Just in time for #FossilFriday 🦖 What are the big questions in #paleontology today?

dx.doi.org/10.1017/pab.2025.10042

Nearly 200 scientists worldwide came together to map where our field is headed. Here’s the story 👇

Communing with trematode parasites! Trematode pits on the interior of a bivalve shell, glimpsed this week in @realhuntley.bsky.social’s office

Whelp, wrote too fast before. Perhaps the large specimen is a carditid. There are some rather large paleogene venericardia that are quite similar

Mystery clam! One of my Oregon fossil sites is full of these clams… I know nothing about clams… trying to at least get a family(?) level ID? @dantheclamman.blog

I would also go for cardiidae for the large one and either veneridae or possibly astartidae for the smaller one on the left. I love #NameThatBivalve!

Looking forward to visiting @realhuntley.bsky.social and the U Missouri geo/paleo crew this week!

Here is another Devonian sea star fossil on display in @colgate.edu’s geology museum

Swimming in ancient seas this afternoon with my paleo class here in Central New York and the students found some jaw-droppingly cool fossils, including a sea star! #Devonian #Wundergrads

I love livestreaming the deep sea, especially before class as my undergrad students filter into the room, seeing things they've never seen before. This is possible through the use of ROVs & through federal funding of public-facing science. www.nytimes.com/2025/08/08/w...

It is with a heavy heart that I share the passing of colleague & friend Marilyn Suiter. Marilyn worked steadfastly to support the development of geo colleagues of all career stages, consistently connecting people & highlighting opportunities. She will be greatly missed.

A glimpse into our day at the Diamond Light Source in Chilton, England. Several members of the Paleo Lab are here this week gathering data on the shell microstructures of different marine animals in order to better understand the biotic impacts of anthropogenic climate change.

Congrats to Paleo Lab alum, Charlie Filipovich, who defended her masters thesis today! Fun to learn about her work on Lake Tanganyika benthic communities!

Congratulations to Meredith Shapiro and Allison Wen who presented their summer research in the Paleo Lab this afternoon on campus!

Sounds wonderful! I took a grad class at FHL years ago and have long dreamed about returning at some point. Have fun!

Enraged/heartsore to see gutting of US science. Terminating funded grants is a waste of taxpayer $ & loss of insights prioritized by colleagues during peer review. Firing NSF employees is gutting expertise at an agency already accomplishing so much w/ so very little. www.science.org/content/arti...
Exclusive: NSF faces radical shake-up as officials abolish its 37 divisions
Changes seen as a response to presidential directives on what research to fund

That’s awesome!

The Trump administration this week summarily dismissed more than 400 scientists and other experts who had begun to write the latest National Climate Asst.

As I say here, climate change puts us all at risk, and we all need this vital information. Without it, the future will be much more dangerous.
'It's a huge loss': Trump administration dismisses scientists preparing climate report
More than 400 experts were starting to prepare the latest national climate assessment report. They all received an email from the Trump administration dismissing them.
