#2025SVP has begun! Starting strong with the awesome Paleoart Workshop 🎨🌴🦕

If you’re around, come check out our poster about an extinct ibis that basically tried to be a kiwi 🐦🥝

Just in time for #2025SVP, @gsferreira.bsky.social & I have a new paper! We explore the neuroantomy of the early stem turtles Kayentachelys aprix and Eileanchelys waldmani, based on CT scans I acquired long ago during my UK-based PhD times. Flight to B'ham in 2h 🤩🐢

Neuroanatomy of Kayentachelys aprix and Eileanchelys waldmani provide insights into the early evolution of the turtle brain - Swiss Journal of Palaeontology
Even though many early stem turtles are known from relatively well-preserved skulls, their neuroanatomy remains poorly understood, limiting insights into key cranial and ecological transitions. Here w...

The more I work in wildlife monitoring, the more I realise wildlife moves around & often we have little idea why, when, or how far 🙂 ‘Place-based conservation’ makes much more intuitive sense for plants than animals.

To save Australia’s animals, scientists must count how many are left. But what if they’re getting it wrong?
Wildlife monitoring is vital to arresting Australia’s extinction crisis. But research shows we may be getting false pictures of how species are faring.

New paper out from the lab today! Here we show that digital reconstructions of brains from skulls can be used to estimate cerebral hemisphere & cerebellum volumes in birds.

Flinders Palaeo colleagues knocking it out of the park with this paper on short-faced kangaroo extinctions. No shortcuts, just lots of specimens, lots of patience & some fancy microscopes. Chipping away at Pleistocene extinction questions a few species at a time🙂

New study challenges a major theory on why some kangaroos mysteriously went extinct
Roughly 40,000 years ago, the short-faced cousins of modern kangaroos died out. The cause has been the subject of fierce debate.

Happening now! Check out @aub-birdy.bsky.social poster on parrot endocasts at #SICB2025 and get a swift parrot sticker!
A red haired graduate student wearing a shirt bedecked with birds is talking to conference attendees about her poster entitled Just Wingin It. The poster has cartoon diagrams of several parrot species as well as a diagram of a parrot brain.

Well, 2025 is already off to a great start... missed the first flight of the year. But hey, at least I had the extra time to finish this Barn Owl. Priorities, right?

Going to #SICB2025 in Atlanta? Interested in CT scanning, birds, or brains? Some see posters by @evolsara.bsky.social and @aub-birdy.bsky.social on hawks and parrots and pick up a sticker!

Two circular stickers are shown. On the left are cartoon illustrations of Swift parrots against a green background. On the right is an illustration of a front on view of a female northern harrier bisected with the skull on the left and an intact, feathered head on the right.
