All right, let's do this one last time.
My name is David Clark. I was bitten by a radioactive crinoid, and for 13 years I was on the bird site as clarkeocrinus.
I'm pretty sure you know the rest.

So either Trump spoke to Bolsonaro about plotting to escape to the US right before the latter got caught trying to saw off his ankle monitor, or Trump imagined a conversation he didn’t have. Both scenarios are incredibly dark
An amazing new Trump controversy, Part II of II:
- Saturday afternoon: Trump says he spoke to Bolsonaro the night before and planned to see him “in the very near future”
- Monday afternoon: The Trump White House isn’t sure whether Trump actually had the conversation he referenced two days earlier

Did the Republican president talk to Bolsonaro as the Brazilian plotted to escape? Trump said yes, but the White House isn’t so sure.

Must be nice to have a real supreme court
Bolsonaro gets 27 years for his attempted coup to hold power in Brazil. Trump is acquitted by Republicans in impeachment & then re-elected so he can inflict more ego-driven destruction at home & around the world. www.theguardian.com/world/2025/n...

Every bit of this only reinforces Joyce Carol Oates’ absolute roast of Elon Musk as fundamentally lacking in the ability to enjoy anything normally human. “I built a tool that can insult people in a social setting better than anything ever invented” is a real personal tell.

Working on invertebrate #paleoart at the moment, knowing I'm probably making mistakes despite best efforts, consulting primary literature etc. Inverts are much like fossil plants: there are few accessible resources on their appearance so we must wing it, or go down deep rabbit holes to restore them.

if there's a reason to keep up the "tribunals for all involved" discourse one such reason it is to put in stark relief how far away some of the Dem politicking is from the mood on the ground
eric swalwell said on msnow that a major goal of a dem majority after the midterms would be for ice masks to come off and badges to come out, this is insufficient

I actually thought I had shared this on here and I hadn't. But if you want to look at why Tehran has to move it's climate change, yes, but it's genuinely fascinating as a failure of long term planning/ not understanding water supplies.
you'd think the forced displacement of 10 million people from one of the oldest centres of civilisation in human history would get a little more news attention than beltway journalists writing essays on how Olivia Nuzzi is a genius because they want to bone her and you'd be wrong

Democrats should make crystal clear that whether it is high level Trump officials, commanders carrying out illegal murders, or ICE/CPB goons, investigations and indictments are coming—referring to state AGs if Trump blanket pardons for federal crimes.
Dipshit is smashing out a car window with his gun, barrel first. Just rogue, cowboy stiff.
There were two US citizens in the car. They were apprehended and detained for “obstructing” ICE by honking their horn to let people know ICE was in the neighborhood.

Here is the crinoid Arthroacantha carpenteri with a Platycerid snail attached. These snails are Coprophagous which means they ate fecal matter. The snail would attached to the anal chimney of the crinoid and would feed on the waste.

Platycrinites bozmanensis crinoid from the remote Mississippian Lodgepole Fm. of Montana. This specimen also has a Platycerid snail attached to the calyx (bottom left).
These snails were coprophages and would eat expelled waste from the crinoid.
