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.

To also quote John Lewis:
"Freedom is not a state; it is an act… Freedom is the continuous action we all must take, and each generation must do its part to create an even more fair, more just society."

Just in time for #FossilFriday, meet Rhynchaeites mcfaddeni, a little fossil ibis from the Green River Formation. The holotype looks delightfully like a hieroglyph!

Did some work for Dr. Dan Ksepka on some neat fossil birds. Nice to see the creative way the team that just published this paper put these two together.
And it was only about as big as a pigeon! Here is nice size comparison by @jaimeheaddenart.bsky.social
showing Rhynchaeites mcfaddeni and a modern Glossy Ibis.

ceratopsid noses are really, really weird. Preserved as giant empty spaces inside the skull, only the external features (the narial fossa, the bony nostril) get mentioned. But we've known for a long time that there had to be other things in there.
(This shouldn't influence reconstruction much)

Excited to see this article led by @seishirotada.bsky.social out in @anatrecord.bsky.social. Triceratops and their ceratopsian kin are more than horns and frills! Check out their narial regions! doi.org/10.1002/ar.7...

A succinct rephrasing of an important message from a former comics person, so know what the actual quote is.
Power carries responsibility, and the greater the one, the greater the other. Those who abrogate the latter, don't cry when you lose the former.
Read the thread.

(there's an axiom that goes around about power and responsibility. sure, you many not have asked for the power of privilege; but that doesn't get you out of the attendant responsibility.)

The silence from the established (and largely male, white) paleo folks to whom I have given much respect and admiration over the last few decades to the notorious and now blatant misconduct of "one of their own," infamous Jack Horner, reaffirms my step away from academia.
Sorry, but not sorry.

When that handy dandy Geology degree comes in handy...
For those who need to know (which includes certain astronomers): "sand" as a term in geology is not based on composition. It is a term based on the size of the clasts. Here is the Wentworth scale we use to demarcate the names of the different size classes.

To the authoritarian, if it's not adulatory, glorifying, and to be clear it has to be the *right kind of such*, then it's inherently *hostile*. Any attempt to hold this administration accountable will be deemed "violent." This, from the self-described "domestic terrorists" now on the loose.
Deputy Attorney General Todd Blanche: "He [Alex Pretti] was not protesting peacefully. He was screaming in the face of ICE, he had a phone up right into ICE's face. You tell me: is that protesting peacefully?"

I believe that the original sketch (made a few years ago) was brought on by my anger at the invisibility of intersex people in the public eye, along with how their parents often treat them.
I had no idea what to do for the background tbh

From an outsider's standpoint, this sure does look like an externally grooved, probably spike-bearing bone, doesn't it?
Surprise, it's a human kneecap, os patella, an ossified sesamoid. These bones are often embedded, and formed within, muscles and their associated tendons, alleviating strain.

Hiya, I have 4 more school fact file sheets for #FossilFriday:
#Tianyulong, #Darwinopterus, #Oregramma, and #Caytonia! These are really relaxing to do, and I plan on doing more plants next!
I hope you like them!

I'm making a series of infographics at the moment for some school groups, and, honestly, I'm really enjoying it!!!
They're learning about paleontology, and I was asked if I could provide some images of extinct plants and animals! Here are the first few: #paleoart #scicomm #education #paleontology

The US has been protesting foreign involvement and genocide in foreign countries since its founding. One might, through some marshalling of esoteric knowledge, infer it's been happening since before, too.

There are things today we can't do. Stop worrying about them for now. Not forever; just for now.
There are things today we can do. Focus on that. There are people who need help -- let's focus on them.
Each morrow, we take what we can do, and do it. With what we can't, put them aside.

I should add I left out the next most obvious contrary possibility: that the ossifications are, to some degree, sesamoids. One of the "spikes" occurs in aplace that makes it very hard to use as a "spike," between two digits. It's worth thinking about and testing against, even if not conclusive.
I'm not an expert in egg-snatching, but I've done a fair bit of investigating into the subject, and I'll say right now, most egg-eaters consume their food in situ (that is, in the nest). They don't take it somewhere else. Egg-carrying is highly inefficient, and adaptations for it are questionable.
