I'm Spencer, and I'm a PhD student at Oxford studying paleontogy! More specifically, I'm looking at the evolution of tails in synapsids, which is the broad group that includes both mammals and everything more closely related to us than reptiles! I've also worked with marsupials and multituberculates

I have nothing of substance to add re: the condemnation of paleo associations with Epstein, but as the initiator of one of the more recent high-profile SVP ethics cases who spent months going through their process, I have some thoughts re: SVP's handling of ethics cases/reports.
A thread 🧵:
A thread 🧵:
Really SVP? You’re just going to ignore decades of sexual and academic misconduct, marrying a student AT one of your conferences, and every report I’ve filed (implying that’s what you do with reports) to defend famous Horner? You’d rather have pedophiles than students is your message?

basically yglesias, jain, jentleson, WelcomePAC donors etc all base their prescriptions for Dems on a statistical model that nobody can replicate, and refuse to acknowledge (a) that uncertainty dwarfs the detectable effect of moderation & (b) that the last year has proved their views wrong!!

Hmm, sounds like we need a refresher. The issue of whether everyone's favorite long-neck is called Brontosaurus or Apatosaurus (or both) has *nothing* to do with which skull was historically included on museum mounts! 🧵#FossilFriday

I'm not joking when i say race science dipshits think people are pokemon, but it's rather less funny that a eugenicist has been an assignment editor for much of the mainstream press for the past six years

ryan fazio go away challenge
Ryan Fazio, Republican state senator from Greenwich running for governor, weighs in: "The secretary is a good person who cares about our state and country. You can disagree with her policy views, but disinviting the Secretary of Education from visiting with students is not defensible."

I've been holding my fire on this, but this is unbelievably fucking weak. Resign and wander off into the suburbs, asshole. Take the rest of the caucus with you while you're at it
SCHUMER says Democrats are “united” behind three DHS reforms
1/ End roving patrols; tighten the rules on warrants and require ICE to coordinate with local authorities.
2/ Enforce accountability; a uniform code of conduct.
3/ Require masks off, body cameras on, agents carry ID.

AOC: "An ICE officer had violently pushed a woman to the ground and he had come over to help get her up and that is what precipitated this incident that very quickly led to an execution in the streets. What we are seeing here is a momentous pivotal moment for the United States."

BTW when I say abolish ICE, I mean abolish it entirely and replace it with exactly nothing. Give me your tired, your poor, your huddled masses yearning to breathe free. That's it.

AOC: An agency that is attacking U.S. citizens, kidnapping five-year-olds and using them as bait, and privately circulating the idea that they can violate the rights of Americans by busting down their doors—they deserve to be defunded, and I’ll take any step in that direction.

My train from London to Oxford was cancelled halfway through once we reached Reading, so we have now been provided with a rail replacement…taxi? I mean I’ll take it over a bus but it’s the first time I’ve ever experienced anything like it

rare to see an american politician speak in these terms and it rocks
“When I speak about making our city more affordable, my vision is not limited to the homes that we live in or the child care that we’re making universal — it’s also a vision where we make it possible for working people to afford lives of joy, of art, of rest, of expression.”

Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...
