Stunning view of a monarch caterpillar outside the museum today.

En for numerical ranges and stuff (usually page numbers in a citation, or a span of time millions of years ago). Em for setting off a chunk of text.

📣 Abstract submission is now opened for the 12th European #Paleobotany and #Palynology Congress : www.uni-muenster.de/GeoPalaeonto... 🌿⛏️ Deadline is May 31. Don't hesitate to contact me if you have any questions about our symposium for early career researchers.

Applications for the ASIH Raney Fund are due in 10 days! Please spread the word if you know a student that could use funding for fishy research. I'm chairing the committee for the awards this year and am happy to answer any questions about it

I Want My DinoTV: Walking With Dinosaurs E1 Walking With Dinosaurs is back - and even better than before.

This week in I Want My DinoTV, the new Walking With Dinosaurs!

I really liked it, and it fulfilled a wish I had when I saw the original a quarter century 🙀 ago.

Nice to see the classic Colbert book in there - we had a copy in my small-town Carnegie Library, which I checked out multiple times. The pictures of scientists in action were riveting! When they deaccessioned the book, my mom snagged it, so I have this exact childhood copy in my office now.

A good friend was hosted on a museum visit by Dr. Osmolska....they said she was the kindest, most gracious, smartest host! I am sorry I never got to meet her.

That is the *best*! We are fortunate to live where it's easy access to safe solo biking, basketball, etc., so that's a major part of the evening routine for our kids. "Go bike around the track 6 times!" #BoardingSchoolLife

Folks planning on attending the SVP meeting this fall: Would you be at all interested in a professional project management workshop? I'm considering submitting this for the meeting. I think it could be really valuable on multiple axes.

Yes (although given external obligations I rarely am able to attend workshops!)

In any case, those are some semi-random thoughts, about a topic that sticks in my craw!

So, I think it's fair to say that *most* dinosaur paleo types are pretty savvy nowadays to the impact of ontogeny, it's still an evolving target, and thanks to the work of many, it's becoming increasingly clear that juveniles *can*, with care, sometimes be diagnosed to genus/species.

Sticking things into phylogenies is *not* the sole reason for taxonomy. Yes, we need to recognize how juvenile individuals might fall out "incorrectly" on a tree. But...there are some methods to account for this. And once again, tree-making is not the only reason to name something.

Another objection (or implied objection) is that we shouldn't name things based on juveniles because juveniles tend to show "ancestral" traits that pull them into an incorrectly "ancestral" position on phylogenies. To that, I say - so what?

So, it is *totally* fine to erect taxa based on juvenile or likely juvenile specimens, with appropriate caution and (ideally) an understanding of ontogeny in related taxa.

But - something that should NOT be missed in this (or other papers!) is that although *some* traits do vary ontogenetically, others do *not*. The key is in recognizing the difference. During the past 10-20 years, this has been a BIG part of many (but of course not all) papers.

First - "ontogenetic nihilism" is a term I use for the attitude that because some traits change with growth, we can't *possibly* erect species based on juvenile/perceived juvenile specimens. (I am making a *bit* of a straw man here, but some comments on this & other work reaches very close to this)

TAXONOMIC REASSESSMENT OF JUVENILE TYRANNOSAURINE SPECIMENS FROM ASIA REVEAL LARGE BIOGEOGRAPHIC RANGES IN TYRANNOSAURIDS The recently named tyrannosaurid, Asiatyrannus xui, from the Nanxiong Formation of southeastern China bears a striking resemblance to juvenile specime…

Great new paper on tyrannosaurid taxonomy, showing that Asiatyrannus is likely a juvenile Tarbosaurus (among other interesting findings). Open access!
As often happens when these kinds of papers are published, I see flickers of ontogenetic nihilism in some comments. My thoughts/cautions. (thread)

We’re looking for researchers in any discipline of natural history: if you have a paper coming out and you want to pitch @pbseons.bsky.social on a potential episode about it, send me a DM! #scicomm #paleosky #FossilFriday

(Arsinoitherium says please and thank you!)

Proportions of problems related in submissions.

Important article on the practices of article writing, submission and troublesome reproducibility of the fossil vertebrate phylogenies.
In my view, most see phylogenies as eternally provisionary and probabilistic pictures.

As a past editor for Society of Vertebrate Paleontology annual meeting abstract volumes, the en-dash and em-dash are my lifelong friends.

I was into ceratopsians before they went mainstream. Everyone else is just a poser.

In light of trying to lighten moving costs (finally bought a house) I am once again offering originals for sale. Prices vary with the painting. Pretty much everything I have is available. Please dm if interested. 🎨 #paleoart

Our new paper on a tiny Wealden 🐊 is now out, with @tetzoo.bsky.social, @neilgostling.bsky.social and co. As a critical taxon close to the origins of the living croc lineage, we used microCT to build a comprehensive morpholgical atlas to reassess its evolutionary relationships. tinyurl.com/4t592crr

We all have different style preferences, but please remember that the art was made by a human being. And my hot take...the art resonates with me for its intended purpose. It ain't the artist's fault the animal looked stupid.
