For #FossilFriday a panoply of the basal #ankylosaurid Liaoningosaurus, known by literally dozens of juvenile specimens. The largest specimens are around 50 cm #thyreophora #ornithischia

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.

Haolong dongi, amazing new spiny (yes,really) iguanodontian from early cretaceous china #sciart

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.

Skull roof elements of Tuojiangosaurus. The supraorbital (n.6)show and interesting pattern of conspicuous tubercles. While stegosaurs have often ornamentations in the shape of grooves and pits the supraorbital of T. vaguely recall the caputegulae of ankylosaurs #thyreophora

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. 🔭🧪

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.

more progress....almost done with the head details

Thinking about ankylosaur cervical spines (neck armor) today in the @denvermuseumns.bsky.social collections. How many morphs are there? What bones are homologous? Can I just have ONE articulated animal?!?

I know....., we have growth series of 2 species of large iguanodontion that get pretty big and two fused up sacra in this size range. A 3rd small taxon in the bone bed escalates the taxonomic complexities. Need to pull together the associated skeletons.

I'm absolutely exhausted due to all the fossils this #FossilFriday. @stupond.bsky.social and I spent Tues & Wed unpacking and cataloguing an ankylosaur.. 357 bones... while @valdosaurus.bsky.social , Ricardo and I spent Thur& Fri working on an iggy from Sussex.. another new species, maybe.

The Triassic of India is pretty under sampled so always good to see a new taxon!

So, we have a late Cretaceous Lagerstätte...in Africa!? Finger crossed for further development www.palaeosa.org/uploads/4/5/...

If you see this, post a vampire.
