally match up with images I've seen. I've also considered that it could be a ballast bone, but again, hard to confirm via Google search. Any thoughts would be appreciated!

I have spent many hours on this forum, but this is the first time I am posting because this inner ear bone has me completely stumped. It is the first inner ear bone I have found, and it appears to be the periotic of a small/medium cetacean. I see strong similarities with some dolphins and pygmy sperm whale specimens also pulled from the Peace River in Arcadia, FL, but none that really match up. I am new to identifying anything beyond teeth, but I was excited to find this and would love to have a better idea of what animal it is from.

I found this in a creek in the Charleston, South Carolina area where I often find sharks teeth and whale bones. I believe the site is Oligocene/Pliocene. If found anywhere else, I would have assumed it was a piece of gravel and tossed it, but it does look a little strange. Perhaps someone with more experience in the Cenozoic can help with the ID. The item is about 3 inches at its longest dimension. Like I said, I am thinking tumbled gravel on this one, but figured that I would check before throwing it in the garden.
