Oh baby....Yooouuuu!

You got what I need.

But you say he's just a friend.

This is what I draw/paint invertebrates.

We need more art, even if it's speculative. Create things!

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

Twitter Conservatives finding out all the hot MAGA mom accounts they've been gooning to are actually run by men in developing nations

Original oil painting by Tisha Mark, "Late Autumn Wish" 6"x6" oil on Ampersand Gessobord (2025). Loosely painted abstract-leaning atmospheric seascape with earth tones on a dark shore. The sky has orange and gray tones with hints of blue.

I'll be sharing some small works for today's #BlueSkyArtShow theme, #small

These are nice for gifting if you happen to be looking for gift ideas 😊🎨

I have lived through the entire rise and fall of search engines

Please reach out if you are serious about building a prep room. I can help with suppliers and advice.

I have a nice prep room that I've built up over the past 20 years. I use abrasive powder and an air scribe to remove the surrounding matrix.

It's expensive to get a dust collector, air compressor, blast cabinet, and other tools, but it's the best way to prepare fossils.

Here's a couple different views of the specimen.

Does this help?

Ah. Nope. That's the crinoid stem. Platycrinites have oval shaped columnals (discs that make up the stem) so it has a cork screw type shape.

Here's another Platycrinites with the stem stretched out.

Just a reminder, “Epstein” is the name of the sex trafficker.

The president is called “Epstein’s monster.”

I don't know, I just think art should be an earnest, heartfelt expression of emotion and lived experience, you know? A machine that cannot cringe cannot make art.

Nope. That's the snail attached to the crinoid.

Ankylosaur tail clubs from the Royal Tyrrell Museum for #FossilFriday of #Anodontosaurus and #Euoplocephalus, one of which shows signs of traumatic injury or disease!

I guess I'm tired of the strongly worded letter phase, because that ain't working with these guys

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.

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.

Yeah. It's about 2-3 inches wide.

The Lodgepole Formation is about 350 million years old.

Before there were dinosaurs.

It's Friday, and apparently bluesky is ready for this fun revelation:

Dinosaurs lived on the other side the Galaxy.

Welcome back to #fossilfriday

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.

🔎A find from my hunt for #fossils: Crinoids from Solnhofen Plattenkalk.

⚒ No need for preparation - nature did it perfectly ⛏

⏳ Upper Jurassic

📍 Bavaria, Germany

#geology #geoscience #paleontology #Solnhofen #fossil

Hunsruck slate is known for pyrite replacement. The fossils can be x-rayed to show soft tissue details.

A close up of this specimen shows the delicate arms and long anal tube to expel waste.

#FossilFriday

Another plate with multiple crinoids, this one is Parisangulocrinus sp. from the lower Devonian Hunsruck slate near Bundenbach, Germany. This plate has 16 crinoids.

#FossilFriday

This plate has 11 specimens in total, all Clematocrinus retiarius.

#FossilFriday

A really nice example of Clematocrinus retiarius from the Silurian Wren's Nest of the UK. The little branches on the stem are called cirri.

#FossilFriday

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.
