Back from exile: archaeocete whale discovery in South Carolina
Boesse posted a topic in General Fossil Discussion
Hey all! Between an ill-timed conference, election month, the pandemic, online teaching, and a few other issues, I was way too stressed out and busy to be on here regularly since October. Also, in mid November we began digging up a small basilosaurid whale in Harleyville, SC - very likely to be the most completely known specimen of the dwarf basilosaurid Chrysocetus, and perhaps the most important basilosaurid discovery in North America of my lifetime. I did manage to write a blog post about our fieldwork, so as an apology for being AWOL and only getting back to identifying cetacea- 18 replies

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

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: -
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- 18 replies

Hey y'all - we finally re-named "Squalodon" tiedemani, now known as Ankylorhiza tiedemani - a large macropredatory killer whale like dolphin with some implications for the early feeding ecology of odontocetes (toothed/echolocating whales) and convergent evolution of swimming in baleen whales (mysticetes) and odontocetes after their split some ~35-36 million years ago. I've copied our FB post text below so I don't need to re-type it all. Introducing the species formerly known as Genus Y: Ankylorhiza tiedemani! This large dolphin was originally named from a partial but uninformative

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

What's the best way to upload photos here, given the 390 Mb limit?

Hi, I am currently writing the manuscript of a field guide to fossil cetaceans, but does anyone have a PDF of the following paper that you can send to me: Whitmore and Kaltenbach, 2008. Neogene Cetacea of the Lee Creek Mine, North Carolina. pp. 181-269. In: Ray, Bohaska, Koretsky, Ward, and Barnes (eds.), Geology and Palaeontology of the Lee Creek Mine, North Carolina, IV.

This is our 6th-8th grade fossil program. I was not going to start running these until the fall of this year but thanks to an awesome donation and a few identifications from @Boesse , I am going to do a few with these with displaced students from Paradise really soon. They need creative education and I need a few opportunities to do the lab and make tweaks. I am super excited and extremely nervous about this lab. Marine mammals are so well adapted to an aquatic life that they really present a great opportunity for presenting complex scientific concepts to kids. The difficulty in using fossils

I hardly dare to ask, ... Here is an online offer from someone without even a single feedback, claiming to offer one of the rarest things there is: a piece of narwhale tusk. Looks like flint or agate to me. maybe good for a laugh?

Hello together, I am interested in all things cetacean, but also sirenians, desmostylia, pinnipedia or maybe marine reptiles. What I can offer are some carpatian cave bear bones including a complete paw of which I dont know if its composite. mammut jaw fragments, big bovine and cervid skull fragments and similar stuff. i could also offer to custom build skeletal models, although I can´t guarantee for quality or fast delivery (depending on what you may want) I also could offer an yet unpainted (or painted, if you wish) resin model of dunkleosteus terelli, bought from -
Hi all! The Mace Brown Museum of Natural History will have a table in the community center this saturday at the Aurora Fossil Festival. I'm currently trying to write up the marine mammal assemblage from Belgrade Quarry, which appears to be transitional between the upper Oligocene Chandler Bridge Formation here in Charleston and the late early Miocene assemblage from the Pungo River Formation in the Lee Creek Mine. Bring your Belgrade marine mammal specimens to our table, I'd like to see them! Several members of this group and the exceedingly generous North Carolina Fossil Club have already don

A Miocene Breeding Ground of an Extinct Baleen Whale Found in Japan

Introducing Coronodon havensteini - a new toothed baleen whale from South Carolina
Boesse posted a topic in Fossil News
Hey all, On Thursday some colleagues and I published a new archaeocete-like baleen whale from the Oligocene of South Carolina. This is one of the most primitive baleen whales known, and the skull bears many primitive features in common with basilosaurid archaeocetes. We named it Coronodon havensteini - Coronodon refers to the cusps which make a crown-shape, and the species name after Mark Havenstein who collected the specimen. A life restoration I've made of the animals likely gross-looking mouth can be seen below, along with a photograph of the skull. Here's some press- 20 replies

The "Cone Whale" is now on display at CCNHM, Charleston, SC!
Boesse posted a topic in A Trip to the Museum
Hey all, Our collections manager and I have had a pretty busy week, and finished the first phase of the installation of the "Cone Whale" - a baleen whale skeleton collected from the Lee Creek Mine by Lee Cone (President of the Special Friends of the Aurora Museum). The specimen is the most complete whale skeleton ever collected from the mine, and was hauled out a few bones at a time over a two week period in Spring 2007. It includes a partial disarticulated cranium with an earbone (petrosal/periotic), left and right mandibles, all cervical vertebrae, most of the thoracics, and poss- 3 replies

This a whale cervical vertebra that was given to me 10-12 years ago. It is from the Middle Miocene Sharktooth Hill Bonebed (probably Bob Ernst's old "Whale Quarry" judging by the preservation). You will notice an unusual trough-like depression (perhaps 3-4mm at its deepest) in the bone surface. For years, I thought it was a bite mark though it seemed like a weird one. Then, a couple of years ago, I found this publication: Thomas, H.W., Barnes, L.G., Klein, J.E, and S.A. McLeod. 2008. Examples of paleopathologies in some fossil Cetacea from the North Pacific realm. In Wang, X. and L.G.
