Maybe a bit late for web timing, but ehy, NEW PAPER ON #fossilfriday!!!
I am proud to present you Haolong dongi gen. nov. sp. nov., a new hadrosauroid from the Early Cretaceous of China!
The specimen, almost complete, is a juvenile iguanodontian from the Yixian Formation of the Barremian (125 Mya).

Really taken with Haolong dongi, out today from Jiandong Huang, Pascal Godefroit and team. Just submitted news article on it. An iguanodontian with abundant hollow spikes across the neck and body, projecting from among conventional basement scales, and with rows of plate-like scales along the tail.

Since it's #haolong day and #fossilfriday here's some #iguanodontian specimens from Liaoning, spanning from 40 cm to over 8 m, many preserved with soft tissue.

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/
