New paper alert! (My first!)
This is a benchmark paper on all NPS fossils within the State of Utah through 2024. Loads of illustrations by me and pic by coauthors and collaborators. Open access, free to download! Thanks to all who made this possible!

A little #FossilFriday mystery from the Hell Creek for you other experts. I found this in a bunch of pieces trailing down the outcrop. What is it? Smooth on the underside, horns. Sutures?
Definitely not Pachycephalosaurus, can't place it on a ceratopsian either. 🦕🧪

I'm putting the new weird horned dinosaur that I found in Montana away, but wanted to compare it with the same bones from Princess Lumpybumps.
I am surprised at how different they are, especially the fused frill lumps (episquamodals) in overall size and proportions. Can't wait to dig more ! 🧪

Whooooaaaa, this is extremely neat!
And spectropolarimetry (which is the best, and what we used in my first paper too!) is at its core 💙
In a nutshell: astronomers used the polarization of light to study the shape of a supernova explosion before it interacted with surrounding material.

For the first time ever, astronomers have unveiled the shape of a supernova explosion just a day after detection, as the blast was breaking through the star’s surface.
Achieved by our VLT, this feat will help us understand how massive stars die: https://www.eso.org/public/news/eso2520/

My 3D anatomical study of a large male Pteranodon longiceps. The skeleton is a generalised composite as per usual with my models, but is scaled to UNSM 50130 (a very large and almost complete wing)

I made another discovery today: a new (old) instance of the Demonic Elongated Quetzalcoatlus! And It's attacking London! Apparently it is from Look and Learn, a British educational magazine for children published in 1982.
