I need some help with this little guy I found in the Peace River (FL). I have the darnedest time with ear bones - they all look alike to me. Has anyone seen one like this before? Is it marine or land critter? It seems well mineralized and measures about 30mm x 20mm. Any help would be appreciated. Thanks!

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

Picked up another inner ear bone last week that looks to me like it could be another parietobalaena, (baleen whale). I have had the good fortune to have two Id'd by @Boesse. One in 2019 and one just last month. In comparing it to the 2019 find I think it is a match. I am hoping the good Doctor has the time to provide an ID on this one. If anyone else has an idea as to an ID their input would be appreciated. Thanks! First up the 2019 find: Now the latest, found last week. It measures - 40mm x 37mm x 29mm or 1 9/16" x 1 1/2" x 1 1/8"

This has got to be something? Fou d in Utah - 1st on looks like VanGogh's Ear. The second a small loaf of bread. I don't know

Found this earbone this past week - have another just like it, but never got an ID. So hopefully this time around I can! It’s 1.2”/30mm long. @Shellseeker @diginupbones @Harry Pristis

Another find this weekend, actually Rick found it but let me bring it home, want to confirm that it's a petrosal and also what species based on my research I believe it to be. Found: Greensmill Run, Greenville NC among a huge array of items (whale bone including several tempanic bulla, shark teeth (great white, tiger,crow, Giant White Shark etc) and two Enchodus teeth etc. Believed to be a Petrosal from Balaenoptera Sursiplana? I thought (from one specific article/image reference below) that is was possibly Plesiobalaenoptera but it noted they are only found in Italy and the long flat part seemed much thicker than the reference image, but the rest seemed better matched than from the other species noted above?

East Venice, FL. Pleistocene material. I believe the fossil is a bulla It measures 76 mm x 41 mm at longest points. It is on the red color side. I am attaching a bulla that is black in color for comparison which is a smaller example. Can anyone explain which animal they could have come from?

After a lot of research and luck, I discovered that one of my finds a couple of weeks ago is an ear bone. Found in Nebraska but still not sure which critter it came from. I am tagging @Shellseeker and @Harry Pristis because I know that they were involved in some past ear bone discussions. The second photo is one that I found on the web from a site selling an ear bone that they claimed was from a woolly mammoth. Thanks

Hi, just going through some rocks I brought back from Norfolk, UK, thinking quite a few may be fossils (I didn't have long so just grabbed anything I thought looked suspiciously organic by intuition) and as it turns out I think I was quite correct in a number of cases - I think I have quite a few pieces of whale and and a few little bits of mammoth tooth. Trying to confirm this to myself led to a lot of reading and learning online about the local geological formations involved and also whale anatomy, both new topics for me which I always enjoy delving into - part of the enjoyment of fossil hunting for me - I'm less of someone looking for beautiful specimens for display (though I'm not going to turn those down!) and more someone who loves the detective work of trying to identify obscure parts and recreate some aspect of the vanished world before us from its traces. And searching through whale anatomy and what these weird chunks could be I came across a picture of a whale periotic and realised that the weird little pot structure I had was almost definitely one of these, which if I am correct is good because I believe they are one part of a fragmented whale anatomy that is quite diagnostic. Also I then realised that a strangely hooked piece I found right next to it could well be the tympanic! The preservation here is unusual because many theorise that these kind of whale fossils were first laid down in sandstone in the Miocene when Norfolk was covered with a shallow warm sea, and then later in the Pliocene and early Pleistocene when temperatures dropped sea levels dropped too and the area became land (part of the reason the geology of this area is interesting is the constant transgression and regression of the sea over a few million years), these Miocene rocks were eroded away and the harder fossils reworked into new estuarine or nearshore sediments of this era, often but not always with a layer of hard iron-rich concretion coating them which helped protect them (I guess one question would be, is there anyway of easily removing this hard concretion layer?) So if I am right, these are bones from Miocene whales (many showing signs of shark damage), reburied in the Pliocene / Early Pleistocene and then finally eroded out again in the modern day - quite a journey! Anyway, enough background, for starters I'd love to see what people think about this periotic / tympanic. Am I right? Here's a summary of my findings (note I used a pic of dolphin periotic someone posted here for comparison so I hope that isn't too cheeky)
