Underemployed necromancer. 🧪⚒️🦪🌊☠️ Geoscience educator, paleo/sed prof somehow talked into trying on the min/pet hat. Living in the past and talking to dead things since the late Holocene. ❤️☮️⚖️ Opinions mine & do not reflect those of my employers.

When we don't adequately fund public universities, and instead force students to take out loans, what we as a society are really doing is borrowing money from the younger generation—their hard-earned future income—to fund a necessary project that benefits us all: building an educated society.

1. This is bullsh*t & an epically stupid policy completely detached from any empirical evidence: bsky.app/profile/mcop... 2. We could simply avoid this entire issue by <all together now> Funding. The. Damn. Public. Universities. Like. We. Used. To: bsky.app/profile/mcop...

Some large productid brachiopods for #FossilFriday ⚒️🧪 While most brachiopods tend towards the small side for benthic invertebrates, often just a few mm to cm, late Paleozoic productids could get relatively large. There's a good case for the bizarre reef-forming taxa being photosymbiotic.

Just a quick cuttlefish for #MolluskMonday 🧪🦑 Fun fact, cephalopods generally can't perceive color but cuttlefish eyes are adapted to detect light polarization. It is unclear whether this is more help or hindrance in their investigation of optical mineralogy.

THISTHREAD 🧪⚒️ I've taught geology so many places, and while there's more to it, this captures the disjunction between 'elite' research oriented faculty and the realities of keeping Geology sustainable, from the perspective of people who understand the importance of teaching it to everyone.

Brandon Bishop@brandontbishop.bsky.social · 2w ago

Wait. There are seriously geo faculty that do not understand that the general "intro to geology" course is vitally important to their department's recruiting/funding, the field propagating itself, and *the educated public knowing anything about geology and earth sciences*?

All right, gang ... looks like I'm (adjunct) teaching Mineralogy for the first time this fall! I'm rusty (or is that goethite?) I've dug up my Crys/Min notes and have tabs full of NAGT resources open on my laptop, but hit me with your favorite resources, approaches and best practices! 🪨⚒️🔬

NWS confirms that an EF1 🌪 tornado touched down directly across the route I had planned to travel to help with a library event on paleontology. At about the time I would have been in the touchdown zone, if I hadn't listened to warnings and called in to postpone. Listen to the warnings, kids.

If you are interested in a non-technical summary of our recent paper on how Cretaceous monsoons, tropical cyclones and tides created the exceptional Villaggio del Pescatore dinosaur fossil site, check out this piece I wrote for @theconversation.com: 🦖🌪️ theconversation.com/storms-that-...

Storms that built a graveyard: ancient monsoons created a spectacular dinosaur fossil site

A new study has found that layers in the rock record days, not years, representing storms.

Hey Siri, show me a system that looks to filter out the scientific discoveries of women with seniority. The paper confirms the hostility many of us feel is baked into the editorial & peer review community (sitting behind a veil of anonymity) that prefer to see papers led by women thrown out.

Excerpt from the paper:

Gendered effects in peer review
At Science and Science Advances, manuscripts with women corresponding authors make up a gradually declining share from submission to review to acceptance (20.9% → 20.8% → 19.7% → 17.9% and 22.3% → 21.4% → 21.3% → 20.1%, respective-ly; Fig. 2B). Accounting for available covari-ates via multiple logistic regression reveals a small but statistically significant association with corresponding author gender in being sent to review or accepted after review (B =
-0.08, P < 0.001 for sent to review; B = -0.13, P
= 0.011 for accepted; tables S8 and S11).% plot of women’s representation among first authors (solid symbols), corresponding authors (open symbols), and among first-round peer reviewers (crossed symbols) over the evaluation process. Red line and symbols indicate the journal Science, blue indicating Sci Adv. all lines generally trending down from Submission stage, through editorial and peer review stages to acceptance stages.

Some graptolites for #FossilFriday ⚒️🧪 While the convention has been to call these a long-extinct group of colonial pelagic hemichordates that died out at the end of the Paleozoic, the living pterobranch Rhabdopleura seems close enough to be considered the last of their kind. Like tuataras.

A black, fine grained mudstone covered with light, bifurcated fossils resembling tuning forks, if the tuning forks had hacksaw teeth.

When we said "the world is on fire," maybe we should've remembered the stupid script writers take everything literally these days. There is no subtle foreshadowing in this timeline, only invocation.

This piece heavily quotes my colleague David Jeffery, the last geology prof at Marietta College (a small liberal arts school with an international reputation for their petroleum engineering program). If he's worried, I'm worried. Ohio has built quite an industry in wastewater injection.
