Couldn’t agree more with the idea that we MUST center students in education. Everything we do should be for the students and their learning, not profit for tech companies testing garbage machines.
"We envision a resistance that is...a repudiation of the efficiencies that automated algorithmic education falsely promises: a resistance comprising the collective force of small acts of friction."

Seems to be a Silurian coral! Probably the oldest fossil I’ve found on my parents property. Thank you for the information from several people.
Invertebrate paleo people: can anyone ID this? Found in glacial till in Michigan and I am not sure what this is.

Bring back giant predator salamander things with flat heads!
Frankly the world should look more like Douglas Henderson’s Triassic scenes

Everything alive in the Devonian period tried too hard. “Ooo, look at me, I’m a weird elongated pentagon” Shut up!

Seeing some people mocking these concerns but we should listen to student concerns. I needed a wrist brace for a month after final exam season my sophomore year of college from writing notes. Would prefer not to do that to my students.
Does anyone else bristle at this framing? WSJ says blue books are “torturing” students with hand cramps, and “nobody likes them.”

Listen, students have been outsourcing everything to AI and cheating their way through college. Blue books should be celebrated as a return to authentic human learning.
They Were Every Student’s Worst Nightmare. Now Blue Books Are Back.
Cheating with ChatGPT has become a huge problem for colleges. The solution is painfully old-school.

My great grandfather’s scythe, very cool artifact at the family farm.

Found in my fossil collection. Bit of a challenge but anyone want to guess what this is?

Whoa very cool. Can’t wait to read!
Out now: latest addition to the Grande volume! Guang-Hui Xu reevaluates Guizhoubrachysomus from the Middle Triassic of southern China. Interpreted as a "luganoiid" in the past, this work argues Guizhoubrachysomus is instead an early dapediid, a group most famous from Jurassic deposits of Europe.

I have so much empathy and solidarity for those struggling with the painful and structurally unjust academic labor market, but this racial grievance shit is simply not the way.

Apparently no departments of pseudobiology were hiring!
Another incredible case of white racial grievance about the academic job market.

He reveals at the end that he wouldn’t provide the necessary application materials!

Despite the difficulties of this year, can't say enough how grateful I have been for my students at VT and now Bowie State this year. Worked with a lot of brilliant, hard working people who make teaching a joy.

Citing myself to a reviewer

Draft from a paper I’m working on… the triangle at least a hundred species in it btw :)

How it feels to cite yourself.

Cannot agree more with this. Overall, I have had a fantastic experience with collections/collaborations. There are a few unnamed places that actively hold the science back and need to change how they do things.
I hate navigating the world of palaeontology. "If you author with this researcher, you'll be barred from working with that other research team" or "if you access this collection you can't access that collection". Petty cliques getting in the way of accessing public resources and good science.
