I just finished up preparation on this amazing Oligocene dolphin. It is from the Ashley formation and is a real beauty. I made the decision not to completely remove it from the matrix, as I believe it is more aesthetic this way.. It was missing the last 3 inches of the pre-maxilla so that had to be restored but we did find a few other teeth in the matrix.

Had a beautiful day hunting the Peace River, FL yesterday and came away with some intriguing finds. From prior postings and photos I reviewed provided by @Harry Pristis and @Shellseeker I believe the first exciting find of the day was a small whale tooth and I am seeking confirmation on that here. The tooth measures 37 mm x 10 mm and I believe it shows the hint of the ring pattern referenced by Shellseeker as his tell tale sign of whale. This next tooth has me wondering if it is cetacean or somehow a possible land mammal. I am not sure if it is one tooth with an odd split or tooth teeth fused together with an odd break on one end. It measures 22mm x 8mm: The third oddball measures just 15 mm x 8 mm and I suspect is land mammal. I have nothing to back this up and would appreciate any comments/ideas. Lastly, this specimen looks to me like the roots of a mammoth tooth fused together with some jaw material. I am questioning that id because the ends appear to me to be worn down to this level, not just broken off. I find that a little surprising that the teeth would wear that way. The piece measures 39 mm x 21 mm. Thanks in advance for any comments or input you all can provide.

I have been hunting fossils for 15 years. On Thursday, I found my 2nd ever section of detailed Cetacean jaw material. These are exceedingly rare. It is 2.8 inches in length and has 3 alveoli. It would seem to be more Dolphin size than whale sized. The patina would indicate that the top and 2 sides are relatively complete, and it is broken at the underside. Position wise, this section might be lower right, posterior half of Jaw. Please let me know if you agree this is Dolphin, and what are the possibilities. Here is a photo of Kentriodontae Dolphin with a jaw segment of similar size and lots of teeth !! Please try to give me some insights. Like were the teeth as short as it seems they would have to be to fit this jaw.

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!

Got out to the Peace River, FL yesterday for another hunt. The water level finally seemed low enough that I would be able to get to my target spot and have a productive day. The only problem was the fact that the sun never came out and I had to quit early due to getting wet and cold with no way to warm up. Luckily I had my emergency dry shirt to change into before I started shivering! I always keep one on board the kayak sealed in a plastic bag. Came up with several of the usual items, horse tooth, partial megs, couple of hemis, turtle and a nice gator tooth. Then I pulled up what I believe are an armadillo scute, camelid incisor and a tiny dolphin tooth. The last three I am posting below for some help and/or confirmation on the ID. First a picture of the best of the day finds - Here is what I believe is the camelid incisor. From prior posts by @digit and @Shellseeker along with comparable pictures from @Harry Pristis I believe this is a large headed llama tooth, Hemiauchenia macrocephala. Both digit and Shellseeker found prior examples that they posted here on the forum along with Harry's pictures - One of @Harry Pristis examples: Next up is a small tooth I believe is dolphin. It is only 20mm long so is dolphin possible? Finally, what I have id'd as an armadillo dermal scute - Any help with confirmation or other possible id's would be appreciated, Thanks!

Hi guys, I found this bone on the Bulgarian shore of the Black sea, near Balchik. In the region there have been found the remains of cetotherium sp., dolphins, seals, flamingos and others. I am wondering though what exact bone it is and of course of what. I thought that it may be a part of a fin or something like that, but I failed to find a photo of a bone like this. Any help for the identification will be very much appreciated! And happy soon to be new year!!

Hi All, I could use some help identifying what looks to be a tooth? I found it on Wrightsville Beach, NC. Is it a tooth? If so, what kind? Porpoise? Whale? I have been searching with no luck so I thought I would ask the kind people on this forum. Thanks, J

I have here a tooth from Lee Creek, Aurora, North Carolina. I believe it to be Kentriodon. It's a hair above 1". Does this seem accurate? If so, could it potentially be narrowed down further yet? Thank you, Bellamy
-
I have a dozen teeth from Aurora, North Carolina that I believe to be from the toothed whale Squalodon. Instead of uploading photos of that many, I'm uploading a few that are representative of the dozen and detailed photographs of three of these. For context, the first tooth here is 2.5" long and 1" wide at its thickest.
-
I have here a 3" piece of bone, found in Calvert Cliffs, Maryland. I'm not well-versed enough with these to narrow it down further from marine mammal, and am hoping that these photographs contain some identifying features that may be useful to one more familiar with these. Can it be narrowed down any further?

Fossil ID help: Brachiopod, Crinoid Stems, Dolphin tooth, Orthocone Nautiloid
Praefectus posted a topic in Fossil ID
Hello. I'm working on organizing my collection and was wondering if anyone could help me with some identifications. Thanks for any help. I don't have any info on this one. I think it is a Mucrospirifer brachiopod. Can someone confirm this? Help with the species name would be appreciated. Thanks. These are crinoid stems. I don't have any further information. Does anyone know the species, where they came from, or the approximate age? Thanks. I think this is a dolphin tooth. It was found on the Ernst Ranch in Bakersfield, California. Can anyone help me identify it further? Thanks. Last, here are some fossils I collected when I was young. They were found near Thermopolis, Wyoming. They were found on one of the paleontology digs that the local museum hosts. I think they are orthoconic nautiloids, but I am not sure. 6 year old me was not taking good notes. Thanks for any ID help.

Hey all, I wrote up some more on our recent paper on the giant dolphin Ankylorhiza (formerly Genus Y) from the Oligocene of South Carolina - this is a bit more interesting as it covers the anatomy, adaptations, feeding ecology, and evolutionary implications of the discovery. Hope you can give it a read! https://coastalpaleo.blogspot.com/2020/08/ankylorhiza-tiedemani-giant-dolphin_9.html

I celebrated my birthday recently with three days of shark tooth hunting along Maryland's Calvert Cliffs (Miocene exposures) and had a blast, despite the hot and muggy weather. I still haven’t found that elusive Meg, but I added some great new finds to my growing (since January) collection! Day 1: Matoaka For the first day, I went to Matoaka. Low tide was in the early morning and I wanted to beat both the heat (as much as possible) and crowds, so I got up bright and early, arriving just after sunrise. I’m pretty sure I was the first one on the beach as I didn’t see any footprints in the sand and didn’t see anyone else until I doubled back later in the day. I didn’t find any particularly large teeth but I did find several firsts: my first “cookie” (cetacean epiphysis); first barracuda tooth; first thresher shark (Alopias sp.) tooth, I think; and first Miocene croc tooth (a bit worse for wear). I also found a root worn Carchardon hastalis (above on the far right) and a few dozen other teeth (Hemipristis serra, Physogaleus contortus, Galeocerdo aduncus, Carcharhinus sp., and Negaprion eurybathrodono) in various conditions, shown below.

Want to read more about the giant dolphin Ankylorhiza (="Genus Y")?
Boesse posted a topic in General Fossil Discussion
Hey all, Since COVID began and I've had more free time I've been getting back to blogging, and now I'm regretting taking such a hiatus since I started here in Charleston. I've written the first of a 2 or 3 part series of semi-technical blog articles that most here should understand and appreciate on our new study on the giant dolphin Ankylorhiza tiedemani (formerly known as Genus Y). The first post is about the background to our paper, and the second one will be a bit more on the anatomy, feeding behavior, locomotion, and evolutionary implications of Ankylorhiza. Take a read here: https://coastalpaleo.blogspot.com/2020/08/ankylorhiza-tiedemani-giant-dolphin.html

Found August 1st in Calvert Cliffs State Park in Maryland. Found digging around in deposits about 4 feet into the water. Area is known for Miocene fossils... Sharks teeth, vertebrae, whale bone, etc. It is definitely stone not some kind of metal.

Whale, dolphin, or porpoise? A meaningful question about meaningless terms
Boesse posted a topic in General Fossil Discussion
Hey all - in discussing my recent research on the new extinct dolphin Ankylorhiza with science journalists, I was reminded of previous frustrations from earlier discussions with students, museum visitors, fossil collectors, journalists, and even other scientists about the meaning of the words whale, dolphin, and porpoise. Some disagreements were on this forum, others were on facebook fossil groups - the whole notion of "that's not a dolphin tooth that's a whale tooth" or vice versa is plagued by the fact that these terms have multiple established meanings and are imprecise, leading to lots of confusion, to the point where I pretty much have to start every discussion off with "there are two groups of cetaceans living today..." - many, for example, are confused about toothed baleen whales existing if only odontocetes have teeth. One thing I tried was to conduct a twitter poll showing four modern species and asking if people thought they were a whale, dolphin, or porpoise - and the majority was right only half the time: a leaping beaked whale was thought to be a dolphin, and a small dolphin was thought to be a porpoise. I've had so many discussions on here and have had to repeat some of these arguments ad nauseam, so I thought I might as well crystallize my thoughts into a blog post. I hope you enjoy it! http://coastalpaleo.blogspot.com/2020/07/whale-dolphin-or-porpoise-meaningful.html

While working in James City NC today I ran across someone else's find sitting on a bulkhead. It appears to be modern but it was still something to see completely intact.

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 need help identifying this Bone I found after a storm at OBX. The sandal in the picture is a mans size 10.

I have recently found dugong, whale, and dolphin ribs. Hunting friend gave me a tiny rib that we both thought might be dolphin. He is NOT a bone collector. I found a small dolphin tooth. It is 13mm. How small do these get? and then a predator tooth. I will just leave the photos, and request comments and identifications.

Hi all - I did not have time in January when I normally write these up, but thanks to Covid quarantine I managed to get some time last month and write up a comprehensive review on my blog of every single 2019 paper in marine mammal paleontology. Enjoy! https://coastalpaleo.blogspot.com/2020/05/2019-in-review-advances-in-marine.html
