Hey all, Part 2 of my blog series on whale and dolphin earbones is here - my guide to identifying isolated dolphin/toothed whale (Odontoceti) periotic bones. Check it out here: https://coastalpaleo.blogspot.com/2023/01/bobbys-guide-to-whale-dolphin-earbones.html Sample image:

Charleston, South Carolina delphinid ear bone
Brett Breakin' Rocks posted a topic in Partners in Paleontology - Member Contributions to Science
I finally made it out in July to a location near Charleston I am always mentioning, but had never personally visited. After 3 dry years of no ear bone periotics they started showing up in triplicate this summer. Probably was able to discern their shape better after seeing so many examples. Not much else showed up for me that day save a few tiny teeth. But it led to my first, albeit small donation. Common or Scientific Name: Odontoceti indet. (delphinid periotic ear bone) Geologic Formation: Undetermined - ( Fossil dredge from this site typically contains Oligocene Ashley Formation, Lower Miocene Marks Head Formation, Lower Pliocene Goose Creek Limestone, and Pleistocene Wando Formation ) Geologic Age: Undetermined - Oligocene (?) But potentially Pliocene - Pleistocene Region the fossil was found: Charleston, South Carolina Museum or University that received the fossil: Mace Brown Museum of Natural History at the College of Charleston Reason for donation: Well preserved and perfect for the fossil survey. Found and donated (July 23, 2019) to Dr. Bobby Boessenecker Dr. Bobby Boessenecker - " Ashby (Gale) and I (but mostly Ashby, since he's out more often) have been putting together a collection of riverbank ear bones from West Ashley, Johns Island, and Mount Pleasant, and this is quite a well preserved one that would go nicely into the eventual paper.

When I started going through the package of donated STH fossils we got this week, this little fossil jumped out at me. It is a cetacean ear bone and it looks similar to a photo I saw of an ear bone identified as Liolithax kernensis, a primitive long-snouted delphinoid. I believe it is a fairly common find in STH. I can not be sure with the limited knowledge I have but it did look very similar. The more information I can get, the more information I can pass on to the kids so any opinions are welcome.

I have a whale bulla and I am hoping to get some ID help with this. It was labeled as a Sperm Whale ear bone but after searching pretty extensively, it looks more like a Mysticeti whale to me. I am far from an expert though so I thought I would post it here and see if anybody has any thoughts on it. It was a dive find in South Carolina. It is a pretty good sized ear bone I think, about 4.8 inches long. Any help would be greatly appreciated.

I recently found a small lot of mammal teeth from Sharktooth Hill. I am doing an education program about marine mammal evolution and they looked like cetacean teeth so I bought them. I am new to fossil forum but not new to collecting marine mammal fossils. I know that you can not get a species ID from cetacean teeth but I am hoping I can get a little additional information or perhaps a suspect so to speak. I believe that the first 3 pictures are of an unidentifed Odontoceti, maybe a Kentriodon of some sort. The first two teeth were both right around 1.5 cm. The third tooth was a little over 1 inch. I am fairly certain the 4th picture is of the unidentified Odontoceti species that is mistakenly called Prosqualodon errabundas by some collectors and dealers. I think it was the Coastal Paleontologist blog that said this was an undescribed species of large dolphin. It is about 1.75 inches long and has a very inflated root. The last picture looks more like an Allodesmus than a cetacean to me but I could be wrong. If anybody has an thought or opinion, I would greatly appreciate any information.

Last Saturday I was lucky enough to pull a nice odontoceti (whale) tooth from a favorite little (literally) spot on the Peace River. This location has very chunky gravel and often reveals nice prizes to repay the effort of digging through golf ball to bowling ball size gravel (if gravel is even an appropriate term for pieces that large). I've found the occasional piece of Long-beaked Dolphin (Kentrodontidae) jaw bone with its distinctive long groove punctuated with dental alveoli (tooth sockets) or the rare small tooth from this species.The item I found on Saturday is significantly larger than these small dolphin teeth measuring 8.5 cm (3.3") from tip to tip and 3 cm (1.2") across its widest girth. Given the size (and searching the few fossil identification books I have) I believe this may be from the family Physeteridae (Sperm Whales). There is a photo near the bottom of page 162 of Frank Kocsis' book Vertebrate Fossils: A Neophyte's Guide that is as close as I've come to something with a similar shape and enamel cap. There is also a nice paper on sperm whale teeth attached to this post from some years back: http://www.thefossilforum.com/index.php?/topic/16591-whale-tooth-id-help/?p=184390 In both of these references my find seems to most closely resemble pictured specimens labeled Scaldicetus sp. but I've learned from Boesse on this very forum that Scaldicetus is a poorly applied term referring to species belonging to over a half-dozen different genera. Given my tooth's visual similarity to the poorly defined "Scaldicetus" does it appear that I am at least correct in assuming this tooth belongs to Physeteridae and that trying to take the taxonomy down any further from this with a single isolated tooth is poorly advised? Looking for some confirmation that I'm on the right course (and have not overshot the runway). Cheers. -Ken
