A small pale yellow gastropod shell has eroded out of a shell bed, with about a dozen robe-like ridges.

A single clam shell has been subjected to to much weathering, and is fracturing apart, the little bit of matrix inside the shell is just barely holding the slowly separating fragments

A lovely tall-spired gastropod shell sits on a sandy beach.

Oregon trip, part 3: @paleowin.bsky.social, myself, and a couple others visited the middle Pleistocene Port Orford Formation in SW Oregon to look for rare Pleistocene marine mammals. We didn't find any, but visiting without finding many incredible fossil mollusks is impossible!

Three rings: two fossil fish vertebrae, probably "Smilodonichthys" rastrosus, with my wedding ring for scale. These vertebrae are in a small Empire Formation concretion reworked into the Coos Conglomerate. Spotted during an Oregon coast field trip with @paleowin.bsky.social.

Text of press release reads: Miami Beach Bans Land-Based Shark Fishing — The measure is intended to prevent potential injuries to beachgoers — Miami Beach, FL – With millions of visitors who come to soak up the sun and experience the city’s 7-miles of pristine beaches each year, the Miami Beach City Commission has voted unanimously to prohibit land-based shark fishing. The measure applies to shark fishing along the shoreline as well as from any dock, bridge or other land-based structure. “We’re targeting heavy-duty fishing equipment that can cause serious injuries to families or anyone who happens to be enjoying our public beach areas,” explained Miami Beach Commissioner Laura Dominguez, who sponsored the measure. The ordinance notes that shark carcasses have been discovered along the shores of Miami Beach as well as in neighboring communities as an apparent result of fishing or mishandling sharks. “We are not only reducing dangerous human-shark interactions in our swimming areas, but also taking a firm stand against the degradation of our vital marine ecosystem,” said Miami Beach Mayor Steven Meiner. “This is a critical step in ensuring our world-class beaches remain a safe environment for every resident and visitor.” While the primary focus of the ordinance is directed at protecting residents and visitors, the legislation is also intended to prevent the “intentional or negligent capture, injury or killing of sharks within or adjacent to city waters” and to protect endangered marine life and species protected under state law. Shore-based shark fishing requires the use of long lengths of fishing line and large hooks that can pose injury hazards for swimmers, surfers, waders and other shoreline users.

Oh wow, the city of Miami Beach has banned all land-based shark fishing.

I worked on this issue during my Ph.D., resulting in a statewide campaign that tightened regulations for this practice: conbio.onlinelibrary.wiley.com/doi/full/10....

Oregon trip, part 1: a couple of weeks ago @paleowin.bsky.social flew me up to coastal Oregon. Before my lecture, we went out to explore the Empire Formation - a famous late Miocene locality for giant walruses (e.g. Pontolis magnus).

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes!

"Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

Did you poke any? Apparently they molt n’ mate, so if their shells are somewhat soft that’s probably what was going on?

Incredible tidepooling experience: last week in Coos Bay Oregon I saw thousands of northern kelp crabs (Pugettia productus) with @paleowin.bsky.social, all huddled in a large #tidepool. I have no idea what was happening. Bonus fossil scallop if you can find it 🦀🦑🧪

Peppermints are a pretty common horse treat! Although my other horse Sammy hate them… Sausage definitely has more of a sweat tooth. Peppermints are his favorite followed by red vines licorice.

Chambered nautilus phragmocone, dorsal perspective. The outer wall is damaged, revealing hemispherical inner septa separating camerae, each with a small, calcified nozzle indicating the location of the siphuncle.

Chambered nautilus phragmocones in side view. The outer wall of the one on the left is damaged, revealing hemispherical inner septa separating camerae, although the siphuncle cannot be seen from this perspective. The living chamber is damaged but visible, revealing a pearly, nacreous luster. The one on the right is a fragmented partial phragmocone, damaged after an apparent attempt to cut a sagittal section. The logarithmic progression of hemispherical septa is clearly visible.

#MolluskMonday represents today with Nautilus, a modern chambered cephalopod. Like ammonites, nautiloids have an external conch and lived in the final chamber, using the camerae for floatation. However, ammonites were much more closely related to coleoids like Spirula, with its intenal conch. ⚒️🧪

It was near Halloween, but definitely Vegas. There was a dress up event. But positively Vegas with creepy French recordings in the bathrooms and the weird poolside welcome instead of at a museum.

Will always look for an excuse to post this post from Gritty’s official Instagram account.

Thing I just said while grading: “Why is my student’s lab sticky?”

kissing he neck and up her arm and being very handsy… this was over Halloween so I didn’t realize it was him at first as he was wearing a rubber mask until she said “oh Jack, not now” and I realized she was wearing his name badge and him hers…

SVP Vegas. Immediately after the meeting they went to a wedding chapel in the host hotel (the Paris) and there’s lots of photos… supposedly I’ve learned they did a more formal event back in Montana, several months later. I was talking to the student at a round table event and he came up and was-

Fossil Whales of the Pacific Northwest and the Evolution of Baleen YouTube video by Southwestern Oregon Community College (SWOCC)

#worldwhaleday Last week I was invited by @paleowin.bsky.social to give a lecture at her institution (SWOCC) on the evolution of whales. If you want to learn about about the origin of baleen and the importance of fossils from the Pacific Northwest, watch here: 🐬🦖🧪 www.youtube.com/watch?v=s7jg...

Title of infographic: Gift Giving is the Love Language for Ornate Bella Moths “Ornate bella moth females mate with multiple males over the course of their 3-4 week adult lifespan. In each sexual encounter, she will receive a nuptial gift from the male called a spermatophore.” An illustration of an ornate Bella moth, a colorful orange and cream colored moth with black spots, is surrounded by valentine’s presents and a chocolate heart. The tags on her gifts read: TO: BELLA <3 - JACOB FROM: EDWARD XOXO Text continues: “This gift contains sperm, nutrients to help the female lay her eggs, and toxic alkaloid compounds to protect herself and her offspring. She can secrete these toxins from her head when threatened, and infuse her eggs with them.”

“She will consume all of the nutrients and alkaloids from these spermatophores to make sure she and her offspring have the best chance of survival possible. However, she can decide which male's sperm from her gifts she wants to use to fertilize her eggs!” An illustration to the left of the text shows an iPhone opened to iMessage, with an ornate Bella moth on top of the phone screen. Texts from one of her male moth lovers (Jacob) read “Hey Bella. Did you like the gift I dropped off?” And a few hours later: “I gave you my spermatophore pls respond” The text on the infographic continues: “She'll usually choose the sperm of the male who had the strongest sex pheromones - chemical signals used to attract a mate. Stronger pheromones mean more toxic alkaloids, and thus, a healthier sperm donor.”

A Valentine’s Day card that reads “I’d give you my spermatophore any day” with an ornate Bella moth illustration surrounded by Valentine’s presents and gifts of chocolate and balloons. Text that reads “To:” and “From:” is at the bottom of the image. The background is a soft pink gradient.

Happy Valentine’s Day! 💖

Ooo that’s fun! I have a gorgeous classroom and some pretty fun geology toys for a tiny community college!

I got a high up admin to suggest having a small natural history museum on campus, I’m going for full corruption!

I’m definitely going to have to learn more being on the OR coast!

I do not know my inverts nearly shell enough 😅
Me with fossil mammals: 😎🤓
Me with same time period inverts: 🤨🤷

I’m fascinated by trace fossils. We found one great piece of toredo wood today!

I’m spoiled in SW Oregon, this is 10 minutes from my work:

This was my first time at this site. Most of the stuff around me is Eocene or Miocene. (Miocene is my favorite though).
