Manafzadeh et al. propose an approach for combining measurements of 3D articular overlap, symmetry, and congruence into a single metric, and apply this to examine the walking stride of Deinonychus antirrhopus. Armita R. Manafzadeh Bhart-Anjan S. Bhullar nature.com/articles/s4146…

New genome-scale phylogeny of birds! Lots to chew on here, including increased confidence in mostly post-Cretaceous diversification of Neoaves and Mirandornithes as the sister group to other neoavians. The hoatzin is still a problem... nature.com/articles/s4158… #birds #dinosaurs

Morphology of the vertebral column in the Miocene flightless swan Annakacygna ("the ultimate bird"): gmnh.pref.gunma.jp/wp-content/upl… Potential adaptations for stability while floating on the water's surface. Larger species estimated to have been up to 2 m long. #birds #dinosaurs

Look! A job opportunity! I’m hiring a research technician in my lab to work on CT scanning and segmentation of birds and mammals. Apply now if you love vertebrate anatomy: ucl.ac.uk/work-at-ucl/se…. we’ll also be hiring a Postdoc on the project soon.

Another job opening! I am hiring a postdoc in my lab at University College London to work on developing new phylogenetic comparative methods for modeling the evolution of complex phenotypes! Details here: ucl.ac.uk/work-at-ucl/se…

There are few things as exciting in our little corner of science as a new specimen of Archaeopteryx...with a skull...in a major, easily accessible museum! Congratulations to Field Museum & Jingmai O'Connor! These lovely photos are from this great article: bit.ly/44w9Z64

Congratulations to Klara Widrig and Guillermo Navalón on this contribution investigating the ancestral morphology of the bird brain, with a focus on the palaeognath Lithornis. Paper is Open Access: onlinelibrary.wiley.com/doi/epdf/10.10…

🚨 New paper Zoological Journal of the Linnean Society ! 🚨 Early shark relative Acanthodes is one of few Palaeozoic fishes to preserve the gill skeleton, but its mouldic fossils have proved difficult to interpret. In our paper we try and get to grips with this using CT. doi.org/10.1093/zoolin…

Really cool looking study suggesting that airsacs in birds can help reduce muscle work needed for aerodynamic force balancing in flight.

Very pleased to see this out. What started as a grad course assignment turned into a quite large PhD side project! Big thank you to everyone who helped pull this together🙌🏼. Please DM me for a pdf if needed! #passerines #phylogenetics tandfonline.com/doi/full/10.10…

Pretty cool analysis of the cultural evolution of filled pasta (link.springer.com/article/10.100…). Gotta try them all...

At #SICB2025 and really like bird and dinosaur necks? Well good news, I'm talking about all that and more (incl. heterochrony!) at 10:45 today in A601!

Barn owls are remarkable birds, with some of the most amazing hearing capabilities of any animal. Our first paper of the year, led by John Peacock, investigates barn owl hearing physiology: onlinelibrary.wiley.com/doi/10.1002/jm….

Our paper led by Mike Schindler is out #OA in The Anatomical Record. We explore how the craniofacial hinge joint balances mobility & stability in helmeted hornbills, birds w/ high-impact head-butting behavior. Thanks Mason Dean for inviting me to join the fun! anatomypubs.onlinelibrary.wiley.com/doi/full/10.10…
