The Oviraptor With No Name by Jaime Headden | Redbubble
Skeleton of the best known, most complete large oviraptorid, referred variously to Oviraptor or Citipati, it likely deserves its own name and full description.

As we crawl our way into the holidays, think about stopping by my Redbubble shop and pick up a shirt or mug or phone cover or something.
New designs are being added, including this GIN 100/42, the best oviraptorid in the world.

The first non-Pterodaustro pterodaustrin pterosaur (Pegas and peers remove Gegepterus and other ctenochasmatoids from the group on account of lack of synapomorphies) from anywhere.
Found inside a regugitalite! That's an upchuck stone for the rest of you. Or a vomitite, I think it was also called.

🧪⚒️Welcome the first filter-feeding pterosaur from Brazil: Bakiribu waridza, from the Araripe Basin!! 🥳
The new species is AWESOME and was discoverd inside a regurgitalite 😱🤍

An ornithischian, perhaps a thescelosaurid or maybe an elasmarian, with what I'm unlovingly and unflatteringly calling "Skeksi face," with all due apologies to Brian Froud and the Henson Company.

This bears reiteration.
Regardless of your implied fandom, the science that goes behind 1) naming and 2) deconstructing said name is not fraught with jibes and ripostes on the debate floor. It happens in papers, where evidence is presented (or not, in some cases) and assertions live by merit alone.

Let me attempt to articulate something. As a former participant in the "teenage nerds talk about dinosaurs online" scene, I think some of us who follow paleontology as adults or do dinosaur stuff professionally care too much about the specifics of what's being discussed there. (cont'd)

How many times do we have to go over this? If you see a unicorn, just let it go. Don’t get closer, don’t try to pet it. No good will come of it. Just check the unicorn off your life list and walk away.

Pure evil can only be fought with pure intent. Fascism, and all other forms of authoritarianism, tend towards the corruption of whatever intangible central portion a person might name for themselves, without temper or give.
Evil begets evil, and good can never serve it.

This should be discussed more extensively.
I once had a researcher complain about my reconstruction of a pterosaur on account of the previous argument that, because the uropatagium in Sordes is weird (tail turned to the side) that uropatagia attach to hips, not tails, and the tail is loose.
