Happy to present the latest work from my PhD as an advance article in @journal-evo.bsky.social today! David Evans and I present an analysis of feeding mechanics in an ontogenetic series of the hadrosaurid Corythosaurus, the first of its kind in dinosaurs. A thread [1/12] doi.org/10.1093/evol...

Ontogenetic changes in the cranial biomechanics of a crested hadrosaurid dinosaur

Abstract. Mesozoic ecosystems differed from the present in the abundance of large-bodied herbivores that grew through several feeding envelopes, raising th

Some really bizarre anatomy in a hadrosauroid, raising even more questions given the recent Muttaburrasaurus redescription. Congrats to the team!

Putting the finishing touches on the @romtoronto.bsky.social shark workshop! Tomorrow we'll be diving into shark evolution and diversity, from the earliest jawed fish, to Megalodon and the mako. #FossilFriday

Very special #FossilFriday, pleased to announced that we have a new paper out on reconstructing the ecosystem of Dry Mesa Quarry in the Morrison Formation We used modern ecological techniques to quantity and model the ecosystem Feel sorry for the baby Sauropods 😞 🦕🦕 Sergey Krasovskiy +Pedro Salas

I’m thrilled to present the latest work from my PhD! David Evans and I evaluated feeding mechanics in two hadrosaurids from the Dinosaur Park Fm, and the differences were quite exciting. A thread [1/11] doi.org/10.1098/rspb...

Disparate feeding mechanics between two hadrosaurid dinosaurs support the potential for resource partitioning | Proceedings of the Royal Society B: Biological Sciences

The Dinosaur Park Formation (DPF) of western Canada is well known for its diverse fossil assemblage, preserving over a dozen species of large-bodied herbivorous dinosaurs. The high density of large herbivores has raised questions of how these animals were ...

After an incredibly long gestation period, I have a new paper out reviewing all the data and evidence we have on the pterosaurian uropatagium. Full link to the paper is in the blogpost linked below: archosaurmusings.wordpress.com/2025/09/16/t...

Ever wonder what dinosaurs might have sounded like? Courtney Brown and Cezary Gajewski developed Dinosaur Choir, a mix of palaeo and music that turns hadrosaurs into instruments. It was a blast to consult, this opens new doors for palaeo reconstructions... www.fastcompany.com/91291997/din...

This wild new instrument brings a dinosaur back to life

A new instrument called the Dinosaur Choir uses CT scans and 3D modeling to recreate actual the sounds of a Corythosaurus.

A while back we posted a fairly low res. 3D model of a complete skull of the Early Cretaceous therizinosaurus Beipaiosaurus from Liaoning with proto-feathers. sketchfab.com/3d-models/be... Fun to play with. I'm curious if it is printable. @paleontologizing.bsky.social @utahpaleo-ufop.bsky.social

Oh groovy, our paper on the hindlimb biomechanics of the Triassic dinosauriform Lagosuchus is out! A quick thread for now. We uCT-scanned most of the existing skeletal material for this important outgroup to Dinosauria. We sorted through the elements and chose the best ones to make a 3D model from.

New paper! For all of you working with 3d scans (e.g. micro-CT, MRI), check out SPROUT, a rapid open-source tool for generating segmented and parcellated data, meaning your scans are separated into the individual elements without any manual labelling or training. www.biorxiv.org/content/10.1...

Glad to see our latest work on hadrosaur teeth is out today! Gill Gallimore, David Evans, and I did a deep dive into whether hadrosaur teeth are as useful as they seem in phylogenetics. A thread [1/14] dx.doi.org/10.1080/1477...

Individual, ontogenetic, and phylogenetic variation in the dentition of hadrosaurids (Iguanodontia: Ornithischia)

Phylogenetic analyses of Hadrosauroidea are generally well-resolved, but finer resolution within Hadrosauromorpha remains contentious. This lack of resolution is due in part to the inability of dis...
