Saint Lucy’s Day, 13 December, means baking ‘lussekatter’ - ‘Lucy’s Cats’ - which are soft, sweet saffron buns made into shapes the significance of which is lost in antiquity. Just out of the oven! I wish 🦋 had smell-o-vision.

Yesterday I picked up a fun Swedish language (Svenska) book that has been surprisingly useful and enjoyable to read. This evening my new phone case came in the mail. The rest of this evening will involve writing, segmenting, drawing and an old fashioned.

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity
Hadrosaurid dinosaurs are generally regarded as “crested” or “non-crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non-crested” hadrosaur is known to ha...

Happy Thanksgiving! I'm thankful for Centuriavis lioae, a 10 million year old fossil relative of turkeys. It was a lot of fun describing this stunning specimen with Catherine Early, Kate Dzikiewicz, and Amy Balanoff. The fossil is named after our amazing museum colleague Suzanne Lio.

Check out this new paper in Systematic Biology! Aside from the author list including leaders in the field who happen to be some of my favorite scientists, this paper discusses * both * phylogeny inference incorporating continuous characters AND dicynodont evolution. How cool is that? 🧪
Incorporating continuous characters in joint estimation of dicynodont phylogeny
Abstract. Continuous characters have received comparatively little attention in Bayesian phylogenetic estimation. This is predominantly because they cannot

Hey, readers, thanks so much! Picador US's trade paperback reprint of City of Saints & Madmen is now in an eighth printing? This was my break-out book back in 2002 and it's amazing to see it still reaching new readers over two decades later!
